VAIO S, has anyone managed to calm down the FAN?

Has anyone gotten to make the fan of this model to spin slower or even turn off when the computer isn't performing high demanding tasks? Mine blows at 100% power 100% of the time; I don't care as much about the noise as for the fact that it drains the battery so quickly.
Thanks.

 

It's not the fan that drains your battery down, it's your CPU. Check your running tasks, there is some software making your CPU sweat.

 

Thanks for answering pyr0!
No, believe me, I'm very minimalistic with software, I've removed all the bloat and my only resident is a firewall (I don't even use an antivirus). This VAIO is supposed to last 7 hours and it's enduring like 4 or 5. The fan may not be the only responsible, but at this pace it sure has to drain some power. It's mechanical after all.

 

100% speed 100% of the time is too much. something is consuming too much CPU resource just as pyr0 said. one suggestion though: put the graphics switch on STAMINA which disables the hot AMD dGPU and runs the cooler Intel iGPU.

 

You can also go into the VAIO Control center and change the thermal profile to silent. It caps the cpu a bit (no full turbo anymore) but for desktop use even at base frequency it's already fast enough. It will be very silent when you do this. While you are there, change the VAIO key to change the thermal profile so you can switch between them with the press of a button

And of course, as above switch to stamina mode. Running on the AMD graphics drains power and introduces more heat, not needed if you're not gaming or photo/video editing.

 

Thank you darxide_sorcerer, I'll look into that. There's also the chance that I'm missing some driver. I moved the original W7 partition and I'm also using XPx64 and XP regular flavor, so technically speaking I'm outta spec .
I'm gonna re-revise everything, although I just discovered that the BD-ROM quitted on me (doesn't read media any more) so that's my main concern as i'll have to resort to the warranty as early as 1 month into use

 

I'd go back to windows 7 to see if the Blu-ray works there...

In any case, any reason you're running XP as your daily driver? You could use VM when you need it?

 

Nope, it's a hardware failure. Doesn't read anything from nowhere and doesn't make the spinning noise...

-I find it to be faster and more responsive (this wouldn't hold in a VM)

-I believe it drains less power (again, this wouldn't hold in a VM). In my previous VAIO, which came originally with Vista, battery endured 2x longer in XP. I relay a lot on battery, so this is an important reason. However, I'm not yet sure this holds true for this model.

-Too many applications and personal settings on them that I don't want to reinstall/reconfigure. I sysprepped the system from a previous machine and port it to this one.

Also, the sad truth is that I'm too accustomed to XP and just feel more comfortable working there. I know... I'm probably getting old

FAN UPDATE: As I write this, I realize that the fan's no longer as crazy as it used to. In fact, it feels and sounds completely off. I haven't done anything except play with a few settings in the pyro hacked firmware. I hope it's just that and not that it's broken!!

FAN UPDATE 2: No, the fan's not broken. The problem just got fixed by pyro's BIOS version.
