1. ZM-NB32K does not require a fan, thus does not need to be powered, and does not generate noise or vibration.
2. The Northbridge chipset can be cooled to an optimal temperature without generation of noise.
3. You can adjust the direction while in installation. So you can prevent the interference with CPU Coolers and other components.
1. The ZM-NBF47 does not need electrical power, for it is a fanless Northbridge cooler that operates without noise or vibration.
2. It cools the Northbridge chipset to its optimal temperature in absolute silence.
