Too hot to handle

In 2008 I bought my laptop, to be precise, a HP DV7 1010ed, with 1800Mhz. dual-core AMD Athlon. Since the beginning I had this problem with overheating, although an average Windows user would blame it on Windows Vista. Because of this overheating the processor throttles down which makes the laptop very slow. An average Windows user might not notice, but as a Linux user I can see it's almost continuously in low frequency mode.

Even worse, Linux doesn't install this frequency scaler risking the laptop to be overheating and forcely shutdown by hardware. Unfortunately the €120,- battery get damaged by such a hardware shutdown, which is in my opinion a design-fault as well.

another cause for the overheating is that I have smoked a lot while using the laptop, so the internal are covered with a layer of tar and nicotine. To clean the fan and the heatsink I have to entirely disassemble the laptop, which in my opinion is another design-fault.

By emerging and configuring cpufreqd I can avoid most, but not all hardware shutdowns. The in-kernel frequency governors throttle down based on load, but with cpufreqd I can make it throttle down on high temperature.

Without additionally cooling in an laptoppad it's impossible to use processor-intensive application like compiling or even programming in Netbeans.

Lately something went wrong with installing the kernel modules resulting in a situation that I could only repair it by recompiling the kernel. Without the modules needed for frequency scaling this was impossible, so in the end I got the kernel recompiled in a chroot environment from the Gentoo install disk.

But what's the use of a fast laptop if most of the time it runs at half speed because of the overheating?
