Does GPU temp have any indication on VRM temps?

post #1 of 9
Thread Starter 
I've heard theres literally no cooling for VRM on reference 500 series. To those lucky enough to be able to have VRM temps shown in windows. Is it enough to say VRM temps are usually around the same as GPU temps or are they totally different? I would think that they would be the same or close since the temps are very close together, but I'm probably wrong.

My card maxes around 63c load with my fan profile and it seems like it could take more voltage, but I don't want to risk it without knowing the answer to my question first.

as long as you keep the gpu temp low the vrms should stay low also

No, the two temps are frequently very different. You can try using different monitoring programs to check the temps.

Hmm, but how close are these two temps? Are we talking ~5c difference or 20c, this is pretty much my question.

Wish I could, but Nvidia decided to remove VRM temp monitoring on the reference models.

They are supposed to be within 10 c or so of gpu is what ive heard, but I dont see how you can tell, especially if the heatsink covering chip and vrm isnt shared, many card having no vrm heatsink.

This is why vrm heatsink should be required by default for any mid to high end card for both amd and nvidia. I just cant understand why they wouldnt pay the extra few bucks for it. It would save money in long run.

Lots of people are concerned with vrm temps, and for good reason. When you runs cards at or near 100 percent for 6 hours plus, you better believe the VRMs get mega hot with no heatsink.

Do you have any VRM cooling for those 480s? What voltage do you run them at?

temp monitoring software doesnt take into account the VRMs. What I do is just give them a little bit of a groping and if they dont give you a first degree burn then they well within safe temps.

run them now at 1137v i have some ram sinks on them and a fan which blows through both cards

keep them really cool.


when i had them on air it was too hot the case was on fire.
