Silent videocard Gigabyte GV-RX16P256D-RH

Evgenie Rudometov

Applying the firm processing techniques providing usage of several heat sinks and thermal handsets, company Gigabyte has released completely silent videocard Gigabyte GV-RX16P256D-RH

Modern high-powered computers demand adequate video subsystems. Necessary thermal modes of their operation are usually provided with appropriate resources — coolers. As a part of traditional coolers in addition to metal heat sinks use as well high-speed fans which owing to the operation are powerful sources of acoustic noise. However thanks to application of current technologies variants of cooling systems and without fans are possible. As an example of one of such solutions it is possible to result videocard Gigabyte GV-RX16P256D-RH created on the basis of video chip ATIRADEON X1600 Pro.

Features of construction Gigabyte GV-RX16P256D-RH

Widespread resources of cooling of the high-powered video chips, consisting of the heat sink and the fan, generate considerable acoustic noise. The given noise is the negative factor. With it implementators of all computer components, forced to use traditional coolers try to struggle.

However there are also the alternative variants which are not providing usages of fans. For example, maintenance of the video chip of a temperature mode necessary for correct operation can be reached by means of the several compact heat sinks jointed by special heat-conducting handsets. Such handsets have received the name thermal (Heat Pipe).

The principle of operation of thermal handsets is grounded on thermophysics of transformation of the liquids concluded in hollow handsets, vehicles of transmission of thermal energy playing a role.

Specially picked up liquid under the influence of heat derivated, for example, from operation graphics or central processor units passes in a gaseous state. Thus at the expense of transformation heat considerable quantity is swallowed very much.

In a vaporous state the liquid reaches the cold end of the thermal handset jointed to the heat sink, disseminating heat. At the expense of cooling the liquid in a thermal handset is condensed, giving heat to a handset, and from it and to the heat sink. At this stage warmth of steam formation comes back back through the heat sink in environing air environment.

It is necessary to mark, that the internal surface of the hollow metal handset playing a role thermal, is coated by special capillary-porous substance. skondensirovavshajasja the liquid at the expense of forces of surface-tension through the given porous substance gets again to hot area.

At this stage the cycle is ended to repeat again and again. It also ensures functioning of the thermal pump which role is fulfilled by the described thermal handset handling thermal energy from the protected semiconducting unit to the heat sink. It is necessary to mark, that such handset is capable to handle thermal energy in considerable quantities and with a high speed.

Usage of thermal handsets allows to create constructions from the several heat sinks jointed together. Such construction is arranged optimally on a surface of a videocard for the purpose of effective dispersion of heat taking into account existing air streams. She allows to support a necessary thermal functional mode of accessories of a videocard in the absence of acoustic noise.

Such construction has been taken as a principle systems of cooling of video chip ATIRADEON X1600 Pro (ATI X1600 Pro) videocards Gigabyte GV-RX16P256D-RH. A method of cooling by means of the given construction consisting of several heat sinks and thermal handsets, it has been named by experts Gigabyte processing technique Silent-Pipe.

The turned out video subsystem is completely silent, that raises its attractiveness among potential users.

The specified construction of cooling well functions in an open system unit. However its efficiency essentially raises in case of usage of streams of air, obrazuemyh at the expense of existing case fans. The additional stream of air forms thanks to rotation krylchatki the fan of the central processor unit allocated in immediate proximity from a videocard. This stream together with the main streams generated by case fans, cools the heat sink of a videocard allocated on its underside even more. Thanking presence of a thermal handset cooling and the heat sink on frontal to the side is carried out, well and through it — is direct also the video chip generating a considerable quantity of heat.

As to productivity of the specified videocard it has been estimated in the course of intensive testing.

The cited data do not require remarks and testify to high efficiency of videocard GV-RX16P256D-RH.

In summary it is possible to recommend the given map to a wide range of the users aspiring to silent, rather high-powered systems.
