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 a 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 maybe 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, FLEX ATX Power Supply, 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.

40mm Fans 12V
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 a premium 40mm fan. I think this is the best 40mm fan that you can buy for a 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 a longer lifespan, higher performance, and silent operation. The fan speed is 4500 RPM and it uses a 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 a variety of purposes.
This fan generates airflow of 4.82 CFM and a good amount of static pressure at 1.78 mm H2O. It is also a very quiet fan and has a maximum noise rating of 17.9 dBA. It does have anti-vibration pads on the corners to minimize noise and vibrations. Other features include Flow Acceleration Channels, AAO frame, Stepped Inlet Design, Inner Surface Microstructures, Smooth Commutation Drive 2, Low-Noise Adaptor (L.N.A.), 3 to 2-pin Adaptor and Polarity Protection, OmniJoin Adaptor Set.
This high-quality 40mm fan can be used in computers or for cooing down components, northbridge, graphics cards, or as a replacement fan for 3D Printers, NVR, DVR, NAS, or other devices where a 40mm fan is used. There is also a PWM variant (4-Pin) of this fan that spins at speed in the range of 1000 to 5000 RPM and offers a bit more airflow and static pressure, but with a slightly higher noise level. Both these 40mm fans come with all the required connectors, cables, and adapters so that they can be connected to any device or fan header without any issue. The price of both these fans is almost equal and you can check out both of these models from the links given below. Highly Recommended by me.
