Modding case so there's space for fans.

post #1 of 6
Thread Starter 
Hi. My case is too hot, so I've decided to try and jam it with fans, and now I've ordered 3x80mm fans and 1x120mm fan (I know that bigger is better, but I can only fit one 120mm).

I'll show you how I imagine them being placed:
359

now two of the 80mm will fit with no problems, there are already holes for them, so My problem is the 120mm and one 80mm (the one in the bottom a the back)

My english terminologi for this is not so good, but I'll try to explain what I think needs to happen.
Now the one in the back bottom I have these metal plates that I can push down to make space. That doesn't give me a hole however, So I'm thinking that I need to maybe cut in them and drill a hole or something?? Maybe someone has a guide to this?

700

The same applies to the front, although I've bent the slots off, so without the front panel there would be a direct hole into the pc, but as you can see I have these slots (dn0 what they're called) that can be pushed out to make way for drives. I'm thinking I need to do something to them too.
700

some of you may tell me to simply get a new case, and I acknowledge that it is probably a better solution, but I want to get my hands dirty and not just buy my way out of the problem. This is me taking my first babysteps at making something for myself and testing and actually see how it works so I can develop a hands-on feeling of how airflow and PCs can be engineered. It's important for me to call it my own, so please respect that and thank you very much. Any guides, pointers, help or simply your paying attention to this thread is much appreciated.

Ok if you want to add fans to this case what I would do personally would be:
  • Measure to see if a 120mm fan would fit in the top back slot.
  • Dremel out the mesh from the back of the case. (that stuff looks really air restrictive for mesh)
  • Drill holes for the 120mm fan or use the 80mm fan holes if 120mm wont fit.

as for the front of the case, you will need to mod the front bezel and the optical bay covers (the push out slots for drives) to let the fans receive airflow. This may be problematic as the optical bay covers look really tight in there.

What I would do is try and fit a 120mm fan in the bottom front of the case dremel out the metal but leaving 4 tabs in the corners to bolt in the fan. Then cut a hole in the front bezel at the bottom where you cant see it to allow airflow for that fan.

This will add a major amount of airflow if done right and not that much noise, because in my personal opinion for the amount of air an 80mm fan pushes the noise level is just ridiculous.

However this is just my opinion and there are far more knowledgeable people here that may say different but I'm just stating it how I see it.

Thank you. That sounds like some really useful tips. I probably will need to acquire a dremel tool, and I was wondering too if I needed to cut out the back mesh, so thank you for clearing that up for me. There isn't space for the 120mm anywhere else than in the drive bay, but I found some other threads that described the use of foam to place the 120mm fan in the 3 drive bay slots. Then I just need some mesh covers, which I'm wondering how I could make up. I read that some pedo inhere had just used pantyhose, and that sounds like a very nice budget solution for me.

The only fan I still consider to be a problem is the one in the bottom back. I'm not quite sure what I'm going to do there, as I need to invent some holes to fit it in...

I'll just post another picture so you can see the problem I'm adressing:

IMO you just wasted $ on almost useless fans when that $ can be applied to getting a new case... if you keep using 80mm fans, then your case will work itself back up to the original decibel level that you were trying to get away from in your original post... there is a reason why the computer industry has moved away from 80mm fans. they don't push enough air for the amount of decibel they put out...
you could have saved the $ you spent on those fans, and you'd be half way to a new case with native 120mm fan mounts and a MUCH better cooling solution...

According to description the 80mm fans are 17.5 db each, which is less than my cpu cooler, so I'm not too worried. I spent 10$ on all the fans, so I'm sceptic too, but I need to see how this turns out. If not for the performance then for the process of it.

Thanks for the input. Always appreciate opinions invested in my issues.

Yeah I think personnally I would have changed case but if you want to do it just for fun too , what is in the door, with an old case like that its probably a big blank metal sheet and even if its a window its easy to dremel out space for 1 or as much as 4 or 6 120mm fans , just make sure the wires are long enough to open the panel
