Many people were torn behind capacity of processors, any more
not understanding, what for it is necessary also what price - i.e.

processor by the powerful fan, they do(make) impossible a life of the
nearest familiar listening to your computer. It concerns not only fans,
the others automatically appeared in this wave and frequently listen to
rather appreciable noise which that your processor which brakes even is
located in your own head. And general productivity of system very strongly
decreases, contrary to the initial purpose.
Good tradition became - neglect such collection in

decided to write down.

Experience is shown that with temperature of the processor, seldom it
happens very big, i.e. is not appreciablly critical factor, and on it(him)
it is possible even to save in every possible way for the benefit of more
important - comfortable conditions i.e. - to absence of noise.
That comes to the first mind - to reduce noise at his(its) source, - and
it is correct.
Having taken into account that concerning the price of a computer,
use of his(its) capacity on the average on 2 % (remember it), and noise of
100 %, is possible to dare to pay attention to comfort of work.
I.e. it is rather desirable to buy the qualitative fan.
How to estimate tables:
Choose Noise level which it is possible to count comprehensible - if
it(he) below 20 ДБ,

audible any more in the case in general less.
I also choose such level. To work it is necessary.
I.e. there is less than sense big has no, at possible(probable) losses in
Though if that does not influence the less noise the better.
Further look at productivity of the fan at such noise depend from теплопроизводства

I think that will suffice 30 CFM on all reasonable cases of a life. It залман.

That there is as why so, in coolers (understanding).

from the point of view of physics,
Examples of oustanding coolers, with discussion of principles of a design,
the reasons of such estimation, with references to especially interesting

is possible to read them after all advice(councils) and their discussions,

That is why it is important:
The processor normally cooled frequently is below temperature
Developments(Manufactures) of a resource for reasonable time, the big
superfluous stock, and it(him) it will be possible to use having
completely a copper radiator.
The idea will be that is possible to allow to be heated up to

If not so thus the temperature of the processor will increase, that is to
make distribution of temperature from distance from the processor more

It can be for example a superfluous layer of aluminium instead of copper

Intel - began to cover a nucleus of the processor with a copper plate,
therefore the some people spoke that it is not necessary to insert

Partly can be and so, but интел

For processors AMD the copper substrate is extremely desirable.
That to buy:
Titan-D9TB Cu35 (10 $),
"Igloo Diamond 4200 " (15 $) - but
aluminium that is bad,
Or Igloo Silent Briese,
(7000-Cu), for 40 $ it is very good, or
AlCu for 35 $ (up to 2800 Мгц).
Firm Zalman specially lets out(releases) the equipment intended for
reduction of noise,
And it frequently is possible to it(her).
- is conventional the best fan - (" the absolute champion ":)
Practically the most effective (among comprehensible),
And the most silent. (among all)
It is considered, among tried and testing in magazines, that it(he) rather
costs(stands) the money - 40 $.
Also there are appreciablly more expensively systems, more
labour-consuming in installation and use (water and thermal tubes).
The open design is good that that in itself well disseminates
heat of a plate in the closed cover, even metal are engaged in an exchange
of heat among themselves, instead of with external space,
As in an open case,
Plus not minimal distance (at the same area of a surface of dispersion of
heat) between plates create smaller resistance to air streams that is
important at small speeds.
Here pertinently to notice about the processor - which really all
time it is necessary what to buy:
It is not necessary to buy especially powerful, except for as for the
specialized appendices such as manufacture of video, or fans of games.
What for to you to listen to noise of single work which at them is

the same processor of firm Intel. (thus you pay for изветсную
the trade mark and the big advertising company enclosed in a trade mark of
the company Intel. And such people the majority. Other distinctions
are not present, - in real appendices).
This processor at desire can be used then as with 2400 мгц
a rating if you want to give children пофанатствовать
on "dispersal", with the some, but not the big risk.
For last games now it is necessary 2500 GHz.
Successful dynamic toys for the greater computing capacity of
system it has not been noticed, and I at all did not hear worthy
assumptions. At me in this sense not original approach (немаргинальный)
the best responses about games.
Recently are planned появитья
beautiful games with good requirements to the processor and a card(map).
The typical requirement: the processor 2000 Мгц.
(Though after purchase of video of a card(map) of generation
bottleneck becomes the processor notice as strongly speed varies at
transition to the fast processor to the majority of tests and as it is
rather not so strong on a new card(map) from absolutely expensive(dear).
However decently - in regular intervals i.e. adequately and pleasantly
displaying a landscape, the picture starts to look with разрешени
1024х. So if want to look well at modern games, choose corresponding
set of the equipment. Me АТИ
8500 and АМД 1600 - does
Now the recommended balance between all factors considers: the processor
of 2600 GHz, (АМД 100 $,
further there is a bend - 170 $ for 2800 GHz.)
The recommended cost of the processor for purchase 130 $ - " purchase
without advertising bends of the prices, enough modern processors ".
Videocard(Videomap): a minimum 9500,
For others - serious players:
Good sites in the West do not recommend to buy a card(map) another than АТИ
9800 not PRO, and other expansions SE..., (also name an optimum choice
between all factors), as or will appreciablly lose in the long term
for new games, or overpay absolutely необосновано
- and all of them began expensive(dear).
The recommended cost optimum видеократы
for purchase was 100-130 $, now earlier
150$ - For quite sufficient "now" necessities for games,
260$ - In view of prospect.
So the optimum choice as in processors - is not present, anyhow it is
necessary to overpay.
Arguments to fans(amateurs) to argue on price
Intel uses such policy(politics) in the prices:
The gain of the first place in race of processors especially means
nothing, for the same reason, if it occurs not for especially long term:
Already having the greater financial potential than the competitor, they
stake on two things: on масированную
That in result bought their processor without dependence from the price.
And besides the policy(politics) "adhered" i.e. almost силововых
with the main dealers and trade marks so him(it) it is favourable поддерживатьсвязь
with one supplier refusing from a choice, as though having fallen in a
potential hole of price discounts is popular thus.
Or it is directly expressed in a skew, in this situation -
benefit, to the owner double force привызанности
is more than discount to the dealer provided that it(he) will support
higher total prices, double to it(him), plus the competitor does not rise
and provides a competition. That certainly to all in result harmful.
So in result one leading company receives the main market
share irrespective of the price and parities(ratio) price / quality.
And as a result you overpay for " the known trade mark " which
is better nothing, in spite of there is nothing - on any reasonable
arguments. Though Intel not so злостен
in this question as Nvidia.
It is difficult for competitor to compete as to it(him) difficultly to
rise all over again up to such level of advertising and sales as an
opportunity to make.
A little bit exclusive policy(politics).
Further I think optimum to choose the processor with the
balanced parity(ratio) of a thermal emission, the price and speed, and
speed not on the first place as for last models of firm take money from
advertising reasons and for novelty, and obviously do not cost(stand) запрашиваемомго
About " technically different processors ":
By the way САНДРА,
not last test - also shows a rating on productivity:
АХP 1600 = P4_2000. (one year ago, and processors
of such names and now)
Hint at that that especially Атлон
is fast on usual - not SSE appendices,
What majority - unless it is bad?
And on SSE almost as on a rating.
It is those there is a force of advertising that equalizes speed of
different processors, or accelerates for eyes of the user - not best.
But, so was earlier, therefore I have decided to not erase,
Intel since then was not bad tightened, - but only for the senior models
with a cache 512 кб and a
rating it is more than (=>) than 2.8 GHz, according to the same
сандре-2003, and these processors on
the average, taken on all to tests, are identical.
Or you can get the mobile processor, more
dearly(expensively), seldom but to not make heat - (to not spend energy).
This decision - for solid people to which 100 $ superfluous for
comfortable work it is not a pity. (But фанатеть
will be any more above what. It is necessary to work.)
(Desctop replace model. Take an interest all the same in a relative mode
of a thermal emission of this processor, there are different models. And
his(its) compatibility with modern sets of microcircuits of parent
Necessarily put the specialized program for cooling - she(it)
will not allow the processor to allocate the majority of heat in a single
CPUIdle or CPUCool. Reduce temperature on 10 degrees or in 2.5 times
differences with room in a single mode. In the worker - notices loading
and speed is disconnected also is not lost. Very useful thing.
Or there are other free-of-charge good programs. (Процесор
it is designed for fluctuations of temperature and will not suffer, if it
is not done(made) specially and many months.)
For the given way - installations of adequate balance of temperature and
regulation of noise, - rather desirable program.
As a rule, having put such good cooler you receive the big
stock on темепературе
in view of that that the processor should work 5 years, and it turns out
(Really, speak - never will break)
Therefore further the most important advice(council) is to insert
the variable resistor face value 80 ohm into a circuit of the fan, to have
an opportunity to reduce revolutions of the fan in 2 times. Into complete
set Zalman such enters.
The processor for example Intel, starts to be in a zone перегрева
with 70С, and is switched off on 110С, being is alive,
Therefore the operating conditions during long full loading is supposed in
offered(suggested) system - 60-63С, and in single 40С. Adjust
the payment on 65С temperature, preventions(warnings) and 70С
If you for the period of games, will tighten up a regulator
of the fan problems in general it will not be close. And the rest of the
time will be silence and a cold.
If presume to itself Zalman in a configuration on having
blown (7000) is
simply optimum variant for all system (would be),
But good only for especially active system as appeared, выскооборотной
which just is not necessary for us:
As warm air is thrown out at once from the case, but costs(stands)
hardly more dearly(expensively). (it is Bad if more than 50 $ - then it
for fans, - since usual will suffice, or it is better to think - of a
(The distance up to the removed branches of a radiator if it(he) copper,
it is almost imperceptible)
(Example of good technology, for fans(amateurs), details:
Speak that, installation of a stream on having blown from the fan,
is less effective than a forcing, it is possible to understand it delivery
of air almost to destination of a cold to a plate of a sole of a radiator,
and on the big speed for maintenance of good contact of air and
plates - "directly" (though is more often to speculate it is not
necessary on this concept), is favourable, also the vortical condition of
air for the best heat transfer from him(it) here is provided, and blown
fans as a rule have such feature that it(he) blows all from the nearest
cracks, and at all from the basis, - however not the direct effect here is
applied - air passes only from below between densely located plates,
that not bad eliminates a usual inefficiency of remoteness of a place of
cooling from a stream of air, plus air pressure in it(him) is used more
optimum than usually - the centrifugal streams usually appreciable,
here are not lost as usually, and are used quite to destination -
blow in same plates, But hardly above on height than a place of an
input(entrance) of air, it is shown especially effectively, that it is
done(made) by wide blades on the ends. So in the top part of a radiator it
is formed air bank which and at the level cools - pushes aside a cold
stream again on walls, but the main thing increases used air
pressure, reducing diameter of a cold stream so his(its) speed in
especially necessary place - below increases to what coolers aspire.
And thus each part of energy of an air stream (from the fan) and
his(its) colds is used practically optimum for process of cooling.
Plus certainly - in such system it is easy to throw out heated up air at
once from a computer, having reduced the general(common) temperature. In
view of good efficiency of the decision even only for the processor, it
similar on usual CNPS6000-Cu, is possible to reduce speed of rotation -
and to receive benefit in reduction of noise.)
The problem in such decision - at low revolutions moving of
air has диффузионный
or in соновном
mixing around of a place of rotation character (that in other cases only
and it is done(made), but is active also it suffices.), instead of потоковый,
therefore a conclusion of air for limits of the case in general низкоэффективен
at such revolutions, as it has been shown in tests for a cooler 5100. In выводном
an air line it is difficult to do without the additional fan, besides it
is more warm, already rather big in comparison with the processor in such
mode, the hard disk and a videocard(videomap), therefore the circuit of a
воздухо-channel through all
computer start to allocate is represented more адеквтной
than only through the processor block - the general temperature in the
case can raise(increase) simply appreciablly because of them isolated from
воздухо-streams, without the
reasonable purposes, that it is not necessary to us - necessary to protect
a hard disk.
Non-uniform noise can excite you - but the processor, as
against a videocard(videomap), together with a massive cooler inertial in
this respect the thing, therefore loudness really increases during serious
appendices, such as dynamic games, thus smoothly enough and adequately to
the appendix, instead of his(its) stages.

But here have invented one new,
As at small thickness 25 microns if to compare to a radiator of 1 sm,

Now with you have remained to rustle much more loudly fans of the

resistors face value 100 Ohm and to brake them thus.
Cut also lattices above us in the case as they detain air, and put cheap
wire (or do not put if be afraid for whom from children beside).
Good mode of an air pipe:
The fan in БП - on having
Under it(him) - on having blown.
(Air passes on a circle without a delay,
As it happens by simple forcings in the case from different directions.
Plus directly cold air moves to area of the processor and the winchester
As seen result - after loading the processor is cooled in 2-3 times
Plus one more of 92 mm the delayed fan it is necessary to hang up making

been described, it is necessary to cool the winchester in the first.
Therefore the fan under БП, can
drive air to the case simply freely. The effect of a pipe for air in a
critical place is kept. (Without air a proside).
You have braked all of them, but is all the same a little bit
And the understanding of appetite (приятности
result) comes during such meal (here this experimental). Though on the
other hand we not fans.
I.e. further you should soundproof the case:
It is necessary to know that the sound will consist of two components -
low frequencies, and high, (and certainly any average). All is necessary
to block them.
How to block a way of a sound on the case and to it(him):
The processor fan should be planted(put) on a soft lining, and to fix a
wide elastic band.
To put on a skirt the big fan to direct all stream to a small
The jet stream hits about walls of a skirt, is reflected from them, mixs
up and loses a direction and reactance-скорость-there
is only some pressure, and охлждение
then it is favourable when the stream hits about metal of a radiator,
therefore better simply to direct a stream from a regional part of the big
fan on your small radiator.
But have thought up the following:
Not only in the general(common) air pressure happiness of the fan,
and and in its(her) orientation.
(It on mine - than still плох
Аэро-7, at тоо
all in the pure(clean) not directed pressure)
Times more at the fan of all speed of a stream means, it is possible to
optimize her(it) also so:
Usually centrifugal forces on dispersal of air have very quite good
energy, and it is possible to use her(it) as Zalman 7000, and possible сделат
ьтак that she(it)
did not harm in a usual design of fans - the matter is that the jet aside
hits about a wall of the case of the fan, reflected, dissipates, mixing up
downwards - and accordingly forces down her(it), reducing speed to avoid
this effect have decided so - to cut horizontal strips in the case
of the fan that it is often ьвоздуха
left in outside of, not creating an aggressive air pillow, and stayed
created soft - forming only an air wall forming a stream so to give to a
stream an optimum way - without dispersion to a radiator.
It is a little exaggerating about the same as close light from a
bulb (it рассеиваемый
light) and light from a headlight with the same bulb (optimum directed).
The case оклевается
(from him(it)) a material, - it(he) "takes away" a sound, (if
did not isolate the fan of the processor from the case) - everywhere,
except for a back wall a little,
Then soundproofing, this does not pass(miss) a sound from the case..
The size of the case is not less miditower. Otherwise it will
be inconvenient to establish and check all, and bad cooling owing to
narrowness - is provided.
For full integrated approach it is possible to paste over
from within still with a sound absorber - for absorption of a sound inside
the case, but it for fans.
Characteristics of materials allow or sellers, or in the
specialized repair trucks.
Good sound absorber (not isolator) - a complex(difficult) thing, a
sound from all it is good отрается.
Choose a combination of materials overlapping all sound range from 50 up
to 5000 гц, it is the basic
"The muffler ": (for absolutely full integrated

it is more to swallow up this sound, just in a place of his(its) passage.
Speak that helps a little, if you yet have braked all, in what case
the sound will be already through the case распостраняться.
If have made the rest this thing can not be demanded.
Important - do not buy the Chinese case, - will not calm down, or
still any problems receive, primitive Chinese hooks of fastening will not
break. Buy, for example, Inwin with 300Вт a power unit and two

The guarantee on components is better for keeping.
Appeared that 85 % of effect (the decision of a
problem of noise) can be received with the help of 15 % of efforts -
simply having braked all fans, having chosen the good case and components

having paid at all it is much more, and повыбирав

It is possible to try "to scratch" plates of a cooler to
achieve their best contact to air.
(As it is necessary to scratch! - in cross-section to air a direction. But
then it is necessary to take care of a filtration of a dust before a
cooler or the case (always it is useful) which not bad is late such

lengthways there is less than dust, and the effect hardly is less. Де

People sawed the radiators, through, that similar on this
case actually (принципп
the same, but all received casually), and reported about successes,
(in any case, naturally. This fans). Some official designs suggest, that
this idea is quite used in "highly effective" radiators.
Such effect is noticed here:
At corners of the fan the internal surface is oblique,
And when in it(her) air hits, тоон

And in the big volume,
Than in the middle of a side of a limiting framework - as there air is
As the framework is not oblique usually in this place.
I.e. if to cut out half of framework on the party(side) of an output(exit)
in the middle of a side, or to make an incision and incline, lines there
are directly specified how to cut out better, the stream will increase
appreciablly as centrifugal energy is rather great in a stream.

Though for small speeds it also can seem important.

And so that simultaneously of this system some systems inside a computer -
the winchester most critical of them could take advantage. Thus holes in

Thermal tubes are very powerful and quite good steel, thus it

They compensated here uselessness of copper in plates as on far distance
from a source of heat it was unimportant that cools aluminium or copper.
This justified application трубок.
All components work proportionally to their cost and purpose(assignment)
supplementing each other in weak places.
I.e. copper is really important at теплоисточника,
and further the area if a design classical, without трубок.
I.e. 10 % of a prize copper give (T_change/T_processor-T_ambient (68-63) /

Though for an average level - 2500 Мгц,

Why it is a lot of the fans designated as

Aluminium or Copper? - for low speeds.
Copper in plates is important there where dynamics(changes) of heat
conductivity should be raised(increased) according to activity of

There where calculation is under construction on the area охладения

The dust completely presses a coordination of a jet and brakes her(it).
