I bought a new CPU fan from Newegg. It's an Arctic Cooling Freezer 64 Pro. I installed it but whenever I try to boot my PC tells shows
ERROR: CPU Fan failed. Shutting down to prevent damage to CPU
The fan is spinning away nicely. I've researched a bit and found some little answers. One thing I've noticed is my new fan as a 4 pin power instead of 3. But it says it's backward compatible and I've plugged it correctly (basing on their website). I've also read that maybe I should change BIOS fan settings..but my BIOS has no Fan setting "page" whatsoever.
Here's my PC specs.
AMD Athlon 64 X2 Dual-Core 4400+ ,2300 MHZ
4 GB Memory
BIOS version : Phoenix Technologies, LTD5.13
Microsoft Vista Home Premium
Would appreciate any help. Thank you very much!
