get either thermalright xp90 or xp90c.
but if ur using prescott i doubt it can b around 30c after OC.
for that must go for watercooling oredi.

press delete key.
environment temp also affects the proc temp.
make sure casing airlflow is good.

nv OC b4 changing to a better thermal solution.
change ur intel fan to wit a better heatsink+fan.
wat rams r u using?
intel mobos usually got no options for OCing.

less than 100 u wont feel major temp diff.
just get AS5 for rm25 la.
at least 2-3 deg.

or can try papst or panaflo.
using 3 tonados,trust me, u need a fan controller!

try and tighten your rams timings and c how things go.

go n verify it a xtremesystems.
