Placed order and paid on 30 Oct 2025, received order confirmation email. No updates or dispatch notice so I email for an update on 12 Nov 2025, I didnt get any reply other than the automated "Thanks for reaching out" reply. Then on 13 Nov 2025 I receive an automated "Your order is on the way" email with tracking number. Waiting Waiting Waiting, the order does not get delivered until 13 Dec 2025. Almost 2 weeks to process and dispatch the order and then another 4 weeks for delivery, and still no actually reply to my email sent on 12 Nov.
I have ordered from Nakamoto Mining in the past and the service was better, now the service is crap and needless to say I wont be ordering from them again in the future. Can get similar products online delivered alot quicker.
Waiting for delivery, now 20 days since the order took place :-(

I wish the fan would automatically shut off when I turn my miner off but besides that it seems to work great

Ordered multiple times, always extremely satisfied with products and customer service. I can tell they have been busy and see some complaints about response time. I get the frustration, but I have to say, in my experience Nakamoto Mining always makes things right, going above and beyond to make up for any delays.
Thx guys this is my 4th order
I love it
I love these 10" fan guards. They are a perfect fit and thats not surprising after I saw how everything was packaged. "Devils in the details"
This system allows unrestricted airflow though the 8" Duct Fan while keeping all the dust and small flying critters out of my Hashboards. Stupid easy to install! Thanks Guys, for another brilliant product. Oh and LOVE those crazy stickers you include!!!
Placed my order, received a shipping confirmation quickly, spoofers arrived in excellent condition (packaged very well), plug in and play. Smooth Transaction. Thank you Nakamoto Mining!
awesome product

Njord Board — ASIC Spoofer with Automated Fan Control
I love how the shrouds look. So many little details added to it and it fits well my inline fan. My only trouble is the spoofer, they dont work for my L9 with the Feb 2025 firmware.
Packaged great, some extras and excellent products.
Impression 3d propre et installation facile
Very happy with the shrouds
I wish the fan would automatically shut off when I turn my miner off but besides that it seems to work great
