I hv a Dell Latitude D600 with faulty thermal sensor that show constant 85celcius even just boot and the air that blown out were not even warm. The fan were always at fullspeed. It throttle down to the lowest speed(500mhz).

I did remove the heatsink n clean all dust

I did replace the thermal paste

i replace another processor to confirm that is not a faulty processor's thermal sensor

I tried to change power setting to 'Always On' and is still the same

I tried to overclock it using NHC but its still slow

Anyway that i can disable the temp throttle down?
I dont care if that overheat my laptop as if i have to use a laptop with 500mhz i rather try to cure it.
Btw this is an unused anymore,i just wanna try to fix/modify to make it fullspeed again.
Thanks for viewing
