CR12B6020M 60mm 12V Cooling Fan for iPollo G1 Mini PSU Replacement
The CR12B6020M is a 60mm 12V DC cooling fan purpose-built as the replacement PSU fan for the iPollo G1 Mini crypto miner power supply. When the original PSU fan starts to grind, stall or run hot, this drop-in spare restores stable airflow inside the PSU enclosure and prevents the cascade of thermal shutdowns that ultimately fries MOSFETs and electrolytic capacitors.
Built around a dual ball-bearing assembly, the CR12B6020M is rated for the continuous duty cycle that a 24/7 ASIC PSU demands.

Where the CR12B6020M fits inside the iPollo G1 Mini
Inside the iPollo G1 Mini PSU, this 60mm fan is the small intake/exhaust fan responsible for cooling the rectifier stage, the switching transistors and the secondary-side filtering capacitors. A weak or seized PSU fan is the single most common root cause of premature PSU failure on home-tier ASIC miners: temperatures climb, electrolytic caps dry out, and shortly after the unit either throttles, stops sending DC to the hashboard or trips its internal protection.
When to replace the PSU fan in your miner
Even a healthy 60mm sleeve fan only lasts a few thousand hours under continuous mining load. Dual ball-bearing fans like the CR12B6020M are the preferred upgrade because their service life is roughly an order of magnitude higher and they tolerate higher ambient temperatures without bearing whine. Replace at the first sign of rattling, irregular RPM or visible dust packing — not after the PSU shuts down.
Common failure symptoms
- PSU fan stalled, rattling or rotating intermittently
- iPollo G1 Mini shuts down under load due to PSU over-temperature
- Burning / electrolytic smell from the PSU vents
- PSU output voltage drift or hashboard losing power randomly
- Visible dust caked into fan blades after months of duty
Frequently asked questions
Is the CR12B6020M a direct drop-in for the iPollo G1 Mini PSU fan?
Yes. It matches the original 60mm form factor, 12V supply and 4-pin connector used in the iPollo G1 Mini PSU.
Can I use it as a generic 60mm 12V fan elsewhere in a miner?
Mechanically yes, anywhere a 60×60×(typical)mm 12V DC fan is required, provided the host accepts the 4-pin pinout and the current draw is within range.
Does the fan come with a tachometer (RPM) signal?
The fan ships with a 4-pin interface; for exact pin assignment in your specific application, see the specifications panel and contact us for confirmation.
Do you ship single units or wholesale quantities?
Both. Email us for volume pricing on PSU repair-shop quantities.
