I picked up a meshify C and 2 extra fans of the same type it comes with for a total of 4, the question is should I do an equal 2 in, 2 out ratio? or 2 in 1 out? Im aware of the different pressures, too much intake is positive, too much exhaust is negative, but what about equal? I figure it would be fine but I also never see a pre built with 4 fans, its also 3, why? Why 2 in 1 out? Are they just cost saving, or is there a  benefit im missing?

I'd do 2 in at front, 1 out at top, 1 out at back

That was my plan yea, because my current case I noticed my 2060 puts out quite a lot of heat that pools up top with no way to be extracted out.

Positive pressure is the goal with as many intake that you can and one exhaust at higher RPM

Well sadly that won't work for me as all the fans I got are the same size and RPM, unless I got some sort of program to increase the speed. 2 fans is worse than 1 faster fan?

Where are you plugin your fans? on the motherboard i guess...

You can adjust the speed from Bios

Yea ill be plugging all 4 into the same header, hopefully it can even handle that, its a budget motherboard, had to buy a 4 way splitter. If it can't handle it ill be big sad.

I wouldn't plug more than 3 fans on one header...

check the fan specs and the motherboard specs. usually the fan headers output max 1A. i can daisy chain 5 of my arctic fans as they are rated at 0.2A each, but each fan is different, so make sure to check first.

Can it damage my motherboard? I assume if it cant handle it, they just wouldn't run, but if theres a chance of it frying something then im boned, cus I can't afford a mobo upgrade right now.

Do you know where I can find specs of a motherboard other than the direct website? Because gigabyte is big stupid and didn't put the fan header amperage on the website.

motherboard manual?

Yea I found it and its garbage, literally 0 information on the port other than that its there. let me try looking up a better manual or something.

[OnionRings]

What useless information http://prntscr.com/r95j0x it says everything but how many amps it supports... SMH

[OnionRings]

Well I assume http://prntscr.com/r95mzp these 2 things are the most important information on the fan. Amp is slightly less than .2 per, and the voltage to start the fan is 4v, so IF my header is a 1a 12v then I should be able to run 4 fine... or not? I don't know... fuck me why did I buy such a cheap mobo all those years ago lol.

Ive got no reply from gigabytes twitter yet.

Most modern motherboards will support up to 1A so 4 should be fine. What are your specs?

Yes. 

As for pressure, the only benefit to positive pressure is reducing dust accumulation with filtered intakes. It's not that big of a deal.

Depends on the fans used and at what speeds as well as where the fans are placed and how they may be obstructed.

Ok, forgot to update this post. I got my case, came fast as hell, but my extra 2 fans took forever, and ive also been procrastinating my build swap, but now that everything is here and ive got some free time tomorrow, im gonna do the swap.

 

So I asked opinions on the fan arrangement, @boggy77 suggested I do 2 in 2 out, which was my original plan, but @Constantinrecommended 3 in 1 faster out, which I can't do because all 4 fans are 120s at the same speed.

 

@WoodenMarkerSorry for not replying, I missed the notification for your reply. 1. My specs are in my sig. 2. Yea that's not a big deal for me either, cleaning more or less is not a big deal at all, especially since im used to cleaning my current POS pretty frequently. 3. I have 4 120s all the exact same model.

 

With all that being covered, I am going to try to run all 4 on the same header, 2 of you said it should be fine with 1 of you saying you do it yourself, if they don't all power on then ill just have to do 3 fans, but in the event all 4 work, should I do 3/1 or 2/2? I'm guessing 2/2 is better as I do have this 2060 that gets pretty hot, and I don't think a single 120 is going to be good enough to exhaust all that heat.

 

Also a follow up question if I do 2/2 that means 1 goes in the back, 1 goes on top, the top has a magnetic dust filter that spans the 2 slots on the top, if I put 1 exhaust on the top, does that mean I should take the filter off right? To keep air flow open, and to not let dust be trapped inside? What about dust that might float in the air or fall off my roof and fall into the open slot? Do I just deal with it and keep my PC clean?

Keep the top filter on

Ok.

 

To add, I ran a CPU-Z stress test and my CPU stayed at a pretty cool (as it usually does) 54c. However, when I added a furmark 1440p stress test on as well, as expected my CPU climbed to 66c... so I'm going to go with the 2/2 method, to keep that CPU temp down while gaming. GPU stayed at 67c btw, very respectable and honestly lower than I thought it'd be during a 1440p test, but because of the aforementioned CPU temp increase, I think the case swap is still a good idea. More fresh air coming in, more hot air going out.

 

Thanks to all for the help. Will post back tomorrow with my temps in the new case!

[OnionRings]

I got lazy and forgot to post. Definitely an improvement though, hottest CPU temp was 58c and GPU was 63c after 10 mins of furmark and cpu-z at the same time. Probably coulda ran a better cpu test than cpu-z but w.e, so far thats an 8c decrease on cpu temps alone which was my goal.

How much of a problem settling dust is depends on the environment and how often you use the system. With the fan always spinning, settling dust is basically a non issue at least in that area. It's also better for airflow.
