How important is the Radiator? - Page 2

post #11 of 22
You're right. 0.45C is a negligible difference. The difference is more pronounced at higher or lower speeds, but around 1400rpm all the tested rads tend to perform within a degree of each other.

When I say best I mean the radiators that are capable of dissipating the most heat. Thick, high FPI radiators like the BI GTX, or Thermochill PA series. Where these radiators shine is high rpm fans that have high heatloads applied to them.

But those aren't the best if the OP is only planning on using fans running at 1k rpm, are they? Some people WC for quiet. "Best" is relative.

It's all subjective. Some people choose to run quiet fans and some choose to go for the lowest temperatures possible and care little for noise. Different radiators are appropriate for people with different tastes, same goes for fans, and essentially every other part of the computer.

This. But unless you want your computer to sound like a jet engine, your better off with low fpi radiators like the rx series.

IMO the rx series is the best "all around" radiator. It is not the best performing, but with my fan setup, it is the best for me.

Obviously you can cool better with higher speed fans, I am mainly looking at 1000rpm performance numbers.

At 600rpm, the numbers get closer together rather than further apart. The MCR320 trails by 0.21*C

I was looking at these tests to pick a radiator but I can't justify spending $30+ for less than a degree difference in temp.

At this point, I still feel like I am misinterpreting the results... For example, the difference between the PA120.3 and MCR320 at 463w load and 2800 rpm fans is 0.81*C?

Thicker core rads have more cooling capacity. You will run out of capacity with a thin rad before a thicker rad.

Would you run FOUR gtx 480s on a Swiftech mcr320 or a RX360/GTX360? Yeah, the more blocks you add the more a thicker rad performs better.

Assuming a required level of performance of a 10º Delta, there is little difference between an MCR and RX as far as headroom. At 2800rpm, the difference is ~42 watts and it only decreases with fan speed. Both are able to handle 3 GTX480s and not four... Same with the PA120.3, three but not four...

The GTX360 is a different beast, however. It has a specific market and one that I am not interested in...

why not avoid this conundrum all together and just use 3x BI GTX 560s?
