Kesv, can you name some of those cheap aftermarket heatsinks that are worse than the stock ones. Pretty much all that are cheaper than 15€ or so are worse than the heatsink included in the boxed CPU. That same 15€ happens to often be the price difference between the boxed and bulk CPUs. So as a...

There are two ways of lowering a fan's speed. Voltage regulation and pulse width modulation. Voltage regulation just drops the voltage fed to the motor. Pulse width modulation (PWM) uses constant voltage, but turns the power on and off in rapid 'pulses' effectively reducing the speed. You can purcha...
