Modern high-powered units and computer sites are characterised by a considerable heat release that demands the adequate resources providing temperature functional modes recommended by implementators of accessories.

The choice of hardware of support of necessary temperature modes is expedient for starting from computer tank. For the architecture of modern computers the optimal are tanks of standard ATX. Thus, considering a high heat release of the units maintained in forced modes, it is expedient to be oriented to type tanks mini ATX or even more volume midi ATX, providing the best temperature mode for accessories of all system.

It is useful to supply the selected tank of the computer with additional fans which provide lowering of temperature of air in used tank. It raises an overall performance of local resources of cooling of electronic parts of the computer. Heat sinks and the cooling fans installed, for example, on the central processor unit, a chip set, videoadapter chips concern such local resources.

Since processors 486DX2/66 heat sinks (heatsinks) became the integral data attribute of units. It is linked by that together with growth of computational capability of processors their heat release, as a rule, grows. According to it it is necessary to increase the size and effective square of the heat sink. But, despite all reasonable efforts, the processing techniques of semiconducting production linked to improvement and perfection of the architecture of chips, a heat release of high-powered units increases fast rates. Therefore already from Pentium processors in addition to traditional heat sinks began to mount special cooling fans. Such resources often name as coolers (from English cooler — the cooling arrangement).

Further the tendency of usage of the coolers providing maintenance of a necessary temperature mode of maintenance of high-powered units, has captured also the videoadapters which basis is made by video chip sets. It is necessary to mark, that on internal complexity the newest video chip sets concedes to modern processors a little. Created on similar processing techniques, they, as well as processors, also demand intensive cooling without which their maintenance, as a rule, is impossible.

It is necessary to mark, that in addition to the specified resources for improvement of the thermal contact electrode of tank of a cooled unit with the heat sink attached to it it is expedient to use the special thermopastes released as the domestic industry (for example, КПТ-8), and foreign (for example, Arctic Silver). Alternatively or additions to thermopastes can be used appropriate thermofilms. The given resources — thermopastes and thermofilms eliminate an air slot between tank of a cooled unit and its heat sink. It promotes the best transmission of heat from a protected unit to the heat sink and accordingly more effective cooling of the given unit.

So, usage of heat sinks provides the best temperature mode of maintenance of electronic parts. Heat sinks increase heat exchange of cooled units, for example, the processor, a video chip set, etc . With a surrounding medium. It is carried out at the expense of substantial growth of square of a cooled surface in comparison with square of tank of an electronic unit. The more the heat sink square, the dissipates through it of warmly cooled unit in environing space more intensively. There are the various manufacturing techniques of heat sinks influencing its quality. However it is necessary to mark, that qualitative products, as a rule, are not only effective, but accordingly and rather expensive units. But, as a rule, such units are the optimal components of systems of cooling.

Heat sinks are usually made of aluminium — the cheap substance well leading heat. Copper, of course, — is better, but this substance essentially is more expensive. Besides, a specific gravity of copper it is considerable above, that leads to increase in weight of the heat sink and complicates a problem of its mount.

From physics it is known, that bodies of dark colours ray heat better the light. For this reason at a choice of the heat sink it is necessary to give preference to heat sinks of black colour though for giving to the products of more advantageous sort manufacturers use colours of gold and silver. But black colour is optimal. However it is necessary to pay attention that black colour is reached as a result of application of the special processing techniques linked to etchback in chemical, a sputtering of special substances, etc . And, of course, the due result cannot be reached by means of usual black colour which is faster a thermal insulator, than an explorer though there is also such coating. Certainly, it concerns bad quality products, as a rule, from unknown manufacturers.
