link showing incorrect motherboard #2 temp

I have the ax860i with the corsair link, latest software.

When i view the software it tells me the motherboard temperature number 2 is MINUS 55 celcius. And then it just crashes. I have a motherboard testing system the real temp given by the board for that sensor is 20-22'C. So ive ruled out a faulty sensor.





So far i have tried the following:

updating to various bios - no effect.

Changing from windows 7 ultimate 64bit to 8.1/64bit - no effect

changing the legacy usb - no effect

Changing board headers - no effect

Making sure its the only thing using the usb headers - no effect

Used earlier software - bigger problem multiple errors

Motherboard bios changes, especially around usb handling - no effect.



So im hoping one of you guys might know something else i could try, or think of something ive overlooked. I dont really want to RMA it unless im sure its faulty, and as ive only had it less than 24hrs im not quite sure it is, but as you can imagine im starting to think it may be...
