Airflow help for new watercooling build.

[jfrech14]

This is how I have it planned out. Excuse the rough drawing. This was my fourth draft while doing it at work so it is a quick sketch and crossed out a few things. Let me know your opinions on the flow design. I made sure this would give me positive pressure but the only problem is the hot air from the 360 radiator being pulled in but the fan on the right should blow it towards the exhaust. The exhaust is a corsair AF 140 and the middle fan is also a AF 140 but the quiet edition. The 360 rad has the xspc fans and the 240 rad has corsair SP 120 PWM fans and the front are 2x140 nzxt fans. I have a ram fan on top of the ram so I used 45 degree angles on the cpu block to give some angle but not too much to hit the ram. The 360 has the benefit of bringing in cold outside air (I have a dust filter up there) and the 240 has the benefit of having cool air from the front fans. I am just worried about having the hot air from the 360 sitting in the case but maybe it shouldn't effect it too much since it is getting cold air from outside. Is it possible to have the left fan on the 360 rad exhaust right next to the 140mm exhaust fan and the other 2 fans of the rad bring in air? That seems plausible but not sure. Thanks 😄

So I shouldn't worry about the warm air coming into my case and warming up my NB/SB/Mosfest etc since I am passively cooling those not putting a waterblock on them?

The air passing through the radiator won't heat up… the temp change won't be more than 1-2C, at least should not be more… - if it is then something is not working properly…

Well, that ^^^ when you have enough radiators in the loop… in your case is pretty borderline though… - if you will push those two 770s, then actually the temps may go pretty high… which in turn will limit your CPU's OC too…

But hey, you will push your system until the temps will permit anyway…

And for that level of OC you don't need to put water blocks on your motherboard… the airflow from the radiator(s) most likely will be enough...

If your gonna use antro's graphic then no it shouldn't be an issue as the triple intake up top will blow air down onto the vrm and the double intake on the front will push the air right across the chip set, then your one exhaust will pull the air out the back of the case

As for the temps you saying warm air I'm guessing your meaning the air being warmer after it passes thru the rad, shouldn't really matter probly only a 1-2c difference then you'd see if they were just intakes without the rad

Not to mention down the road a ways you could always find a spot within the case to throw an extra fan to ensure the air keeps moving in the case and to add extra airflow over the vrm or chip set but only if u feel you need to really you should be all good

Also ek water cooling does makes blocks specifically for the maximus boards so down the road you could always grab some of those up but again only if you need to or if u want the bragging rights to say u watercooled the main board heat points

are you planing on adding a fan controller of some kind to controll the fans??
how tick are the rads?
if you have 45mm ( top ) you can do push/pull ( i had on mine ) but 60mm no go on push/pull only push or pull.
i had a 360 top and a 240 bottom ( both 45mm ticknes and only had CPU under water ) both was in a push/pull setup.
if you are planing to push those cards i would go for fans whit high static preshure, and good exhaust ( more then one exhaust fan so it does not become a to high positive preshure inside the case ).

The Setup I am doing is in a Switch 810 by NZXT. 360 Rad up top with the XSPC fans on top pushing through the radiator that is on top inside the case (Fans will be in a 3 to 1 connector to the motherboard (Believe those are only 3 pin). A corsair Air Series 140mm high performance fan with full control. The bottom Radiator will have 2 Corsair Air series SP 120mm PWM Performance edition fans pushing air in from the bottom. The front will have 2 Corsair Air series 140mm quiet edition (I think) fans pushing air in from the front and my HDD cage will have a 140mm fan pushing air across the motherboard towards the exhaust. My worry is building up too much hot air inside the case but with so much air flow hopefully it will find exahusts which is why I asked if maybe I can turn the left fan on my 360 rad into an exhaust and have the other 2 as intakes. That way I have 2 exhaust fans but my 360 rad still has 2 of the fans bringing in cold air but only one of them using case air which will be a bit warmer (I don't think too much warmer no?) But I am putting a drain valve at the bottom rad so I think it will be nicer to have that one remain a push intake so that the fans don't mess with the drain hose and so I get nice cold air coming in. I have filters on all intake holes and have filters available for just about ever opening so dust is not much of an issue in terms of where I put my intakes/exhausts but I feel like that is thermally my best solution since cold ambient air will be more advantageous than have the slightly higher positive pressure in the case. But I am seriously considering making my left 360 rad fan an extra exhaust. Maybe I will do some burn in tests in each position to see once I have it all set up. I have an inline liquid temp sensor where my drain port will be so yes the drain port will cause a little turbulence but I have 2 D5 pumps so it shouldn't be bothered too much since I will have very straight lines. I am anal about straight, clean lines. Also I am using the XSPC FLX hose... I planned on using a kill coil but what should I use to prevent the haze buildup? With this drain port I think it will be mest just to chance the water several times a year...

This is what I ended up doing. The extra fan on the radiator is just because I had it and was hell bent to use it and the ram coolers the same thing except mostly to try to move air around the cpu. Gonna test to see if it helps and chuck it if not. It makes the case look overly cluttered. Got some cleaning to do

Well I must say its very good that you are thinking about these subjects!
Making a drawing is generally the best way to map your ideas.

As for the design of the flow, I think your design will do the job!



I think my build is setup in the same manner:

I have experimented with the fan directions, but this has proved by far the most effective.



My other system has an other way off controlling the airflow:

Both systems are being cooled by the loop very well.
