Hi,

My CPU heatsinks had gotten really dusty and my board as well. So I decided to do a cleanup. I removed all the cables and removed the motherboard from the case and proceeded with the usual de-dusting, air cleaning etc. I had to remove the fans off the CM V8 GTS because I had to get to the heat sinks below them as can be seen:

After cleanup I put everything back in place, connected all the cables and started my PC. At POST I was given the CPU fan error, BIOS was not showing any fan monitoring and all fan speeds were shown as N/A. When I checked on the cooler I saw that of the two, only one fan is working (the front one). So I though the cables may be switched or something, so I changed interchanged the two fan connectors ( i.e. connected the back fan to the line the front fan was connected to and vice versa). Now the back fan was working and the front one turned off. I do this interchange again and now the other fan is working.

As can be seen the front fan is not working but the back one is.

I checked everything I could possibly think of, nothing worked.

Would appreciate some help on this.

Thanks
 


Thank you for your reply.

There is no such option in the BIOS for cpu fan headers. This is what the cpu control in my BIOS looks like:

And yes that is the kind of fan splitter I am using
