Zalman Silent Motherboard Heatsinks
Many new motherboards are now supplied with fans on the Northbridge chipset in order to give adequate cooling. These Zalman products take a different but refreshingly simple approach. By using the maximum possible area of the chip surface, and by having an oversize fin design, the motherboard northbridge is cooled safely and without any noise whatsoever. In some cases, the chip will run even cooler than with the noisy manufacturer-supplied HSF, enhancing PC stability.
Features
- Reduces motherboard noise to zero - operates in absolute silence
- Compatible with all motherboards with push-pin holes and hooks around the Northbridge chip
- No fan required
- Reduces dust build up
- Easy to install, may require motherboard removal
- Flower design for maximum performance
Installation considerations
If your existing Northbridge cooler is secured using pushpins going into the motherboard, then the cooler can be removed and this product can be mounted in its place. Sprung pushpins and a tube of thermal compound are provided with the product. Installation is easy, since a clever adjustable mechanism caters for a variety of pushpin locations, and the white thermal compound is spread on the mating surfaces for optimum heat transfer. The ZM-NBF47 can also be secured using push-pin holes, but it is only recommended for the very latest Northbridge chipsets.
If your existing heatsink is secured using hooks, then the ZM-NBF47 is ideal. Just un-hook your current cooler, remove the old thermal paste and add new, attach the ZM-NBF47 and you’re done.
Review
Computer Active
It looked nice but, crucially, removing a fan from the case meant it was going to be very quiet. (Product reviewed: ZM-NB47J)

Customer Reviews
Big, but cools well
I’ve used this as a cooler replacement for a nForce3 250 northbridge. Fitting may be tricky dependent on your motherboard layout. In my case I managed to just fit it avoiding blocking the PCIe graphics card. It can be fitted in various different orientations so some trial and error may be needed. If your existing cooler is held on with push pins you will need to remove the motherboard from the case to detach it.
Once fitted it runs the chipset much cooler, hopefully extending the life of the board.
Difficult
Very good heatsink, but installing it is very difficult. Lowered the temperature on my Gigabyte northbridge by some degrees (can’t remember exactly how many). If you have the time and patience, and need no lower the temperature a little bit this is recommended.
