Tags: Thermal Compound CPUs Motherboards Last response: January 15, 2014 11:58 AM in CPUs Share LewRussell January 15, 2014 11:55:37 AM I'm going to be putting the same CPU and the same fan onto a new motherboard. Is there any need to clean the existing thermal paste off? or could I just keep it on?

If you take the fan off then put it back on while leaving the same paste you will get a lot of air bubbles and your temps will increase a fair amount... Just clean it off and put new thermal compound on it.
