Collection: Cryptominer and Power Supply PSU Cooling fans

Q: How do I know which fan size and connector my miner uses?

Open the miner and check the existing fan: the dimensions are printed on the housing (e.g. 12038 = 120x120x38mm) and the connector pinout (4-pin square ATX is common for newer Antminer; 6-pin linear KF2510 for many Whatsminer models). If unsure, send a photo of the failed fan and we'll match the replacement.

Q: Can I use a higher-RPM fan as a replacement to improve cooling?

Sometimes, but be careful: ASIC firmware monitors fan tachometer signals and shuts down on out-of-range readings. Stick to fans within 10-15% of the original RPM unless you're also installing a fan speed simulator to spoof the signal.

Cooling Fans for Crypto Miners — Complete Selection for ASIC Hardware

Cooling failure is the #1 cause of crypto miner downtime. When a fan seizes, slows down, or starts making bearing noise, the ASIC chips heat up within minutes and the miner throttles or shuts down to protect itself. This collection brings together every cooling fan category we stock for crypto mining hardware — from the 12cm and 14cm hashboard fans that move air across the ASIC chips, to the 40mm and 60mm PSU fans that keep your power supply running cool, plus quiet silencer blowers for home setups and large-format negative pressure fans for mining farm ventilation.

Choose the right fan for your repair

Fans for crypto miners fall into four categories, each with very different specifications. Picking the wrong one is the most common buyer mistake :

Miner cooling fans (12cm / 14cm) — high-static-pressure axial fans that push air through the hashboard heatsinks. Antminer S19 / S21 typically uses 12cm 4-pin or 14cm 6-pin ; Whatsminer M30 / M50 / M60 uses 14cm 6-pin. Browse ASIC cooling fans →
PSU cooling fans (40mm / 60mm / 80mm) — smaller form factors mounted inside the power supply enclosure (APW12, APW17, P221B, AP280, G1240, etc.). Different connector pinouts depending on PSU model. Browse PSU cooling fans →
Silent miner blowers and silencers — for home mining where noise is a concern. Replace the standard high-RPM fans with copper-motor turbines that cut noise by 20-30 dB. Browse silent miner blowers →
Mining farm negative pressure fans (800mm / 900mm / 1000mm / 1100mm / 1220mm) — industrial wall-mount fans for full-room ventilation in large mining operations. Browse mining farm fans →

Hydro and immersion cooling alternative

If you operate Antminer hydro, Whatsminer M63 hydro, or any miner converted to immersion cooling, fans become irrelevant — you need cooling plates, quick connectors, and fan simulators instead. Browse hydro & immersion cooling equipment →
