Motherboard thinks CPU is at 100c

[Sreno1]

I recently rebuilt my system into the Crystal 460x case, the case looks amazing but the CPU cooler is spinning at 3000+ RPM. It is the intel stock cooler so it is extremely loud.

 

I checked the bios and the motherboard cpu sensor say's it is at 100c, but the CPU is under no load and Advanced System Care 10 says that it is at a cool 27c. 

 

What could be going wrong to make the cooler spin so fast?

 

Motherboard: Gigabyte Z170-XP-SLI

CPU: i5-6500 (I know it's not an unlocked CPU, didn't know what I was doing when I built the system).

Since the only change was a case swap, I think it's worth checking that the mobo isn't shorting on the case like from an unneeded standoff that needs to be removed.

yep - what @meenmeen1103 said was my first thought too.

did you remove the cpu from the board when swapping the case?

unless your ambient is like 15deg C that temp can't be possible

I kept the CPU, cooler, and mobo together when swapping.

It's been reading that cool in both cases.

what's your room temperature? the CPU's temp cannot be lower than that - it's physically impossible air cooled

quick question: have you messed with the BCLK clock?! from what I recall that will mess with a lot of things, including temp reading

27 C isn't that low, ambient is about 65-70 F in my room. I haven't messed with BCLK oc.

 

I don't really care about the motherboard saying my CPU is at 100 C, I just want the cooler to not be as loud.

that explains it

use HWinfo: https://www.hwinfo.com/download.php - look at the individual core temps and the package temp

do they read 100deg ?!

So my system care software is inaccurate, but HWinfo still show's respectable temps for the CPU.
