Linux: Low CPU Clocks on laptop while gaming?

Unfortunately, this was a custom build, and has an extremely bare bios; Pretty much just boot and usb controls. It is a shame really, since the laptop would be a great platform for specific task adaption if it had options for fan control and temperature, etc. Sadly I have not been able to find any such controls.

What bios does it have? Pheonix? Altec? Northstar? Biostar? Insyde/H2O? You can get cracked bios's and flash them to get the full features of the laptop. Even overclocking features from the desktop versions.

Having spent some time in both OS's, the fans appear to run much faster on windows than linux, but I do not seem to have anything that controls them manually on either os, any ideas how to change the rpm on linux?
