Which fan / how much static pressure is needed for a 11.4 FPI 420 rad?

post #1 of 8
Thread Starter 
Hey guys, I've decided to go with a Alphacool NexXxoS XT45 Full Copper 420mm rad which has a density of 11.4 FPI. I've seen rads with 5-7 FPI and also rads with 20-20 FPI, so I would assume that the 11.4 FPI of the Alphacool is a balance between high air flow and surface area.

What I've learned that if a radiator has low FPI, it can do with lower RPM fans, but my question is how much static pressure is needed for that particular radiator, or any rad with a similar density.

I've looked at the Phobya Nano-G 14 PWM Black Silent Edition fans which has up to 1.85 mm-H2O static pressure, but is that a bit overkill for that density?

I'm looking for black or white very quiet fans which are going to be hooked up to a fan controller. Oh and I'm going to have at least 10 of these fans in my case. (6x 140mm for a 420 rad, and 4x 120mm for a 240 rad).

I should probably mention my specs for anyone wondering. Let it be said that I'm only looking for an overclock at around 4,5 Ghz on the CPU and the GPU's isn't going to be overclocked any time soon, just want a silent and cool system.

Intel Core i7 3820 @ currently at 4,2 Ghz with a Noctua NH-D14
Asus Rampage IV Extreme
MSI GTX680 Twin FrozrIII factory OC
And my case is a NZXT Switch 810 Gunmetal

Thanks.

Those are beautiful! I see that there is a 7 volt adapter, are they able to go lower than that with a fan controller without shutting off?

The FPI on the Alphacool UT45 radiators does not require a high static-pressure fan and any good fan will push through it without any real issue.

Noiseblocker NB-eLoop @ FrozenCPU (or at PPCS) is a pretty good fan that is extremely quiet, expensive, but probably overkill for your needs.

Edit: Corsair Air Series 120mm and 140mm fans are also fairly good. They are black and the color rings can be recolored (one of the rings is white).

Also, the Cougar fans are pretty good as well. thumb.gif

But, won't low static pressure (0,8) mean higher RPM? Higher RPM means more noise.

I mean, isn't it better to run at 600 - 700 RPM with a high static pressure fan than at 1000 - 1200 RPM with a low static pressure fan?

Just go by the highest static pressure with lowest db rating. 600-700rpm is to slow for me I like them around 1000-1200.

When you got 10 rad fans in a case, I'd like them to be as low RPM as possible while still be moving some air though. So 6-700 RPM is low, yes but that's when I'm not gaming and stuff. As I mentioned I'll have a fan controller so I can turn them up to 1000 - 1200 RPM when I need to.

I would pick up the best fan then if silence is a big goal. Keep in mind some companies tend to misrepresent their fan specifications so approach them with a grain of salt. wink.gif
