Let the research begin. (GIVE ME FUEL, GIVE ME FIRE, GIVE ME THAT WHICH I DESIRE)

The CF-72s can be upgraded, but only in the same family, I.E. the 1.6Ghz P4m model will accept up to a 2.5Ghz p4m processor as long as it is a 478 pin .13micron 400mhz front side bus. The Pentium 3m models will take up to around a 1.2Ghz p3m.
So it depends on which processor the CF-48 is actually using and whether they are soldered in.
( I think before that is where you messed up on your speed on your previous swap. If you dropped a 533 MHZ CPU into a motherboard that only supported 400 MHZ speed it will work but will be underclocked)(this can help some on heat running underclocked, but unless your cooling is messed up the Pentium M series runs very cool to begin with and shouldn't really need it)
