Case Fans . 4 Intake , 1 Exhaust vs 3 Intake 2 Exhaust

Hi Everyone,

 

I have a nzxt kraken x62,AIO liquid cooler, mounted in the front of my case used as intake fans and 1 rear mounted exhaust fans.

 

I have 2 more fan slot on the top of the case. 

 

If i were to add more fans how should i position them? 

 

4 Intakes 1 Exhaust from the back?

 

3 Intakes 2 Exhaust ? 2 fans from the top 1 will be pushing air in while the other is pushing air out 

 

2 Intakes 3 Exhaust ? 1 exhaust from the back, and 2 from the top

 

Thanks

Positive pressure is probably best if you have dust filters.

And so intakes from front and bottom towards top and back. 2 in front,1 bot push conf. and 1 top 1 back in pull conf.

That also depends on positioning of you case, if you have enough room behind PC etc ...

Move AIO to top as exhaust, have 2 intake fans and set intakes blowing faster than AIO fans. Maybe filter rear, but you don't need fan there as it wouldn't change anything. AIO as intake is causing higher GPU temps than one as exhaust.

The back of my case is quite open. i do have dust filters just wondering how should i make it positive.  dont have a bottom case opening using a Thermaltake Versa J21 Tempered Glass Edition Mid Tower Chassis with a nzxt kraken x62

If you want better cooling, move the x62 to the top as exhaust and add new intake fans at the front. If you want fan recommendations, tell us where you're shopping / located and your budget.

The only benefit of positive pressure is to reduce dust buildup when using filtered intakes. If you're using the rear as an intake, get an aftermarket filter. Leaving it as exhaust or empty is probably better though.

Having it intake would not help for that. All air it would bring, would be straight out from top. Just leave it without fan and adjust intake fans to speed faster than exhausts.

How about this? He proved that front rad placement as intake gives the best balance temps overall..

I wouldn't use word "proved" there. He says right on beginning that this is just he's testing, and applies on that particular hardware and configuration. There are few things that could happened. Like having smaller case where rad is closer to GPU or the space between rad and card otherwise occupied. Also another open-style card could have different results. It is good test, and I would encourage to do own testing to find best results.

 

For this thread my points of having rad on top are rather based on what I've read over the years from forums as I'm air cooling guy. People with front placed rads have generally higher GPU temps than those who use top mounted.

Right.. I think that's where I will be going too.. Idk why I never get convinced and confenience to go liquid cooling..
