Oh just to compare to other DAC/AMP I've used:
FiiO E10K - zero static, stay cool, no problem with windows 10
SMSL M2 - zero static, stay cool, didn't get to test it on windows 10
Schiit Fulla - yes static, gets warm during use, mostly ok but bugs out once in a long while on windows 10
UDAC-3 - zero static, stay cool, also bug out on windows 10
This depend on how much shielding the case has, thick aluminum shell generally do help with...
