Hi,
Majority of cases are open in the back so hot air is forced out
Room ambient air through a rad will be roughly the same as the water temp say between 25-35c

Most components heat way more than that
Just memory 40c oc'ed if you're lucky
CPU block crips 110c tj max oc'ed to death
GPU another heat producer on water 40c minimum oc'ed

Top intake directs air straight down
Front fans direct air straight back
With that why would you want to push hot case air through a rad ?

Alright, what I'll do then is set my top-mount 360 rad as intake. I have 3x140mm fans in the front, those will be intake as well. Bottom 120mm rad (for GPU using Kraken G10 universal mounting bracket) will be intake, as well as a separate standalone 120mm fan on bottom intake as well. There is one side-mounted fan that will be intake as well, and then one 140mm fan in the upper back as exhaust, as well as a separate 120mm slim fan in the lower back as exhaust (it's there for my hard drives to keep them extra cool). This should create a ton of positive pressure so any excess air should be pushed out the back and any other cracks.

For dual pumps you can either buy one that’s dual already, buy a new top for both or run them each separate. More run them in serial, one pump feeding the other as it creates more head, or you can run them in parallel and get double the flow
yay you didn't beat me to it.

then you forget where you are.

the parts are expensive, n people dream of scaling up.

people also dream of silent operation, while still overclocked = lots of radiators.

you always want your radiators pulling the coolest air possible, n said air is pretty much always outside the case.

even radiator wash is enough to keep most board components cool enough these days. If not? Zip tie a fan, or get a VRM block/southbridge blocks and go dual loop.

Both of my 280 rads are on intake. Plus I have an external 280 that also runs off ambient.

As long as you have airflow across your RAM and MOS you should be OK. I i have front and top on intake and rear on exhaust.

I have all rads as intakes, I don't even have an exhaust fan as it's not needed.

+1 top n side rads intake, front intake and rear exhaust. Here is a good review of intake vs exhaust for rads

Hi,
That is exactly what happens

If it were the other way outside air would be sucked through the cracks where there is no filter
Top & front are filtered with a screen but better than nothing

If you want added dust prevention use some speaker cloth or something behind the cases screen filters.
Otherwise just blow out the rads once a month or so depending on how dusty it is where you're at.

I have a similar loop in a 719 case and so far a single D5 seems to be working fine as far as I can tell. I do like the idea of dual pumps so you have a backup just in case and also since you can run them at a lower speed.

I currently don't have a flow meter installed so I can't provide any specific numbers on flow or temp. Waiting for the 3080/3080ti to be released and then I will add the gpu into the loop. 3600x will probably also be upgraded once the next gen of ryzen cpus come out.

I have all my radiator fans installed as intake with a 140mm fan at the rear for exhaust.
