Thank You, I was having fan noise issues with my NUCi7BEH and was trying to figure out how to pop the MOBO from the case.
This guide was fantastic, loads of dust collected on the heat sink, clean air and it seems to be running great now.
Ave temp before this clean out was 65ºC but would spike from 90-100ºC under any load at all, even the VMs just spinning up.
Now after clean, all is good, temps idle sitting at around 35ºC now and under load about 70º C. Huge difference.
Big Thanks to Vladimir for making this wonderful guide.
