by dricc15 / January 7, 2005 10:57 PM PST

Hi - I own a Toshiba Satellite A35-S159 and I was curious if anyone else has one and has the same issue I am. The fan on this notebook is extremeley loud and was wondering if there was a way to either shut if off completley or to quiet it. Would anyone have any info? Thanks!

Don't shut it off.

This is how the unit stays cool.

Have you called it in? I find making multiple calls may be required to get results.

I own the same beast. Keeping the fan openings and the exhaust open for air circulation helps a wee bit. You can tinker with the power management settings... in standby mode slow down everything which presumably generates less heat.
Kicker is, the fans come on howling even in standby mode. I am still looking for Hibernation mode...

u cant do much about the fan noise, theres a setting in power management utility where u can put it on silent mode, but if ur doing anything really processor intensive that might cause it to overheat and shut off
there is a hibernation mode in powermanagement

Loud Fan

In reply to: Fan noise?

My daughter has a Sony Vaio and when dust collects around the fan or the heat syncs, it produces a loud noise, sorta like an airplane taking off. Instead of taking the unit to a repair facility or removing the base of the unit to access the fan, I took a can of compressed air and cleaned around the fan and heat syncs via the open holes in the base. This made a hugh difference and you should have seen the dust and fuzz balls come out. The unit now runs as quiet as when it was new. When the dust and lint was still in the unit, the computer would shut off because of the heat build up. I hope this will help you too. Let me know!

No fan of your fan??
by server / March 18, 2005 9:18 PM PST

The fan is there to assist in cooling and is controlled by a thermal sensor. If your fan has become too noisy you may need a new one as the barrings may have worn down. Other options include:

You can use "Silent mode" (at the expense of cpu speed)Installing two rubber feet at the bottom to raise the laptop away from the table surface thus allowing for more cooling. Or you can google for a small program called Fan.exe Try Toshiba and Fan.exe I use it off and on but try not to overide the fan too much. You might also want to check what is causing your fan to turn on all the time by launching windows task manager and look at the performance tab. If a particular program or application is holding the CPU at 100% for more than a couple seconds then you know this why your fan always turns on. I've noticed even some websites, that use flash can cause the CPU to run 100% causing the fan to start. When I closed this web page the CPU went down and the fan turned off. Generally speaking, as the fan gets older the noise becomes louder.

Loud fan on Sattelite

In reply to: No fan of your fan??

I have a different Sattelite (A45), which screams so loudly that I have been asked to turn off my laptop in meetings so people can hear what others are saying.

I tried the tip above, and my CPU is indeed being kept at 100%. I don't know that I can do anything about it, though, since the application that is causing it to run so high is System Idle Process. I've noticed that before in Windows XP. Is there anything to be done about that?

>>I don't know that I can do anything about it, >>though, since the application that is causing it to >>run so high is System Idle Process.

If your CPU is @ 100%, 100% of the time then you
must have a rogue app running/hogging all the CPU
cycles. You must find what program is causing this. System Idle Proc always runs but is not the one causing your problems. shut down every running
program (one by one)and see if the CPU usage goes down.

Fan noise on a35 satellite

Fan noise on a35 satellite
by grajee / May 21, 2005 3:33 AM PDT

Hello All,

I do have Satellite A35-S159 which I bought 18 months before. Overall, I'm not happy with the system as it has been giving one or the other problem. Once in a
while, the system used to shutdown while watching a
movie via the DVD Rom drive. This used to happen when
I was in the US. I returned to India one year before
and since then whenever I watch a Movie the system
shutsdown in about 15 mins time. Twice, it shutdown while I was working on it as well.

I felt the bottom of the system and it was extremely hot. Since then I place a book underneath the laptop
such that the heated part of the bottom does not touch the surface.

I believe it is very much because of heat (especially
due to the Tropical Climate of Bangalore).

I would also like to think that this is more with the
Pentium IV laptops (compared to Cetrino based Laptops).

If someone has something else to share please email
me to

Time for an Operation....

Search for my post on Thermal Shutdown
several pages down. Since your machine
is already out of WARRANTY, then the
suggestion and tips there should help
you lots.

...Re:possible solution
by narin.s / December 7, 2005 2:34 AM PST

i have the same A35 S159 and used to experience the same probs, shutting down all the time due to overheating,this is probably due to the fans not cooling efficiently enough, which i realized is due to dust and lint,a possible solution is tryin to clean the fans,i`m not sure if a can of pressurized air will work, but what i did was to take the vacuum cleaner hose to the fans, make sure that the unit is off when your doing this, u can place the hose up to the fan vents at the bottom of the unit, i noticed a lot of dust and lint came through when i did this, it really helped with cooling, since cleaning it the fan noise has decreased and most importantly the unit doesnt overheat anymore, periodically doing this helps with cooling and the fan noise. Hope this helps, worked for me. Good luck!

btw, anyone with this laptop had probs with the dvd rom, mine simply stopped reading dvd`s, the CD-R and RW works fine, but it refuses to read dvd`s, i`ve downloaded millions of drivers and tried everything, concluded its prolly a hardware prob...

Wow- A vacuum cleaner!
by mindfull / December 10, 2005 12:19 AM PST

Hello All.
I have the same issue that's now come up on Gateway CX200X TabletPC. I've opened up the access panel & removed dust, then canned-air around the fan, then reinstalled. The noise is less, but still noticeably there...
Guess I'll try the vacuum idea and see how it goes. Also, if this helps, I noticed that the screws holding the fan in place affect the noise level. I don't encourage any major adjustments here, but a 1/4 turn lessened the noise significantly.
Open to any other insights.

2 things.
by R. Proffitt Forum moderator / January 10, 2006 2:47 AM PST

1. You've strayed off topic.

2. You deserve your own post.

If this was my machine I'd test DVD playback with my GEEXBOX boot CD from If the DVD played I'd know it's a software issue and look to uninstall and reinstall my DVD player software. If GEEXBOX had trouble with playing the DVD then I'd try a new DVD drive.

Cheap compared to repair shop rate unless its under warranty.

Vacuum cleaning works like charm!
by ck131 / March 18, 2011 9:36 AM PDT


Thank you for the tip! It works beautifully.

I have a Toshiba sattlelite A135 model. When it was new, the fan noise was not as noticeable as now. it was there, but it was fairly quiet. It's been a few years snce I bought it, and now it is making a noise like dirt bike.

I figure nothing to loose vacuuming the laptop, and after a minute of vacuum cleaning as suggested without any disassembling of the laptop, Wella! it is so quiet. It is so quiet, I can't tell if the fan is on or not.

Thank you, Thank you very much for the tip again.

Much of the same issue
by lost_thoughts / July 21, 2006 1:10 PM PDT

My Satellite A35 randomly shuts off if I leave it running for a prolonged period of time...but this can range from 15 minutes to 5 hours. Your issue may not have to do with the climate--mine gets really hot, too. Do you have problems charging it, or with the battery draining really quickly?

by lost_thoughts / July 21, 2006 1:02 PM PDT

I have had the same model for about three years. I took it to my nearby computer repair place for the fan and they found other issues...either my motherboard or processor needs to be replaced and they couldn't tell which. Apparently it was related to the fan. But the replacement of either of these would exceed the value of my machine. I may defect and get a Mac after all...Hopefully this helps.
