Mcr 320 + 220 > Pa 120.3 ?

[Darkatom]

Could you guys shed some light as to wether or not the MCR 320 + 220 combo is cable of better cooling than a PA 120.3 ( Plaaning on using Med. Yate Loons). In my case this would only be cooling a Q6600 only, I already own the MCR220 rad and was interested in going for a PA120.3 to be honest. But some recent threads have shed some light as wether the PA 120.3 is in fact greatly worth it over the MCR 320. I know that your paying for the cooling capabilites at low noise, etc. In my case im just interested in the end performance with reasonable noise, the amount a radiator costs is not the issue. Anyways the case im working with is a TJ07 (ofcourse) so storage is no problem.

Not sure about the reasoning behind your comparison since you already own an MCR220. Naturally two rads beats one.
MCR 320 + MCR220 > PA 120.3

But wouldn't a more sensible comparision (since you plan on keeping the MCR220 ) be as follows?
PA120.3 + MCR220 > MCR 320 + MCR220

Since you've said cost is not an issue, not sure why threads about whether a Thermochill is worth it are concerning you. Of course it's not worth it if you're on a tight budget and cost is an issue (and you're in the US). If cost isn't an issue that's all irrelevant.

A rough relation is one PA120.2 = one MCR320, sort of a 2PA=3MR ratio.
So using that generalization in terms of 120mm radiator sections, one PA 120.3 would be roughly equal to 4.5MCR using yate loons per the one test article I've seen.

So one MCR320 and a 220 would probably be slightly better than one PA120.3, but then you also need to consider space, noise, and flow rate. The PA series is the king of low restriction for flow rate, and running 5 fans over 3 will certainly make more noise.

So if you have the space, plenty of pumping power, and noise is not a concern..sure.

the pa120.3 is far less restrictive than the MCR series... which could be an important factor in your loop...

I guess my thinking for comparing the two was a bit off. I would have thought that "more" raditator was the deciding factor in cooling, but I guess that I didnt factor in flow rates, restriction and what not. I was just trying/hoping to justify not waiting for PA series stock to return to online stores. Now while typing this I begining to wonder between the following 2 options:

1) 2 x PA120.2
or
2) 1 x PA120.3 & 1 x PA120.2

I must say, the possibilites are never ending.

Are you joking? This is an even more silly comparison and you (and everyone else including people who don't know anything about watercooling) already should know the answer.

What is it that you want to cool?
you can see which rad you need here:

Here's an article by Marci comparing the PA series.
http://www.over-clock.com/ivb/index.php?showtopic=17958
notice the PA120.2 (with shroud) has a close performance to the MC320

(also shows the pressure drop - thermochill lowest as said before)
