Guys, that's too hot, you are shortening the life of your CPUs. Mine is overclocked 227 Mhz and runs at 49C FULL LOAD. The Tbirds can withstand up to 90C, but the recommended would be under 60C.
I would consider buying a better heatsink and having someone mount it for you. It is kind of dangerous to take a heatsink on and off a Tbird.
In the meantime, try running with the case off and record the temperature. If it is much lower, add some case fans.
