Deep Cool Gammaxx S40 Review


Deep Cool Gammaxx S40 Conclusion:

The Deep Cool Gammaxx is light weight and easy to install. After you install the S40, you can still get to the various sockets and connectors on your motherboard, and particularly the RAM, which is of course, a big plus. Larger coolers may have high end cooling capacity, but the compromise is that you often lose easy access to your componets. The S40 uses a unique round-frame, 120mm PWM fan and while it looks nice, I am not certain that it can move enough air.

Cooling performance for non-overclocking was toward the middle of the field of test units, but when you stress the system with a mild overclock, the S40 knocks on the 100 °C door, and that is a door we try to stay away from. Two things that I think would help the S40 would be a larger fan with a higher speed to move more air, like a standard square case fan, and for Deep Cool to move the heat pipes away from each other (space them out) to give each pipe better access to a clean stream of cool air.

All that being said, the Gammaxx S40 is a budget cooler and is not likely targeted at systems that are regularly pushed to the thermal limits. So with that in mind, if you don't overclock or push your CPU with a heavy workload for long periods of time, then the S40 does a decent job of keeping your CPU cool.

The fit and finish are top-notch, and the installation is clean and easy. For the average user, the S40 delivers good, quiet cooling performance and won't put a dent in your wallet.
