I feel like my laptop is constantly running hot. It is ok, it stays on and everything during normal use. I can also play CS with no problems, but when I try to play wolfET the machine will play for a very tiny amount and then hard freeze. I end up holding down the pwr button to turn it off. I'm trying to figure out whether it is a heating issue or not. So far the programs I've downloaded to tell me about the temperatures have done a poor job.(Things like showed the temperature of 2 cpus even though I don't have 2 cpus) things like that. I just don't think they have the information about my laptops mainboard and such so the program guesses on stuff...
I'm shit at troubleshooting heating problems as I've never run into them before, suggestions?
Thanx in advance,

Playing games on laptops does tend to cause heat issues because you're stressing many of the components continually.
First try making sure the machine's getting enough ventilation. Sitting it on carpet or another soft surface is bad for it - firstly because you block air vents, and secondly because these surfaces harbour dust that gets sucked into the laptop. Depending on the case design, vents can also get blocked on a firm, flat surface if the laptop has lost one or more of its rubber feet (meaning there's not enough air getting under the laptop). You could try propping the back of the laptop up with a book or something to make sure air can circulate.
If you've had the laptop for a while, it's inevitable that dust will have got into the cooling system. You'll need to get access to the fans and heatsinks (even if it means dismantling part of the laptop - many manufacturers foolishly design their cases without easy access panels for parts that require cleaning), and remove any dust and gunk that has accumulated inside. If you have to remove the heatsink to access it, remember to clean the thermal interface surfaces on the CPU and heatsink and apply a new layer of thermal compound. Cleaning out dust clogs and applying new compound can dramatically improve the amount of heat a laptop's cooling system can dissipate.
Finally, you may just have a laptop with a badly-designed cooling system (it's more common than you might think). Some laptops simply cannot take the stresses of running high-demand applications continously. If you try all the above and still get lockups, you should consider getting a supplemental cooling system, such as one of those tray-like bases that elevate the laptop, act as a heatsink and often have fans in too to help shift hot air away from the laptop as fast as possible. Or you could play with an ordinary desk fan pointing at the vents!

LOL my P4-2600 Notebook always overheated. Then it drops the CPU frequency to 1300. fps dropping below the cellar while making a very high beep sound - nice feature but annoying. an year ago i disassembled the cooling unit, cleaned it and again it worked like charm. I also tried external fans and built spechial cooling devices. For better airflow I also removed the CD-drive. But cleaning did the best result.

protip: if you have an Intel processor with Hyper-Threading, most programs will tell you that you have two CPUs when you do not. This is because you have a CPU that runs processes in a dual-threaded mode, so that no one process can chow down on 100% of your clocktime.

Not a Hyperthreading processor. That's the first thing I thought of when I saw that but that doesn't make sense either because not only do I not have one, even if I did, it measures the heat with the seperate thermometer that is nearby/under the chip and not like one thermometer per core.. that's silly. Anyway, I figured out that it simply must be a problem with the software of wolfET since things like Doom III and counterstrike seem to play fine. WolfET, again, just locks up after a few minutes (and the laptop felt really hot so I thought it was overheating)
Thanks anyway though!! :)

There could easily be two readings for the CPU temperature: one for the core, one for the immediate surroundings, the heatpipes or the heatsink itself. All that having two readings for temperature means is that you've got two temperature sensors.

Normally if a processor gets overheated, the processor will adjust it's speed by changing the multiplier. Example: fsb 133x 14 = 1862mhz = 2500+ xp. If my laptop gets way hot, it will adjust the multiplier to 10 (10*133=1330mhz) Should test your memorychips and videocard in the laptop. (would try to run a diagnostic tool for the memory (http://www.ultimatebootcd.com/)

Well, when are we supposed to be able to do this? I just paid like $200 for a warranty renewal on my machine. Should I send it to Dell to have it checked out?

bad idea. last time someone I know sent a machine to dell to get a hard disk replacement, it came back with some obscure outdated version of netbsd installed on it over a broken windows partition.
