Chosen Solution
Hello everyone, I’ve been having some sensors on my logic board not working at full capacity and also I feel the processor is overheating and that’s why fans running at 6100 rpm. I thought I would clean some of the dust so I opened up the heat sink and this is what I saw. You think the compound spilling like this is normal? It’s almost touching the pins.
Given the age of the system it does make sense to refresh the thermal paste as part of the cleaning process. Clearly your logic board is quite dusty! So it was time. Use a soft paint brush to scrub lightly the surface of the logic board to loosen the dust and then use a can of can’ed air to blow the dust away. Use short blasts and don’t tilt the can to much as you don’t want the liquid to spray out. You’ll also need to dust out the heat sink fins and fans. As for refreshing the paste here is what I would use: Arctic Silver Thermal Paste and to properly clean the surfaces I would use Arctic Silver ArctiClean or I would use isopropyl alcohol 85% or better and then toluene to finish the task. Unlike Apples paste Arctic Silver is slightly conductive so its important to not be as messy as the assemblers of your system where. Here’s a good guide on how: How to Apply Thermal Paste
It’s slightly more than it should be but nothing serious, it seems thermal paste was still in good shape and giving proper thermal bridging.
