[SOLVED] low temps but fan always on

I don't know why but since yesterday my laptop's fan is always on, it never stops even if the temps are low:

$ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1:        +14.0°C  (crit = +120.0°C)

coretemp-isa-0000
Adapter: ISA adapter
Physical id 0:  +35.0°C  (high = +84.0°C, crit = +100.0°C)
Core 0:         +35.0°C  (high = +84.0°C, crit = +100.0°C)
Core 1:         +33.0°C  (high = +84.0°C, crit = +100.0°C)
Core 2:         +31.0°C  (high = +84.0°C, crit = +100.0°C)
Core 3:         +33.0°C  (high = +84.0°C, crit = +100.0°C)

cat /sys/class/thermal/thermal_zone*/temp
14000
36000

$ uname -a
Linux r4 4.6.3-1-ARCH #1 SMP PREEMPT Fri Jun 24 21:19:13 CEST 2016 x86_64 GNU/Linux

I know this has been asked before, but I couldn't find anything useful on the cases I've found. I'd really appreciate any help. Please let me know if there's any other info I'd need to post.
Thank you!

Re: [SOLVED] low temps but fan always on

Details about your laptop would be helpful. Also, check if there is any relevant setting in the EFI/BIOS.

Thank you for answering, x33a. My laptop is a banghó max g01 i7 (http://www.bangho.com.ar/notebook-max-g01-i7/p), I'm from Argentina. I'll check my BIOS, though I don't know what I'm looking for.

I would start by checking if you see the same problem with linux-lts, as this might be a problem triggered by a software bug.

That said, you might want to check if there are any bios updates, as those sometimes fix weird problems. I would start on the page you have linked to, search in the driver area as it seems common for manufacturers to put bios update in there.

I would also try check if your laptop is a re-branded/barebones machine, as you might be able to get a bios update directly from the manufacturer, _however_ be very careful and check for any reports of problems about updating to a bios directly from the manufacturer, in case of doubt don't update.

Re: [SOLVED] low temps but fan always on

I couldn't find anything realted to the fans in the BIOS. It doesn't have many options. Btw, uefi is disabled.

If it's any use, my BIOS version is 1.03.07RPC2.

I would start by checking if you see the same problem with linux-lts, as this might be a problem triggered by a software bug.

I've tried booting from a LTS live-usb, but the fan is always spining loud and high. It never comes down, it's like that since I turn on the computer.

That said, you might want to check if there are any bios updates, as those sometimes fix weird problems. I would start on the page you have linked to, search in the driver area as it seems common for manufacturers to put bios update in there.

It is, indeed, a rebranded machine. It's built from a CLEVO, but I can't find which is the original model. So I don't know how to check if there's any BIOS update. And I'm up to date according to bangho.com.ar website Any other ideas?

Re: [SOLVED] low temps but fan always on

This was solved after an update. I don't know exactly which was the cause of the problem, but I'm still using the same kernel, so that's not it. Weird. Anyway, solved.
