Case airflow with watercooling radiators.

Recommended Posts

Posted · Original PosterOP

Hey peeps,

 

I have a corsair 900d, I am going to setup the radiators on it after the yearly maintainance soon so I wanted to find a few things about case flow. I am using noctua fans with low noise adaptors as well as 2x 480 EKWB XE radiators. I was thinking of placing all the rads in as intakes for positive air pressure. Is that a bad idea?

 
Cheers :)

It should not be any problem but do you have other fans for exhaust? Because the question is: Air will enter your case but how will it exit it without staying inside too long and get too hot?


If you want an answer, just tag me or message me! ^^

Since the beginning of time for 99% of all use cases:

Airflow in general

1. Intake front and bottom.

2. Exhaust rear and top.

3. Filtered Intakes

4. Positiv preassure

5. The End

You case and setup is not in the left over 1% category :-)

I have one 140mm fan exhaust at the rear near the motherboard IO.

I had exactly this setup but I had horrible dust buildup in my system despite using filters and everything. I had 2x 120 intake at the front, 4x 120 on the side panel side of the basement all for intakes, I had 2x 120 at the far side of the case, 4x 120 at the top for exhaust and the 140mm fan at the rear for exhaust. The intake fans spun faster than the exhaust fans for positive pressure but it didnt seem to work :P. I want this to be absolutely perfect as I have no willpower to take apart my system for another year or so... custom loops are very annoying to maintain :P
