How to apply a Sensor on the VRM

[Enzo1998]

Hello guys how can I apply a Sensor to see the temps of vrm on my X370F Strix??

Use HWiNFO64. It will likely have a few sensors labeled something like "Motherboard" or "VRM" that will tell you the VRM temperatures.

 

There's also the option of just shoving a thermocouple on them, the preferred method if you're intending to do crazy stuff with your VRMs like dry ice or LN2 overclocking.

You already have the ability to see it. VRM temps are classed as "Motherboard temperature" from my understanding, I could be wrong. If in doubt, your motherboard has a thermistor cable connection. Thermistors are temp sensors that are used for measuring surface temperatures so you'd stick it on to a VRM heatsink. It's in your motherboard manual, next time if in doubt check the manual. Mobo manuals almost always answer all your questions. Unless you're doing SERIOUS over clocking, not like bumping a ryzen chip up to 4.8 or 5.0 ghz but real serious stuff then you won't need to care about VRM temps esp. on a decent board like the X370 STRIX

I just have a 2 pin thermal sensor that I can put on the motherbord header, but I don't know how to place it to read properly the temps on the vrm.
I wanna do It because the motherbord don't have a his own VRM Sensor, so I don't know what is the temperature

Just stick it under the big heatsinks next to your CPU. That will do you good enough.

If you stick it under the heatsinks then the VRMs won't make contact with the heatsink lmao. You can't just stick a thermistor under a heatsink, that's impossible.

OP please read what I said in my previous post.

You can't put a thermistor cable under a heatsink, even if you did (like if it's one of the pad ones) you wouldn't be making any thermal conductivity between the VRM and the heatsink so you'll have a useless chunk of metal and a burned up VRM.

so I ned to put it on the Heatsink, and stop??

Yes but again it's COMPLETELY unnecessary, I don't know anyone that does this outside of competitive over clockers. You don't need one until you get to LN2/dry ice cooling. Again, your motherboards "System temperature" reads VRM temps. Only reason people use thermistors is because at a certain degree under 0 the computer stops reporting the temperature accurately.

Thank you for the Help and the explanation

Not on top of the VRMs, next to the VRMs, hopefully touching. There's plenty of space under the thermal pads that touch the VRMs.

I'm aware of this, I never mentioned "thermocouples" only "thermistors" so I'm not exactly sure what you're getting at. Plus the heat from the side of a VRM won't be the same the top of the surface where the heat is being pulled to. That exposed side could be getting more direct airflow which means better cooling. Since thermistors measure surface temps it'd be quite inaccurate without a proper setup which the OP does not need.
