Speedstep would help as long as Sony weren't you-know-whats and hid/removed the option from the bios. Between Speedstep and adjusting the Windows power options like this,

will at least lower the CPU fan speed.

Actually, setting the "System Cooling Policy" under "Processor Power management" to "Passive" (instead of active) will reduce fan noise. The passive setting means that the processor is slowed down before the fan speed is increased.

That is one I didn't have to touch. For mine at least between Cool and Quiet (AMD's version of Speedstep) and the Q-Fan option in the bios (Asus motherboard), the fan does go up and down as needed (~2400 RPM fan currently spinning at ~1100 RPM).

Would it be possible unhide the BIOS option?

Does the Speedstep only prevent the cores from becoming hot or does it prevent the fans from running faster?

When it is enable it lowers the speed of the CPU and the voltage, as well as lowering the fan speed, and will speed each up as usage demands.

Not even if you tried real hard.

Figures. Sony computers suck.

How do most people feel about their VAIO notebooks?

I don't know if this can help solve the problem.

When I put the computer into "Sleep" mode and then one second later, come out of it, the fan goes back down to 2,200 RPM (from 3,800 beofre going into sleep mode).

Could this indicate anything?

@stormy13 that cool and quiet feature is really good what i think is very amazing is i hear almost nothing but the fan on the side of my tower pushing air out even my psu is quiet

as for the postmaster of this thread i would consider just changing all the fans and see what happens if changed if not and it continues it has something to do with your board settings

Im pretty sure it is a open shut case if you were to just spend a little change the fans and test i mean what could it hurt you have a reciept they can take the fans back if it isn't satifying the job

just a suggestion not the answer please rep the person that gave you the answer to solve this puzzle

but sleep mode is just idling the pc i don't think that would be effective cause take in mind after you do the wake up it will just resume the speed it slowed down from and most of all consider if the cpu's heatsink is in proper place because it sounds like something is heating up and the fans speed increases to make up for it and i would also open up the side panels and see where the fans go from there

your case could be really hot and the fans have to increase to compisate for the heat being shelled out by the unit psu cpu vid card
