Hi - I’ve got a Mid 2011 27" Intel iMac. I need to replace my AMD Radeon 6970M 1GB (it fried). I will replace it with another working 6790M card. I’d like to use some thermal pads for the VRAM chips.. Does anybody know what is the minimum thickness for the pads that I can use are? (Fyi: Apple doesn’t disclose the gap distance between chips & heat sink plate). I appreciate any feedback you can give. Thanks. S
Sadly I haven’t measured the thickness of the pads. The different boards have needed different sizes. So I don’t try to take note. If you still have the original pad in good shape take a micrometer to measure it. Instead I use a finger gage to test out the gap and then use the same size or slightly larger.
