Most likely your first thing to do is find out what type of fans you have and how much air they're moving. Are they quality fans or cheap knock-offs? See if you can find specs on them as far as voltage, airflow, etc. Then look at the overall configuration inside the case and see if there is anywhere or anything you can do within reason to make the airflow better through the entire case (path). Are there wires all over the inside blocking the airflow Can more or better quality fans be installed to push air through the system more rapidly and efficiently?The case has a lot of room and the cables are neat and out of the way. The problem is the fan exhaust is covered by to much case material and the input case fans are also covered byt too much of the case preventing unobstruced air flow. I hate to tear this case up considering $6 grand was spent on the PC.
This is why I am going to phase change or water cool the PC as soon as I get the drivers stable. I am tending toward water to avoid condensation issues.
I would also suggest that since it's an EVGA mobo, you go to their website in the support area and see if they have a forum like Asus does. There you can post about what issues you're having with people who are using the same mobo and possibly a similar setup. The Nvidia drivers are another issue.
Agreeded and yes I have read for the better part of a week on that site. In fact that is where I was pointed toward using driver sweeper to get rid of left overs. It appears that many folks have had this identical issue with drivers.
"Two NVIDIA 9800 GX2 GPU's (from DELL) in quad SLI", you mean dual SLI?
Nvidia drivers can be a royal PITA and the best thing to do is find a driver that works and stick with it. Some of their supposed upgrade drivers aren't the best researched ones and can create more problems than they're meant to fix. The latest, isn't always the greatest.
