Thank you for contacting Intel® Communities Support.
I am glad to assist you, please try a BIOS Update by Recovery option.
You can check how to do it here.
You can download the ''.bio'' file here
After the BIOS Recovery we recommend you to set the BIOS configuration in default by pressing F9.
I have updated the bios and will see how we get on.
Do I need to increase fan speed or change any settings or will default be fine?
I really like these NUC computers. I added the heat pad and I have not had any problems since. Also added some more RAM
I know the fans will not last forever and I was wondering where I could get a spare, do you have any idea please?
Thanks for your response
Glad to know that the unit is working properly for you
In regard to the spare fan, I regret to inform you that we don’t have any, but if the NUC is under its warranty there is the possibility to apply it
Here is the link where you can review the warranty
