I got mine to freq 250. Took out the intake fan and used a fan I had laying around.. I replaced the thermal paste for all the chips and only had enough left over for one of the heat sink in the back. You can see the temp difference of replacing the thermal paste. I used Antec F7 since I didn't want to wait for the MX-4 to arrive in the mail. The room is about 23.3C and the fan rarely goes above 1700.
