- “It looked nice but, crucially, removing a fan from the case meant it was going to be very quiet.” (ZM-NB47J)

Zalman Silent Motherboard Heatsinks
 | ZM-NBF47 Northbridge Flower Heatsink [47 in stock]  (1 customer review) | £5.10 (£6.12 inc. VAT) |
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 a ZM-NB47J 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.

I know that Zalman products usually are of an exceptional, state of the art quality. I personally use a lot of them and usually they do their job better than you would expect them to do.
About the Zalman ZM-NBF47 Northbridge Flower Heatsink.
I have spent two hours attempting to fit the nut into the groove ... frustratingly, the groove is too small to comfortably 'accommodate' the nut. It really p***** me o**. As an engineer I don't usually make the rule out of one incident so let's hope that I won't spend my entire evening thinking 'Why the h*** did Zalman not make the groove to be 0.2mm bigger?'.
