That S5 was running in the low 60's at 3960 RPM - After the thermal compound it dropped to 50 at 3240 with the same room temperature. Lower HW errors too. I'll pull the next worst one tonight and repaste it for comparison. The Gelid stuff is really stiff and gluey compared to the Arctic Silver compound. That's probably a good thing

If I were completely ADHD I'd sort the boards across units and get matched sets lol.
Impressive results! What is your ambient temperature? Please share more details on exactly how you applied new compound. Thank you.
This is the stuff I used:
http://www.ebay.com/itm/331178553288?After cleaning off the chips and heat sink, I put a drop on each of the BM1384 ASIC chips and spread it lightly with the flat applicator that is in each package. The springs and shoulder hardware keep the board from being overtightened and squeezing out the compound from between the ASIC and heat sink, so the procedure is fairly simple. Of course, an ESD mat an wrist strap is recommended !
