Get the most out of your PC cooling with these BIOS tweaks

The higher the revolutions per minute (RPM) a fan spins at, the more noise is generated. Add seven more fans into the mix, and it can quickly get out of hand. This is why modern fans inside PCs are all controlled by PWM headers on the motherboard. Pulse width modulation enables finer control over how much power is supplied to the fan and how fast the motor spins at any given time. Most UEFI BIOS solutions for motherboards will allow you to take this a step further and fine-tune default fan curves, letting you set how fast each fan spins at for various temperature readings.
