I prefer distilled + pt nuke. I dont like the idea of adding different metals to the loop if I dont have too.
Okay, so you are getting the top rad (UT60) and the top fans (Scynthe GT) but in the end to be honest, there is not a huge difference between rads when it comes to performance. I mean, look at this graph
again but dont zoom in. They are so close together that you can barely distinguish any difference. They all pretty much are in he same clump.
What matters the most is air flow and the quality of your air. So here's my views on all this stuff. Others mileage will vary.
First, absolutely no rad sandwiching. And by that, I mean that all your rads in your case have to be either sucking in air, or blowing out air. If you have one rad sucking, and the other blowing, the sucker is pushing it's warm exhaust into the blowing rad and that's bad. Your blowing rad becomes almost useless. So all rads sucking, or all rads blowing.
Bottom should suck and top should blow. Otherwise, you might be recycling hot exhaust back into your case again. Not good.
All cases with fans installed have the bottom sucking and the top blowing. There is a reason for this.
Filters: they are a toss up. If you don't have them, you will end up with rad fins covered with dust. This is basically a layer of insulation on your fins, not a good thing. So either loose performance from dust accumulation on your rads, or face having to strip and clean your rads frequently.
But if you do put filters on your rads, that adds restriction and your fans have to work harder and this results in more noise or reduced performance. Me, I would only use filters on the rads or case fans that are sucking air in. And if I put filters on my rads, I would prefer the rads to be in push/pull to compensate for the added restriction of the filters. I am trying the demciflex filters on my next build. I only hear good things about them.
Proper suck/blow ratio: I have seen builds with 3 large rads all sucking air into the case an only one or two punny case fans blowing air out. It's clear here that the rad fans are trying very hard to breath air into the case when only 1 or 2 fans are blowing out, so the rads are essencially starving for air, and so is the case. This is like asking you to take 3 deep breaths in and only one short breath out. Do this for 5 minutes and you will blow up like a blow fish. LOL
So keep a good balance between your fans in and fans out. You will have to play around with fan speeds and fan directions. If you have filters on, it's a good thing to have positive pressure, as in more air in than air out. But don't overdo it. Just a little positive pressure will do.
Now, I know it can be tough to implement all the rules above in a single case. But I really think these guidelines are far more important than any decision on rad/fan/block/pump you select.
In fact, if you have bottom, front, and back all fans with filters sucking in air, and only a ST30 240 in push alone up top blowing out. That would outperform ealily a UT60 in p/p sucking and a UT60 in p/p blowing.
Most guys here seem to wave off these guilines too easily and would rather argue about fin count per inch or rad thickness until the cow come home when that is not very relevent in the end if the air flow is not optimized.
Design a good airflow, and the rest is just icing on the cake.
