Hi,
I bought a nuc, and it was working fine for about a week. However now it has started freezing up if I leave it alone for a while. The last thing I see in dmesg is appended below. I found the following topic regarding 525 120gb overheating issues
Re: Intel mSATA SSD 525 120gb crash
To verify, I ran a smartctl -A /dev/sda | grep Temp and found that for some heavy disk work (endlessly copying a 3gb large file), the temperature goes up to 91C.
190 Airflow_Temperature_Cel 0x0022 093 105 000 Old_age Always - 93 (Min/Max 21/105)
Could overheating be my problem? Full smartctl -x output last in post.
