800d, water cooling, airflow

[Huigie]

I'm going to transfer all my stuff from the LianLi PC70 to a new 800d.

Rad has 3 noctua fans on it. Problem I have now is that my rad dumps hot air in the case. Rad on top, fans beneath pulling air into the case. Gtx690 and cpu are watercooled.

 

In the 800d I want to change that, air through the rad out of the case. To level the in/outtake I reversed the back fan. This way I have 2 x 140mm getting air in and 3 x120mm getting it out.

 

Q I have is(i'm sorry)...push or pull. Rad is restricted, fans are high pressure.

 

I have no idea. :confused:

Pull is better than push. Push makes more noise, push/pull makes even more noise with only a small difference in improvement. Pull is a more natural way of pulling heat away from a radiator. Just like your car.

Push makes more noise, good point! I hate noise hence the water cooling. Will place the fans on top the rad, make them pull air from the case. Thank you!

One test on one type of fan doesn't mean anything. There are many types of rad and fan designs which contribute to different results.

for best cooling it should be pushing thru the rad into the case

Case design is also a factor for that as well, as some PC cases extract heat better or worse than others.
