Laptop overheating... is this normal?

I have a nice Dell Inspiron 5150, with a P4 3.06GHz processor. I find that as soon as I do something a little CPU intensive, the fan gets annoyingly loud. And if I start playing some game (say a nesticle rom), it gets even louder, and performance starts to drop slightly... Like keyboard slightly misbehaving, and more glitching... generally seems slower.

Anyway, the other day, I was playing Quake 3, and about 15 minutes into the game, I guess my laptop overheated. It just shut down completely. It was really hot, like I could feel it through the table and everything. After it cooled down, it worked fine and all, but now I'm worried about playing games cause it might overheat like that again.

So the question:

- Does the dell inspiron 5150 just have a crappy cooling system that doesn't properly do its job when running a faster processor, or is there some fault in my system somewhere? I didn't mod it, and one would assume the dell people know what they're doing, to some extent.

- Is there a good/common/cheap way to cool laptops without having to change peripherals?

I haven't had any overheating problems myself, but I do know that Dell laptops are infamous for overheating during intensive tasks like gaming. I've heard good things about i8kfan (http://www.diefer.de/i8kfan/), which is designed to allow you control over how your cooling works and when it kicks in.

As an alternative, I'm looking into an external cooling pad for my laptop-- they are specially designed to increase airflow and allow the laptop to cool off more efficiently. Some of the specific models I am looking at as possibles:

Hmm, controlling my fan might void the warranty, but reading the temperature sounds like it could be useful (or at least interesting). I wonder what temperature it uses as a cutoff point to decide that it's time to shut itself down.

I saw your cooling pad thread, and I think that might be just what I need. And $20 is not so bad I suppose, but I don't know how much these things help. I should prolly contact Dell and see what they have to say about it, beside "buy our own brand" hehe. I hope these things are really efficient at it, and relatively quiet. Maybe I wouldn't have to listen to my fan so much :).

I had a P3 700 Compaq laptop already with a lousy cooler - the CPU area would get literally painful to touch for more than a half a second. I took the thing apart (it was old, so no warranty), and removed the cooling assembly, which is a metal block, with a heatpipe on it, that went to a small radiator assembly with a fan. They of course used a lousy thick thermal pad, which didn't let a whole lot of heat through to the cooling assembly. I couldn't just use ASII on it though, because of the thickness of the thermal pad used - the mounting system left a considerable gap between the cooling block and the CPU, which the thick pad filled in. So I got a sheet of copper, cut a piece to size (a bit bigger than the CPU core), and made a sandwich:
--Heatsink block
--ASII
--Copper sheet
--ASII
--CPU Core

The copper sheet filled in the gap, and the ASII did the thermal transfer. The fan runs less now, because the CPU is cooler. The heatblock also contacts the metal keyboard shield, so it conducts heat away as well, turning a good portion of the laptop into a heatsink.

Long story short - I seem to have outdone Compaq's engineers in designing an effective cooling solution. :)
Don't know if you can do anything like this with yours...sometimes lousy cooling is caused by the manufacturer using cheap solutions, rather than effective ones.
That said, one of those cooling pads could be a good idea too. Modern notebooks do still have to dissipate a lot of heat. And notice something there - they seem to be called "notebooks" now, and not "laptops." Can't keep them on your lap anymore without suffering first-degree burns.


And while I'm here, I'll recommend AGAINST getting this cooler. The fans on mine started to go after about two months. One works fine, one makes a groaning sound, and the other spins at maybe 120rpm.

I am facing a similar problem.... Link

Try I8kfanGUI ... helped me.

I have never had ANY stability issues with my Inspiron 8500 ...
