Its too much?

[Petan]

Hello i am gonna build this pc setup: 

Ryzen 5 2600

MSI GeForce GTX 1070 Ti ARMOR 8G, 8GB GDDR5

MSI B450 TOMAHAWK - AMD B450

HyperX Fury White 16GB (2x8GB) DDR4 3200

Fractal Design Meshify C white

Its going to be no RGB setup and for cooling and aesthetic i choose one Arctic Freezer 33 TR and 3x Arctic BioniX F120, eSport fan I want put 2 on top of the case and one in the rear. And the Basic two 120 vents put in front. Is it good idea or is only expensive fun?

More than one or two fans in case that is big enough is just expensive fun imo. If you want aesthetic PC, then forget about that fancy glass idea and buy PC case that has real good expansion ability and looks aesthetic. Like be quiet! Dark Base 900 (without glass). Looks amazing, works amazing, lot of place for drives and everything. Or cheaper Pure Base 600.

 

I'm really waiting when people starts to put fountains at the top of pc cases. And some lego rollercoasters route inside controlled by CPU temp.

I mean it's maybe not super nessisary to have that many fans but nothing wrong with that setup. I would say go for it if that's what you want.

Honestly after 4 is when I would say it's doesn't do anything.

It's air, not some kind of fluid that needs to be push out or in. One fan is enough to speed up air convection enough for cooling. If someone don't know what I'm talking about - here is how it works: https://www.youtube.com/watch?v=vw-zuREPFy8

But its true that more vents can provide less noice than only one vent?

I know how cooling works. But you also want to exhaust the hot air out. The difference in temps between 1 fan and 2 is quite significant and 2 to 3 is a good bump as well. I would do 4 because I prefer a balanced approach and don't like positive or negative pressure but that's a personal preference.

Not really, not always. I have Antec P280 case (pretty big) with default 3 fans. I disconnect 2 of them, leave only one at back and with big BeQuiet CPU cooler and good cooling GPU (and semi-passive PSU) it works great with really great tempreatures. CPU (OC i7-8700K) always below 70c, gpu always below 70c and my PSU rarely even start it's fan. And everything is SILENT as hell (except 4 HDDs).

Ok if I chose only one top vent, are these ok, is price well or they are overpriced?

You must choose by yourself - do you want fancy case with empty space inside? This is not aesthetic case, it's "lights & fireworks" case for people who prefer colorfull fans over functionality. I give you an example of aesthetic cases.

[Petan]

And I got another question, is problem to have regular vents in front and regulated on top or in the rear? 

[homeap5]

No problem, it's a choice.

Fans are always better for temperature, worse for noise. You must always choose - better cooling or more silent solution.

Your choice.

I chose whole setup because of functionality. There is no RGB no lights no fireworks, no fancy watercooling etc. But I wanted use some nice looking good vents and I didnt know how many and where. I dont think that this is crazy lighting build or is there something that you would change except these vents?

[Petan]

But thanks you gave me answers that i needed

Not nessisarly. Sometimes having more fans running at lower rpms makes it quite.

Not as much as having less fans running at lower rpms.

Yes but if you need the lower amount if fans to run at higher rpms to cool parts efficiently then it would be louder. It's why 3 fan gpus are often quieter than 2 fan designed.

It depends on the system. Fans are beneficial when cooling is inadequate and adding more doesn't help much after that point. The number of fans also don't make as much difference as fan placement and direction.

Any substance that flows is considered a fluid which includes air. Convection is negligible in a system with active airflow from case fans. 

 

@Petan The top fans might not help much if at all. Front intake to rear exhaust should be plenty of cooling already. If you're going to add a top exhaust, only use the furthest back slot since it's less likely to remove cool air before it gets to any components.

I will  So I am gonna use 2 basic ones, cpu cooler and 2x Arctic Freezer 33 TR and as Brooksie359 said keep balanced approach

There's no point in striving for balanced airflow. Positive airflow helps reduce dust accumulation but there aren't other benefits or downsides to going with positive, negative, or balanced pressure. Maintaining positive airflow is also just a matter or running your intakes at higher rpm than your exhausts as opposed to using the same number of fans. Since intakes are also often filtered as is the case with the Meshify C, using the same intakes and exhausts will often result in negative pressure airflow.

Ok I didnt know that...so what do you suggest?

Moving the stock case fans to the front as intake and using the BioniX F120 as a rear exhaust should be plenty of cooling already. The top fan mounts can be left empty.

Honestly I am talking about a rule of thumb sorta thing. Obviously you can get super specific and try and figure out the perfect fan layout for a build but in general the first 3 fans provide good reductions in temps while the 4th get a small one but I would still say it's worth it. After 4 it's not gonna do much if at all. I also made an assumption of where the fans would go so I wasn't really thinking about direction or placement. Also a top fan is actually pretty useful as alot of cpu coolers place the fans blowing up in which case having the top fan to suck all that air out is quite useful. I am not familiar with the cooler they are using so I am unsure if this would be the case.
