NUC7I5 Overheating - solved

[Hans-Linus]

Hi guys, 

 

i use a NUC7I5BNH  with 16 GB of Ram and a m.2 SAMSUNG MZVPW256HEGL as a htpc since it actually has had no problems with 4K Footage. 

 

Couple of weeks i noticed that my nuc got louder and louder. I monitored the temps and i discovered that the nuc got extremly hot (the cpu was in the high 60°C - from 64-68°C) with no load just idle. 

Then one day - i was just running spotify - i had an automatic shutdown because the nuc reached critical temps. 

 

I searched the net and didnt find much information (beside the usual 'nuc's are loud' and so on). 

 

Well i tried everything software wise (changing bios-settings and monitoring cpu and gpu usage). 

Nothing really helped. 

 

so i disassambled the little guy and well - not even a year in use - and right between the fan and the copper cooler was a pretty noticeable dustcollection. 

I cleaned it out and while i was on it i also changed the thermalpaste (had something from noctua lying around). 

 

And see - we are now chilling again between 40°C and 60°C depending on the load. 

 

so if anyone has some overheating trouble you should also think of cleaning the coolerassembly. 

I had to dismount the cooler to get to the dust and clean everything out but with this nuc model its not that big of a challange. 

 

i thought i'd share my experience with u in case anyone has similar troubles. 

 

Cheers
