Just repasted and remounted. Even got it in there like you wanted ATM! Running Aida64 and will update you on the temps after 10 minutes.
After 10 minutes of Aida64, Core 1- 83C, Core 2- 86C, Core 3- 84C, Core 4- 80C. Seems effeminately a bit better, that air flow should help. I did watch it this time, all the cores seems to stay around 77C spiking up and down 8 or so degrees. Could this be because of adaptive voltage?
Also ATM, above my PSU i have 4 open PCI slots. Do you think it would be beneficial to put an 80/70mm fan there? If so, which way should I put it? An intake so it draws in fresh air for my GPU or an exhaust to help pull cooler air from the front of my case?
