[CASE] The first step to take is to select a good case, ideally it is big enough to try to create a flow of air inside and cables through and power up the microprocessor heat sink (sometimes not even fit, depending on the sink that we place) is rather difficult task.
is essential that the case is "solid", ie it is well finished and is constructed of aluminum sheet or a certain thickness to prevent distortion by putting weights on top or move it and eventually started the so annoying and harmful vibrations.
[POWER SUPPLY / PSU]
This is one of the most interesting and can give us better results especially in a team some time.
If you purchased a case of "quality" brand Antec, Thermaltake, Lian Li, etc. and incorporated as a source, not the best of these brands, but enough for systems not as demanding. For a quiet PC is not as important as power in watts would be for a overcloker or someone willing to put 3 neons, although at this point would already have recommended above sources of real 500W.
comparative The only power which also compared the noise they make is that of Tom's Hardware . Although it is in English, which most concerns us is the noise tables and scores .
can also choose to buy a "normal" and change the fan for one a little quieter.
[PROCESSOR / CPU]
One of the major components within our system to be cooled, it is recommended to purchase a third-party cooler if you plan to OC.
The CPU coolers (understood as the combination Cooler heatsink + fan) differs from the material it is made, some are all-aluminum, others completely of copper, and others are a combination of both, ie, the sink can be made entirely of aluminum but contact the surface of the processor may be copper.
temperatures can differ, we have PIV with temperatures at idle can reach 50 degrees, like the Athlon XP, while the Athlon 64 can be quiet at 30 degrees in idle, the C2D Intel also ride in that range as long as they are not OC.
The choice of the best or better ways to cool the processor more on that later.
[DISCO DRIVE / HDD]
This is one of the components that may "frustrate" more because, at first glance, we may think we can not do anything.
First if you buy one, buy one that by itself does not do just noise: I know there are two:
· The Seagate Barracuda with fluid system in the engine .
· The latest models from Western Digital.
A comparison of the noise of HDDs can be found in noise HDDs (Also in English).
However, there is little need to cool a hard drive, its temperature at idle should be around between 35 º -45 º in winter and summer, if the case exceeds those values \u200b\u200bshould consider a solution cooling, this issue touch it later.
[VIDEO CARD / VGA]
In recent years Stock graphics cards come with a cooler "sufficient" to sink all the heat generated by the GPU and memory, some of them even do not refrigerate these components. Here you can find cooler quiet as the loudest, and "passive coolers" that do not include a fan but heatpipes. The theme of the cooling of graphics cards is very broad and we will see later as well as alternative solutions for each set of each brand (ATI / AMD - Nvidia)
[ NORTHBRIDGE (NB) / SOUTHBRIDGE (SB)]
The latest motherboards include a NB and SB, the NB is responsible for managing components such as memories and the processor, while the SB is responsible for managing components such as the IDE slots, AGP, PCI-X, SATA, etc..
Only in the case of OC is recommended to change the stock cooler for a cooler or sink of better quality and better performance when heat dissipation, these solutions we shall see later in article.
[CABLES AND ACCESSORIES]
Proper air flow to the ATX standard is a general rule and outlining, to get cold air from outside of our box by its lower - FRONT and remove hot air after passing through the heat sinks of the components at the top - BACK.
is for this reason that air power removed and are located in the upper-rear of the cases and these in turn tend to have small holes and can be braced for a fan in the bottom-front.
Well one of the things that hindered the proper air flow were the IDE cables and the floppy, we now have rounded cables planes rather than impeding the flow of much less air, so we will not have much air to put the consequent decrease in fan noise.
[HEATSINK + FAN = "COOLER"]
Well we got to the probably more sensitive since a bad installation of cooling or it may burn our processor, we understand by burning it reaches a temperature that is damaged and no longer works.
addition, a silent PC will try to adjust the air flow at the lowest possible flow to keep the components to proper operating temperature. To check the temperature we use the HARDWARE MONITOR submenu that is included in most of the BIOS now, this is very useful when we have installed the PC and operating system have not yet, but once installed it is a nuisance having to reboot to get into the BIOS and see, to see it from Windows there are several SW that allow monitoring the temperature, keep in mind that these SW will depend on the sensor with the board, processor, video card, the hard drives, etc.
- Everest Home Edition or Ultimate Edition
- Rivaturner
- TAT (Intel thermal analysis)
- Speedfan
- CoreTemp,
- own temperature measurement of the plates (Abit guru, Asus Probe II, MSI CoreCenter, etc.).
RECOMMEND correct installation and configuration.
Other articles will touch reviews and comparative of heatsinks and fans.
is also very important the thermal paste (a substance that is placed above and below Processor Cooler), some coolers incorporate a thermal pad already installed, others include a thermal paste to apply, it is recommended get a good thermal paste to ensure good heat conduction by the CPU, such as Arctic Silver 5.
[FANS (FANS)]
We arrived at the heart of our cooling system ... the fans is perhaps the most noise ... though not all, there is the hard drive, but that's another thing.
There are many brands on the market, just as there are many prices, unfortunately, and I do not mean that the most expensive is always better, but is that Computer sadly this relationship holds.
These brands have a Artic Cooling, Evercool, Vantec, Zalman, Antec, Aerocool, Thermaltake, etc. Obviously there is not just this brand of quiet fans, other brands began to take great products to the growing demand for Silent PCs.
should study well the relationship between the air moving (usually measured in cubic meters per hour I CFMs) and the level of noise generated is measured in dB (decibels) ... the volume you need depends on system configuration.
A Recommendation: A large fan makes less noise than a little to move the same air at the same time, that is usually small spin much faster and make more noise so I recommend putting the biggest fans accept us and lower the voltage at which work to reduce noise to a barely perceptible whisper.
As a general note, one 12cm fan (120mm) with sticking to the minimum voltage and one 8cm (80mm) by removing the voltage also should not create only minimal noise and air flow generating more than enough. For this you need a voltage regulator or RheoBus.
