Why Does My Computer Get So Hot?

Sun May 29, 2005 11:03 am

It's a laptop, Dell Inspiron 1100. Out of 650 megs of memory, it is using about 30%. 6% of the hard drive is empty. On average the CPU is at 20% or less, except when the fan turns on it spikes to about 90% and sits there for about a few minutes.

Right now, all I got is the internet running, that's it, 15 processes. The fan is medium now, but the bottom is way hot. I could keep food warm with it.

I can't place it on anything, the fan runs on high almost all the time, damn loud. I was on the floor one time and held up the vents with an old cassette box, it melted a bit of the plastic.    These days I do unconventional crap like sit the thing in a table fan's face and set it for low. That way it cools it a bit. A bit, fan still runs on high, in fact according to Dell diagnostics CD, the fan speed failed by being too fast; regularly at 6300 rpm. I think the motor expells just enough heat to cool itself down.

I do AdAware scans twice a day, I had to uninstall the Norton Antivirus because it took up too much memory, it made my machine run hotter.

Edit: oh yeah, I did think of laptop coolers. Upon investigation, i found that those devices suck heat from below, then out and away. My one fan suck from below and blows to the back. Though it may cool the memory, I'd end up choking the cpu fan.

I do not have the funds for a new computer, I want a desktop, maybe I do not have to deal with this. It bugs cuz I think this thing wil just die one day when I'm unprepared. I'm considering backing up everything now...but I know I'll loose things like the playcount in the windows media player, I need that.

Blow the fans out with some canned air . . . same with the vents on the case. My Toshiba gets warm also, not hot enough cook a meal, but part of the problem is dust collecting inside the case. . . . canned air will help. My fans never run constantly on high however . . . Don't crack the case on a laptop . . . might void your warranty . . .

The same damn thing happens to my HP craptop. The fan runs loudly and the computer gets so hot. And the weather is pretty cold (14 degrees C)...and I only have iTunes and the Internet running.

My CPU runs at 100% most of the time (I have no idea what the hell is using it up!) and I can't play DVDs because the memory is so full, the DVD runs in slow motion...

AND..I can't listen to music or anything because the damn fan is so loud..arghhh  irked

Same problem here laptop Compaq Presario 2500 (Keep away from any Compaq products!!!!) I have a base with en extra fan but during hot days it just goes vmmmmmmmmmm....

A solution that i have came up with is to use the vacuum cleaner on regular basis to collect the dust from every reachable place.

I've had 2 Compaq Presario's. Never had a problem with them. My current (X1000) is so quiet, you can just barely hear it and it doesn't even get warm, you can leave it on your lap for hours and you don't even notice. Guess I got lucky.

All of my info is pertinent to Windows XP Professional SP2...should apply to anything similar.

Go in and uninstall the programs on your system that you don't use. Only uninstall a program by going to:

Start > Settings > Control Panel > Add or Remove Programs

Check your power settings on the control panel as well. If you have your system set to never sleep or hybernate, it will run constantly. I have mine that way because it is never unplugged.

Also go to:

Start > Settings > Control Panel > Administrative Tools > Event Viewer

That will show you error logs, security logs etc on your system and tell you where they're coming from.

I'd also organize some disk space, and although the NTFS file system doesn't need it, I speed up disk access by running disk defragmenter anyway. The disk defragmenter tool is under:

Start > Programs > Accessories > System Tools > Disk Defragmenter

Also, keep your dekstop free of too much stuff.

Some of those tips should help.

Laptop fans shouldn't run constantly, unless you're running a serious program, like MS Flight Simulator. I manage mine with I8Kfangui, which was created for Dell's 8000-series laptops. It allows you to set the temperatures and speeds at which the fans activate (btw, the fastest mine go is about 9000 rpm). My computer tops out at about 62-63C, when the processor's running at 100%. Otherwise, it's between 45-52C or so.

I highly recommend it, although it didn't work with my sister's Dell 5100. At home right now (my mother has my sister's computer while she's in Europe), it's on a pair of laptop risers, for more comfortable viewing. Despite getting it off the desk, it doesn't run any cooler (but it already runs fairly coolly, cooler than yours).

MD-90, I haven't shut off this laptop in 12 days, runs 24/7. It's not laptop, it's capability of the machine.

I don't have a docking station or anything fancy . . .a simple Toshiba laptop. It has two fans, both are clean now, as you can see form above, and I have never had an overheating problem. Prior to their cleaning they were humming a bit . . .

I'm no computer guru, but I would surmise, with today's technology and advancements, this isn't a problem. It's hooked to a DSL line, a printer and an external hard drive.

Thanks for the link, and I'm definitely going to check this out . . . anything to make the machine better, cooler, faster, etc.

Oh yeah. My Dell 8200 is probably more stressed than most, because I run Seti@home as my screensaver. For three years now, it's been running right along, processing data units, and it runs the processor at 100% when it's computing. So the computer heats up to about 63C. Never had a problem with it, although I don't like how the stock Dell bios will let the computer get up into the 70-75C range before going to high on both fans. I think that's too hot.

But my 8200 has never had an overheating problem.

Never had problem with my wonderful Compaq Presario Labtop, even in Southern India with 38°C.

But I use to bring it up, using the two backside feet, so that my laptop does not remain flattened on my desk.

If enough air can circulate even under your laptop maybe its overheating problem will be solved.

Cheers. Kilavoud.

Quoting MD-90 (Reply 7):

I'm gonna' hang out with MD-90 on this one. I'm on a 6 year-old Sony PCG-F series that's been through the ringer (dumped a whole beer in it, dropped it from walking/carrying height about 5 times, left it in my car on 100+ / -10 degree F days, Upgraded from a Win98 factory install to NT4 workstation, to 2000 pro, to XP pro, etc.).

My suggestion would be when you hear that fan fire up for too long, to right-click on your taskbar, go to properties, and sort by CPU. Look for weird stuff that's hogging CPU time. If in doubt as to what a process is, jump on Google and drop (example) "crazyhogcputime.exe" into a search. Sometimes it'll come back with some nasty process that might have been backdoored on your machine.

If there's anything that I can do to help, let me know. I do everything from high-end carrier class optical routing/switching down to the desktop.

Cheers!

All that heat from the processor has to go somewhere !

Just stuck my hand under the Toshiba laptop I've got at work. Very warm and it's raised in a docking station ! The Dell I had prior to this was equally warm. I'd never use this thing directly in my lap unless I'd like to slowly cook myself.

At home we have two PCs in the study and an iMac is soon to join these. That room has the heating vent turned off as there's at least about 100w+ of heat coming out of all those machines, screens, etc. The room is comfortable with these expensive PC heaters running and it's almost winter here in Melbourne.
By the way, is there anyone on board who knows how to fly a plane?
