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

Njord Board — ASIC Spoofer with Automated Fan Control

Awesome shrouds :) Highly recommend

Loki delivers. Single board operation for the summer or power limited locations. Thanks Nakamoto Mining!

An excellent tool to reduce noise & increase cooling for a low cost per cooling unit. I have 3 miners all have the njord bords on them.

The shroud is solid! I hung my miner vertically along with an Affinity S8 inline fan and the thing is SOOO MUCH quieter. Its preliminary setup as I wait for other part to tidy it up.
I love the color I chose (orange!). Thanks for the Fan spoofers as well as the stickers!. Fantastic quality products! If you ever make a Elphapex DG1+ shroud I'll be ordering 2 before you're finished 3D printing the first batch! XD
