Ok quick question guys...do you think a 1090T/965BE ad a 5850 should be ok with a Black Ice Extreme 360, or should I add a 120mm XSPC RS120 to that loop?

The 965 will be running 4 ghz at around 1.475 and the 5850 will be running 900/1000 at stock volts. The fans will be GT 1850's.

Am looking for a 5 degree delta...any help will be great.
