Start by drilling your fan mounting holes.
Tower cooling fan kegerator.
Blast cold air up into your beer tower and eliminate foam and first pour warm beer.
Coldtower kegerator tower coolers are the all around best tower coolers you can buy.
When you want your house or car as cold as possible what do you do.
Others use weak computer box fans not capable of high air flow and not designed to blow directly into an air hose.
Coldtower is the only kegerator tower cooler that uses a blower specifically designed to blow a stream of high velocity air into an enclosed area.
If you are not the diy type you can just buy a tower cooling fan here owners of a kegerator with a draft tower whether your beer dispenser is commercially made or a kit conversion you can add some cooling power by modifying the tower with a cpu cooling fan.
The holes should be 1 8 if you plan to use 1 8 rivets to mount your cooling fan or 3 16 if you plan to use 6x32 screws.
Larger diameter hoses like those used in economy tower coolers restrict the flow of return air into the kegerator resulting in inefficient cooling of the tower.
Buy it now see more information.
Upgraded 1 2 hose is the perfect diameter to supply a steady stream of cold air into the tower and allow ample return air into the kegerator.
You will build a small fan and enclosure using a computer cpu cooling fan enclosed in a small plastic box with a hole cut to allow cold air to be sucked in and pushed out through a hose inserted through another hole in the plastic box.
To summarize the project.
We use fixtures and templates to make sure the holes are in the same place every time but you can use the fan body to mark and drill the holes in your housing.
