GTX 690 High Temperatures

www.techpowerup.com/.../32.html

Says your temps are pretty high unless you are doing some extreme over clocking.

CPU Radiator Fan = Out

AMD 5870 = Out

Memory fan = Not sure but it's tiny and worthless

PCIe = In (the front)

HDD = In (or at least front to back)

... so it's mostly like this already. What's missing it a nice exhaust fan on inner top.

The Aurora is a small case and unlike your GTX 680's that dump the hot air out the back the GTX 690 dumps its heat into that case. It then gets sucked right back into the GTX 690 so it ends up trying to cool itself with hotter then normal air.

I wonder if they should snap away the inner shroud, let the hot air rise inside the case, and maybe add a small exhaust fan to the inner top ? Hopefully, the front inner PCIe fan will be still able to do it's job.

All the new fans I installed use 4 pin connectors, they are not controllable *** thats fine you cant hear them at all (especially because my gtx 480 is so loud!). Im thinking about raising my case on feet and cutting a bottom hole for a screened 120mm fan. My final setup will hopefully have an airflow system like this (rough drawing I know):         I know it looks overly complicated and convoluted but I find that the large number of intakes will provide enough incoming air so that all of the exhausting fans and components can take in a sufficient amount without leaching too much from another part. Also notice that the roof exhausts will bend the path of the air so that it runs over a larger surface area instead of just going in and out in a straight path (the bottom intake will also do this to a degree). Keep in mind this mod is 75 percent form 25 percent function as my pc is already decently cooled.

Maybe this^ or what about doing push/pull on the CPU cooler for a better exhaust? Does the Aurora CPU bring the air in or out? If in I would maybe try reversing it and doing the push/pull.

Make sure the GPU fan is running and nothing is blocking it. Heat is always an issue with those cards.

You do have options to help alleviate the extra heat.  You can add extra exhaust fans to the case to help get that hot air out. Bumping the PCI fan to 40% like you did should also help. I would also bump the GPU fan up or make a custom fan curve for it. Download something like MSI Afterburner to do it if you do't have any software for it.

@Morblore Yea I even removed the gpu shroud to make more space for the airflow. And also I already had set up a custom fan curve with MSI. I have the fan spin set at 15% higher than the temp reading, the fan speed pretty much almost goes all the way to 100%. I also never thought of the whole concept of the gpu resucking the hot air back in. Does the aurora have more space to add exhaust fans?

Tesla that's exactly what I was thinking. I should be able to add an exhaust fan on top right?
