TOSHIBA M35 FAN

I was wondering if any owner of the new Toshiba satellite m35 can confirm that its fan is running all the time when the CPU control method is set on fixed. If I change the CPU control method to Auto, the fan cycles (it is on for about 20 seconds and off for about 5 minutes). The fan is quite annoying on both cases. Does this also happen to you? Is there any other setting to make the fan rest more?

Thank you for your input.

Best regards,
Jordi

 

I believe the fan runs all the time because of the heat the the P4 CPU is putting off. That's one major issue using a P4 DTR CPU in a notebook, there's only one way to cool off the CPU, and that's to use fans. This is like the HP notebooks, but theirs have 2 fans, one that occasionally comes on, while the other always runs. I don't think there's any other way to reduce the fans operation.

Thank you for your reply. This computer is not running a Pentium 4, but a Pentium M. Isn't it supposed to run much cooler?

Please advise.

Thank you.

Best regards,

Jordi

 

You might want to return the system to the retailer you purchased through after a call to Toshiba tech support. A Dothan processor should not be putting out enough heat to have the fans on all of the time.

I would also suggest not fooling with the fan controls unless you know exactly what you are doing, as problems such as this can arise.

Good luck!

Thank you for your replies. I checked the Bios but there is no option regarding the fan. Before returning the unit, I would like to be able to compare its fan behavior with another user of the same computer to find out if this unit is defective or if it's normal behavior. When I have the CPU on fixed setting, the fan is almost always on whereas when the CPU is on Auto setting, the fan is usually off and it turns on for periods of about 20 seconds. I bought the computer at Circuit City and this is the second replacement because the first one had a dead pixel. If this behavior is not normal, I will try to get a third replacement. Otherwise, unfortunately, I will have to return it, although I will have to pay the 15% restocking fee (about $300).

I called tech support and they assured me that this was normal behavior. I doubt they knew what there were talking about, since they also told me that Celerons run cooler than PM!!!!!!!

The reason why they said that is because I said that my other Toshiba was a Celeron and the fan was really quiet compared to the PM computer.

If anyone has the same computer, please advise.

Thank you.

When I select the regular windows XP power schemes (such as Home Office/Desk), the fan is always at full blast all the time as well. Any input? Tomorrow is the last day I have to keep the computer before I can return it to Circuit City.

Any advice will be appreciated.

Thank you.

It is true in many cases that, while Dothans have better battery lives, that they run very slightly hotter than their 130 nm counterparts. But to have the fan on that much is very concerning at best. It sounds like a defect to me.

Then again, I am no Toshiba tech support rep...[ ]

 

I would like to ask if i use this laptop only for serfing on the net will the fan run that much ?

 

The fan on my Toshiba Satellite m35 runs ALL the time when the power setting is set to fixed CPU speed, no matter what I do, even if the computer is idle. The fan is pretty loud. It annoys me a lot. If I set the power savings to Auto CPU speed the fan turns off and turns on at cycles of a few seconds every 2-3 minutes. I would like if this is normal for this specific computer. I am about to return it because of this. Anybody who owns this computer can comment on this?

I would really appreciate it.

Best regards,

Jordi

 

Surfing the web is not a very intense task, therefore I would say the fan would not run at all. I dont have experience with this particular laptop, but my laptop's fan doesnt run while surfing the web, and I would guess that this would apply to most others as well.

From the looks of things, it doesn't seem like a lot of people have this notebook or have this issue.

The issue with the fan does seem to have something to do with the power management (PM) settings on your notebook. I mentioned before that the fan speed could be linked to the PM setting. This link could be happening because of the Toshiba PM software. Have you tried uninstalling the Toshiba PM software and running off the standard XP PM software?

I checked their site and they have a couple drivers/utilities that het installed that have to do with power management. This may be the cause of the problem. If uninstalling these specific drivers/utilities don't work, try reloading the OS fron scratch rather than from the Toshiba Restore CD's (last resort).

Good Luck!

Can someone help me? I am about to return the computer.

Thank you.

On my sample, the fan is NOT constantly on when PM is set to full power (Fixed CPU) under the Toshiba's PM utility. My fan does come on frequently but since this unit is different than what I have in front of me, a couple of TP's & Compaq's, it's difficult to say whether it's excessive or not. The mere fact that it's driving out warm air means it'w working in my book. I suggest you take the unit to the store & sit it side by side of the display unit, try to run similar routines and see if the fans perform somewhat equal.

If your 1st & 2nd units both behave the same, I would think it may just be a personal preference. This sort of thing is very difficult to get the "right" answer on a forum because we all have different perception. Good luck.

 

Thanks for your answer run1! Yordi32, what about your laptop when you are on the net? does the fun continue to work so annoying?

 

When CPU is fixed, the fan is ALWAYS at full blast (very noisy), even if the computer is idle. When the setting is at Auto CPU, the fan starts at full blast every 2 or 3 minutes when idle or when opening an IE window or any application.

 

Jordi32,

Looks like I might be correct when I said that the FAN settings are integrated into Toshiba's Power Management software. Here's Hole423's post with his power management settings. I believe if the system was running off XP's built-in Power Management s/w, it may run a bit better. Otherwise, you may just want to tinker with the Toshiba settings.

Venombite,

I tried with the XP power saving settings (both Always ON and laptop/desktop settings) but the fan was almost always on in both settings.

Thank you, Venombite.

Best regards,

Jordi

 

But was that tried after the Toshiba software was removed or while it was still installed? If it was still installed, it wouldn't matter what settings you had for the XP settings, it will still base everythong off the Toshiba software.

Jordi and others......

Here's some info directly from Toshiba about power management..........

I hope that monster link comes through! If not, try this one...

Yordi, i have read in this topic that u have changed your M35 because of the fan noice.I want to ask u how is your fun's behaviour now. My fan kicks in every 2-5 depending on the cpu speed of toshiba power manager. Is this normal? Also the fan's noice is noticeale and annoying. Is there any way to reduce that noice or make the fan not kicks in so often?

Thanks in advance

 

The fans turns on more when you put more stress on the CPU. If you're playing games, or doing other things that utilizes the CPU more, this will cause the CPU to heat up more and the fan to turn on more often to keep it cool. There's no real way to slow down your fan, other than dropping the CPU speed or going on battery. By switching to a slower CPU speed, the CPU runs cooler and therefore the fan doesn't trun on as much. But dropping the CPU speed totally eliminates the reason why you bought a faster/more powerful CPU. If you're trying to muffle the noise, don't bother, blocking the air vents will only cause your system to overheat and possibly die. You can try getting the fan replaced if it's making a bad sound, but Toshiba normally doesn't replace parts unless there's a problem.

Hi Jordi..I dont know if you still have this particular machine, but just an update. I & a friend of mine, have the same laptop and the fan noise is part of the package. I used to get irritated but am yet to find a way around it (do update in case you managed that!). But I am positive that it is not a problem with the machine...it just is an over-zealous fan, that's all. Both our notebooks are over a year old, and both are yet to crash..no HDD failures either. I just take reprieve in the fact that atleast my processor is always chilled out!
Hope this helps!

 

jordi32, switch back to the Toshiba power saver utility instead of letting windows control the power management. Toshibas power management lets you set different cooling schemes. to be precise, there are 3. Battery concious, intermediate, and high performance.

On all of these settings the M35 will NOT have the fan on the entire time. On the battery concious setting the fan will turn on only every once and a while, where as on the high performance setting it will be on quite a bit more but will never reach a high speed unless the cpu is under full load.

If turning on the Toshiba Power Saver and setting it as I have suggested does not help, its likely that something is wrong with the motherboards fan control circuit or the CPU's internal thermal sensor.
