The 8in guard won't fit cuddly an 8in ac infinity silencer. I had to use hvac tape to glue it to the silencer. You need to create these with at least 3/16 extra diameter to truly fit 8in openings cuddly. Also your bitcoin B reduces the amount of air in. I ended up using a tennis raquet like mesh to allow more air in. I would remove that altogether and just add stickers on your shipment
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!!

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

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