Zalman NB47J Northbridge Heatsink

ZM-NB47J does not require a fan, thus does not need to be powered, and does not generate noise or vibration.
The Northbridge chipset can be cooled to an optimal temperature without generation of noise.


Zalman Tech provides Noise Prevention (NP) power supplies, CPU coolers, and case fans, as well as fan-less Northbridge coolers and VGA card coolers to provide you stable performance and a noiseless environment.
