How practicle are two rads in a case?

post #1 of 8
Thread Starter 
Reason I ask if because I have a Define R4 case. According to different posts, in order to cool both my CPU and GPU, I'd need a 320 rad. I just got this case, and I can' fit a 320 rad on it.

But there are two places a 240 rad can be placed.

I don't plan to overclock my CPU much, I just don't need to. So I'm doing it more for the quieter sound, and better temps. With my Hyper 212 EVO I idle about 42, load max of 55.

My GPU is a 6950, OCed to 985/1415 it hits about 73 degrees.

So really all I'm cooling is my GPU, just with the CPU in the link.

So based off this, do I NEED two rads, or will one 240 rad be fine? If I needed two, I'd be mounting one on the top, and one on the front.

I think you could get away with just a single 240mm rad, but don't expect the best temps. It really would be worth while to get 2 rads since you are already spending a fair amount on blocks/pump for the system, so I imagine you would want it to work as best as it can. 2x240 rads should be good for your system even if you want to do some heavy OC'ing.

Depends on your airflow aswell. If one rad is just dumping heat into the other and reduced performance will ensue.
I personally use a 240 and 120 radiator connected to each other. Seems to work just fine.

You can always try 1x 240 to check temps add the 2nd one in there if there's a need. I imagine it'll cost you a little bit of tubing + extra shipping at most; nothing too expensive.

A 120 attached to a 240, please explain what you mean by that.

In my loop I have a 120mm radiator that dumps into a 240mm radiator- just inline.

Ah, there isn't much of a price difference between a 120 and 240 is there? Whats the point of just getting a 120?

I ran my CPU and GPU off 1 60mm 240 rad for several months with perfectly acceptable temps. You'll be fine with 1 240.

I think it was $20 diff, so yea not much
I thought it'd be cool to put my computer in a 4u server case- having a window on top to see everything. (though it takes alot of table space) A 360 fill fit along the long edge, but it was hard to find an enclosure to bolt to the case. I could fit the 240 on the long side and the 120 on the inside of the front of the case. I used the ex240 which is a slim radiator and an rs120.
