GPU fan speed increases automatically whenever I play games

Note: I made some recent upgrades to my computer. I transferred all my hardware into my new chassis - the Fractal Define R4 Black Pearl and installed a new Corsair CMPSU 650 TX power supply.
-----------------------------------------------------------------------------------------------------------------------
Before I play any one of my games, I use MSI Afterburner to turn up my 7970's fan speed (around 40%) to balance cooling with noise.

Recently, my fan has been exceeding the limits I set for it as the GPU fan's noise level gets out of control whenever i try to play my games. I would set the fan speed at around 35 ~ 40%, then when I start the game I hear my card getting increasingly louder, probably around 50%.

How do I make it so that I can force my card's fan to stay at one speed rate?

well doc and Ellis said that this would happen, when your gpu needs more coolin dont be a foolin.....with fan caps.

I regularly check my temps, and 35~40% fan speed stabilizes my gpu temperatures at around 70 ~ 90C.

I repeat, is there a way for me to stop my fan's erratic behavior?

Not really :/ 

Your GPU is taking measures because you've gone over ~80c I reckon. So you can have whatever limit you want but the GPU is probably sensing the heat and overriding your feeble mortal controls and cooling itself so that, you know, it doesn't break.

I'd probably suggest alternative cooling measures inside the case itself if you wanted to handle the situation that way.

Either that or give me the actual GPU brand name and everything and I'll see what I can do to help you bypass the obviously beneficial emergency temperature controls.

Brand name GPU is MSI R7970-2PMD3GD5

Well I checked it out and it seems that you should be able to turn off automatic fan control and manually set the fan speed.

My guess is that your card has a fail safe to protect itself from burning up(which is a good thing)

So your option is to apply a more aggressive cooling solution for the card to keep it from going past 80c or to adjust your fan/airflow/wind tunnel situation inside your case or to put up with the noisy noise for which those cards are just so well known for ;) 

You could, if you love living on the edge and wrecking perfectly good gear, try to hack the fan controller and the fail safes. I am not going to tell you how to do that for my assumption is you'll burn your card in a few sessions so hopefully someone else will let you know how to hack the controller.

You have it set on Auto...so with increased it heat/load fan speed increases...

What kind of upgrades??...and to the OP sounds like GPU wants to run on the hotter side.....have you ever reapplied good thermal paste?

Whoops I made a mistake.

It wasnt the GPU fan that was increasing but the CPU. My GPU was obeying me all this time, it was the CPU that decided to get all loud and cool temps. Nothing I can/want to do about that.

Thanks for the answers though.

Well hold on now, we can totally help you with CPU cooling ;) 

Get yourself a Noctua if it will fit, those things are near silent and do the job nicely.

You'll always hear a bit of a hum but soon as the gaming starts you wont hear a thing :D
