Question I tried to overclock my RAM speed and now one of my fans is reading -55C ?

[Didman]

Hello, I recently tried to change my ram speed to it's advertised speed of 3600, it then gave me a black screen and ran the fans at high speeds, I searched it up and told to remove the CMOS battery to reset bios, but all it took was to press reset on my pc and that reset the bios.

After I reset my pc, windows booted and everything worked fine, apart from one fan. I do not have a fan hub and only have two fan slots in my b550 gaming x motherboard so I used my CPU opt slot to connect the final fan and it worked perfectly fine. After all this, it now doesn't run and reads a CPU temp of -55 Celsius, the rest of them run at 500 rpm and the CPU fan at 700.

Is the fan/fans lost or is there a fix?

Welcome to the forums, newcomer!

Make and model of your ram kit used? What BIOS version are you working with on your motherboard?

and the ram is a Corsair vengeance RGB pro, 2 x 16gb ddr4 3600 and the bios is gigabytes f13 version of bios

According to your mobo’s specs you have
3 x system fan headers
1 x CPU fan header
1 x water cooling cpu fan header

So, what did you connect where ? It is not clear from your post
Or this is not your mobo ?

I have a CPU fan and 4 fans, I connected the CPU fan to the CPU fan header and 3 of the fans to the system fan headers, I then have one left over which I connected to the CPU opt header. The one connected to the CPU opt is the one having issues and not working

Sorry for not being clear

When you disconnect the fan from tbe ’cpu opt header’ (don’t know what it is. Is it the water cooler header?) does the CPU temperature read correctly ?
