Multiple Internal Rads: Intake or Exhaust?

post #1 of 21
Thread Starter 
I am going to be adding another rad to my loop. I already have a top mounted 360 with fans exhausting from top of case. If I put a 240 on the bottom, should I be setting it up to intake to the case to keep the airflow right, or exhaust to keep from dumping all that hot air on my board?

You're in kind of a Loose/Loose situation.

I would guess exhaust is better in your situation. Generally you don't want to feed air thru two radiators sequentially - ie sandwiched radiators, which I understand you're not doing, but the theory is the same.

That of course assumes you can pull fresh air into the case from somewhere else like front, back or sides.

I can't find the post, but it's been tested and intake seems to get better temps than exhaust.

I'd do intake on both. If you have decent fans, the volume of air moving thru the case will make little difference on your board as long as the air has a path to exhaust.

Got pics of your setup? thumb.gif

I would also make both rads intake. I will be doing the same for my build.

This is how it sits currently:





I have new tubing and anti-kink coils in a box from Frozen-CPU and a EX120 from Sidewinder waiting for my weekend. My plan was to put the new rad in the front, but.....

I am feeling another loosening of the purse strings, and am literally in the middle of talking the better half into a trip to Micro-center for a new case. If this comes through I will be getting one that will allow me to put the 360 inside as well as another 240 rad from another machine. I guess my new question is: Will the XPSC Pump from the Rasa kit be enough to pump CPU, 2XGPU blocks and 360, 240 and 120 rads, or should I add the Pump/res combo from the other machine and make 2 loops out of it?

I am leaning towards the NZXT Switch 810, but that does not have enough 5.25" bays for both dual bay res without loosing my optical...so if I go with 2 loops I would go with the Azza Genesis 9000 , which is my second choice.

The rasa pump should be fine for that. And for sure go with the switch 810. It's an amazing case for the price and you'll love it! Has plenty of room for what you need thumb.gif

you want both your rads set the same so your not putting hot air into the other one either both exhaust or both intake i have both my rads set as exhaust with a fan at the top and bottom of my case pulling in air for them.

Bottom rad should never be exhaust IMO. The heat just gets trapped on the ground under the case and then rises back into the rad. I suspect temps would be dismal, as you would not be dissipating any of that heat into the environment, but rather it would fall right back into the radiator.

lol thats why you have feet on the bottom of your case if you have a rad in the bottom if you have a bottom rad as intake then your putting all that hot air inside your case for the other rad to suck in.
