[SOLVED] Fans setup suggestions?

[AntoniettaRiviera86]

My case configuration is like this: a 240mm AIO in the front, a normal 120mm fan also in the front, two 120mm fans in the top and one in the back. Which fans should I use as an intake and which ones as an exhaust?
Thanks

Make and model of your chassis? You should also include the make and model of the fans you're working with as well as the specs to your build.

List them like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:

Ideally it should be intake=exhaust but that's taking into account that all the fans are the same(CFM and static pressure wise).

It's OK, you aren't the only person who is a kind of beginner, it's the biggest reason most of us are here, to help.

The general concensus is that heat rises naturally. So with that as a basis, intake fans are set low and in front, and exhaust fans are set high and in back. This will create a wind-tunnel affect, called airflow, of air going in one end and out the other, hopefully picking up heat along the way.

Which would mean the rear and top fans would be exhaust, and the 3x fans in front are the intakes. A fan has 2 sides to it. A pretty side, where all you see is just the fan blades and sometimes the led/rgb rings, and an ugly side where you'll see the wires, the fan motor, the struts holding the fan assembly and the sticker with all the fan motor information. Because of blade design and direction of spin, air goes in the pretty side and out the ugly side. This is important to determine airflow direction as much as fan placement, especially when adding a radiator.

With radiators, fans can be mounted as 'push' or 'pull'. If a fan is mounted pretty side visible, it'll 'push' air through the radiator, if the fan is mounted ugly side visible, that'll pull air through the radiator.

With your setup, for aesthetic purposes and having 3 fans visible in front, you'll want 'push', the radiator mounted inside, all 3 fans mounted pretty side outwards in the front of the case. The remaining 3 fans are inside the case with pretty side facing inwards.

If the front fans are not visible, you could use the Corsair's as exhaust and stock fans as intakes. Which fan you place where doesn't really matter as much as how it's placed

Thanks a lot man. I really appreciate your very clear and polite explanation, and now I properly understand how fans work. Really really thank you.

You are most welcome.

I hope you can help me aswell. I decided to buy 4 Corsair ML120 PROs. But on startup they sound like a vacuum cleaner. Is there anything i can do about it? And is it normal? Btw im using a Fan Hub from phantek.

It's not really nice to jump on someone else's thread, but I'll answer anyways.

Yes.
If you are talking about when you first boot up, and are still in bios/post, then yes absolutely they'll be at full speed. The hub has a central control, that comes from software or header etc. This is usually a full voltage/speed situation until cmos sets the fan speeds as directed by the fan settings in bios. If the header is set wide open in bios, no real temp control, then it'll stay that way until windows loads and any fan software or windows settings change the rpm.

This applies to cpu and/or case fans, however it is set up. You can tinker with these settings if you choose to, it's a matter of enable/disable fan control, setting min/max working duty cycle etc but on the plus side, you know absolutely they are working on boot.
