Make your own opinion I guess, but we left his on. I also can't see how that material could possibly block the GPU from contacting the copper.. as the pics show, the white mushy stuff had melted a bit, and i'm sure with some pressure that it would smush alot more... You can also see the size of the "tape", it's ultra thin..

Any I've been meaning to post some of these here for prolly a week or so, and now I have...

Many thanks for the pictures and your conclusion. I totally agree that this yellow stuff never was meant to be removed. You can actually feel, that it is kind of thermal material, as it feels quite cold imo.

What do you think about the black protective frames around gpu and bridge chip? Some users reported that the removal of these will give you a temperature advantage of roundabout 5°C.

Well thats a hard one.. We left his on, but thought about reseating it.. since the placement wasnt perfect and it bulged in one area around the GPU.

I guess it depends on your own preference.. His temps are usually around the low 50's or so (from memory) so I dont think it is really an issue..

Those black "support" pads did remind me of my 9700 Pro's Metal shim I removed when Installing aftermarket HSF.. So I guess as long as your careful, you could remove them.. The argument I read was that they were holding heat in around the GPU and HSI. I'm sure thats possible.. but they also provide leveled support for the HSF not to crack the corner of the GPU or HSI, which the GPU and HSI remind me of Athlon 32bit chips, Which CAN crack.. ( I have a cracked corner on a 1800+ and IDK if I did it or not ).

So if your careful with it.. I suppose it couldn't Hurt, but I suppose you could also remove the majority of it, leaving only 4 small pieces in the corners for stability.. That would allow air to flow by and still keep the support around the GPU & HSI.

I'm one of them. Removed the frame and gained 5 C° (61>56).
But I think that the problem could also be on the original heatsink spring based fastening system. Maybe it can't apply appropriate pressure on the (foamy rubber) frame to 'squeeze' it enough.

Later I mounted a Zalman VF900 and pressure il a LOT more....it bends slightly the card. So maybe no reason to remove that frame if a good heatsink will take place of the original one (not bad but loud).

That very well could be, a sloution might be to take a razor and cut away most of it, only leaving the corners. That way it would require less pressure to push it onto the GPU as well as allowing air flow under there, while still giving the intended support.
