Cooler Gigabyte GH-PCU21-VG (3D Cooler)
In 2003, the industry is cooling devices has made a big step forward. Cooler manufacturers have managed to solve the problem of adequate cooling of processors, and began to pay more attention to other parameters, such as noise, ease of installation and appearance. I want to stress the success of Zalman, which initially released CNPS-7000 cooler (-Cu and-AlCu), and then an improved model of the CNPS-7000A. This product has an impressive cooling performance at very low noise level. In addition, it can be installed on all popular platforms (SocketA, Socket478 Athlon 64) and has a speed regulator. However, Zalman 7000-Cu is the champion in the field of cooling: the title away from him heatsink Thermalright SP-94. The reason for this victory lies in the use of “heat pipes”, which can increase the efficiency of air heaters.
At the end of 2003, the market has a new Cooler: Gigabyte 3D Cooler. No doubt it was a great marketing ploy: a very long time motherboard manufacturers were not paying attention to the cooling system. The only thing we can think of – its cooler equipment and production of MSI mainboards is very popular (at the time) cooler Asus FSCUG9C-6FC. How do we then discovered, Asus was not a direct manufacturer of the cooler – it just ordered it on the side (OEM order). But as it is now admitted Gigabyte is not clear: perhaps it has ordered its OEM-suppliers, and probably opened his own department for the production of cooling devices. The latest version is even more likely, since it is no secret that the production of various computer accessories bring a handsome profit.
Complete 3D Cooler
But anyway, a cooler in our laboratory and today we will test it thoroughly . First pay attention to the packaging: it is made of transparent plastic with numerous cardboard inserts.
Inside the box you can find a lot of components.
Cooler Gigabyte 3D Cooler;
Fixture for motherboards Pentium4;
Hardware Motherboard for Athlon 64;
Fixture for motherboards Athlon XP (SocketA);
A tub of proprietary thermo paste;
Speed ??Control + cap for zadnuyuyu panel of the housing;
Installation instructions for 10 (!) Languages;
Power supply adapter.
Central to the configuration is manual. And it is not surprising: the cooling system sometimes take a rather bizarre form, and without instructions with pictures to install them is difficult (to say easier countrymen – “without a pint is not to put” . However, installing the Gigabyte cooler is intuitive and user does not need (the more the quality of the translation into Russian is poor).
Next, a proprietary thermal compound Gigabyte (we will evaluate its effectiveness later) and cooler in person. These high figures may turn out not only because of reducing the number of failures in IT, leading to downtime and financial losses to business, but also thanks to the efficient optimization of human resources and internal processes of the company. In some cases the proportion of direct cost savings from reduced labor costs of 10-15%.
The design of 3D Cooler
Now go to the fastening. To install the cooler on the motherboard, Pentium4 processor uses two metal clips, which cling to the plastic frame of the socket. As for the motherboard for Athlon 64 processors, we evaluate the efficiency of mounting the cooler, we could not: though such cards for a long time gathering dust in our laboratory, the appropriate processor, we have not yet received. But with mounting SocketA-fee situation is simpler in every way: a relatively small weight of the cooler has allowed developers to use the mounting clip with 6 hooks at the teeth of the socket.
As a result, this cooler can be installed on virtually any SocketA fee, except for those boards that have the power module capacitors are very close to the processor socket.
In this regard, the Gigabyte 3D Cooler is much friendlier to the user than the Zalman 7000A. As the attentive reader remembers, Zalmana cooler mounted on the board, which must have mounting holes on the sides of the socket. A majority of motherboard manufacturers abandon this feature. As a result, this cooler is installed without a problem only in very few mate. boards (for example – Asus A7N8X rev2.0). And many boards though, and have mounting holes, but to install the cooler Zalman 7000A must be shortened (hacksaw mounting clip. As a result, a further upgrade to Socket 754 platform, the cooler it becomes useless.
Thus, the installation of the cooler Gigabyte 3D is a very simple and is carried out without any problems. The only time – krezhnaya clip SocketA platforms do not have a fixed position, resulting in a cooler can be installed with a little skewed. Example:
But to avoid this is very simple – you need a clip that held the exact center of the socket.
As for mounting on Socket 754, it is by using a longer clip, which has a plastic lever-lock. Finally, install the cooler on the CPU Pentium4 by using two metal clips.
In fact, the method of fixation is the only technical thing that unites Gigabyte 3D Cooler with other coolers. And the rest is a completely unique creation . However, if we look in detail, there is nothing new Gigabyte engineers did not invent. By order of: the heat is absorbed by the processor intensive carefully polished copper base.
The processing quality of the base – 9 out of 10. And to prevent scratches, it is a sticker.
Next, heat is transferred very quickly to two heat pipes. And the tubes are bent so that heat is transferred both ways (ie eyes, we see four pipes . As a result, twice the increase of their efficiency.
But the tubes themselves are unable to transfer heat to the environment (a very small surface area). Therefore, the tubes are put on about 50 thin aluminum plates, which multiply the surface area. As a result, the total weight of the cooler is small – only 430 g. In principle, this allows you to move the system unit without removing the cooler (with the same Zalman 7000A I did it very carefully).
However, the large surface area – not a guarantee of efficiency. A very important role played by the contact thermal conductivity of heat pipes and fins. And here we are waiting for disappointment: contact “dry” – that is, without any thermal paste.
Thus, the design of the radiator cooler GH-PCU21-VG (3D Cooler-Pro) deserves a solid 4 +.
