Coolers for Intel LGA775 processors

Coolers for Intel LGA775 processors


In the years 20042005 erupted with renewed force “battle” between manufacturers of processors and cooling devices. The first (and to be precise – the company Intel) has released new processors with a TDP of them (older model) can not handle even a “boxed” coolers. The second started desperately to develop coolers with huge radiators or heat pipes. A complication of the structure led to a natural conclusion: the coolers are expensive. Some models have already crossed the bar for $ 50 and come close to $ 60. And you can not raise the price: 90 $ -100 $ you can already buy a water cooling system (and some manufacturers are promising to produce “dropsy” for $ 30 – see review Cebit 2005).

Anyway, we got the impression that even with the use of heat pipes, the efficiency of air-cooling has come to its technological limit. And the further development without increasing the cost of food is almost impossible.

From the perspective of the average user, the crisis of air cooling systems are also evident. For no cooler is able to provide reliable cooling of high-end processor in a silent (or close to that). And the fact that the system unit, howling like a vacuum cleaner is presented as a triumph of advanced technologies – this is another proof of the powerlessness of producers coolers (or conceptually wrong architecture of CPUs).

Well, if you look at the cooling system in terms of overclocking, they have no choice but to switch to water cooling system. For almost all of the latest Prescott processors for LGA775 socket can easily overcome the frequency of 4 GHz, while consuming (and therefore highlight) from 130 to 150Vatt energy. And how sick was not the head of overclockers (in a good sense of the word – himself a :) , they also want to quiet operation of the system unit. From this point of view, none of the products tested today does not meet the requirements of overclockers.

However, there is a catch: Many manufacturers of coolers to get good results using a fairly noisy (yet powerful) fans. As a result, the temperature graphs, we see value in the region of 50-55C, indicating that some margin for increasing the frequency of the CPU (remember that the emergency mode Throttling is activated at a temperature of about 70C). However, the noise of fan running at maximum speed, rumble like an airplane and use it in this mode can only be a short time (without prejudice to the hearing).

Gigabyte G-Power

Gigabyte continues to expand its line of cooling devices. Following the highly successful series of coolers 3D, the manufacturer presented to the public a brand new model – G-Power. Its design is rather unusual, and it uses well-proven heat pipe:

The cooler comes in a big plastic box with transparent window.

Inside the box you can find the following components:

Cooler Gigabyte G-Power

Universal mounting kit

A tub of proprietary thermo paste

Braces in the expansion slot

Speed ??Control of 3 “panel

The controller is the speed controller

Installation Guide

Fastening frame for LGA775 socket

The appearance of the cooler is impressive: from the aluminum base are the four heat pipes which are mounted in a large aluminum heatsink.

Right on the radiator 110 mm fan with casing of blue plastic. On the frame are four blue LEDs, which, when cooler effective illumination.

With the controller, the user can change the fan speed in the range from 1700 to 3200RPM. When the noise level varies from 21 to 40dBa, and the air flow – from 36.2 to 68.5CFM.

The total weight of the cooler is 430 g, which is relatively small. The small weight of the cooler, and secure attachment to the socket allows you to safely carrying the body from place to place.

Take a close look at the bottom, rear side is a very intricate shape. This is done to ensure full universality of the cooler. In particular, Gigabyte G-Power is compatible with all popular platforms: Socket478, Socket939, SocketA (Socket462) and SocketT (LGA775). If you are installing for the first three types of motherboards, various clips and mounting the cooler on a socket LGA775 motherboard, you must first install the plastic mounting frame (construction of which is completely analogous to the frames used for the installation of coolers series of 3D Cooler).

Installation of the cooler on the motherboard does not cause any difficulties. But if the user is inexperienced, then he will come to the aid of guide, which contains a great number of illustrations, and text presented in nine languages.

With regard to the processing quality of the base, it is satisfactory:

The cooler is equipped speed regulator unit, which can be connected either to the regulator 3 “panel or knob on the bracket (which is installed in place of an expansion card).

I want to stress very low noise level at the minimum speed. According to this parameter Cooler Gigabyte G-Power can compete with the products of Zalman. However, if a hand on the radiator, you can feel the vibration of a fairly large, indicating that the average fan as a balancing (ie Gigabyte could have done even cooler is quieter). At full speed the cooler noise is quite tolerable, and at mid-range comfortable operation is possible.

In conclusion, I want a photo of the cooler G-Power, installed on the motherboard Gigabyte 8AENXP-D (on the chipset i925XE):

Incidentally, the DPS module is installed without any problems:


Universality (installed on all popular platforms)

Excellent appearance

Low noise level

The presence of two speed controllers

The presence of thermal paste included

The relatively low weight

Easy to install

Excellent cooling performance.



P.S. In addition to traditional air-cooling devices, Gigabyte plans to release its own water cooling system. For the first time she “lit up” at Cebit, and on Junes Computex was shown a complete product.
