Have to throw in some background
The design intent is for the compound to harden after a couple of weeks of use and as a result molds itself to the surfaces.
IC Diamond is highly bulk loaded 92% diamond, couple % carbon black and insignificant % amount of binders so little significant shrinkage. Common OEM recommendation is for bulk loading above 90% to increase reliability. Diamond/Carbon are pretty inert under these conditions, the basic material components do not change much.
The "setup" of the compound is more like a like a catalyst hardener than a more liquid type compound that bakes or pumps out. hundreds of examples as a typical problem are available of pump out are available in technical literature or anecdotal y
We are pushing almost 3 years on the ICD sales and ICD has been extensively vetted in a number of OEM labs and validated for use in some mission critical military systems.
Complaints on reliability generally as a % of sales run about .00002% to put it in context. It is near impossible for us to tele- troubleshoot all issues without examining the conditions first hand.
I had one guy where the paste failed on him in a week, I gave him some avenues to investigate and never heard back so I do not know if there was a solution or not. But like I said In context The problems have been minor
123 Bob @ xtremesystems does folding at home with about 20 machines and has been running ICD for approximately 2 years on overclocked systems with no change in temps and my own personal office PC has been running 3. 5 years with no change in temps.
I have a recent example of a gpu application that was running 1.5 years 24/7 folding @ 80C +/- that failed, but most data that I have is run at less extreme stress over the extended period.
Use acetone to clean, put a few drops let sit for a minute and it will wipe right off. Alcohol is a lousy solvent and not recommended but leaves little or no residue so use that as a final wipe.
