I have a VAIO VGN-SZ240P that I'm running WinXP SP3 on. In general it is a fine machine, but the cooling fan is quite loud. Does anybody know of a tool that I can use to view and manage the fan speed? I tried the latest SpeedFan beta, but it doesn't see the fan.

if speedfan can't see it then that should dent your hopes a lot. Is there any option in power management? some laptops like toshiba I think have a special power management like icon in control panel(toshiba power saver or something) with settings for it. I know yours is a Sony though. So maybe it doesn't. – barlop Dec 28 '10 at 4:36

Is it running Hot? You may need to clean the fan and heatsink.

Here is an article, not for Sony but you will get the general idea.

I just took the whole thing apart and cleaned it. No issues there. – Peter Loron Dec 29 '10 at 4:27
Usually Notebook fan problems are one of 3 things, overheating (heatsink problems, etc), bios issue (only Sony can fix this with an update) or a motherboard is defective. – Moab Dec 29 '10 at 13:57

Does this apply to you?

http://www.tomsguide.com/us/exit-the-sony-vaio-t,review-607-11.html

looks like it may have a power saving option, with fan speed options. icon possibly in control panel.

somebody here mentioned for his VAIO http://www.notebookforums.com/thread99131-2.html "If you open up the VAIO control panel, youll see power management, click on the +, then select power options, when the power options properties opens up click on the

"VAIO POWER MANAGEMENT" tab, look under system, thermal and you can choose "performance" or "quiet".

I have a BZ VAIO and my fan was very loud but since I put it on quiet its hardly noticeable, my temps are around 95f, very cool!!"

Either that Control panel is not available for my VAIO or I haven't found where to download it from Sony. It is not on my machine. – Peter Loron Dec 29 '10 at 4:29
@Peter Loron If speedfan can't control the fan then I suspect no software will. 'cos I haven't heard of speedfan failing to change fan speed, and then some other software working. – barlop Dec 29 '10 at 9:40
@Peter Loron maybe rmclock. I read somebody wrote notebookforums.com/thread99131.html "you lower your vcore, your cpu runs cooler, your fan runs less, the only way outside of that i know how to control the fan is linux". I dunno what he's getting at with linux. But maybe rmclock can lower your vcore, and/or processor speed and might cause a difference. – barlop Dec 29 '10 at 9:43
Some Sony's do have software, this is an update from sony for those that do have v1 apparently. esupport.sony.com/US/perl/… "Sony® VAIO® Power Management Utility Update" And it doesn't mention your model of laptop. That doesn't mean there isn't another for your laptop.. – barlop Dec 29 '10 at 9:44
I do not think the power management utility exists for your laptop, since you can't see it despite info on where it is.. And also, look at these two links. This laptop has it listed. Yours doesn't esupport.sony.com/US/perl/swu-list.pl?mdl=VGNTXN25N esupport.sony.com/perl/swu-list.pl?mdl=VGNSZ240P#div_pos_116 – barlop Dec 29 '10 at 9:48

What if you plug in a laptop cooling pad underneath your PC? A good one can reduce your CPU's temperature by five degrees Celsius or so. (I've never used one; I based that claim on a CNet review of one such pad.) I don't know much about hardware, but maybe your laptop will detect this cooling effect and slow down its fan?

Disclosure: I have no connection with Antec or CNet.

If you work in a dusty area, like Delhi, India. You should open you PC and clean the Fan, that's the best way to control your fan. I've to do it each 5 month, you PC will get lower heat and lower fan speed
