well, giving my PC a blowjob took care of the heating problem. but it still makes these fan noices from time to time. if I tilt it upside down, it stops. but I can't work like that. too anal.  |

| Well shit, all the heating problems described by people here with their laptops is enough to put me off buying ANY laptop, and I was considering doing so in the near future. But wtf? Laptops are designed for a bit of light browsing for some hours and that's it? My old PPC G4 desktop has hacked it continuously open for up until 67 days, it's own fan provides all the cooling it's ever required. I'd be pretty pissed putting up with cooling problems described so far, seems like a desktop is a much better solution. |

I don’t think that all laptops have cooling problems, or at least mine has none. Of course laptops have a worse cooling that desktops, because of the limited space for fans and vents, but I do not consider that a problem. Regulating your CPU speed really helps a lot to keep the temperatures low (and also saves energy).
Currently the temperature of my processors is 56ºC, both running with 1GHz. When I do something that requires more resources, the speed is adjusted to 1.3, 1.6, or 2GHz. When running at 2GHz for half an hour or longer cooling becomes somewhat problematic, as the temperature increases up to 95ºC, but it never reaches critical values. |

Interesting, I didn't know about speed regulation to keep a laptop cooler. How do you determine exactly when you need greater speed? So far I've always been happy with a desktop's performance, regardless of make. |

I am using powernowd for it. It runs in userspace and because of that has less options than doing the same on lower levels, but for normal use of your computer it is fine. When the CPU load rises above 80%, or sinks below 20% the speed is increased or decreased. Usually the CPU load is so small that both processors run at 1GHz, which is the lowest speed possible with my processors. |

| Interesting point there, I'll definitely look for something along those lines if I actually pluck for a laptop. |

if you say you have no cooler issues, termal paste applied correctly and also no improper airflow, it's just because the processor is crappy and the cooling system doesn't handle it 
is it an AMD or Intel ? ...
having a lot of Fujitsu Siemens Lifebooks returning to service with this issue... Solution: get a CPU that doesn't reach so high temp. or get a better cooling system
there are new cooling technologies, like "ionic cooling", read more here:
http://www.technologyreview.com/biotech/19285/?a=f
other things you could do
a. get a cooling pad
b. get arctic silver, it's a thermal compound made of 99.9% pure silver
www.arcticsilver.com
c. undervoltage the CPU, you could make the CPU multipliers run at a lower voltage (lower it by a max of 0,2 V ). You have to consider that it doesn't work with all CPU brands and it may cause system instability.
or you could use liquid nitrogen, might help ( PS: only a temporary solution ) |
