NUC seems also stable with prime95..
Which software is the most reliable to read temp from the NUC?
I've tried with another 12V power adapter with no luck (sometimes boot is ok, sometimes it displays the warning...)
Thanks for joining the NUC community.
Sorry about the trouble. I understand you are getting thermal trip errors while booting up.
Please try to perform BIOS recovery, if this is a BIOS issue, then it might be fixed:
File name: FY0034.BIO
Instructions for BIOS recovery available below:
At this stage, only the BIOS provides temperature readings for your motherboard model.
I already tried to upgrade to latest bios (34), and I also tried 32 and 28...
Sorry about the trouble.
At this stage, it seems to be a BIOS chipset issue. I recommend contacting Intel support and request warranty for your NUC.
www.intel.com/chat and contact Desktop support.
I'm seeing the same thing on reboot. Although I've never seen the motherboard ambient temperature above 44C, I'm seeing the Processor Thermal Trip error every once in a while on reboot.
I'm running Linux Debian Wheezy and hardly pushing any load on the box. It's basically just running the OS.
I'm running BIOS 34.
Mainly just replaying to share the fact that I'm seeing the same warning on boot.
Thanks for sharing your experience.
I've the same issue,
running bios 34, Ubuntu 14.04 - amd64 bit version on NUC2820
I looked in the bios settings for the fan and observed that the 3 temperature points look awkward:
- critical temp 88 degrees
- control temp: 80 degrees
- full fan temp: 88 degrees
It looked to me that full cooling only kicks in when critical temperature is reached (too late), so I changed the temps to:
- critical 88 (the same)
- control point: 68
- all on: 78
Now the thermal trip did not occur during the last 10 reboots.
Furthermore (but that's XBMC specific): turning of the RSS feed in XBMC caused the temperature (measured by lmsensors) to drop by some 20 degrees!
Maybe this can help others.
I've returned my unit to my retailer. I keep you posted.
Thanks for the feedback. I am looking forward to hearing from you.
I have the same issue with a new Intel NUC
- Bios : v34
- RAM : PC3 - 10666 - 1333 Mhz Low voltage
- SSD : Sandisk Ultra Plus 256 Go
- OS : XBMCBUNTU GOTHAM 13.1
FYI - We just got back one of these NUCs that is showing the thermal trip warning so that our hardware team can investigate.
That's great to hear. We appreciate the follow up Lois.
Please feel free to contact me directly if the team has any questions. We have 20 of these that are going to be deployed in about 3 weeks so we're happy to help track this down before these ship.
I have an update about the NUC we got back in with this problem. Turns out, it looks like the unit had been dis-assembled and the fan/heatsink removed and put back on with the appropriate thermal interface material reapplied. That certainly would cause thermal issues.
I see in this community thread, you all are reporting this error on brand new units, so I'm certain nobody is messing around with the heatsink. So, we are back to the drawing board - we need to get more failing units for analysis.
If anyone here who has this error wants to arrange for a swap, let me know.
I'm willing tot swap my unit, don't know if location is a problem. I assume you don't need SSD or RAM, only bare unit.
Please let me know if I can help (and how to proceed).
