ASUS Triton 85 CPU Cooler
 

The ASUS Triton 85 CPU Cooler is not only a great looking piece of hardware that you could get to help cool that processor of yours, which keeps overheating from the stock cooling solution, it is also able to run very quietly, between 16 and 25dBa. I was very impressed with how silent the Triton 85 was; when it comes to some of the other 120mm CPU coolers that are out on the market, the Triton 85 seemed to be the most silent. Even with the silent operation of the cooler, it was able to keep the processor from overheating and kept it pretty cool when compared to some of the other coolers. When you put it up against some of the other proven coolers, especially the other 120mm HSF Solution, it did not triumph, though it did hang in there at just a few degrees higher.
