What is the Best Thermal Paste for a Mac Pro Upgrade?

Question

I am looking to better my Mac Pro's performance and I will need to remove the heat sink then apply new thermal paste. Which one should I buy?

Answer 1

It is advisable to use a quality paste, for instance, Arctic MX6 when reapplying thermal paste during the Mac Pro upgrade. It is a complex material that has a high thermal conductivity level and makes it easier to transfer the heat from the CPU and GPUs to the heat sink. Apply a dot the size of a pea in the middle of the chip and it will spread when the components are put back together.

I have no expertise in this whatsoever, but as a Youtube commenter, it is my duty to inform you that you have used an incorrect amount of the thermal paste on your CPU!

I recommend spreading the thermal paste manually with a plastic spatula to a consistent thickness before applying pressure to finish the job.

I really like your content. You’re very calm & you explain everything. Where my expertise comes in is with the AMD GPUs. I’m an engineer at AMD and just wanted to briefly give the latest information on cooling technology. At AMD we use Thermal sheets on both CPUs & GPUs. 1) No mess 2) Good for 10 years 3) Out performs all brands of thermal paste. Thermal Grizzly is what I’ve spent many years testing. Also the pads are reusable. In my testing temperatures were 4-8 degrees (C) in extreme benchmark testing. The only other thing that beats it is Liquid Metal. Cheers

Would you ever consider using a graphite thermal pad instead of thermal paste for the cpu?

I bought it in 2017 and I need to replace the thermal paste!!!
