3. Watercool Heatkiller NSB Rev 3.0 LT
The HEATKILLER® CPU Rev3.0 LT sets new standards in performance, quality and ease of assembly. The development of the new high-end processor cooler was consistently aligned to the current CPU generations.
A central flow paired with a nozzle plate and an extremely fine cooling geometry give the cooler an excellent cooling performance. The base plate can be geometrically adapted to the heatspreader and thus ensures optimum contact with the CPU. Despite the very complex cooling geometry, the flow resistance is extremely low. For the use of quad processors, the cooler has a pluggable distributor plate, so that the individual CPU cores are flowed in parallel.
A modular design allows the HEATKILLER® to be easily opened, and it is possible to change to a different mounting system at any time and to do so in just a few simple steps. Separately available brackets and spare parts guarantee trouble-free operation, even after several years.
The cooling geometry is made of electrolytic copper, the upper part of which is made of high-quality POM. Stainless steel was used for the brackets and applications.

5. Watercool Heatkiller NSB Rev 3.0 Nickel
The HEATKILLER® NSB 3.0 Series combines performance and maximum compatibility. The mainboard coolers are designed to ensure compatibility with a wide range of mainboards. By turning and flipping the bracket, it can be mounted in any position. The scope of delivery includes two brackets, so the cooler can be mounted on all mainboards with a diagonal hole spacing of 43.0 to 79.2mm. The position of the holes is irrelevant, as the cooler can still be aligned horizontally to the board.
The base plate is made of high-purity electrolytic copper and has a very efficient cooling structure, the flow resistance of the cooler is extremely low. Despite the small outer dimensions (39x39mm) the threaded holes (G 1/4 inch) are 22mm apart.
The upper part is made of high-purity copper, the holder and applications are made of ground stainless steel. To prevent the copper from tarnishing, the upper part is sealed with a special clear varnish.
The HEATKILLER® NSB 3.0 can be mounted on the Northbridge and on the Southbridge.
