I purchased an Intel NUC 6i7KYK1 roughly two years ago. Over the last month it has been shutting down and when rebooting gives me the "Thermal Trip" warning at boot.
I downloaded some CPU temperature monitoring software, and it is getting very hot very quickly, so I opened the case to watch it boot. It seems like the fan isn't spinning (And when it does, spins very slowly). I pulled the plug and replugged it in and have blown air/cleaned what I can see, but the fan still seems to be failing.
My question is, do I have any troubleshooting options here? I can't see an easy way to take the fan/heat sink off, and from what I have read the CPU cannot be removed. Are there guides for troubleshooting/replacing the fan for the NUC? I hate that all the components seem to be fine but a fan will cause the entire system to fail.
I found this Intel webpage on fan replacement options for NUC6i7KYK:
The i7-6770K CPU is soldered on the NUC6i7KYK motherboard and cannot be removed, but the fan can be removed and replaced quite easily, following Intel's fan replacement instructions PDF.
Yes, this document explains the process. Should you not want to wait for a replacement to be received from Intel, there are a number of place on the web where you can purchase replacement blowers for quite reasonable prices. In many cases, the blowers are even available through Amazon.
Hope this helps,
