Need Help with GPU cooling.

[Right Side Gone]

So basically i Got a killer deal on two gtx 770s. Im building a system for my friend in a standard asus case. With the side panel off the GPU only hits 70c under full load with relatively quiet fans. With the side panel on its hitting 80c and getting pretty loud. When i take the panel off and put my hand near the heatsink i can feel little air being pushed out. While on my other card i can feel alot more air being pushed through the heatsink. Both cards were cleaned and thermal paste replaced. The case has no intake fan, one exhaust fan, and the psu on top of case facing downwards. Although the exhaust fan is doing most of the exhaust work. The specific card is the EVGA GTX 770 sc Acx cooler. The side panel does have holes for some airflow , so this is the reason im asking. Is there anything i can do to improve temps and quiet the fan down?

Clean the heatsinks, replace the thermal paste & pads.

Not to be rude but in the post i mentioned that i have already done that.

Right... I can be brain-dead sometimes. Sorry.

So this is your problem... You need more airflow, You only have 1 exhaust fan. Even tho you have the side panel off, that may HELP temperatures. But having air moving throughout the case is how those style of coolers.. actually cool.. Get more fans. Also those cards generally run hot to begin with.

Ah i see. I did have a 760 twin frozr back in the day in one of these types of cases and it only hit max like 67c. With panel on. Same airflow. So i kinda ruled that out. But you're probably right.

To get down to legit facts... It's all about Turbo boost.

 

Go download MSI afterburner, whn you run it you'll probably see a Temp limit gauge there. Which more then likely will be set at 80c.

Turbo boost... boosts your gpu automatically and limits itself at the temp limit.

 

If the gpu somehow gets hotter then 80c, it will downclock, de-volt etc to stay at 80c. That is why you're at 80c. Now if you want to keep it cooler, you can lower the temp limit yourself, and add more airflow to your case.

Hm that's definitely worth a shot. Ill see how it impacts performance. As for more airflow the inside of the case has a front intake mounting spot, but it doesnt look like it could even pull in air from the front. Not sure why its designed this way.
