WELL FIRST OFF WHAT ARE YOU USING TO CHECK THAT TEMP?? oops caps sry secondly is ur board new or a second hand purchase?? if its a newer board you should have the fixed nb sink if its second hand well theres a 50/50 chance it has the older style. I understand the fix it moderatly easy to do. its simply a matter of filing the standoffs down a tad. Have you even removed it to see if its tp is applied correctly???
