CPU Fan always on full power on my Vaio
I have a Sony Vaio PCG-K315S
Processor is a Mobile Intel Pentium 4 3.06Ghz / 533Mhz System Bus / 1MB L2 Cache
I recently had a HDD failure and had to do a rebuild on the new HDD, I have followed all of the drivers off the Vaio website. Now for some reasion the Processor fan is on full power nearly all of the time. Its as if the computer is working like mad. It even does this when there are no programs running.
I remember something before the HDD failure where the processor would run at half the speed, it doesnt do this any more, could this be why the Fan is always on because it is running at full speed.
Is the issue to do with Intel Speed Step?? I dont think it is set up plus cannot find it on the net, what about my Vaio Power management????
Thanks

i would check the sony vaio pages for a fan controller program.
I couldn't find anything on your exact model, but this is from a review of a similar Vaio laptop:
"Oddly enough the GPU seems to have more impact on fan speed than CPU as in "Stamina" mode the machine is mostly pretty quiet but in "Performance" mode even at light CPU load the fan can be pretty loud and annoying. I've played with various performance/fan speed options in the power management but as long as the NVIDIA GPU is in use, the fan runs pretty fast and can get pretty loud.
Sony clearly anticipated this limitation, as one of the programmable buttons on the keyboard had a default of reducing fan speed/noise."
This is from a review of a Sony VAIO PCG-Z1SP:
"Two further Sony utilities give you a high degree of control over the trade-off between performance, battery life and fan noise. Performance Balancer provides two tabbed pages -- 'Running on Batteries' and 'AC Plugged in' -- that provide preset and customisable combinations of LCD brightness (which affects battery life) and fan speed (which affects noise, and also CPU speed and therefore performance). More detailed power management profiles can be created in Power Panel; editable preset profiles are supplied for different usage scenarios such as DVD-watching, games, communications, presentation and so on, as well as maximum performance and maximum or ultimate battery life."
It looks as if the Viao's Power Panel is the way forward.

Can i not break the CPU if i start messing around with the power profiles.
My understanding is that the default power profiles can be edited to suit your requirements.
It is hard to "break" a CPU - if it gets too hot, the pc will simply shut down. However, the fact that the fan is spinning at full speed implies that either you should modify your power management settings via the Sony Power Panel software, or that the pc is running hot, which may be a hardware issue. Try the power management route first.

how do I access the Bios on my vaio

On my VAIO's it's either F2 or F3 (press that key immediately when you turn it on)
... in fact, you may have to press both => I just looked up a VAIO manual (first one I found -- not yours) and it requires you press F3 during the start of the boot process; and you will then be prompted to press F2 to get to Setup. Not sure if yours requires that sequence -- just try it.
You may also get a brief message telling you what to press when you first boot the system (many systems do -- but the message isn't there for long).

My Bios is a phoenix bios and does not have anything on power management at all, it all seems a bit basic, is there not a crack to unlock more features in the bIOS.

My understanding is that the power management feature on Sony Vaios is a software utility accessed via the Power Panel.
Do you have a Power Panel icon in your System Tray? If so, you can edit power management settings from there.
Right click the icon and select Edit/Create Profiles. The fan speed setting is accessed, I think, via the Thermal Control Strategy tab.
I would expect there to be something in the Sony manual supplied with your laptop about this.
