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 Antminer 4in1 — coverage for all four 4 Pin PWM fan headers on S19 Antminer control boards. Most Antminers pre fall 2023 (Pro, J Pro, T, A-Pro, J Pro+) will require this spoofer
2️⃣ S19K Pro Pack — this includes 4x spoofers along with 2x extension cables to work with the news fans on the K Pro
3️⃣ S21/S21 pro Pack — includes new version of this spoofer with 4x extension cables to the single spoofer board. Perfect for these new control boards!
4️⃣ IceRiver 2 Pieces — these pesky manufacturers have their fan pins in weird spots, so you will need 4x adapter cables as shown in the picture to connect to their respective control boards
5️⃣ Antminer 4in1 for KS3 — tested and working with the Antminer KS3, the standard 4in1 spoofers (1️⃣ ) won't work after a recent firmware update from Bitmain.
5️⃣ Antminer KS5/ Pro — tested and working with the Antminer KS5 series, the standard 4in1 spoofers (1️⃣ ) won't work after a recent firmware update from Bitmain.
Hardware includes 60 day warranty from date of shipment

Let customers speak for us
Removed stock fans and installed the fan shrouds on a S19 K Pro along with a Njord board to control an AC Infinity 8" fan. Much better cooling along with much lower noise. The fan shrouds are thick, heavy duty, and fit perfect. Highly recommended.
Love the look and functionality of my new S19 shroud kit. Much quieter and make mounting on my garage wall look real nice. I went into a 8" 90 deg pipe to a vent outside my wall so I can run it all year without overheating my garage.
Good quality printed enclosure for home mining! Would buy again!
Order was correct 👍
I have placed a couple orders with the guys at Nakamoto mining. A high quality product. Definitely get the Njord board for the most effective energy management on the miner. Bottom line, you are not running thee in your house without some noise reduction. You should buy this RIGHT after getting the particular model of s21. PRO and XP you should run 10" shrouds for max effectiveness. I am testing further. Below pro an 8" will be fine. The 10" shroud increases your form fctor by 12" in length and is considerably "bulkier" than the 8" fan and shroud. 10" shroud kit on an s21 XP is 41" long. You need 110 power by your 240 as well. Also an 21 needs a 30AMP pdu and you cn only run ONE per 30AM pdu. my s21s have drawn as much as 22 and onthe shroud run 11-14 amps. Further testing needed. Great product. Thanks Nakamoto San!!
Print quality on the KS5L shroud was solid. The Kaspa fan cover got a micro crack when I put it on, but works fine and isn’t noticeable. The plebtech board is like magic. The stickers and extras made my day. All around good experience. Shipping could be faster, but wasn’t bad.
These are hands down the most beautiful shrouds on the market. barely looks 3D printed. Highly recommend these
Super quick, quality delivery and working very well. Just as advertised!
Fantastic product.
These work great. I've purchased almost a dozen units and not one has failed. Worth every penny. Make sure you use AC Infinity fans and the Njord board fan controller as well. Super easy and quick way to domesticate your ASIC.
Fits perfectly with the ac infinity!
Shrouds look and fit great. I will order more. My garage will be toasty warm this winter.
I'm in France, the shippment was very fast and the product make the job, I have test one only and it work...
Perfect
Fast shipping and works with ks5 and ks5-pro
Works great with my S19J Pro hashboard and APw7. Highly recommend
