Hello,

In the process of upgrading my mac pro. I'm looking to replace the pink thermal pads on the heatsinks which cover what I believe to be the voltage regulators. Anyone could point me to the proper thermal pads that I need?

I've also dissasembled the video card (HD 4870) which also needs the pads to be replaced as they are in pieces. Same question as above.

I think it only matters regarding how thick it is...I usually use the 2mm version, sometimmes even double (4.1 8creo upgrade), but its there in 1 mm too and more colors.

Bumping this thread as I have the same question - would this work OK on a 4,1 12-core CPU upgrade: http://www.maplin.co.uk/p/akasa-5mm-thermal-gap-filler-pad-a00nn

It says: "Thermal conductivity of 1.2W/mK delivers good heat transfer"

Is that 'good' performance?

I usually avoid Maplins, but there's one nearby and it would be quicker than waiting for delivery.

At 5mm, it would replace the old thermal pads completely. I've got a dual socket board.

Cheers!

Edit: I just realised that it was only 3cm x 3cm... useless.

Can anyone recommend a good thermal pad available in the UK?
