Question Airflow suggestion

[Sagi sason]

I have a case with only 2 places for fans, a 80mm on the back and a 120mm on the side.
What air flow should I do?

 

[hambuckles31]

Use the 120mm as intake and the 80mm as exhaust. Also try and get fans that are high air flow.

 

[hambuckles31]

Look for fans that have high CFM at about 70 or above

Can you show a picture of the case?
What components are you trying to cool down?
What temperatures are you getting currently?

I don't exactly know what the temperature but I don't have any fan right now. And I don't know what I want to cool, but I think the cpu and gpu

Show a photo of your case (upload to imgur.com and post link).
List technical specs of your pc.
Check temperatures of your system with MSI Afterburner. Make a screenshot, post that too.

Your case probably has space for front fans too.
Remove side panel and check it.

Yeah I found out it does have another 120mm on the front, so what I should do, inside from the front, outside from the back and what about the side panel one?

 

[SkyNetRising]

If you have frontal 120mm intake fan, then just add rear exhaust fan.
Looks like you could put 80mm or 90mm fan in there.

As for side vent - I'd just close it with some tape to prevent dust buildup inside the case.

So I shouldn't use the side one? Even not for outgoing?

 

[SkyNetRising]

There's no point in using side spot for exhaust, if you set up rear exhaust fan.

But for intake it would need a dust filter.

You mean for the one in the front?

There's a big difference between air and air flow. You could mount a fan on the side panel and get a ton of air dumped into the case, but have next to no actual airflow. You'll see immediate temp differences on things like the gpu and cpu, but it's the far reaching temps that are important. Those being the case temps after an hour of heavy gaming where the case is fully heat saturated, everything from cpu/gpu to drives has steadily increased in temp, because what's going out is less than what's coming in and none of it is orderly. The air doesn't flow, it just goes around in circles, bringing the heat with it.

1 fan in front, 1 fan in back and block off the side panel hole. Gives the case the best chance of actual flow. That'll regulate case temps overall far better than a side fan, which just ends up blowing air in every direction.

Wow, thank you. But I also need to install a dust filter for the front fan?

 

[Karadjgne]

Open the door/pull off the front panel. From the picture it has venting on the side at the front, so the fan will ge in there and there should be a filter although there's no guarantee of that.

Case looks very familiar, just can't remember what it is exactly.

I didn't understand, there is no filter in the case but there are a venting on the sides, it means I don't need a filter?

I found an old PC and took his fans just for now
But they are almost not doing nothing

And also, it's just a very cheap prebuilt PC so I don't think it even have a name

 

[SkyNetRising]

That means, you have an ancient, low quality pc enclosure without any dust filters.

Maybe - it's time to get a new modern pc case.

I don't have a lot of money and I really need a new monitor, but does it means I can't install a dust filter?

You certainly can install fan filters.
Problem is - your case is not built with fan filters in mind. It's not even built with airflow in mind.

There are a lot of openings, that let unfiltered air in. The case supports small size fans (they're loud and not very efficient). You'll have to do a lot of modding to make it function properly. And you'll probably will never be able to make it function as any modern airflow oriented pc case.

I don't have a high end pc, all I need is just to babble a little air flow for cooling. I think it would be enough.
It's just i3 8100 and gtx 1050 ti

 

[Karadjgne]

Is it possible to mount that front fan inside the case? That would solve multiple issues. And an air filter can cost next to nothing, you can build one out of an old pair of panty hose, some glue and a piece of plastic with a hole cut in the center. One of those magnetic signs ppl use on cars etc found in any hardware store would be ideal.

no, its not possible to mount it inside.
