More Radiator vs. More Fans

post #1 of 8
Thread Starter 
Hey all,

Let's say hypothetically I have a case with 85mm of space. Would it be better to have a 60mm thick radiator with a single set of 25mm thick fans, or a 35mm radiator with two sets of fans in push/pull?

well that is a interesting way of looking at it.
the simple way of looking at radiators, the thicker the radiator the higher the water flow rate through it will be. rolleyes.gif
a 360mm radiator that is 38mm thick or less with a low FPI(like 7FPI to 16FPI) and 3 fans at 2000RPM's, will cool the same with 6 fans at 2000RPM's
thicker radiators (like 42mm to 80mm thick) need all 6 fans on them to get good air flow through them. thumb.gif

go here and look at the thermal testing for many radiators, has push/pull vs push for thick/thin, so you can run through scenarios and see which performs better for given space.

These kinds of questions are very subjective. There are way to many variables at play to make an educated discussion. Best option is to follow opt33s recommendation. Look at the charts, apply your projected heat load.

From what I get reading that, it seems like push/pull is always better, even if I have to, let's say, use a 30mm radiator instead of a 60mm?

I did a lot of reading on xtrremerigs and it looks like the HWLabs Nemesis 420 and 280 GTX would be ideal for my application. Top performers in push or push/pull, and they're not terribly expensive.

It does look like the thinner radiators in push/pull are beating out the thicker radiators with just push, but not by much. In the 280mm size, it's typically 340W vs 365W or so. But the performance of the 280 GTX bumps it into the higher range. Plus, this would save me $ on fans lol
