I've got a 1.0ghz Tbird running at 1.5ghz (150*10, 1.87 volts). It's been running seti@home (command-line version) for 7 hours at 41 degrees max. Using Toast, burn-in program, I'm seeing 44 degree peaks.
There are coolers that do better but the great thing is I'm using a $4.50 cooler. (OK it was a $4.50 cooler but I upgraded it with a 38CFM Delta fan). The cooler I'm using is a Galaxy GC21 which I picked up at <A HREF="http://www.nexfan.com" target="_new">http://www.nexfan.com</A> as sort of a backup up cooler. (The $4.50 is a promotional price. Normal price $15.00). I chose it because it has a rare clip which uses all six tabs on the socket instead of just two. The GC21 heatsink is identical to a Volcano 5 unit (except for the clip) and has Galaxy's own 27 CFM fan by default. That fan works well but the Delta ... In factory trim the GC21 is about 5 degrees warmer.
I recommend this cooler for anyone that is worried about breaking one the tabs on their CPU socket with their present cooler. Add a Delta fan for some pretty good overclocking.
