Cooling Fan for Antminer Bitmain 7500RPM Dual Ball Bearing 4-pin Connector, 120x120x3.8mm / 280CFM T15, S11, S15,DR5 S9i, S9j, S9, S7 V9, T9, A3, D3, L3+, L3++, E3, Z9, Z9 Mini. Also for GPU Miners

These fans are the only ones I use on my L3+s. Something to keep in mind, these fans are 5A, which is a lot power. You run the risk of damaging your control board if these fans run at high RPMs for a long time. You may want to use the stock fan, the one that runs at ~2.7A. Only because it fits doesn't mean it's a direct replacement.

We ordered 8 units to test on Antminer S9 and T17. The fans are incomparable with the Antminers and caused them to crash/reset because of the power requirements (5.0 amp). Antminers are NOT designed to power these high current draw fans. The maximum rpm that was achieved was 4860 rpm at 100% fan speed which causes the Antminer to reset due to a fan speed error. The factory fan is 1.85 amps at 6000 or 6500 rpm which these do not do. Expensive lesson learned

moves air like no other

I bought 2 of these fans to use on my CPU cooler (not a miner of any sort) and good golly are these things powerful as all heck. here is my comparisonstock fans:Idle temp @ ~35game temp @ ~50max load simulation temp @ ~80these super fans:idle temp @ ~30game temp @ ~44max load simulation temp @ ~73worth the money for me!(they are loud as heck though but i personally just dont mind that at all)

Bolted right up, connection matched, works, good airflow and spins faster than my old one. Happy with them as I go through fans every 6 months or so these seem a lot better built. Recommend

I ordered 3 of these and one failed within 2 days

Replaced a faulty exhaust fan on a V9 and S9 Antminer. Has been running for over 100 hours and still going strong.

Almost burned down my garage. Do not buy.
