you have an excellent way to test greases
e-mail me your address
I'll forward it to Colin or Nevin and I'm sure they'll send some Arctic Silver (which is what I thought you were using)
the value is 'known' wrt a processor/package, it is an integral part of all thermal load/temp calcs
given the similar effects of an IHS, the 'known' value is used pretty much across the board - 0.07°C/W for Shin Etsu G-751
note the value is to only 2 decimal places, this reflects the uncertainty due to application and not the equipment's capability
and since these calcs are to ascertain compliance with thermal design limits (or goals in development), the value is conservative
I am referring to TIM2, TIM1 under the IHS is a different kettle of fish
