Ive had two processors with two different fans on an Intel P4 retail of course. Both of the processors fans can only spin up to 2000 rpm....where it used to spin around 3000-3500. The temporature warning keeps going off too. Ive tried two different motherboards too..... Also I ended up with a bad stick of RAM all of the sudden!. Could this be my power supply???? Would it cause the CPU fan attached to the motherboard to spin so slow and kill the RAM from incorrect voltages going throughout the mobo?
