Aquarium Clip-On Cooling Fan

The PAIZOO PZBS-2 is a USB-powered clip-on cooler designed for freshwater and saltwater tanks. It targets hobbyists who need a compact way to lower water temperature for species such as axolotls without installing a full chiller unit. The fan clamps onto rimmed glass up to 26 mm thick and draws 6.4 W from any standard USB port.

Three-Speed Brushless Motor Thermals

Dual turbo fans use a brushless inrunner motor with double-cap mute bearings to move air across the water surface. Three push-button modes — soft, standard and high — let the user balance airflow against noise. Soft mode runs quieter for evening use while high mode maximises evaporative cooling when temperatures spike.

Adjustable Mount With Long Cable

The clamp opens wide enough for tank walls up to 26 mm and requires no tools to fit. A 45-degree adjustable head directs airflow where it is most effective. A 150 cm USB cable reaches most power sources without extension leads, and the ABS plastic housing weighs 0.431 kg for stable mounting.

Questions about this item

How do I clip the PZBS-2 onto a tank rim that is close to 26 mm thick without stripping the screw?

Open the clamp fully, seat the jaws squarely on the rim, then tighten the thumb screw by hand only — the wide clip grips up to 26 mm and over-torquing strips the plastic threads.

When will the brushless inrunner motor or the double-cap mute bearings need service or replacement?

The brushless inrunner has no brushes to wear out; the sealed double-cap mute bearings are lubricated for life, so no scheduled motor or bearing replacement is required.

At what point does the 6.4 W USB power limit stop the fan from cooling further during a long hot spell?

The 6.4 W draw caps airflow at the high-speed setting; once ambient heat load exceeds what that fixed maximum airflow can remove, temperature will stop dropping.
