Anycubic replacement fans for Kobra S1 and 3
Anycubic sells each fan for its Kobra printers separately: hotend, part cooling, mainboard and duct, depending on the model. The hotend fan matters most for avoiding clogs: if it slows down or stops, heat reaches the filament too early and the nozzle jams; the part-cooling fan affects overhangs, bridges and fine detail. Pick the one that failed on your printer, as they're not interchangeable.
- There are hotend, part-cooling, mainboard and duct fans, each with its own variant.
- For the Kobra S1 and Kobra 3 (the 3 V2 and Combo versions too); the page opens on the Kobra S1 hotend fan.
- The Kobra 3 part-cooling fan is a 24 V 5020 blower at 7000 rpm, according to the spec sheet.
- To find the culprit, see which one doesn't spin or makes noise with the printer on and the hotend hot; the part-cooling fan only starts when printing.
- If the hotend fan fails, stop printing until you replace it: without it, mid-print clogs follow.

How to choose the right one
Choose your model and the exact fan that failed in the shop: hotend, part-cooling, mainboard and duct fans can't be swapped for each other. Check the old fan's connector before removing it.
How we choose products
usi3d shows products from other shops for their compatibility with your printer, because they help with a fault, because they ship to Spain and because the shop is trustworthy. The commission does not decide what we show or in what order.
