Shuttle XPC SB61G2v3 Smart Fan problem

Hi all,
I' hoping someone can come up with a suggestion. I've just updated the BIOS on my Shuttle and installed an intel 3.2Ghz processor. Everything works, except the fans are at full throttle. When I had a 2.4Ghz Celeron, it all worked fine, but now the fans never change speed and is very noisy. I've checked all the cables, and they are all connected.

I've edited the BIOS, and set the fan speeds etc. but still to no avail. I even installedthe XPC tools, and the temp. is about 46 degrees, which is way less than the default 68 degrees.

Does anyone have any idea?

Thanks in advance

Ray

Have you flashed to the latest BIOS? Perhaps the old BIOS doesn't understand the newer P4 chip you have.

Hi notmetoo,

Check out the latest BIOS (FB61S30S.bin) at:

Also, check out Shuttle XPC Tools at:

HTH,

The BIOS appears to have several recent upgrades, therefore flashing it might well solve your issues... as might resetting CMOS default values.

The actual BIOS history appears below.:cool:

You can download an iSO file ready to burn to CD-R from the following link, therefore avoiding the risk of using WinFlash (instead you set your CD-ROM to 1st boot device in the BIOS and reboot with the burned iSO BIN BIOS image in situ in that drive and it'll walk you through the update).

Hy there!

I just bought a XPC rig just like this. I'v put the latest BIOS and after that strange things started to happen.

I can report the same problem notmetoo has, also the tzic-tzac noise from the PSU.

Can anyone help? I've tried everything, Speedfan, XPC Toolbox and BIOS settings, nothing works, the fans just wont be silent.

When the sistem boots up, before the POST, the fans go silent for a second or so, after that full throttle and they stay that way.

I'm desperate, donno what to do, please help.

As i found out yesterday, i have the v2.1 PCB mobo on my XPC. Fan problem solved by flashing the right BIOS.
