VGN SZ1 - Cooling Fan running nonstop

gesada — Tue, 05 Jun 2007 19:20:35 GMT

Hi
I am working with a Vaio VGN SZ1 XP/C. Perfect laptop just the fan in noisy and running nonstop even when only working with office programs. Is this normal ? Anybody having the same experience ? In some magazine I read that this laptop is so quiet, well not mine.
Your comments are appreciated.

Hi gesada and welcome to Club Vaio.

First thing to check is if you have a fan problem or a overheating problem.

Download MobileMeter and let us know your CPU temperature. We can take it from there.

Hi Blencogo
Thanks for the info. Will let my computer run this night and check temperature.

Compute was running all night at speed mode, no other programms open. Max temperature was 48 degrees. Fan is running.
thx.

Hi gesada,

The temperature seems fine, have you got your Power management setting set to Adaptive for your CPU..?

Does the temperature increase when you have several programs running..?

I am not suprised at this time of year, but it's best to check it with MobileMeter just in case

I have a VGN-G11VN with Windows Vista and experience the same problem -- fan running (nearly)n all the time even if I have only a single program open(like Firefox or Word).

I tried to run MobileMeter (in admin mode), but it seems to be incompatible with Vista (like many programs that need access to the hardware).

I run this widget in the sidebar that shows CPU and memory usage -- even if CPU usage is very low, the fan is running.

I also played with the VAIO Control Center / Vaio Power Management where one can adjust the CPU fan speed (level 1 .. 5). Seems to have no effect at all (currently, I use level 3).

BTW, the temperatures in Germany are quite low at the moment, so this is not the problem 🙂

Hi, same Problem with VGN-BX197XP Fan is always working (the noise also ) at almost full speed , even with Adaptative mode actived or Vaio Ultime battery level. At full perf Mode it's an hairbrush !!

You could try speedfan and see if that will reduce the fan speed and noise. Has worked for other people i know but again its a hardware dependant thing. Check out the website .

Thanks for this link. I installed speedfan on my VGN-G11VN. When (more or less) no other program than speedfan and FireFox is running, CPU load is at about 10%. The temperatures are:
HD0: 35C, Temp1: 67C, Temp2: 66C, Temp3: 66C, Core 0: 57C

Looks like too high temperatures to me, but I have no idea what the "correct" values should look like. Any ideas? The machine is run at normal room temperature (not in the sun), I guess about 20C.

Well first off the hard drive temperature is completely normal, 55 is the max so 35 is really optimum.

The CPU is very hot although its not outside the max limit for the processor. All i can suggest really is checking for dust in the vents and make sure you use it out in the open (ie not next to a wall) with a fan blowing into the vent if you get really concerned.

Is the fan running at that temperature?

Re: VGN SZ1 - Cooling Fan running nonstop

sintek — Thu, 28 Jun 2007 18:28:15 GMT

Yes, the fan is already running, but at moderate speed (yet already annoying in a quiet room). I think the fan is only not running directly after I start the laptop, but after a (short) while nearly never stops anymore.

When I start a program that eats more CPU power, load usually goes up to 90% or so, and the fan blows like hell. Temperatures stay at about the same as I mentioned in my previous post, so this seems to be fine, but the noise really is unbearable (for me and others in the same room 😞 ).

Since this is a completely new laptop (only a few weeks old), dust etc. cannot be the problem, and air circulation around the laptop is not blocked.

Is there any way to reduce CPU load and thus fan speed that comes with the Vaio tools (or Vista)? I tried, as I explained before, VAIO Control Center / Vaio Power Management / CPU fan speed, but this didn't change anything. Switching off Airo also didn't help. I fear the weak CPU (1.3 GHz) simply cannot handle Vista. Is downgrading to Windows XP possible on this machine (VGN-G11VN)?

Re: VGN SZ1 - Cooling Fan running nonstop

MattWilson — Fri, 29 Jun 2007 08:24:48 GMT

Does the CPU every reach 0% if nothing is running?

Try seeing which processes are using upi the CPU on Task Manager (Processes Tab).

I think its not going to be a problem easily solved as Core2Duo processors and intel processors as a whole do run very hot.

Re: VGN SZ1 - Cooling Fan running nonstop

sintek — Tue, 03 Jul 2007 13:48:06 GMT

0% is never reached, even if no user program is running -- there are about 10-20 or so services that consume about 8-20% all the time. The only big processes are dwm (desktop window manager, abot 3-5%; and sidebar, about 2-3%; the sidebar only shows calendar, clock, and CPU usage); all other processes usually consume less than one percent (each), but they some up ...
And, as I said, in this mode (no user programs) the fan already runs continuously with temperatures as posted before.

Probably I shouldn't complain -- I have a 1.3 GHz single core CPU (VGN-G11VN), not a state-of-the-art dual-core one, but I would have expected such a machine then to come with XP and not Vista.

Well if that is the case then may i suggest that you disable some of the resource hungry vista features and see if that makes a difference.

1. Disable aero transparency

2. Disable sidebar

3. Disable Indexing - C:\ properties uncheck the box that says "index for faster searching"

Re: VGN SZ1 - Cooling Fan running nonstop

sintek — Thu, 05 Jul 2007 12:59:59 GMT

I already had aero transparency deactivated; now I also removed the sidebar and switched off indexing. Did not help 😞
Speedfan currently even reports the following temperatures (with FireFox being the only user process): HD0: 40C, Temp1: 72C, Temp2: 70C, Temp3: 70C, Core 0: 59C
BTW, what are the maximum temperatures?

Re: VGN SZ1 - Cooling Fan running nonstop

MattWilson — Thu, 05 Jul 2007 13:41:36 GMT

I think it refers to the maximum temperature that the processor will work at before being shut off. But i could also be the max temp it had been at since running it but i can't remember.

Re: VGN SZ1 - Cooling Fan running nonstop

sintek — Thu, 05 Jul 2007 14:05:43 GMT

I wanted to know the maximum temperatures that my laptop will endure; these maximum temperatures are not displayed anywhere (using SpeedFan). So: is more then 70C ok (for Temp1/2/3)?

Re: VGN SZ1 - Cooling Fan running nonstop

heltenkelt — Thu, 05 Jul 2007 14:54:04 GMT

I got an VGN SZ3XP/C and I have the same problem:
downloaded the SpeedFan and Mobilemeter and the temps are:
Hd: 40C-ok
temp1: 62C
temp2: 67C
temp3: 66C
core0: 55C
core1: 52C

CPU-usage is switching, right now, between 0,0% and 3%.

Twice my computer shutted itself off, probably due to selfprotection from overheating, but that was probably cause the fan-exit was blocked. But now it shouldnt be as hot as it is, should it?
Please comment/help.

I LOVE my Vaio!
