AMD Wraith Prism CPU Air Cooler Review

AMD has very much upped its game with the latest generation of Ryzen processors. The Ryzen 2700X comes complete with a snazzy looking cooler that has served us well on our test bench, but what happens when you put it inside a hot case with a hot video card and put the screws to it in terms of GHz and wattage on our 4GHz Ryzen testing rig?


Results: Temperatures

Testing will be done on our Ryzen 7 1700 processor overclocked to 3.9 GHz at 1.475 volts. This represents a very high wattage load. The software used for testing will be Prime95 v29.3 with SmallFFTs for the CPU load. We found Prime95 with Small FFTs load to give us repeatable results, as well as being the preferred load testing software for some major hardware manufacturers. FurMark 1.19will be stressing the GPU in the combined test, and everything will be monitored using HWiNFO 64 v5.57, and AMD's Ryzen Master. You can see our full explanation of system build-out and testing procedure outlined in this article.

We will be performing two, one hour test runs, one with Prime95 only, then a test with Prime95 and FurMark running simultaneously, both inside a closed case. Temperatures from the "tdie" sensor, as well as all hardware thermocouples, and package wattage will be recorded every 5 minutes.

We will be testing for the Wraith Prism twice, due to the switch we mentioned on the previous page. AMD calls it their "fan overclocking control" and what it does is changes the max speed from a fast 2,650 RPM, to a finger chopping 3,600 RPM.

On the high fan setting the AMD Wraith Prism performed surprisingly for a stock cooler, running within a few degrees of several air coolers we have previously tested. On low however, it is a different story. 96C is usually the upper limit before our test platform starts having problems, and on the low fan setting, the Wraith Prism skirted that line the entire hour, but it did pull off a successful test run.

In the combined test, the difference between the high and low fan setting was our test platform crashing in withen 4 minutes, or 2 minutes, making these the fastest failures of the combined test we have so far recorded.

Sound Profile and Loudness

Sound testing is done from a distance of 4 feet from the side window of the case, with case fans at 60% speed which we have found to be just barely audible. With everything turned off and the room completely silent the meter registered a sound level of 39dB(A).

Once again we tested twice, once with the fan in "high" and again in "low." On high, there is no arguing, it is a loud cooler. There is the sound of a tremendous amount of air moving past the fins, as well as a fluctuating whine, not unlike a vacuum cleaner. It's not horrible, but you would not want it on your desk where you could see the Frag Harder Disco Lights.

On low the sound profile is quite unremarkable, with just the sound of the air passing through the fins. It is not the quietest cooler we have seen, but it is not unpleasant at all, just a very gentile white noise.
