GPU VRM safe temperatures

125C is where MOSFETs top out, if you could still touch the heatsink without getting burned you are probably fine, the twin turbo should blow a bit of air over them as it draws air down onto the PCB too so its not like there is 0 airflow either

Hello everyone, i have a gtx 970, a zotac dual fan model. I recently chnaged the stock cooler for an arctic accelero twin turbo II, i saw a 20c degree drop on full load temps. One thing that worries me, is that te cooler fans don't blow aire over the VRMs, because of their placement on the board. This GPU doesn't have a sensor on the VRMs, but i touched the heatsinks that you glue onto them, and they were hot, not to the point that i had to remove the finger instinctively, but hot. I can't measure the exact temperature, but my main concern is, should i worry? We are in summer here, so ambient temps are like 30 to 42 degrees celsius.

I spent $2500 on building my PC and all i do with it is play no games atm & watch anime at 1080p(finally) watch YT and write essays...  nothing, it just sits there collecting dust...

Builds:

The Toaster Project! Northern Bee!

 

The original LAN PC build log! (Old, dead and replaced by The Toaster Project & 5.0)

"Here is some advice that might have gotten lost somewhere along the way in your life. 

 

#1. Treat others as you would like to be treated.

#2. It's best to keep your mouth shut; and appear to be stupid, rather than open it and remove all doubt.

#3. There is nothing "wrong" with being wrong. Learning from a mistake can be more valuable than not making one in the first place.

 

Follow these simple rules in life, and I promise you, things magically get easier. " - MageTank 31-10-2016

Completely normal. If it isn’t artifacting or crashing, you’re fine. Run the fans harder if it’s a concern.
