It took a while to find the right fan for my project. We removed an old oven and added a microwave into a new closed space. I'm working on new building new drawers underneath now. I may add another air vent later, if needed.
Anyway, I was worried it the microwave might overheat so I added this two fan system. There's also a fan underneath the microwave and it draws air in and then the fan in photo draws air out on the outside. I set it up so that the fan turns on at 90 degrees right now. I very happy because I don't have to manually turn the fan on when I gets hot. Also because it looks great and is super quiet. It really works awesome.
I had looked at fans that were specifically made for putting in walls and there was nothing even close to quality, quiet-ness, options and price point. This is basically every a really I am computer USB fan. I really couldn't be happier. In fact if this fan ever broke, all I would have to do is buy another usb computer fan and replace it. Computer fans are really easy to find and they work terrific. That said, I have no reason to buy it from another company I'm just making a point that these are just really high-end computer fans. If they can work in a $3000 computer, they can work for a $300 microwave.
This company makes a really awesome products.
Fyi, I did scratch the white paint on the edge on one of the fans a little when installing it. I was trying to sand some paint on the wall. Had I done it again, I would have uninstalled the fan before sanding or covered it with some painter's tape. It really was my fault. The comfort level exceeded expectations. It fits perfectly in our space.
