Finally got in my new heatsink.  Drops the max temps to what used to be the idle temps on my CPU at it's old overclock.  Now, however my dual core P4 will work at 3.8ghz (lol, and out the window go those better cooling numbers).  Unfortunately the power supply starts to squeal at that load.  the 12 volt rail (which at lower overclocks hangs at 12.2 volts or more) drops to 11.6 volts under load...and that's without the GPU doing anything to suck up even more.  So...for the time being I dropped it back to 3.6ghz.  I guess I really will need to stick a second PSU in the case.
