My DIY solution to mounting 120mm fan into a 5.25 bay

So I wanted to mount a 120mm fan into my 5.25bay at the top, having a google around it seems quite hard to come by an adapter nowadays. I could have used a 120mm radiator bracket (too expensive) or just some tiewraps (does not work well with my ocd lol).

It's more difficult than it would seem to mount the fan so it can be removed easily with just a screwdriver and from the front/sides only, due to the rad pipes at the back blocking access. Then I had a brainwave, I had an old DVDROM I had just chucked in the bin. Bit of measuring and dremeling later I had my solution which slides in and out and fixes with 4 screws:

DVDROM stripped down and cut in half:

The two halves from the front:
73299

Mounted in the drive bay to test fits ok:

The fan fitted to the brackets ready to slide in:
73301

The finished article:
73304

Probably someone will link to a better solution, but I enjoyed the satisfaction of making this with zero cost 🙂

Even if you decide to change to an off the shelf mount later you haven't lost anything since this only cost a dremmel disc. 🙂

Exactly! There are a surprising lack of off the shelf mounts I found..

Well, there's stuff like this radiator mount but it's $15:

I'd have to do some hunting to find something inexpensive. I think the reason you didn't find many is that most people just use the mountings that are provided by the case. So if there isn't a mount where they want a fan they just put one somewhere else and call it good.
