What screws do I need to add another fan to my PC?

[Beilish]

Hello

I have an Antec P100 case which came with 1x 120mm fan at the front and another one at the back. I'd like to add another fan so i bought 2x 120mm Antec Spark 120 fans. I only connected one of them because I don't have another set of these longs screws anymore. The case is with me for about 6 years so there's no way I'll find the parts it came with.

 

Where do I buy new screws? I found some silicone screws on eBay but I'm not sure if it will fit...

Thanks

You should be looking for 5.5mm fan screw.

Hello

Your new fans should have come with screws, or maybe only cases come with screws actually...

And you probably want to put all 3 fans as intake in the back/top of that case since the front has no airflow with the door on.

I only have 2 fans in total. One at the front and one at the back. Nothing on top. I don't agree there's not airflow.

What do you mean? In the front of the case? There's a dust filter and foam built in with almost no gaps for airflow there.

Yeah but it's not like it's sealed. I agree there's not much airflow but 2 fans will still be better than 1.

You can just make the front your exhaust though, because the top has mesh, and if you put both fans up top your CPU/GPU will constantly get fresh air.

So 1 fan at the back, one at the top and one at front or should I just put all three in the back and top? How will the air exit that way?

You'll have positive pressure forcing the air out of the front of the case and the PCI-e slots in the back, Could also flip the PSU around to it's acting as exhaust as well in that config.

 

Should be pretty similar to this antec case

So to sum it up.

Back: 2 fans

Top: 1 fan

Flip PSU

Front: Nothing

Should work the best given that case. having them all be intake.

Not counting just removing the front door, but it should still help with noise too
