You might want to put a Zalman Copper/Aluminum Heat Sink with the 
special large adjustable rate fan.  Zalman has a kit.  I put it in mine 
and it has kept the heat down.  Unfortunately, I don't have number for 
you but I do know that the guys at Ginstar who helped me install it were 
impressed with the performance and reduction in sound level.  You could 
just replace the thermal compound and retry.  Of course, if you don't 
have a good bond you would probably just melt the CPU.

Putting in lots of fans is okay but the path of the heat evacuation has 
to be thought thru.  You really need to not be recirculating hot air 
around the CPU.  I had some problems with this until I switched to a 
power supply that had a fan pulling in air from the CPU and another 
pushing that same air out of the case.  Too many fans can actually 
create whirpool eddies in the case that just recirc hot air.
