Hiree Quiet Cooling AC Fan Dual 4 inch Ventilation Axial Muffin Fan with 4 AC Power Outlet for Home Theater Receiver DVR Amps AV Computer Cabinet Closet Electronic Equipment DIY Vent Exhaust (Black)

I heat my home with a woodstove that is connected to duct work. The woodstove is located in the basement and the small room that it is located in gets very hot. We wanted some way to draw that heat up into the living room above. I found this and got very excited. It is about the same size as a floor register. I was able to cut a hole in the floor and mount this in it. The cord is hanging in the basement and plugged in down there. The only thing viable upstairs is the top of the fan and the power switch. Perfect! I started it up and immediately heat was flowing upstairs! I keep it on low setting and it is very quiet. The fans really move the air! I could not be happier for the price. I gave it 4 stars because I ordered one and it came broken. Several fan blades were broken off. I liked the design so much I took a chance and ordered a second one. It arrived in perfect condition and I have had no issues with it.

It works well. I have this on my stereo receiver. I have it double sided taped to the receiver. I didn't want to drill and screw it. The only thing erking me is the fan speed / off switch is on the other side of the power outlets. So it you tape or screw this thing down you have no way of changing fan speed or turning it off via the switch. You can mount it upside down which would not be a easy thing to do and then you would not be able to use the outlets.

I have a 3D printer setup that needs ventilation, and this works great. Popped it into my window and added exhaust hoses to each fan blowing out. The plugs work as expected, and it is pretty quiet. Great purchase.

I installed this in my aquarium cabinet, great for air flow to keep the sump cool. The additional outlet are a super feature, worked out for all the equipment needed, pump, heater, light, skimmer. Can't go wrong with this fan... Great Buy☆☆☆☆☆

For the price i thought it would be lacking in quality. Ir seems well made. With what seems like good computer fans with good air flow. I will purchase two more for my tent

works great

Price was sweet. The power outlet works superb but the fans were loud out of the box. You can hear a buzzing noise coming from the motor. I think the bearings are not balanced. I will probably replace the fans with Noctua.
