Toshiba Satellite M55-S3512 cooling fan?
458626
laptops create a lot more heat then desktop computers.  they need to run the fan alot.  also the fan will run more when you have it plugged in because the power settings are higher.  try changing the power profile. you can reduce power to things like your cpu and monitor, this will slow down the computer a very small amount or make your screen less bright but it will make your battery last alot longer and stop your fan from comming on as much.

i would be checking the cooling fan first.if it is not running thats your overheating problem.not knowing how old your box is?-what version of windows or are you using windows  makes it pretty hard for us to answer.have you overloaded it?have you done a recent defrag-there could be several reasons.

If it's a steady whine, with no fits and starts, it's going to be a fan.  The possibilities are power supply fan, cpu fan, video card fan, and system cooling fan. All of them with the exception of the video card fan, are easily replaceable by a layperson with nothing more than a screwdriver.  Luckily, the video card fans are small and less likely to produce much of a noise, so it's probably one of the other three.

Something must be wrong with it, bring it back to where you got it, and have it checked out, and if that is normal, buy a cooling pad for it (aobut $30).It elevates you laptop off the table, and has fans for circulation, keeps you computer running as cool as possible.

First, make sure the fan inside is working. Second, make sure you have it set on a flat smooth hard surface. Sitting it on your lap or on the floor, the bottom is pressed against the fabric. Also on the four corners on the bottom there should be small pieces attatched to raise it above the surface slightly. Make sure you have them. If not, you can glue small round foam pieces about a centimeter to raise it a little. Also, you can go to Staples or another computer store and buy a item that keeps the computer cool. Explain to the sales assosiate your problem and they should be able to find it for you.

HI, lovely system the XPS400. It doesn't need an extra fan, it comes with two. And even if u find some place to put one, put one at the rear to pull out hot air i.e. an exhaust bcoz that'll automatically work for the cool air to be sucked in.\nHope that helps for more u can check out\nhttp://support.dell.com/support/edocs/systems/xps400/sm/index.htm

Your cpu fan may not be working. You need to replace it before you computer overheats.\n\nThe CPU fans are not expensive, and easy to install. If your computer is a name brand computer, you can usually search the company's website for instruction on how to replace it.\n\nGood luck

there are no liquid cooling systems for laptops..its not compact enough to fit into a laptop...if you are having overheating probs with your laptop then a USB Fan Cooling Mat can help..also make sure you dont cover/smother the fan/s on the rear of the laptop by using it on your bed (for eg)

The cooling fan cycles on and off, and can be quite noisy when it is running.  If the noise is on sometimes and off sometimes, that's probably it.

the cpu fan has a sensor in it that tells the motherboard what speed the fan is spinning. the sensor can go bad and the fan will still work. your going to need to replace the fan. Most motherboards won't let the computer boot up with a 0 fan speed

I have a Toshiba Satellite A70/75 that was doing the same thing that yours is doing.  I had to send it off for warranty repair.  It was shutting down as you described.  If I tried turning it back on too soon after it shut off it would not take long before it would shut off again.  If I waited a while then it would take a while before it would shut off.  It would just shut off out of the blue without a Windows is shutting down screen even showing up.  Just poof.  \n\nI read where other Satellite model laptops had the issue as well.  They had to replace the heatsink and clean it out.

Try this site:\nwww.almico.com/speedfan.php\nIt offers a software that can monitor and change your CPU's fan speed, to hopefully reduce noise. I don't know how well it works. It does say, "This program is aimed to the power user" (as in, it's not for basic computer users, since they might accidentally blow the thing up?), but from your questions, it seems like you are pretty knowledgeable. You might try it.

This fan is a big problem alright. I got the A8NE-Premium just so I wouldn't have to deal with that fan (has a heatpipe instead). I heard ASUS has been good about replacing the fan with a supposedly improved model. Call and tell them that it failed and you would like another one. If that still is annoying there are some third party cooling solutions...or sell your A8NE on ebay and get the sli-premium! It is a pricey one however.\nThis forum discussed the problem in some detail:\nhttp://forums.anandtech.com/messageview.cfm?catid=29&threadid=1800554
