Thermalright ARO-M14G Ryzen AM4 CPU Air Cooler Review

Thermalright is known for low cost CPU air coolers that will get a job done. Its new ARO-M14G is a bit different in form factor than what we are used to seeing from the company, but it claims to have built this heatsink specifically for AMD's Ryzen socket AM4 CPUs. It even goes as far as to suggest it is suitable for fanless operation.


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.

Cooling from the Thermalright ARO-M14G was good, but not groundbreaking. In the CPU only test it was very consistent, with a maximum temperature of 84.5C, and only a 2C swing during our hour long test from minimum to maximum temperatures.

In the combined test it did fair a little worse as expected, but again not to a large margin. During the hour test we recorded a maximum temperature of 94.9C, while reaching a maximum package wattage of 168.5w. Temperatures were not quite as stable during the combined, which is also fairly normal, with us seeing a 4.3C swing between the minimum and maximum temperature through our hour long test.

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).

Here is where the ARO-M14G becomes very impressive, being one of the quietest air coolers we have tested. At 100% fan speed set in the BIOS, the TY-147A fan ran at a reported 1,320 RPM in HwiNFO 64. During testing we honestly had to focus in order to be able to discern the sound of the cooler. There are no hums, buzzes, or rattles to be found anywhere, and just a gentile sound of air being pushed through the fins. Even at the 100% fan speed we do all our testing at, this cooler would not be unpleasant to have right next to you on a desk all day.
