Hi guys,

Just wanted to ask, is high vrm temperature dangerous for gpu and affect its life span? My core temperature reach 77 while gaming (witcher 3), HWinfo doesn't show my vrm temp, but i'm just a little bit worried that my vrm temp might be much hotter.. what would be the safe vrm temp for gpu to last longer? thanks.. sorry for bad english

I have palit gtx 970 jetstream, even GPU-Z doesn't show VRM temp. I found out on some forums site that not all GPU have VRM sensors on it, it looks like mine doesn't have vrm sensors on it. is there an estimation like if your core temp is 77 then your VRM temp should be more or less 80 or 90?..

I come up with this question becoz I saw on youtube the MSI gtx 970, he measured the VRM temp using some kind of laser gun (don't know how to call that). It reaches 94C just by playing for 15min the comments are, he should RMA it, Also I found out on some cases like the ASUS strix, core temp are on mid 60's and VRM temp is 100C. I'm just a little worried since im not able to monitor my VRM temp just to be sure that it's not reaching those high temps.

They say VRMs should be 5-10°C degrees cooler than your core, not sure if it's with heatsinks or not, i didn't find info on the palit VRM temps but the Asus one has the same VRM cooling system (1 medium heatsink) and there are reports of high VRM temps , i don't know if the components are exactly the same though, Asus has 6 phases vs 4 for you, but not sure it makes a big deiffrence

If your card has a temp sensor in the vrm which it likely does, hwinfo should capture it. Try that. I have a readout for my asus strix 970 and I'm usually in the 60-75c range depending on my fan curve... But the gpu is under water, the vrm just receive air only.

Edit: the VRM are usually 5-20C hotter than the core. Even though my GPU is under water, which maxes around 41C, the VRM can get upto 80C no problem if my fans are set to low. I typically keep them around 60-65C.

so let's say for example I got 77C on core temp.. then my VRM temp should be more or less 100C? isn't that a little bit too hot?

cooler than the core?? I thought VRM should be much hotter than the core??

My bad, i thinks it's the other way around actually, VRM temps arent usually linked to the core temp, some people say 80-95 is ok, some say VRM are still kinda safe with temps around 100/105 other even say 110+ are still fine.
IMO you should make what you can to reduce the temps to a safe level (under 85), maybe try to fit in tiny heatsinks in the vrm between the stock cooler and the PCB, maybeput an aftermarket air cooler that usually comes with these tiny VRMs, maybe assemble a bracket config (HG10, G10, accelero hybrid) and add in VRM heatsinks or a final solution would be to watercool your card.

TL:DR
try one way or another to cool the vrm using heatsinks

It's likely that your VRM are going to be around 70-90C depending how much power the card is pulling and your power limit. VRM are safe upto like 120C but don't quote me on that though...it was a report from like 4 years ago...
