Noctua Heatsinks Editorial Review
Noctua NH-D9DX i4 3U is a premium CPU cooler for Intel Xeon LGA20xx and supports LGA 2011, LGA 2011-3, and LGA 2066 sockets. The product works with the old LGA 1356 and LGA 1366 sockets too. The metal clips needed to install a second fan come with the cooler, so if you want a second fan you only need to buy the fan itself. The base and heat-pipes are nickel plated, making it safe to use liquid metal thermal interface material on the cooler. The cooler comes with thermal paste, and one unit of thermal paste allowed the installation of two coolers. The Cooler keeps the CPU cool at full speed, and full load. One of the coolers even keeps the CPU cooler than a water cooler and is a great, inexpensive replacement for older PCs. The only downside to the product is that it covers one of the user's DIMM slots. However, the user did not face difficulties due to this as they were not using the slot.
