Cooling Efficiency Tests
The results of our cooling efficiency tests are summed up in the diagram and table below:
I have to say that the results of our cooling efficiency tests are not very encouraging. Almost in all speed modes of its default fan the new cooler loses 10°C to the Thermalright True Spirit selling for half the GELID’s price. The comparison with Archon, which price is closer to that of GELID GX-7, is completely pointless. The only thing we can point out in its defense is that its cooling efficiency depends a lot on the fan rotation speed, which we suspected would be the case earlier in our review. When the fan rotation speed increases from 800 to 1970 RPM, the maximum temperature of the hottest processor core drops by 17°C, while with Thermalright True Spirit when the fan rotation speed increases in a slightly narrower interval, from 800 to 1760 RPM, the temperature drops only by 13°C.
GELID GX-7 with two fans performs better, but still not good enough to outdo Thermalright True Spirit, which lowest advantage in peak temperature over GX-7 is 5-6°C. As for the comparison against Archon, the new GELID cooler will have to tame its ambitions here, too. GELID GX-7 with two roaring fans at 2030 RPM lost 4°C to Thermalright’s super-cooler with two fans at quiet 810 RPM. This is a definite fiasco.
During the maximum CPU overclocking tests of GELID GX-7 we discovered that the cooler equipped with one GELID WING 12 PL fan at its maximum speed of 1970 RPM can cope with a six-core processor overclocked to 4400 MHz at 1.43125 V Vcore and the peak temperature of the hottest core at 91°C:
One GELID fan (1970 RPM)
Two Thermalright TR-FDB fans (2040 RPM)
When we install two Thermalright TR-FDB fans onto GELID GX-7 cooler, even at their maximum speed of 2040 RPM we couldn’t increase the CPU frequency any higher, even though the peak processor core temperature dropped by 4 degrees.
Now let’s take a look at the results shows by GELID GX-7 at maximum speed of its default fan compared with all the previously tested coolers:
GELID GX-7 is in the middle of our “tournament table” and diagram, right between Zalman CNPS10X Performa at maximum 2000 RPM speed of its single default fan and Thermalright HR-02 Macho with two TY-140 fans at quiet 810 RPM. The results is quite average.
Now let’s check out the table and diagram with maximum CPU overclocking results for all tested cooling solutions. Besides the processor frequency, it also shows maximum temperature (taking into account the difference in the ambient temperature) and the level of generated noise:
GELID GX-7 is again almost in the very middle of the pack. This results obviously doesn’t match the price of the cooler.
