I'm quite pissed off as I spent extra on picking the low noise components to get a quiet system but I have to run the fans on everything at high RPM to keep things just within temp limits. I know over clocking produces heat, but things are much hotter even at stock settings. An open case makes 2-3 degrees difference but not much more. I've even had the case open with a pedestal fan blowing straight into the open chassis. It's winter here at the moment so I hate to think what it will be like come summer.
Have you considered water cooling ? System looks awesome and your temps will be down by 20 - 30 degrees under load.

I'm really happy overall with the system except for the heat and noise. Loaded up Battlefield 3 last night with the graphics set on ultra and adaptive vsync enabled. It didn't drop below 60fps once at 1920x1200 with GPU temps in the 50s.

I have been considering water cooling for both GPU and CPU (won't discuss CPU in this thread anymore) but was trying to avoid extra cost, complexity and space. I'm considering replacing the TIM on the on the GPU using Arctic Silver 5. Any hints, suggestions or things to be aware of in doing so would be great.

I'm assuming that removing the heatsink is just a matter or undoing the four screws on the back of the board and gently lifting it off. Doing some reasearch I understand there are some thermal pads on the base of the windforce heatsink (see below) . Do these need to be replaced with fresh pads, if so where do I get them? As AS5 is a electrically conductive material, are there any special precaustions required?

I don't really like AS5. Also has a long cure time. I use mx2 or mx4 a lot on gpu's. THe thermal pads should be ok if they don't get really wrinkled up. You can buy them at a watercooling site like sidewinder. But you should be able to reuse the stock ones.

50c sounds good to me but honestly as5 isn't the best out there. It's easy to apply but I used it once about a year ago on a build and going to shin etsu x23 lowered temps about 2-3c. Lights out is right they say it takes like 200 heat cycles to get full performance out of it.

Was there a specific reason you wanted lower temps since your already in the 50s

hmmm....i bumped up my core clock to 1095 and the max observed went to 1228 but have yet to do a stability test on it.

My temps were in the high 70s when running Unigine Heaven DX11 Benchmark and Furmark with the settings to test stability as per the GTX 670 Overclocking Master-Guide. My understanding is the aim is to have the temps below 69 when running both these tests, hence why I'm concerned that it is running hot. Given that the benchmarks are meant to stress the card above normal use to ensure stability and the in game temps are quite good, I could be worried about nothing. I haven't had the opportunity to test the card outside of these benchmarks so I don't know what the performance is like for my typical use.

I grabbed AS5 as this has been easier to get my hands on locally than the MX-4 and I was initially only going to use it just for my CPU.

I would look into what gigabyte uses because as5 can be worse. For instance Asus uses shin etsu which is one of the top ones out already, so if you used as5 on that your temps would get slightly warmer.

Your case looks like air flow isn't its strong suit. That may just be your probl;em. Tried running with the side panel off.

I will say though compared to the gigabyte I had and what I see others post. If airflow is not an issue it seems like there may be some type of mount issue. Maybe the heatsink is not secured or maybe they did put way too much Tim. Have you opened it up yet?

I don't think my card ever broke 60c.

Btw did you run heaven and furmark at the same time? From the way you worded it I wasn't sure if thats what you meant. Also was that at stock. FIrst thing I would try is side panel off, even put a desk fan right at it just to be sure air flow is not your issue.

Good call. Yeah I know the tj08-e can hurt temps a bit, so this case if not equiped with extra fans I bet can cause some issues. Wonder is thats what he did is run both at the same time? I think on heaven im A HAIR warmer than on bf3 but he has much warmer temps so maybe he was doing both?

But overall 50c gaming is good. Im in the 60's in 80+F ambient temps. So long as your at 69C or less I wouldnt worry.

Well he had Vsync on when he was playing BF3 so that doesn't really help to compare the two. But he says he was in the 50's gaming and high 70's benching. Something seems weird there. Not sure whats what.
