To-do: Replace the video card with an ASUS DCII 570 or maybe a 6950 if Nvida can’t sort out their TDR driver mess.
Replace the stock cooler with a Corsair H80 (stock Intel doing a fair job for now). Probably set to pull air in over the radiator and exhaust out the top.
I would avoid the H80, a tower cooler with good fan should be good enough, since you already going with lots of slipstreams, and if you like them, i would go with Scythe Mugen 3
, also comes with one slipstream PWM.
Btw just wondering, there were issues with another GeneZ user and slipstreams using Case Fan Headers, he couldn't lower then below 1000RPM, i know the bios restricts the case fan headers to 60%, but this shoudl be around 780rpms, but i seen other use AI SUITE / Fan Xpert and lower below that... but just wondering since you have full PWM Slipstreams what speeds is your setup allowing.
