Hi all.

I am wanting to dive headfirst into the world of Watercooling and I have spent a considerable amount of time trolling the stickies and links to fill my brain with all that I can. I feel like I am lacking heavily in the fan knowledge section. I know what all the important variables are, CFM, dba, Pressure, etc. But I don't know where I can go look at a list of these to compare and select what I want that would suit my needs. I would love to be able to just use the cfm vs dba given on the websites... but we all know that is just a bunch of :blah:.

Here is an idea of what I am wanting. I want to run high fins per inch rads in my loops, so I know I will need some good pushing fans. I am planning on using Diggr's in process guide to make shroud boxes for the rads. Ideally I would LOVE for this thing to run silent, :rofl:, moving on. I plan on making an arduino based controller for my fans, and I want them to operate normally at a moderate RPM that is pretty quiet but can scale up decently high as well. The thought of the super pushers, like the Nidec I saw in some of Seeb's videos... but at $100 a pop, I don't think I'll be outfitting my case in these babies.

i was wondering if there is a point where increasing CFM didn't show any more performance gains. Is there a chart anywhere that shows CFM performance based on fin density? I would like the ability to crank my system up to get only a few C above ambient, but I honestly don't know what kind of CFM requirment that would need. Would I be fine with maxing a CFM at 90? or would I need to push up to 150, or 200+?

Any and all advice and empartment of knowledge will be greatly appreciated! :rock:

I just realized this would probably be better suited, and seen in the Water cooling sub-forum. Any nice mods wanna move me?
 
I say go with the Gentle Typhoon option we talked about on PMs... :D.

You could get away with AP-15s and not need more powerful fans... There is a point where speed of the fan is not going to bring you any more performance (law of diminished returns)... I don't know where that is, but I can tell you that any of the beast fans (Nidecs, Deltas, San Ace, etc) are well past that point way before you spin them up to full rpms. But because I like beastly fans; if it were me, I'd go with the AP-31s for $5 more.... That gives you the option to do the PWM mod on them and then you have the 5400 rpm headroom for when you want to turn your computer room into a wind testing facility. :D
