The 9750 I did right, more or less, with Ceramique paste and a Zalman 9300 (I think). I don't think it's oc'd. if it is, not by a lot.
With the1090 I got lazy and used the tape and stock hs. But it looks like it is begging to be oc'd and very forgiving of mistakes. The board (MSI 790Fx-GD70) is also very nice to work with. Right now it is at 3600mhz. Memory had to be over volted to get it to run at 1600.
So if I go with the window a/c unit, then i'll probably dig out one of my xigmatek's and use that.
