In making this next generation gaming computer, with an 8 gig Radeon video card among other things, the blowing or ambient heat from the computer is enough to heat a small room. I can & have used it in the winter to do that. Well, I was running something, & it was on over night. In the summer, I want to expel this heat so I can stand to be in there, gaming. Trying to get the right CFM to noise ratio can be difficult in a computer environment, in a small room. Mainly home based. This extractor from VivoSun is a great one. It's not quiet, & sometimes I can't wait to turn it off, but it pulls out the heat like I want it to, well, enough to keep the temps nice. Generally, the CPU's radiator will get up to about 107°F-113°F (42-45°C ) with this 195 CFM fan bringing it to (32°C-37°C) 89.6°F-98.6°F & it's pulling most of that heat out the window. I included a snap of some general video editing temps with out the VivoSun, & the bottom one is after it got going. The temps dropped in about a minute, which is super fast! When I "forget" to turn it on, & the computer gets up to about 45°C, it takes the exhaust about eight odd minutes to bring it down to 35°C & about a full 10 minutes to level off at 33°F. So that's not bad really. I have tried a small CFM unit (106 CFM), but the pull just wasn't there. I have included a video so you can hear how it sounds. Of course, it's muffled a bit, being I captured it from my phone, & recordings always sound different than your ear. If I can, I'll try to include a video of the room's cooling turbo fan so you can hear them both. Not bad, but not whisper quiet. They don't claim to be, either, so nothing on them. If I bring the tower down to the floor, or move it away, that will change things a whole bunch. If you're thinking about adding an external cooler to your gaming/video unit, I strongly suggest VivoSun. The product works great, & they are on top of any blips you may have. In fact, they helped me upgrade to this unit with a matter of an e-mail. That's AWESOMENESS to the 10th! Now I don't have to "worry" about leaving the computer on for a bit while I'm in the middle of a game, or when I step away for a moment. I know that this exhaust fan is going to keep the system cool. Bottom line, this exhaust fan works very well sealed to my tower's top fan port. So much that I will be adding a smaller one to my 3D printer to better help regulate the temps in that case. I did need to purchase dryer duct (hose), & a 4" inlet pipe. The aluminum tape & clamps came with the dryer ducting. I used some sticky sound dampening on the I/O exit panel to better direct the air flow being pulled up & out. Also, it has holes in the "feet" for more secure mounting. I just hot glued it.

This blower was easy to connect up to 4” vent hose. Plenty of air and fairly quiet.

Very nice little fan. Very quiet and moves air as advertised. Only reason I didn’t give 5 stars overall is because when I got fan the blades were hitting the casing causing it to make a terrible noise so I took it apart to investigate. You twist the casing and they separate them the blade and inner workings are exposed. Everything was tight like it should have been so I noticed that the casing tightened down a little too much when fully twisted together, then I backed it off very slightly and fixed the problem completely. Shroud was still locked in place as it should have been but I put a piece of duct tape on it to hold it from tightening itself up during use. Very simple fix and have been very pleased with its performance every since. I have 2 of these fans and will buy 2 more very soon. I own several different products from this company and have always had good results with them. Update 7/23/21. Recently purchased 3 more of these fans. Can’t beat them for the money. They work very well and are super quiet.

I ended up ordering this 4" inline fan for my exhaust in my 2x2 grow tent cause I didn't need as much power as I needed for my 2x4 tent so I got the same size fan just a step down in the power. I am very satisfied with this product. When hooked up to my exhaust system on my 2x2 tent I have it pulling air from the tent through my carbon filter and out a top duct and the flow of air is perfect for this tent. I get nice negative pressure in my tent and it definitely has enough power to safely clear the air inside the tent. The noise level is super quiet even on Max speed. I have my setup tucked behind my dresser in the corner of my room and you don't even know it's there, and can barely hear the fan running, well unless u get right next to it then u hear slight humming but if your a few feet away you don't hear it. So glad i bought this fan, and the build quality is really good as well. It's built solid, and have been running it 24/7 for the past year and it still sounds and functions like it did on day 1 of use. I would highly recommend this fan to anyone who is looking to get an exhaust inline fan for their 2x2 grow tent.

This thing works great. It did slow down in hot environments, like a half open garage attic in the summer. The possibilities are endless for this unit. Get 4 at a time, will come in good packaging for storage.

I've bought three of these over time and installed them in the same service. I have it installed outdoors in a do-it-yourself radon abatement system. They're cheap, and initially they're very quiet, but after a year or so of continuous running they start to make noise which becomes more and more objectionable. It's kind of obvious the bearings just aren't up to the job. Fine for short-term use, but I've finally learned my lesson.

This fan works well with good air flow. I use it as a 3D printer exhaust fan and it is able to keep the print chamber cool.

56 dB and 98 cfm, so it's 6 times louder and half as strong as advertised. I purchased it based on the sheer number of good reviews, hoping that 14k Amazon customers could not be wrong.
