jcool praz is right

this is a known fact and was discussed even during the x38/x48's days
that the cpl chip doesnt need to be cooled and theres no internal temp reading from them..

almost everybody who blew their board after replacing the tim on their pwms
was because they had too much contact with the cpl chip.
