VRM Area Thermals

VRM Area Thermals

Lately, it has been requested if we could list VRM temperatures. We could hook into sensors and start measuring. but the best way really is to look at the VRM area with a thermal camera. This way you can detect hot-spots and/or worrying stuff. We test:

• Normal conditions / default settings
• Overclocked processor at 4200 MHz All cores and 1.425~1.44 Volts

Default clock frequencies  all cores stressed
 

Above a thermal image of the VRM Area and corresponding temperatures - this is under full CPU load and measured after 5 to 10 minutes in default conditions. M1 and M4 is the VRM heatsink under it, the MOSFETs, M2. There's just nothing worrying to see here.

Overclock 4200 MHz / All cores stressed / 1.44V

Above a thermal image of the VRM Area and corresponding temperatures - this is under full CPU load and measured after 5 minutes in overclocked conditions. M1 is the VRM heatsink under it, the MOSFETs, M1 and the rest are the solid chokes and capacitors etc. The board definitely gets hotter, however, is not passing 80 degrees C.

I do need to mention that the stock Wraith cooler is blowing heaps of air over this area. Ergo the dynamic would look different with liquid cooling. But really, it is common sense that if you overclock that you at the very least account for sufficient airflow blowing over that VRM area.
