32T or MCR320-QP w/ high cfm deltas?

[johnanderson]

So which one is better with high cfm deltas? I have two 130cfm and one 150cfm delta and I'm wondering which rad will perform better if I crank them up to full. I know the 32t is thicker but IIRC the mcr320 is longer. If they both perform about the same with these fans then I'll probably just get the mcr320.

Both radiators are considered to be about equal in performance, the MCR's having a slight leg-up.

However, both radiators are designed for low CFM fans, so you're waaaay beyond the ideal spot on an exponential performance curve.

Well, I had the fans anyways so I thought I might as well use them. Ideally I would want to get the thermochill he but I cant seem to find one around anymore or the prices are basically the same as the pa series, which is more than I want to pay for. So unless someone can recommend me a 3x120 rad that uses high cfm fans and performs better than these two at the same price range then I guess these are my only choices.

Oh, I forgot to ask, what about the Black Ice GTS series? I know they have higher fin density but theyre also a bit more restrictive. Any recommendations for getting this if I can crank my fans all the way up?

[TheJollyFellow]

again, the performance difference between any radiator at the ~$40-$50 price range is going to be hardly noticeable with high CFM fans. Most radiators are optimized for low-flow fans, meaning performance will increase only slightly (and probably not noticably) as you increase from say 20-40cfm to 70-150cfm.

The GTS series is along the same line as the MCR's, only more expensive.

Get the triple MCR radiator, and put any fans you want on it--it's the best bang-for-your-buck, and can work passively if you don't put too much heat into the loop.

Well, I just found this chart, which puts all those rads I'm looking for within the same performance range. It looks like I'm going to be getting the 32t, but does anyone know if they still offer it in the 18fpi config since most of the ones I've seen around are the 12fpi config. Also, does anyone know where to buy them. They seem to be sold out everywhere.
