I'm now using coollit EVO A.L.C. Excellent cooler for the price.
Idle without side panel on is 28c, with side panel around 32-34c. After 20 mins of prime95 50C max temp. Thats the highest core by the way. Max load was 50, 46, 43, 43. Idle without side panel 24, 24, 26, 28. With side panel, 25, 26, 28, 32. Sometimes fluctuating to 34 but then straight back down to 32. Using coretemp and realtemp to monitor temps.
That's at stock speed. With an OC to 3.2 ghz and minimal voltage increase my temps are 6-8 higher on idle and about 10c higher at max load.
Will come in under 50 bucks too.
