Feb 5, 2018 · A VRM consists of MOSFETs, chokes (inductors), capacitors, and a PWM controller (the ISL95866 you listed). I'm fairly confident the VRM temperature reading would be measuring the MOSFET temp. I doubt the controller would really heat up much, and the chokes shouldn't be particularly temperature sensitive given they're just passive coils.

Aug 30, 2020 · You're using a cooler that doesn't exhaust air directly onto the VRM heatsink as the stock Ryzen coolers do. One way to provide additional cooling to the VRM is to locate a fan blowing on the heatsink, frequently a dead-air region in many cases. But so long as your VRM is staying below 90C rendering I wouldn't consider it a priority.

May 8, 2018 · as for the VRM phases count it's a bit tricky. you start with counting the inductors - those are the black cubes around the CPU. on your MB it's 4 to the left and 2 above CPU socket. that means that it's either 4+2 or 3+3. the first number is for powering the CPU cores and the second for the rest like memory controller and iGPU.

Jan 10, 2020 · Hello I have recently overclocked my Ryzen 3 1200 to 3.8Ghz at 1.2875 V and I installed HWinfo to monitor my temperatures during a stress test (Aida64) My cpu temps are fine ( around 35C idle and 65C under load), but I wanted to check my VRM temperatures as well and I could not find VRM MOS...

Jun 25, 2020 · That depends on design of VRM area and cooling, but yes 53 C is pretty low. Also this value is most likely not the internal VRM temperature, but measured by an external sensor somewhere in the VRM area, so it won't reach values like from own VRM sensors.

Oct 3, 2020 · The VRM on my MSI x570 gaming + was getting just over 90c as per HW monitor and yeah the heatsink on it was mighty toasty. I realize this board has a shit VRM and the 3900x I have it it is close to its limits. I added a fan near it blowing on the heatsink and this dropped its temps by around 7C so its fine as far as I am concerned.

Mar 8, 2017 · VRM cleans and delivers power directly to the CPU. You will see it around the CPU area on your motherboard and includes the chokes (small square grey boxes) with heatsinks on top (some motherboards don't have VRM heatsinks) and capacitors will be around them. 40C is a good temp for that and some motherboard/CPU combinations it can reach up to ...

Aug 15, 2022 · HUB probably tests 'open air' like most review sites do. That allows for better air circulation around the VRM area which will naturally be better for cooling. 68C is nothing for a modern power MOS-FET. Check your VRM temp after an hour or so of maximum all-core CPU work, something like prime95.

Oct 1, 2020 · VRM/MOS FAN 12,000 RPM. I tried changing it in the MSI BIOS (latest version) and no matter what I clicked on, it stayed running at 12,000 RPM (MAX speeds). None of the setting options increased or decreased the the fan in MOS, Smart Fan mode changed nothing, All Full Speed changed nothing, Default change changed nothing.

Sep 15, 2013 · In speedfan, temp2 which I have determined is the VRM (it lowers considerably when blowing compressed air onto the VRM) will rise to upwards of 60 degrees under prime95 while temp1 which I assume is the CPU temperature (it is the next highest) will rise to upwards of 45 degrees under prime95.
