I wouldnt do it
You could go into power management and decrease the max processor frequency by
just a little bit (90-95% setting)
by not letting it go all out to %100 percent you wouldnt lose any noticeable
performance and would drop temps
Mmm cool idea king smp, i'm tempted to do it just out of curiosity... Will keep you posted =D
Also, what program would you recommend for testing CPU processing power?
Ill compare my stock T7500 against the stock T9500, then tinker around and see what i can do with the T9500.
I think ill also check temps of gpu and cpu under load as its for a laptop which shares one heat sink for both CPU and GPU.
