How can i measure the vrm's temperature ?

[Electronics Wizardy]

thermal camera? Thermal probe?

Most modern motherboards have temp hardware built in to the board, and you would use software to measure.

If it's an older mobo, then you have to use some kind of external monitor like a temp gun

[Jurrunio]

With a thermal probe. Motherboards can give you a reading but unless the VRM consists of powerstages with built-in thermistor, the sensor will be somewhere outside the VRM and there's no regulation on where which means the number is less accurate and unreliable when comparing different motherboards.

Unless the board runs bare mosfets, an infrared camera is useless.

True, but what about thos epinpoint temp guns that can be used with a very narrow band of coverage?

You can normally see the board area around the mostfetts which give you a good idea of the temps. 

 

Also really useful for finding the hotspots on a board that you should put a thermocouple in.

Can that peek through the atoms of whatever the heatsink's made of?

Board area can have quite a significant temperature gradient if the heatsink isnt really narrow

that is possible, if you point the IR gun towards the back of the PCB. Thickness of PCB is usually much lower than the lateral distance from mosfets to exposed PCB from the front.

Probably not, but if the mobo has heatsinks for the VRMs, then it's probably modern enough to have temp monitoring hardware built in, which could be read by software.

 

Just my observations on VVRM heatsinks, mobo features and whatnot. Since we don't know what mobo the OP wanted to check on, this is all academic anyway.

So I happen to have a thermal camera, lets look at it

 

This board is a evga 780i-sli(i think, probably not exactly right), has some pretty big vrm heatsinks

 

 

First one is the back, YOu can see how the vmrs are that hot(as expected, was turned on recently and no load. BUt man those chipsets ran hot.

 

Here is the top. The actual mosfetts are covered by the heatsink(and don't look at the temps of the heatsink itsself, its basically a mirror), the iductors are getting pretty warm. Can see a few warm chips on the left aswell, looks like a part of the vrm , can't read the number on them.

 

So not perfect mostfet temps, but gives you a good idea, ans shows you where the hotspots are

yeah but thermal cameras are too expensive

If your motherboard has temperature sensors "on board", you can use either HWInfo 64 or similar

 

But most of the time, if you have airflow in your case& do not go overboard with vcore and vsoc voltages, then you have nothing to worry about with half decent boards.

i  WILL buy a Asrock steel legend B450M

You don't happen to have a 790i do you?

 

I have a 680i, 780i, and a 790i, and the 790i just won't post. Tried a few cpus and ram configs, reset the bios. Kinda just want to play with the best of 775

You will be fine with six-eight core cpu-s. Not the best mobo I know of, but capable enough for most.

I'd still check prices on MSI B450 A-Pro MAX and Gaming Plus MAX though

I might, let me check real quick

 

-sadly I do not, I have a 780 and a 750, the 780 is still in service lol.

i am going with a r5 2600 will it be ok?

i mean in newegg none had any problem besides some problems with the POLYCROME SYNC

of course it will be okay. 2600 is six-core, will literally run with everything.
