A fan spoofer is a device that tricks your ASIC into thinking its cooling fans are spinning at the correct speed, allowing for the use of more efficient cooling methods without triggering safety shutdowns or error messages.
Great for keeping your warranty in good standing with Bitmain 👍🏻
Please note that you do not need spoofers if you are using 3rd party firmware such as BraiinsOS+, LuxOS, VNISH etc as they all have options to 'disable fans'; spoofers are only required if running stock Bitmain OS
We offer these in three options:
1️⃣ IceRiver 2in1 — these pesky manufacturers have their fan pins in weird spots, so you will need 2x of these as shown in the picture to connect to their respective control boards
2️⃣ Antminer KS3 — coverage for all four 4 Pin PWM fan headers on the Antminer KS3 control boards
3️⃣ Antminer 4in1 for KS5/Pro — tested and working with the Antminer KS5, the standard 4in1 spoofers (1️⃣ ) won't work after a recent firmware update from Bitmain.
Hardware includes 60 day warranty from date of shipment
Enjoy efficient and stress-free mining with our fan spoofers 👍🏻

These filters are working much better than what I was using before. The ASICs are quieter, and they are much easier to fit.

As titled

Works great. Make sure you get the adapter cords for the L9. I thought they came with them. They don’t. My L7 works great!

This is one of the quickest deliveries I have ever gotten in the home-mining game. 10/10 would reccomend. No notes.
