Thermalright Ultra 120 Extreme


Mar 17, 2009
What fan should i put on the TRUE? I have to add a fan, as it doesn't come with one.
So, i have 2 questions:

what is the best fan for performance & price (120mm)?


what thermal paste should i use between CPU and cooler?

btw, going to use:
i7 OCed to 3.8
gigabyte ex58 ud4
nzxt tempest
I'm using a single S-Flex SSF21-F. I chose the "F" as a good compromise between airflow and noise. newegg sell "D" through "G" models.

My temps in an Antec 900 case, fans set to LOW were:
Q6600 and Q9550 idling around 30 - 35 C.
Q6600 OC'd to 3.6 GHz. load temps 61C - 65 C.
Q9550 OC'd to 3.6 GHz. load temps 58C - 61 C.
