I bought a used 1155 Lenovo mATX motherboard from eBay. I installed it into a custom case with my own PSU and accessories.
Unfortunately the board came without a thermal sensor, there's a header for it on the board 'THER HD' - and as a result, despite the CPU being a cool 25°C idle, the CPU and chassis fans are spinning at a constant maximum/full speed RPM. With the sensor disconnected, it defaults the internal case temperature to read 125°C (!!)
The seller does not have the thermal sensor, it must have been thrown out with the case.
I'm wondering instead of buying a new sensor, if it would be possible to somehow circumvent or terminate/short the header altogether. I can't find any BIOS options relating to this, although possibly somebody could point me in the right direction.
Thanks in advance
