2x120 vs 240 rads?

post #1 of 6
Thread Starter 
So I have been very interested in watercooling and have been playing around with some ideas. But this one I want to run by you guys. Alright so as the title says 2x120 vs 240 rads. What I mean is it better to have 2 120 rads or a single 240 rad?

And just to rattle your brain if I were to wc with a 360+240 rad could it also be considered using 5 120 rads? As anyone played with this idea? I dont know the ins and outs of a radiator so any input is helpful. Does either one way you wc have a better temp results?

Hello,
This all depends on the thickness and DPI.

Each radiator you add to a loop is going to decrease your flow rate a bit (because of increased restriction), the exact amount varies between radiators. Generally speaking, you're better off using fewer radiators to maintain a higher flow rate, though if you have enough pump power it should be fairly moot. As far as cooling performance is concerned, assuming you're looking at the same brand/model, there should be little to no difference in the performance of two 120mm radiators vs a single 2x120mm radiator, if the flow is the same.

Thanks to both of you, that kind smashes that weird idea. I guess Ill go with the traditional 2x120mm rad to prevent any flow problems.

What else were you planning on running in the loop, what radiators, and what pump? If it's just a single block and a decent pump, you shouldn't have any flow problems with two 120mm radiators. I wouldn't consider anything like five radiators without some serious pump power, but running two 120 rads shouldn't be any worse than running two 240's or a 360 and a 240, something many people do with a single quality pump.

I just had this crazy idea on a build but I need to refine it before I show people because its pretty stupid atm so Id rather get the mechanics part figured out before I go farther.
