@amigadave: I don't know how to take temperature readings. I didn't modify cooling, and didn't notice any problems for now. However, I still have unregistered MorphOS so can't use it for more than 30 minutes without reseting, so I didn't really stress test it under MorphOS. However, I played Quake III, RTCW, some youtube videos for 30 minutes each and didn't have any problems so far. Cooler tends to become loud under load, but I think it was like that even before overclock.
