gpu thermal throttling without reason

[Mr_Teddy13]

So, when playing bf4 sometimes my gtx 970 starts to thermal throttle at 50°C. It downclocks itself to 899 mhz, this happens at least a few times a day and it takes no longer than 15 seconds. I have no idea why this is happening, I've overclocked it but that overclock was running stable for the past 2 months so I don't think that that is the problem.

 

All help is appreciated.

PS: sorry for my english

Turn your power limit to the max and use a fan profile like so.

 

[Mr_Teddy13]

Thanks for the reply but my templimit is already maxed out, and I want to keep the semi-passive design at idle of the gpu, but I will adjust the fancurve to make the fans start to spin from like 30°C or so. I hope it will help. Thanks!

What happens when you run the Unigine Heaven benchmark?(without V-Sync)

Go to Nvidia control panel, manage my 3D settings, find power management mode and select prefer maximum performance. If the clock stays steady with that setting on then you're looking at a different problem.

When I'm running benchmarks nothing happens, also nothing when playing csgo (I know, it isnt very intensive but still).

reinstall the driver and see if that helps

 

if nothing works, RMA the GPU

I have played some bf4 for a while now and nothing happenend, so i guess it has been solved.

But what is rma?

Returning the gpu for replacement or repairs.

What happens when you are running a PhysX intensive benchmark?

So the problem is back and I ran some fluidmark for the physx, it runs fine at the 1080 preset (55-60fps). It only crashes when I bump up the particles to 270000 at 1080p. Is that good or should I be worried?

I had the same problem... I an issue with the Physx engine I did a clean install of the drivers. But this time clear the drivers first using DDU (available at http://www.wagnardmobile.com/DDU) while in safemode and then do a Custom re-installation (not Express) and deselect all but the main display driver and check "Perform Clean Install." This worked for me and everything works perfectly now. Hope it helps.
