Gpu heat problem

I seem to have some heat problems on more graphically intense games. I can play Skyrim on max settings with my gpu ranging from 60-75c, however whenever I load up Metro 2033 or Witcher 2 my gpu temp seems to climb to 85c sometimes higher which can sometimes cause the game to freeze and on one or two occasions cause my computer to restart. I have my fan speed set to 55% using MSI Afterburner. Would adding one or two more fans to my case resolve this issue or not? I already have one fan at the back of my case and two on the top. My idle temp ranges from 20c-27c.

Here are my specs:

CPU: i5 3570k
GPU: MSI Twin Frozr 7850
Motherboard: MSI Z77A-G43
RAM: 16gb (can't remember the make)
PSU: 750W OCZ Fatal1ty
Case: Cooler Master CM 690 II

Obviously, 55%.

This is the fan curve that I use: (Picture taken from OCN)

Works really well. If you find the noise annoying, you can always tweak it. The idea is to keep the GPU under 70C which is when the card starts to throttle down the clock which is a performance decrease.

Why set the fan to fixed 55%?
Use Afterburner to create a custom fan speed curve to allow it cool the card more. Surely you can live with a little more noise when gaming?

Adding another fan to increase case airflow will have insignificant effect on GPU temp.

Thanks for that I'll try setting my own fan profile and see how it goes, i'll reply back with my results.

Not sure if this is sarcasm or just lack of comprehension lol.
He means, how fast in RPM are the fans spinning? Also, I don't know about your personal tolerance for noise, but every twin frozr equipped card I've ever heard was perfectly tolerable at 80-100% fan speed, so I don't know why you don't have that thing set to at least 75% when temps hit over 55-60c. These coolers are nowhere near as loud as reference blower coolers, so it's not like you're gonna be hearing a hairblower go off every time your gpu warms up....

-EDIT-
Damn, I can't read either. I missed the fact that this wasn't OP but w/e, advice still stands. Unless the case has terrible airflow, no need to be letting your card hit upwards of 80C when it has a perfectly capable cooler.

I would say the optimal temperature is actually around 75 degrees. Personally, my card regularly exceeds 80 degrees with no decreases to the core or boost clock at all.

Just tried playing Wither 2 then. I changed my fan profile to the same as Colli's. I was only playing it for about 5-10 minutes max and the same thing happened again, gpu heat kept climbing, however this time it was at a slower rate, it was ranging between 75-78c at 90% fan speed but then the heat just suddenly started climbing where it hit 83c at 100% fan speed and 99% usage, started getting graphical tears in game and my monitor went black for a second and then came back on to the game. Exited the game and checked my fan rpm which was at 5067 max. Does this mean there is a problem with my card?

I don't see what all the fuss is about but kiddies these days are thick headed. 70c+ isn't bad but just keep this in mind that even if the core is well within it's limits the rest of the card can still overheat especially the power vrm and if that fails all that you will have is a brick. It is best to try to keep the card in the 60s and then it will outlast it's usefulness.

I know that it isn't a bad temperature but it is not really an ideal one if it is still going past the 83c mark. What's the best way to bring down my gpu temp then? Add more fans or should I sort my cables out some more to allow better airflow?

Well, yes, obviousy. If your case is a mess of cables, fix that up. If you have room for a bottom mounted intake fan, use it. If you can mount a side panel fan, do so, and set it up as exhaust to help move the warm air away from the card and cpu. Unless you got the short end of the stick and your card is in fact faulty, there is NO reason for it to be hitting over 70s temps; it's an HD 7850, not a 7970 :\

Even the 7850 can run hot. You need to think more in terms of usage. Where a 7970 may only be utilising 50-60% of the GPU, the 7850 may be using more like 90-100%. This means that the 7850 is working harder, therefore resulting in more heat. Just because its a less powerful card doesnt mean it doesnt work as hard...

I do however, agree with what you said about bottom and side mounted fans. When I installed a high flow fan on the bottom of my case, it decreased my bottom GPU temps by about 7-8 degrees.

I've got room for one fan on the side panel since my cpu cooler blocks the other free slot, and also have space for one on the bottom so I'll try that and see what happens. I'm hoping it's not faulty since I had to rma it a few weeks after I originally got it last year because of a fault.
