Best 60mm & 40mm Fan for PC Case, Heatsink, 3D Printer [2018 List]

If you are looking for good 60mm and 40mm computer fans for PC cooling, DIY cooling, 3D Printers and cooling other electronic devices then you are at the right place. Smaller 40mm and 60mm fans can have wide range of applications just besides PC cooling. These smaller fans are rarely used for case cooling nowadays because all the computer cases use bigger case fans which are 120mm and 140mm fans. However, they can be used in a PC case for focused cooling or for cooling other components inside it. These fans can be used to cool down the Northbridge or motherboard chipset, NVMe or SATA / M.2 SSDs, VRMs or may be even RAM. You can also use these fans on your passively cooled graphics card or regular graphics card if it has been heating a lot and the factory fitted fan is not performing well.

60mm and 40mm fans are also used for cooling down Server chassis (1U/2U), SFF or Mini-ITX PC, HTPC, Thunderbolt enclosure, eGPU box, Routers, Switches, Smaller CPU heatsinks, Consoles (PS4 / Xbox etc.), Inverters, Switches, 3D Printers, NAS server / RAID enclosure, DIY Projects, DVR / NVR systems, Raspberry Pi 3, Battery charger and other electronic devices.  So, here I am going to list down the best 60mm and 40mm fans for use in various devices for providing excellent cooling performance. Moreover, these fans also serve as better replacement fans in devices and appliances that use 40mm / 60mm fans for cooling.

Noctua NF-A4x10 FLX Fan

Noctua makes one of the best computer fans in the world and here we have Noctua NF-A4x10 FLX, which is premium 40mm fan. I think this is the best 40mm fan that you can buy for PC or cooling other components or devices. It shares the same premium features that you can find in the bigger fans from Noctua (80mm, 120mm, 140mm etc.). The fan comes with Noctua proprietary SSO2 bearing that is known for longer lifespan, higher performance and silent operation. The fan speed is 4500 RPM and it uses 3-pin connector. The fan is on the slimmer side and is only 10mm in thickness. This allows it to be compatible with most of the components and can be used for variety of purposes.
