Install Notes:

Fuma 2 Rev. B

The Scythe Fuma 2 Rev. B comes with a mounting system that offers compatibility with a wide variety of Intel and AMD sockets. The installation process is relatively straightforward, thanks to the detailed instructions and high-quality components provided. This cooler employs a similar method to the Noctua installation, but with a slight alteration in the male and female connectors on the cooler's mounting system. This modification allows for easy installation and removal of the cooler. However, to ensure optimal cooling performance, it's essential to carefully follow the instructions and achieve proper mounting.

AK620

The AK620 has DeepCool's more modern installation designs as of 2023, which has more components than most for an easy install. The backplates are held down by single hand screwed nuts that also serve to hold the mount from the other side. This makes it easy to place the backplate correctly during the installation. The remaining portion of the install is similar to that of Noctua's typical installation, which makes it easy, but also can make the uninstallation challenging if the thermal paste sticks well to the CPU.

Cooling Performance:

The performance of the Scythe Fuma 2 Rev. B is exceptional due to its six heat pipes that efficiently transfer heat away from the CPU and into the large fin arrays of the heatsinks. It is suitable for a wide range of processors, including moderate to low level TDPs. The cooler may not be suitable for high levels of overclocking but it is a popular choice among enthusiasts for mainstream CPUs.

AK620

The AK620 delivers remarkable performance due to its six heat pipes that effectively move heat from the CPU to the extensive fin array on the heatsink. It is compatible with a variety of processors, even high-end ones with high TDPs. This cooler can handle challenging workloads and extensive overclocking, making it an appealing cooling option. For those seeking Noctua-like performance without breaking the bank, the AK620 is a strong contender.

Noise Performance:
