Noctua is renowned for producing some of the finest CPU cooling solutions. So, no wonder we’ve got another Noctua Processor cooler here. This one has a low profile design that is suitable for the construction of a small form factor. This will allow you to create a smaller PC without compromising on efficiency.

A single 92 mm fan comes with the cooler, which is enough to keep the 8600K cool even if you have overclocked it a bit. With this CPU cooler, you should have no problems with RAM clearance. A noise adapter that regulates the fan speed and reduces the noise also comes with the cooler. This cooler is perfect because what you’re looking for is silent processing.

Performance-wise, you get decent cooling performance for the size, but there are better coolers if you use a normal-sized PC. SFX builds can take advantage of this cooler’s cooling performance, make sure the overall system is adequately ventilated, and there should be no significant problems.

The sheer magnitude of airflow and static pressure, which Noctua was able to pull out of this 14 mm thick 92 mm fan, is what impresses me even more. I know that most of you looked at that fan and figured it couldn’t really do anything; it was just too little. Well, Noctua indeed went to work with this latest addition to their fan arsenal.

One thing is the shape of the blades, but each of them has grooves cut into them, and even the textured finish of the individual blades has its advantages. If you’re not really strapped down for space above this cooler, with the supplied hardware, you still have the option to install a 25 mm thick fan and grab back a few more degrees as well.

I am also very pleased with the results it delivered, even with the TDP limitations of the NH-L9i. The installation should be almost painless if you’re building a new PC. However, if you mount this on a pre-built device, the motherboard will have to be removed. To mount this cooler, you need access to the back of the motherboard.

  • Low profile cooler design
  • Great option for small form factor PC builds
  • Controller is included
  • Easy installation process
  • Fan aesthetics can be improved
  • No RGBs

The most popular and one of the lower budget CPU coolers around is the Cooler Master Hyper 212 EVO. Both the AMD and Intel CPU sockets are supported by the cooler. Using the AM4 bracket (RR-ACCY-AM4B-R1), for which you have to contact Cooler Master USA, this CPU Cooler also supports the new AMD AM4 Socket.

For better transfer and dissipation of heat, this CPU cooler comes with 4 copper heat pipes that are in direct contact with the processor and each other. It is called CDC (Continuous Direct Contact) technology by Cooler Master. It comes with a quiet 120 mm fan that does a fantastic job of maintaining the CPU temperature well below dangerous levels even during CPU load.

It has a dual fan configuration, which means that if you want some extra cooling efficiency, you can also add another 120 mm fan. For certain mini-ITX or mini-tower cases, the cooler is slightly bigger at 159 mm, so make sure it fits in your device case before purchasing it.

If you’ve not done it before, the installation of this cooler can be complicated. Although as long as you carefully implement the directions, installing this cooler shouldn’t be a problem. You might have to remove the motherboard to mount the backplates if you’re installing this on an already installed device.
