Thermal Image Testing on AMD X370 Motherboards by ASUS, Gigabyte and MSI

ASUS ROG Crosshair VI Hero Thermal Image

When running the ASUS ROG Crosshair VI Hero motherboard ($254.99) with the AMD Ryzen 7 1700 processor and Corsair Vengeance LPX 64GB (4x16GB) memory kit we weren’t sure what would be the hottest area of the motherboard as it has an impressive 12-phase VRM configuration.

ASUS Digital PWM Design

Here is what ASUS has to say about the digital power controller design on this board:

“The Finest Power, Digitally Controlled

ROG’s revered digital power controller now delivers even-finer power, with Texas Instruments NexFET MOSFETs, MicroFine alloy chokes, Digi+ PWM controller and 10K black metallic capacitors — ensuring Extreme Engine Digi+ always delivers the smoothest core voltages.” – ASUS ROG Crosshair VI Hero Landing Page

ASUS ROG Crosshair VI Hero VRM Phase Temperature

After doing a 10 minute stability test with AIDA64 we noticed that the highest surface temperature on the CPU VRM phases was the capacitors at 42C, but that wasn’t the hottest part of the board.

ASUS ASUS ROG Crosshair VI Hero Memory VRM

The hottest part of the board was actually the two phase memory VRM and we were getting temperatures in excess of 52C, which was 10C hotter than the CPU power phases! During this time the motherboard temperature sensor was reading 23C, the M.2 PCIe NVMe SSD was sitting at 31C and the AMD Ryzen 7 1700 processor running at stock settings was at just 43C. So, the hottest spot on this platform wasn’t the processor, X370 chipset or the CPU VRM, but rather the memory VRM!

    el chipset?

    That thermal imaging on the msi titanium failed so miserably. You don’t need to get easy on MSI, we know it sucks, and the memory VRM is the only strong chain with that boards VRM.

    Good stuff. Very insightful! If you can please also do test with overclock. After all these boards are geared towards the oc/gaming community! Keep it up!

  • Hi Nate. I have a suggestion. You did this test with Corsair with Corsair H110i which has no direct airflow to the motherboard. Perhaps you can do some tests with Wraith Spire? Wraith Spire should provide some airflow to other components around the CPU socket. So, perhaps the temperature can be lower on other components, except the CPU itself.

    Nice work. Now, I need to get some air on my memory VRMs on my Gigabyte/Aorus AX370-Gaming 5. Funny thing, on HWBOT.org, in the Ryzen Rookie Rumble: I am currently in 1st place in the Memory clocking challenge. I merely have my memory set to the XMP setting @2933 mhz. No real overclocks there, other than what the memory is advertised to be able to run at.

    Good one Nathan.
    Be nice to see thermal imaging done on all SSD’s during reviews especially
    M2-NVME…………………………..

    Sorry i dont understand englisch so good. Which is the best board? Thank u very much for this cery interessting stuff.

  • Illusio13

    Good dudes; love to see these type of articles; very informative and shows at stock no problems but gives us a better idea if overclocking.

    Moar please!
