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.

Thermalright ARO-M14G

Taiwan based Thermalright has been helping keep PCs cool since 2001, and over the years have brought us some of our favorite coolers, and always at a great price. It has been 16 years since we reviewed our first Thermalright HSF, coincidentally, that HSF was designed specifically for AMD CPUs as well.

Today we are reviewing the ARO-M14G, an AM4-specific cooler for Ryzen and Ryzen 2 CPUs. Featuring an enlarged copper base to ensure full coverage of the Ryzen IHS, as well as "Proprietary through holes on fins for efficient ventilation." How will it stack up on our highly overvolted Ryzen test rig?

System Setup

Today's review takes place on our purpose built cooler testing system, featuring an AMD Ryzen R7 1700 overclocked to 3.9GHz, a GIGABYTE Aorus AX370-Gaming 5 motherboard, 16GB of Corsair DDR4 memory, and an ASUS GeForce GTX 670 DirectCU II TOP GPU. Full details of the test system and testing methodology can be found here.

Test Methods

CPU

Our AMD Ryzen 1700 CPU will be running at 3.9GHz across all cores and will be being stressed by Prime95 using Small FFTs in both our CPU only test, as well as our combined testing. Our CPU Package power measures ~170 watts under full load.

GPU

In combined testing our GTX 670 will be running Furmark in addition to Prime95. This puts an additional 250 watts of heat into the system that the cooler will have to contend with.

Case

Testing is being performed in our Obsidian Series 750D Airflow Edition Full Tower ATX Case. Chassis fans include two Corsair 120mm fans pulling intake duty in the front, and a Corsair 140mm fan exhausting in the rear.

Fans are set to a locked 60% speed during all testing, as we found that is the best balance between performance and noise.

Thermal Paste

Thermal compound being used is Promilatech PK-3 Nano Aluminum. This is a very viscous compound rated at 11.2 W/m and requires no burn in or setup time.

Temperatures

Ambient temperature will be kept at as consistent temperature as possible for the duration of the tests. Temperatures are being measured in 4 places during both tests using our Sperry DT-506 Quad Input Thermometer, case intake, cooler/radiator intake, cooler/radiator exhaust, and case exhaust.

Idle

Average idle temperatures will be recorded after a thirty minute period of system inactivity.

Load

Load temperatures are measured every 5 minutes from all four points with the Sperry DT-506 thermometer, as well as the CPU Temperature (Tdie) and Package Wattage as reported in HwiNFO 64. Both the CPU only as well as the combined tests are 1 hour long, at which point the average temperatures will be used as our data point.

Sound

Sound levels will be measured with a BAFX Products BAFX3370 Digital Sound Level Meter from a distance of four feet away from the side of the case. With everything turned off and the room completely "silent," the meter registered a sound level of 39dB(A).
