Case Upgraded but only 8C Max GPU Temp Drop?

I've been having some high temperatures on my GPU (EVGA GTX 670 FTW 2GB), around 88-89c and sometimes 90c on BF3, so I upgraded from my old cramped HPE 300z (lol) case to a Cooler Master HAF 922 which has one 200mm fan in front (intake), one 200mm fan on top (exhaust), and one 120mm fan in rear (exhaust). I transferred everything into this new case and ran BF3 again and it had only an 8c lowering in temperature (80-81c, 82c max)!

Is this a normal gpu temp improvement from a huge case upgrade? I expected more, as I would like my GPU temps to be in the 70's MAX, if not lower. The case comes with a space for a 200mm side fan that it pretty much right on top of my GPU. I installed a temporary ~120mm (that was laying around, don't know for sure the size) fan in the side of the case (as intake) and it had very little affect on my gpu temp (maybe 1C).

I've heard of people's GPU's not going over 60's C on full load, while mine (with an awesome, roomy, and high airflow case) is at 82C max...? Is there anything I can do to lower the GPU temps more? Will a 200mm side fan do the trick? (keep in mind the ~120mm didn't do much)

I expected more from a $90 improvement...

No, that sounds about right. You probably have the stock nVidia cooler on it, which is geared more toward being quiet than performing. 80C is perfectly acceptable however, much better than what you had before. Anyways, GPU temps are more affected by side intake fans, not front intake and rear exhaust.

it depends more on the cooler and the 670 FTW is a reference like cooler that exahust hot air outside the case so on the temps side of the GPU, an aftermarket cooler like the ASUS DirectCUII or the Gigabyte Windforce blow away that type of cooling...

For a reference design cooler and a OC card, 80 Celsius is pretty good...

Agree with these guys, I also have that exact card ;) 

In your case (lol, couldn't help it), the temperature seems normal. My card hits around 75 max but I have a fan on the side of the case blowing onto the card and also 2 extra intake fans. Yes it's a Cosmos 2 Ultra case and it's flipping massive.

So don't stress! Maybe get a side fan if your case allows it.

Ok, thank you guys for answering so quickly. I keep seeing people on forums (when googling) that say that their gpu's never get above 68c on max load, which seems like bs but I noticed that a lot of people are saying that. Every now and then you will see a person talking about 80's C. It's to weird.

To expl0itfinder: I'm happy to hear that my case improvement dropped my gpu temps as much as it was supposed to:) .

To pezonator: I have a CM HAF 922 case and it has an option for a 200mm side fan. Should I get one? Would it really help? Is it worth the price (will it give enough effect for the $$?)? It would be right on top of my gpu.

To spawnkiller [sry, this forum wouldn't let me quote more than 2 people (weird..)]: Glad to hear my temps are pretty good for a reference design and OC card:) .

I'd say that is about right too, if you are that worried do a custom fan setting in Asus Tweak, MSI Afterburner or Sapphire Trixx etc.

When people are talking 68C max temps, the only explanation is that they aren't overclocking enough ;) 
And sure, the 200mm side fan is worth it. Plus it looks cool.

Ok, awesome then:) . Do you know where I can get a 200mm side fan for a CM HAF 922? Does it have to be the same brand? Can you get stock ones, or do you have to buy something else? I want it to be as quiet as the stock ones that are on my case now it possible. If it has to be something else, can you recommend one that isn't too expensive? Thanks.

How much do you want to spend? The average 200mm fan is ~$20

~$20 should be fine. I hate to spend that (as I hate spending money, lol who doesn't) but if it will lower my gpu temps I definitely will:) .

Just go for any 200mm fan, if it has a 3 speed setting, that's even better, so if it's too noisy you can turn it down. It will really help with those temps and will be good for the dynamics of the case because you will then have 2 fans going in and 2 fans going out.

Good luck!
