Are you talking about your M.2 SSD(s)? With the NUC's - and this essentially applies to all NUC models - support for dissipating SSD heat through the chassis (this is what the thermal foam is for), there is no need for - and indeed no room for - M.2 SSDs that have heat spreaders attached to them. If you have a SSD with heat spreader, it will over-compress the thermal foam and severely reduce the efficiency of its thermal dissipation. Best thing to do is to remove this heat spreader.
This won't help with processor thermal throttling issues regardless. Best thing you can do for this is:
With these settings, I have no thermal issues (and fan noise issues are lessened) and the system performs well enough (better to lose a tiny bit of performance than to incur processor throttling).
Hope this helps,
Sorry yes... M.2 SSD's. I don't recall my Skull Canyon case having any thermal foam on the chassis lid but it's been about a year since I opened it but imagine it is pretty tight in there.. thanks for the reply!
