## Customer Reviews

### ⭐⭐⭐⭐⭐ Highly effective (don’t use duct tape)
*by S***E on November 1, 2023*

I’m using this for residential crypto mining with an 8 inch S8 fan. It is crazy loud, but still quieter than the fans on the mining ASIC. Before buying this, it was just too loud to run at night, costing me income. The fan needs to be at least on level 8 during the day to cool the hash boards, and that is really loud in a residential area. For grow tents, you probably won’t need to run it at level 8 unless you need a jet intake in your tent for some reason.This is perfect. It is so effective that I can run the fan at 7, maybe 8, even at night. It also doesn’t restrict the air flow much at all, and temperatures are not affected. I have an 8 inch duct filter on the end, and it’s even more quiet.Oh yeah, and don’t use duct tape. It defeats the purpose a little since sound will get through the joints. AC Infinity sells 8 inch silencer clamps which is a tube of thick rubber and a clamp at each end. Not only is this more secure and cuts down on sound, but they make your setup look really clean. Another clamp was needed for my filter, just fyi.Note: if you really want this in silver, you may need to request it. Mine came in black, but still looks great.

### ⭐⭐⭐⭐⭐ Super effective
*by K***N on May 24, 2025*

It really cuts down the noise from the fan, I can run it two settings higher with this. To my ear the tone sounds better too

### ⭐⭐⭐⭐⭐ What's that noise?
*by J***Y on May 20, 2024*

What's that noise is not what you're going to say after installing a silencer on both ends of your inline. Coupled with noise reduction clamps to have you trying to figure out if you're hearing the inline or the clip on AC Infinity Cloudrays. Easy to install, nice snug fit with the AC Infinity noise reduction clamps, heavy duty feel with the performance and luxurious look of AC Infinity products. Recommended for those that want a quiter growing experience.
