I dont even oc mine at all but this xp 3000 runs hot as shit (like 44 c under max load, 38 idle) so I slapped a volcano 12 on it, and got a better exhaust type hsf for the oven er 9800 pro (since I dont think my case gets great airflow, seeing as how its at like 38C in summer, and then 33C with side panel off in summer)
