Thanks to Dirk for pointing me to the thermal compound discussion. I did a little research and found that Arctic 5 had a good Watts per mK heat dissipation. There were others and I finally decided on Nocterna NT H1 paste. I talked to the computer tech where I purchased the stuff and after describing the dryness of the OEM paste he thought that it was becoming ineffective. The compound is effective for about 3 years then it should be replaced. The next issue I had was how much do you put on. I looked at the photo of the OEM job and there was a more that what was needed. The solution was to apply a decent layer on the heat sink contact area. Putting it elsewhere would be ineffective. I did a trial application and when I separated it you could see that there was a complete contact area. And yet still no were near what the OEM amounts were, ( it looks like they overdid it) For good measure I added a small amount to make sure that it was making ideal contact. I think it’s important to pay a good price for such an important part of the controls. This made me think of others who pump up the RPM to make the aircraft into a super sport. Maybe this extra speed will exceed the heat sinks ability to keep the components cool. I’m no expert, Just my two cents.
