mATX case with side and top exhaust fans

Hello there,

I have a CiT S012B Slim Micro ATX/ITX Case wity 300W Power Supply Unit with Built In Card Reader.

It has vents on the sides (one on right for PSU and one on left for CPU fan) and top rear for exhausting hot air that rises.

I'm going to fit an intake on the bottom and wondered whether there was any type of fan I could fit to the rear as another intake?

Great, thanks. Is it worth putting mesh over all the holes in the case or just the intake?

Great, thought that was the case (no pun intended!)

Thanks by the way!

I need a fan that is 2cm or less thick but 60-80mm wide. I'm really struggling to find them.

DJai · 1 Jun 2020 at 19:57

That's right, no more than 80mm total.

Bottom of case, it needs to sit under the bottom PCIe slot (there won't be a card blocking airflow).

I definitely could attach fans to the side vent, not sure of thickness. The issue isn't CPU cooler shoots hot air towards the side vent and adding a fan there would create a hot air trap.

The case isn't big enough for a rear facing CPU heatsink and fan.

Id definitely think about side fans, hot air will find its way out the top regardless so anything bringing cool air in is a plus(just not from the top, then all its doing is recirculating).

Fair point

It turns out I have hoarded over 10 large case fans over the years and some have barely been used.

This is the size of the vent on the side of the case.

Which fan shall I go with?

Two fit quite well, shame these are two pin.

These two were manufactured 2007.

The vented area is 19 X 11cm if that helps.

I've taken a photo from an angle so you can see what I am working with.

The holes on the underside bare for an SSD towards the rear. The ones at the front can only be for breathing space as a fan fitted there would hit the mounting area.

I was considering moving the SSD to the bottom mount and removing the mounting area completed as have no optical drive and planning to use that space for an old PCI audio interface.

Good question, the case has a stand so holes on the base are on the base rather than side.

I haven't tested existing temperatures as I'm still waiting for the CPU.

DJai · 3 Jun 2020 at 13:01

CPU came today, running temperature with side off is 66 degrees.

DJai · 3 Jun 2020 at 14:33

Not even beyond viewing EUFI. Does it make a difference that I've only just fitted the CPU and cooler? Does it take time for thermal paste to bed in?

DJai · 3 Jun 2020 at 16:04

I put the case on and it went to 69 degrees in EUFI.

DJai · 3 Jun 2020 at 16:23

The case cost more than that and I specifically chose it for its dimensions and features.

It's not the case that's the problem given it was basically running in open air with first temperature given.

DJai · 3 Jun 2020 at 18:29

If I take the components out or the case, I imagine getting very similar temperatures.
I
need a case the can stand on the floor and is much smaller than a tower. I spent a long time doing research.

What I am sayingIsaying isdis that I still don't think the case is the problem.

DJai · 3 Jun 2020 at 18:53

I've removed it from the case.

It won't stay on using a Corsair 400w PSU. I've removed the RAM but should still be able to get into EUFI. Nope, it keeps turning off even when I press delete. PSU working fine on another Motherboard.

I've got it sat on the padding it came on in the box and anti-static.

Thermal paste looked like a good even spread
