Need some serious spot cooling for your 3D printer or electronics project?

This 2-pack of 40mm blower fans is a great deal.

They're the 4020 size, meaning 40mm x 40mm x 20mm, and they push a decent amount of air—up to 3.12 CFM at a max speed of 5500 RPM (plus or minus 10%).

You can choose between 5V, 12V, or 24V versions to match your setup.

They come with a 2-pin XH2.54 connector, making them easy to wire up.

Plus, the pack includes mounting screws and nuts, so you have everything you need to install them.

They have sleeve bearings, which are quiet and reliable.

These are unbranded, generic fans, but they're new and ready to cool down your hot ends, electronics enclosures, or whatever needs a focused stream of air.

Great for DIY projects, upgrades, or replacements.

Grab this 2-pack and keep your gear cool!
