Active cooling is under control of ACPI, typically not exposed to non-windows 
operating systems:
hw.acpi.thermal.tz0.active: -1

Value other then -1 you might actually be able to change it.

But...your best 15USD spent will be a laptop cooling pad, best one powered by 
the USB port. Some lappies just can't be fixed with fanspeed, because of bad 
design and a cooling pad will take at least 5C off.
