Need 2 or 3 (depends) Case Fans

[Orangeator]

Okay, so I have an exhaust fan that honestly I don't believe can keep up with the amount of air my Hyper 212 evo is blowing out. So I have the exhaust fan that came with a cheap case I have that spins at 900rpm at 100% usage... My hyper 212 evo is blowing right at it and I feel more air coming from the 212 then the rear exhaust. So I need a good exhaust fan that is going to suck a ton of air out, and I need a fan that is going to blow a ton of air from the front of my case, because currently I don't feel any air coming from the free case fan that is in the front. These are both 120mm fans. I would prefer not to spend more then $10 a fan however I can splurge a little but if it is worth it and go $25-$30 for both if it would be worth it. I have a 280x so that tends to build a lot of heat up too. I do have a 140mm side fan blowing on it however it doesn't put out any air either. So if you can fit a 140mm side fan within the $30 budget then by all means.

 

Edit: Budget raised to $40.

$10/fan is pretty hard to do...

if you need to stay within budget get this maybe?: https://www.nzxt.com/products/fn-v2

Yeah I was pushing it. I will raise it to $40 for 2 fans. Hopefully 3 if possible.

Just sayin' physics says he amount of air 212 EVO blows is air that was in said case previously. So what you might have is a case of negative air pressure, where basiccly there is more air coming out from your case then there is coming in. As such air keeps trying to get into your case, which ain't good since it's going to go throught cracks and holes where there are no dust filters.So yes, get three fans and reverse your setup to have 2 intakes 1 exhaust so you'll have positive pressure. So air's going to be coming out of every crack and holes in your case.

Well they are 120mm but you get five of them for 20 bucks

if you can go for around 20/fan get the Fractal Design Venturi HF-12/14 (120/140mm respectively)

Okay, I have a 140mm side fan that blows in and a front fan blowing in, with one exhaust.

How about half the price for 2.5 times the fans?

My case only has 3 case fans. One exhaust (120mm) one front (120mm) and one side (140mm).

Does the 140mm support 120mm fans?

No and its for cooling the GPU.

Darn. I would look into the fans that normally come with the fractal design arc mini. The fans are fractal design branded fans, they are quiet and they move fair amounts of air. They are also pretty low cost.

Basiccly you need (not need as in absolutly, but, ya know, less dust more air = win) more fans doing intake then fans doing exhaust.My terminology ain't right tho, so pls don't quote me.

Remember, you need positive air pressure,
This is because as the air builds up, the air has to escape so it will escape from the unoccupied holes in the case, like unused PCIe slots, air vents beside it and some other places as well.
Try examining using an incense stick of some sort.
