Cooling Efficiency on Leadtek GeForce 8800 GTS 512MB

Don’t be surprised that here we are going to test our cooling solutions on a GeForce 8800 GTS 512MB and not 8800 GT, which weak cooling system we mentioned in the very beginning of this article. You all know that graphics processors are the same and the cards differ minimally from one another, but 8800 GTS 512MB dissipates more heat than 8800 GT, and hence should be better suited for the purposes of our today’s test session. However, I can’t disregard the fact that we will not be able to compare the obtained results against those of a default GeForce 8800 GT cooling solution.

For our experiments we picked a Leadtek WinFast PC8800 GTS 512MB graphics card with a reference cooler that looks like this:

We managed to overclock this card to 756/1877/2052MHz with its default cooler and Arctic Silver 5 thermal interface.

Here we have also added the results for Cooler Master CoolViva Pro SE cooler that wasn’t tested on Radeon HD 3870 for objective reasons. Here are the obtained results:

Of course, you can see that AeroCool Double Power will not be able to replace the reference GeForce 8800 GTS 512MB cooler, because it is less efficient in quiet mode for both: the CPU and the card in general, and at maximum fan rotation speed is not only efficient enough but is also quite loud. Those who value quiet operation should pay attention to Arctic Cooling Accelero S1 with Turbo Module as the most efficient and also very quiet cooler. It’s a pity that Accelero S1 cannot cope with a hot GeForce 8800 GTS 512MB in passive mode (without the Turbo Module).

If you are looking for maximum cooling efficiency for your GeForce 8800, you should consider Thermaltake DuOrb or a more “flexible” Zalman VF1000 LED with adjustable fan rotation speed. Even the GeForce 800 GTS 512MB reference cooler will do in this case, although you will have to sacrifice your acoustic comfort for the sake of this efficiency.
