GPU getting hotter (60 degrees to 80 degrees), possible sensor problem?

[SilverMight]

So, I'm used to my GPU running at a good 60 degrees celsius at max load. A few benchmarks also show that my GPU, the ASUS Strix ROG GTX 1060 runs at a cool 60 degrees centigrade at load. However, within the past month, it's been getting up to the 70's. I wasn't worried about it at first since the max recommended was 90 degrees; however today I launched MSI Afterburner while playing Rust to see that my GPU was apparently running at 82 degrees celsius, which was alarming to me. I turned the GPU fan speed to 80%, which started to cool down to 70. After 30 seconds, I set it back to auto. Then it was running at 70 degrees centigrade again.

Any reason why this was happening? Maybe a bad temperature sensor? It's been running at 70 degrees now for 10 minutes.

sounds like bad air flow in your case honestly...

when did you buy it?

if ambient temps in the space the PC occupies increased, then that could explain the sudden rise in temps

if they've been constant, and you're not comfortable with the high temps, a repaste might help, but asus stuff is decent from the factory

I'm just using the 200mm fan included on the case. Should I open the side panel and see if anything changes?

I'm less concerned about it being 70 degrees - I'm assuming that's just spring at work, but why would it show 80 degrees? It's never gotten that hot.

could be a strange temp reading by afterburner

Dust in heatsink? Even though it's not a blower type cooler, dust still builds up in the heatsink.

Possibly, I'm getting some air duster soon

What's your idle temp?

That should really be one of the first things you check when GPU temps don't seem right, it is for me at least. You probably don't even need compressed air to clean it, with those types of coolers you can usually just remove the fans with a couple screws and brush of the layer of dust that builds up on top of the heatsink with a soft paintbrush.

Found a fix - just replaced my CPU fan from the stock cooler to a Cryorig H7, cools much better and causes the case temperature to be much cooler. In the end, the GPU is much cooler now.
