Thermal Interface -Video Controller ASD Error

After recently replacing my GPU card and chip, I ran Apple Service Diagnostic 3S123 and discovered I have an error that states: Thermal Interface -Video Controller:G92gt (test #4) -TIM Test 75 percent Gardband-Check that CPU heatsink is properly attached, using product spec theta dh + 75 percent guard band.

Any suggestions on how to fix that? I can't find anything online about it. I don't even know where to look on my machine for that item.

Answer this question I have this problem too

Is this a good question?

I was careful with the screws and believe I am using the correct ones. Could you take a photo of the screws I should be using if you have them handy? I want to verify I am using the correct ones.

When you replaced the card and GPU did you use thermal paste? I'd also contact Brickfence and ask them the same question since they did the repair.

I am using thermal paste and just replied it to the CPU portion again after the error/fail notice. After I reapplied it I got the same error message. Now I am wondering if it is the quality of thermal paste I'm using. I just emailed Brickfence too see what he suggest. Thanks for the suggestion and your prompt responses! I really appreciate it.

I've seen these types of error when the wrong screws are used (or missing) from the heat sink. I'll be interested to see what brickfense suggests.
