  • POWERFUL, especially for the low wattage. Love it. Won't buy cosmetically-marked-up fans again.
Size: 8 Inch Color: Silver
I don't care about plastic housings and I'm happy to wire my own switches where relevant, so for me and the applications for which I use fans (in this case, cooling inside my truck/paired with optional swamp cooler water flow), this is awesome bang for my buck. It's a bit loud but I don't care, that's to be expected when going for something with high airflow. I do wish I'd considered getting a couple of different sizes because this is actually more powerful than I need for its current use, but that's fine, sooner or later I'll move it and the attached swamp cooler setup I built to a different larger space and build a new smaller one for my truck. I'd much rather overengineer something than have it be insufficient (like my first pitiful swamp cooler attempt with computer case fans -- fun starter project to learn about wiring in series and wiring a three-prong switch, but totally inadequate for cooling the inside of a Ford Explorer!). So yeah, can't speak to how good this is for actual use in ducts, but as a cheap powerful basic fan for a DIYer doing something fan-related, it's a great buy and I'm thrilled I got it. The only way it could be more perfect would be if it had an on/off switch already integrated into the power cord, but that's not a big deal and of course it's not like it advertised/implied that it would have one. It's exactly what I expected, except more powerful. Everything about it seems solidly made and I anticipate it'll last a very long time. I'll most likely buy from this same manufacturer again in the future when I need fans of other sizes. ... show more

  • Overall quite surprised
Size: 6 Inch Color: Silver
I was surprised at the quality and the effectiveness that this small basic fan offers. I thought I was going to have to buy a high priced fancy one but this does the job perfectly!!

  • Booster fan for computer & room cooling
Size: 4 Inch Color: Silver
The media could not be loaded. At only 100 CFM, this fan isn't too bad. If 100 CFM is what you need. I was expecting more from the design, I guess. With adding an 8 gig video card to my recent computer build, the temps on my chip cooler sky rocket to around 104°F or 40°C on many games, from an average of around 82.4°F (28°C). Which isn't too bad really, but I want to add some filters for dust, & having 104°F pumping into the back room, makes it very hot on a summer day. So I searched around & found this, that I thought would be a solution. I figured it was better than a large Molex powered fan. What I wanted, was to remove the heat that the computer was pouring into the room, with a powerful fan & vent system. All of the air flow goes in the direction of the top vent, & out already. Now I want to pull it out of the room, to the window to the outside. The video card is loud enough on it's own (see review elsewhere), so adding filters to soften the sound, as well as a vent to pull the sound, should reduce it, along with the heat. I looked over Amazon & the net, & found this had the most "quiet sound". Quiet, being relative to the user, of course. Some reviews said it was loud (it is). As you can hear in the video, it is louder than the filtered & non filtered computer. Just to give you an idea. The computer has a twin active fan on the video card, A T-1 thermal tower for the CPU, a 120" side panel fan, & some case fans; on it's own it can be a little loud. Mostly it's the video card, as a simular tower build w/o the 8 gig video card can't be heard (see Black Ice Monster review). So, noise isn't winning any awards. The video is via my phone, not great, not bad. Gaming headset doesn't pick it up, as an FYI. The second & most important thing this Vivosun booster fan needs to do, is evacuate the heat from the computer, so that it doesn't enter the room. The third thing it needs to do (on this checklist), is keep the computer cool. Preferably below current temps, but with in an acceptable range, as long as it's evacuating the room. So far, it's doing #2 alright. Bottom line: With the computer filtered & shut; it will drop the temp about 1-2°C in about 2 minutes. With the side panel off, it will drop it 5°C in 1 minute. The mean running temp in spring: is 35°C (95°F) Under load 43°C (109°F) With the fan off the computer has reached 52°C (125°F) under load on a simple game (Little Nightmares), & the VivoSun brought it down to about 42°C in about 10 minutes. Outside it was around 82°F, the room about 75°F with a pole fan running. So it does alright, just not great. It runs helps at about 5°C on average, but it does evacuate the heat to the outdoors for the most part. I can't say if the 240 CFM fan will do any better as I'm afraid it will be much louder. It's not horrible, just not quiet It sounds like an A/C unit. Oh yeah, it has a tick now after intermittent use in three months. I don't run the vivo fan when just doing text or surfing, only when gaming or doing 3D stuff. Also, the power cord is plenty long great job !! I have it on a wireless remote so I just click & on. ... show more

  • Keeps duct clean of lint vs. no booster fan
Size: 4 Inch Color: Silver
Easy install Wish cord was longer Had to install an outlet since it's in the ceiling between floor joists. Could have used an extension cord (just not as aesthetically appealing). Works perfect

  • 71db, not 37db, which is LOUD. Vibrates a ton, has loose wiring, is a piece of crap. Avoid.
Size: 6 Inch Color: Silver
Cons: 71dba measured by a dedicated SPL meter at 18" distance in open air at 120v, not the advertised 37dba. Vibrates a ton. The ~3" of excess wiring to the hub is just dangling loose in the airflow path without wire management or strain relief. Lowering the voltage as low as I could get it to spin and the lowest noise level I could reach was 45dba, but at that point, it's spinning so slowly it's useless as a fan. For a "quiet" fan, it's worthless. Housing is far from round, but it seems to push roughly the advertised 240cfm at 120v. ... show more
