How To Update Your Keezer – Adding A New Fan

If you’re heavily into storing your beers (and who isn’t?), then you may know all about kegerators and keezers.

A kegerator is a refrigerator that’s been adapted to hold a keg, allowing users to dispense beer from the constantly-cooled keg.

On the other hand, a keezer is similar, but working from a freezer instead of a refrigerator.

Using a conversion kit, beer enthusiasts can convert an old freezer into a keezer, perfect for ensuring that your dispensed beer is cold enough at exactly the correct temperature range.

However, you’ll want to make sure that your keezer is always cool enough.

One of the best ways to do this is by adding a small fan, perhaps even an inexpensive CPU fan that’s originally designed for computers.

But how can you add a new fan to your keezer?

I’ve got the answers for you!

In my handy guide below, I’m going to explain how you can add a new fan to your keezer, ensuring that it keeps cool at the proper temperatures – giving you perfectly chilled beer.

On top of that, I’ll also explain why keezers will often need fans in the first place, and recommend a fan for you to use. Read on!

Why Do I Need A Fan For My Keezer?

You might be wondering if your keezer needs a fan – and why.

Keezers will need fans in order to make sure that they are keeping properly chilled all over, maintaining the correct temperature range and keeping your beer at the right level of chill.

Whether you’re using a kegerator or a keezer, your goal is going to be the same: you want to regularly dispense cool beer whenever you want it.

The Room The Keezer Is In

However, it isn’t going to always be the case that your keezer is going to keep the beer properly chilled.

This will be the case if your keezer is located in an area of your house that is unheated, or placed somewhere like the garage.

These areas will be unpredictable when it comes to their heat, and you need consistency when it comes to running your keezer properly and efficiently.

This won’t be the case for everyone, because some people might have put their keezer in a room that is climate-controlled.

With a climate-controlled room, you’re able to manage the humidity in the room through various factors – such as ventilation, dehumidifiers, and insulation.

With the humidity under your control, you can make sure that the keezer is operating in an environment that has the correct temperature for it to chill beer properly.


Another essential factor is circulation. Keezers need circulation in order for all parts of it to be kept cool, and your beer to be kept at the correct temperature range all the time.

If you put a hand in your keezer, you might notice that the bottom area is colder than the top area. This means that there isn’t proper circulation going on.

This is understandable, because most keezers will have been homemade from an old freezer with the use of a conversion kit.

When it’s done like this, the keezer isn’t going to be properly circulated, affecting your beer.

This is where adding a fan comes in handy, because it will help the freezer maintain the proper temperature.

How To Add A Fan To Your Keezer

When it comes to adding a fan to your keezer, it thankfully isn’t too difficult. On top of that, there are two ways that you can do it.


The first is a more general, impermanent way. If you’re buying an inexpensive and small CPU fan, which many people do use for their keezers, then it will come with some screws and adhesive.

These will allow you to attach it inside the keezer with ease, and the fact that the fan is small will help because it will be unobtrusive and easier to fit inside.

When it comes to placing it inside, you can choose where you put it. If you mount it at the top of the inside of the keezer, it can push the air downward, and circulate it around.

Alternatively, many mount the fan at the bottom. Since the bottom of the inside of the keezer is colder than the top, the fan will take cool air from the bottom and blow it upwards.


A more permanent way to attach the fan into your keezer is by drilling a hole and feeding a cord through. You should mount this fan at the top or the side, and drill the hole there.

There should be a grommet with the fan which then allows you to run a power cord in and out of the keezer.

This will give it a near-endless supply of electricity, while other fans will just run on batteries that need to be replaced every now and then – affecting the keezer’s performance.

Recommended Fans

There are plenty of fans that you can get to use in your keezer, and many of them are quite cheap.

The AC Infinity AXIAL 1125 is a great pick, available here from Amazon.

AC Infinity AXIAL 1225, Quiet Muffin Fan, 120V AC 120mm x 25mm Low Speed, UL-Certified for DIY Cooling Ventilation Exhaust Projects

Part of the reason that it’s such a reliable choice is that it’s specially designed for DIY projects based around cooling or ventilating products.

On top of that, it’s very quiet, meaning that you won’t be disturbed by your keezer suddenly becoming noisy.

It’s also made of heavy-duty material, making it suitable for various environments, and dual-ball bearings allow either flat or upright mounting – keeping it versatile.

Better yet, it plugs right into a wall outlet, rather than needing to be hooked up to a PC.

Final Thoughts

Adding a fan to a keezer is easy and inexpensive, but will make so much difference to your beer.
