How thick is too thick?
I understand that not thick enough reduces mounting pressure; and that mounting pressure, generally, decreases the thermal resistance of the pad.
and too much thickness can cause problems with deflection.
but where does more become TOO much??
for my current situation:
GPU (ASUS TURBO1080TI-11G)
Gap is sub 2mm - (measured with crap caliper, by measuring down from the top of the metal plate, used to sink heat away from the VRM and memory chips, to the top of the VRM chips, then subtracting the thickness of the metal [metal thickness it more than 1mm, less than 1.5mm, probably 18 gauge])
2mm pads leave an indent, and would work.
would 2.5mm pads work better?
3mm pads were too big and caused deflection, BUT, would they squish down more after being heated and cooled?
would a sandwich of 1.0mm Fujipoly Xr-m (17w/mk) + 1.0mm copper shim + 0.2mm Carbonaut be too thick ( < - my current desire) OR would this only give me that extra mounting pressure needed to reduce thermal resistance.
I realize that it is heavily dependant on many factors (pad hardness, pad properties, where pressure in being created, etc. . . )
but
I just want to know ball park, is +1mm too much, or is +0.35mm too much
