Well, I took the cpu block off. Cleaned it off (I may have applied too much TIM the first time.) and reapplied less. I only have the Arctic Silver 5 at this time. Reassembled and was seeing almost identical temps. Took the block off again. Definitely did not have too much TMI this time. Cleaned off and reapplied again. Reassembled only to see similar temps again. The pump is working, so that is not the problem. Any other suggestions? Seems like a simple system that should just work. Can the block be defective?
Thanks for any insight.
