Hi All,
I'm about to start in-depth research testing on this V2 card from a client. It most likely has just memory errors on it but I'm probably also going to replace the power semi conductors because someone's been fooling with them. This is from a load of parts with other V12 with similar issues from the same client. I don't know how in the world something like this happens but apparently someone at this gentleman's company decided it was a good idea to steal parts off these damaged cards. Why? Don't know. As we're trying to source replacement heat sinks and/or have them manufactured it dawns on me that I do not know what the original interface material was on the big processor but I don't want to repeat that same adhesion if I don't have to.
I was thinking trying out a different thermal interface material. I understand you can use ceramic or silver-based CPU thermal paste but what about those silicone thermal interface sheets or perhaps one of those new graphite CPU interface sheets (

I'm just not sure how thick of a sheet we need to be dealing with given that this used to be all some form of goo. I don't know the tolerance of any of these parts as there's no documentation for thermals. But supposedly the graphite sheet has thermal coupling that's twice as good as copper. But I don't know. I'd prefer to have the sheet stuck to the heat sink so you can lift it off at any time to replace chips and/or do maintenance.
Thoughts/Experiences?
Thanks!
