Thermalright SLK-900A Copper Heatsink Review
Thermalright SLK-900A Copper Heatsink Review
  85%   
Abstract: The SLK-900A ships without a fan, but that flexibility allows you to determine just how loud and annoying the heatsink will be.

Even though the SLK-900A and recently reviewed SK-7 were equipped with the same 80mm fan, we can instantly see that the SLK-900A is achieving better temperature results already. Let's jump ahead and find out how the SLK-900A performed thermally.

With the same fans, and similar body size you might expect the Thermalright SLK-900A and SK-7 to perform very close to one another, but it's clear from the final results that the SLK-900A is simply the better heatsink.

Even with the large 80mm fan that was selected for its noise characteristics, it is clear that the Thermalright SLK-900A is still on the cusp of being labeled a performance heatsink with respect to the 100W small die thermal test. With a higher speed fan it would most certainly climb to the very top of this reference list.

Ultimately, the Thermalright SLK-900A is a very good heatsink, and one I would recommend for AthlonXP users looking for a little extra from their system. While it is possible to use a very large and high speed fan to further increase the thermal performance results, say for overclocking, I don't see that as a really feasible option outside the test bench.

After a few minutes of gaming, or overclocking, I'm sure most of us would be apt to shut down the PC and swap out the loud fan for something a little quieter. With that in mind, an 80mm fan like the one we used for testing would make for a good combination with the Thermalright SLK-900A.
