Different CPU Fan Speed Readings

by kbxtra / October 9, 2005 6:52 AM PDT

I just noticed in the Post Screen that the CPU Fan Speed is showing double the rpm (e.g. in the BIOS the CPU Fan speed reads 6,026 whereas the POST Screen reads 12,053 rpm). Is there something in the BIOS I need to change? It hasn't caused any instability as of yet just wondering why the readings would double.
The one thing that I have done recently is to flash the BIOS. The following are my computer specs.

DFI LP875B Rev.B1 Phoenix-Award Bios v6.00PG Dated 01/20/2005 with Enlight 420watt p/s, 3 80mm fans, P4 2.8c GHz FSB 800 with TT Spark "7"| Corsair Value Select 1GB 512MBx2 ram DDR400| Lite-On 52x32x52 CD-RW, Plextor 708-A DVDR/RW, Standard Floppy| Seagate 80GB, Seagate 120GB Ultra ATA/100| GeForce4 MMX 440 64MB|Windows XP Pro Sp2.
Any help would be appreciated.

Probably a bug

I once had a system where the BIOS reported my 1.1GHz Athlon as a 600MHz. It's probably just a harmless bug in the BIOS and nothing to worry about.

Are either of the readings correct????

At 6000 rpm that seems that it would be a very noisy fan.

I had the fan on the CPU at max Happy at the time. I have a controller. The readings in the BIOS are correct, it's just at the Post Screen that I get a double reading of the rpm.(e.g. now I have the cpu fan set to 4821rpm but the Post Screen reads 9642rpm). I also get a correct reading with MEM5 and Everest Home Edition.
