  • Pulls out the large video card heat
The media could not be loaded. 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. ... show more

  • Super!
My plants love the air circulation, easy to install, super quiet, and pretty sturdy too. I think that for small scale farming its GREAT!! I got this because I am tired of chem-trails effects on our plants that we grow for pharmaceuticals & herbal remedies and I have had them a month & I am glad I got these. The only way to get any better would be to by major greenhouse ones for pro’s & I may get those next time but for now these should work for a while! ... show more

  • Decents Airflow for the price.
I like the compact design and airflow. I bought this for my enclosed plant shelving. I needed something to move hot air in top to lower shelves. It does a very good job. Only con is noise level. In basement, garage, etc would not be a problem. But not so good for entertainment rooms, living room, bedroom. It's just too loud for that. ... show more

  • After going thru 3 in 2 years I’m moving on to AC infinity s4
They’re cheap and work well for a few months. But without fail each one I’ve bought fails within 4-5 months depending on usage. The sound of the fan failing is unmistakable now that I’ve gone thru it 3 times. Out of nowhere it just starts rattling loudly like it’s got some to int caught in it hitting the blade or something. You can stabilize it or tap it and it stops but then it starts back up again. Nothing fixes it. And apparently it completely falls apart and fails completely but I’ve never waited that long - I need a quiet fan and I can’t handle the rattling for more than a day so I always quickly rebuy the same cheap fan. This was the last time though. Luckily this happened right around Black Friday/Cyber Weekend so I’m getting a new AC infinity at a discount. I already have 2 other AC infinity fans and they’ve lasted much much longer with no problems. So I’m here to tell you, it’s just better economically to get the higher quality fan in the first place and skip this cheap one. It’s not made for long term use. ... show more

  • Well Priced, Reasonably Quiet For This CFM Rating.
I liked this product so well I bought a second one for additional application.

  • No way to activate
There's no on or off switch and no information where to get the app to access it. The only app that my Google search can find associated with this product line does not offer this product as an option that it controls. There's no way to turn it on and no way to use it. Absolutely useless. Troubleshooting instructions say to refer to the user guide there is no user guide. All I have is a postcard that says plug it in. Did that, nothing happened. Manufacture website does not have any sort of troubleshooting, user manuals, anything other than email addresses and a phone number which is, of course, not manned at the time that I'm trying to install this. ... show more
