Define S fans

[bart69132]

I know that the define s (windowed) comes with 2x GP14 140mm fans included, just wondering whether i should get another fan to have 2 intake at the front and one at the back for exhaust?

1 in 1 ex or 2 in 1 ex are both fine, depends on what you're trying to cool

 

alternatively you can use your psu as exhaust, though its not recommended that you do

Well for just now its a 6500 with an m9i, I'm waiting to get polaris gpu.

if you opt for open air design, mid-tier cards are fine with 1 in 1 ex

but if you opt for blower style cards, 2 in 1 ex might be best to achieve positive pressure

 

i would go 2 in 1 ex anyway, run 1 intake at low rpm during low load and ramp up the other two fans when gaming

I won't be getting a blower type card, unless it looks nice and since the wattage on the polaris gpu's under load is so low, it would be fine i think.

 

Okay, are the included fans with the define s good?

 

Also, what is the difference between positive and negative pressure, the only thing i know is that one of them makes the pc a lot dustier? I could be wrong since i really don't know much about it.

the included fans gets the job done, like any other stock fans i suppose `-`

 

positive pressure = less dust

negative pressure = lower temp <--- though i dont see how this works

neutral = hard to achieve, but theoretically the best

 

i would recommend positive pressure but near the neutral pressure line

Okay thanks

 

One more question, a stupid one. How do i know what way the air is moving through the fan without having power to it? I assume you can tell by the sticker?

normally the air will exit the side with the fan hub (the side with sticks connecting to the middle)

some fans have arrows on the fan hub to show the way the blade spins and the way the air flows
