desertcart.com: AC Infinity CLOUDLINE PRO T6, Quiet 6” Inline Duct Fan with Temperature Humidity VPD Controller, WiFi Integrated App Control - Ventilation Exhaust Fan for Heating Cooling, Grow Tents, Hydroponics : Patio, Lawn & Garden

Review: AC Infinity CLOUDLINE PRO S6 – Quiet and Powerful Cooling for My Miner Room - I purchased the AC Infinity CLOUDLINE PRO S6, 6” Inline Duct Fan with Speed Controller to help keep my miner room cool, and it has exceeded expectations. The EC motor is both powerful and efficient, and what surprised me most is just how quiet it runs, even at higher speeds. Installation was straightforward, and the included speed controller makes it easy to adjust airflow as needed. Running multiple miners can heat up a room quickly, but this fan has made a huge difference — it keeps temps under control without adding a lot of noise or power draw. The build quality feels premium, and I can tell it’s designed to run continuously without issues. ✅ Pros: Very quiet operation, even at high speeds Strong airflow to keep miner room temperatures down Speed controller included for precise adjustment Efficient EC motor saves power over time Solid build quality, designed for 24/7 use ❌ Cons: Higher upfront cost compared to budget inline fans Speed controller cable could be a little longer 💡 Tips: Use insulated ducting to further reduce noise. Mount the fan with vibration-dampening straps for an even quieter setup. Pair it with a temperature or humidity controller for automatic adjustments. Clean the fan and ducts periodically to maintain peak airflow. Bottom Line: The CLOUDLINE PRO S6 is a top-tier ventilation fan that’s perfect for high-demand environments like mining rooms, hydroponics, or grow tents. It’s quiet, efficient, and powerful — exactly what you need for reliable cooling in a 24/7 setup.
Review: The Rolls-Royce of exhaust fans - This is my third, and likely last, exhaust fan I've bought for a project. I wanted an exhaust system for our cat's litter box cabinet so that it would create a small amount of negative pressure and pull the bad odors outside. This fan is absolutely perfect in every possible way and has far exceeded my expectations. I arrived at this fan, after purchasing two others that were just too loud, as the noise seemed to bother the cat. I installed 2" PVC in the wall behind where the cabinet is, because I needed something small enough to fit. I then had a 90 degree elbow coming out of the wall, through a cover plate and then going into the back of the cabinet. In the attic, I installed a 2" to 4" duct adapter onto the 2" pipe, ran 25' of flex duct to this fan, and then another 16' run of duct to the roof vent. While the first two fans where very noisy, even at the lowest speeds, this one is virtually silent. I'm running it on level 2 and cannot hear anything inside the cabinet or in the house. Since I'm restricting the intake to only 2", anything above level 2 would likely just be a waste of power. This setup is working perfectly and creates more than enough exhaust to do the job and it does it in silence. The prior fans moved the air ok but had a really annoying hum that could be heard through the ductwork and also inside the house through the insulated ceiling. I hear nothing with this one. In addition to the above, the fan is rock solid and came with EVERYTHING one could possibly need to install it, including hose clamps. It's almost overkill but shows attention to detail. It also came with a very nice instruction book (yes, it's a substantial book) with detailed instructions on every aspect of installation and operation. The speed controller is very nice and easy to use. I just set it to my desired level and forget it. It will remember its current setting and resume after a power outage. This fan cost a bit more but is absolutely worth every penny paid. The difference in quality and quietness cannot be matched. I could not be happier, cat is happy, and we have an odor-free home.

## Questions & Answers

**Q: What are the cfm rating on it?**
A: From their site, "Duct Size: 6” | Dimensions: 7.9 x 12.6 x 8.4 in. | Airflow: 351 CFM | Noise: 32 dBA | Bearings: Dual Ball". Just installed one of these; a great little fan and quite quiet esp at low speeds. High speed fan sound is noticeable but it is really the sound of rushing air and not a motor sound.

**Q: Humidity and temperature way off does anybody else have this problem? Can it be fixed**
A: If all of you that have problems with these would read the instructions you can calibrate both temp and humidity as well as fix any problem with your fan not working it’s probably not turned on or is in the wrong setting check the instructions before blaming the unit these things are great in my opinion

**Q: Where is the humidity sensor? Is it on the sensor probe that also does temp?**
A: The probe acts as sensor for both temp & humidity

**Q: When unplugged and plugged back in will it return to the same speed as before? I want to add a switch to the outlet.**
A: I just tried it because of your question, yes it does, but I think you're asking about a timer situation, I would say that you shouldn't bother with a timer, the reason to get this fan over others is the programmability, this thing self adjusts its own speed based on the high/low temp and the high/low humidity that you enter, the power used to run it is very small.

### ⭐⭐⭐⭐⭐ Used it to Boost the Exhaust of a Falcon A1 Laser Engraver
*by M***C on February 1, 2026*

This review is for the 4" version of the AC Infinity CLOUDLINE PRO, also known as the S4. My son had received a Falcon A1 Laser Engraver from his wife for Christmas and I offered to create a custom exhaust setup for it. They have a young child and what I had read about the possible toxicity of laser engraving fumes (specifically for leather cutting and engraving) motivated me to get the fumes completely out of their house and garage. After a few hours of research, I zeroed in on this CLOUDLINE PRO S4 for the task, as well as some 4" flexible duct and a silicone elbow/reducer (4" to 3", also found on Amazon). I was not disappointed with the results! See my two photos. I'm very methodical and careful, so it took me a few hours to complete the system, but most of that time was spent sawing through the garage drywall and configuring the termination of the duct at the roof's soffit. My observations: The inline fan is fairly big, but lightweight and is very easy to secure to the wall with the included mounting bracket. It's very quiet! The ten-speed variable control will take it from too quiet to hear, up to a whisper, and finally to a slight swooshing sound at full speed. I was impressed with the air volume it moved. I could definitely feel the air coming from the outlet outside. It reminded me of the volume of air a clothes dryer would produce. Sure enough, with a rating of 205 cfm (likely measured without ductwork), this fan compares to the average clothes dryer exhaust of 150 - 200 cfm. A bonus for the setup I installed is that garages are very leaky and exhausting this much air will bring a similar amount of outside air as "makeup air" and will create a cooling effect for the garage when it's hotter inside than outside. Everything I read online indicated that AC Infinity made good quality inline fans and I got the same impression working with it. Even the packaging and "presentation" upon opening it was far nicer than I had expected. I would definitely buy this brand of inline fan again the next time I need this type of ventilation.
