Corsair Link saying my motherboard is 260°F

So I've only ever checked my temps in the BIOS, but I got the H100 v2 liquid cooler and installed it into my computer. It recommended I download Corsair Link to monitor my temps and affect the RGBs so I did, temps for my CPU and GPU are around 60°F and it lists four motherboard temps. 57°F, 62°F, 61°F, and 260°F; seems a bit odd as the BIOS only ever had one motherboard temp and now one of them is super high. I have an MSI Krait z170A motherboard, if anyone has any idea why I'd appreciate the help.
