HW Monitor gives me the same readings as RealTemp, although it's a bit slower.
If you're hitting 85-90ºC chances are real good that you don't have adequate cooling.
Let's hope that the OCZ Freeze has a good break-in period.
I've got an Antec 900 and XIGMATEK Dark Knight and I know I put it all on right. THat sounds like adaquate cooling.
So either the 6 Drives and tons of PCI Cards and clogging up my case too much, or I just got a cheap i7.
