I am using a fit-PC3 low power as an audio server. Everything works fine but there is a major problem: as reported in http://www.fit-pc.com/forum/viewtopic.php?f=80&t=5212, the device (not the hard disk which is a SSD) is noisy.
My BIOS is version BZ_2.1.0.333_7. The current version is SBC 2.1.0.333_13.
The BIOS changelog on http://fit-pc.com/wiki/index.php/Fit-PC3_BIOS_ROM_Files suggests that with SCT_2.1.0.333_8 "Aggressive CPU power management (CPU noise reduction) is implemented".
My question is: is there a realistic chance that I can get rid of the noise (or maybe just reduce the noise level) by upgrading the BIOS ?

Re: BIOS and noise
It is long ago I updated the BIOS on my my fitpc3, but after doing so and turning
the aggressive power saving off, I could no longer hear the noise. Note that it also makes the device use more power.

Re: BIOS and noise
Thanks jens, do you remember exactly which option in which menu did you turn off ?
My understanding is that upgrading from SCT_2.1.0.333_7 to SCT_2.1.0.333_8 would allow enabling aggressive power management. If there is a way to disable (aggressive) power management without upgrading the BIOS I would first try it.
B.t.w., do you know if there is a way to save the current BIOS for re-installation (e.g., in case an upgrade brings more problems than it actually solves) ?

Re: [Solved] BIOS and noise
I have upgraded the BIOS following http://www.fit-pc.com/wiki/index.php/Fi ... IOS_Update. The update was succesful. In the new BIOS aggressive power management is disabled by default. The ticking noise is gone (enabling aggressive power management brings the noise back).
Re: [Solved] BIOS and noise
This option in the BIOS was added exactly to solve the noise issue. Sorry, no, I do not know to save the old BIOS, but as far as I have noticed the new BIOS works just fine.
