IT Diva, I just wanted to thank you for this build thread! I have a 630 that I want to start modding and I was trying to figure out if I could get a SR-1 360 in the top!
Just out of curiosity, have you ever run a similar fan/rad test with any of the Noctua fans
? Yes, I know they are ugly, but I have a few lying around from a previous build, so I thought I might use them.
No, I have not.
I tested only fans that I thought had a good chance of being good performers, And, that to my eye, worked aesthetically for the builds.
I was looking for the best ones of the ones I would be willing to use.
I also wanted to get some idea of how a pair of 25mm fans in push-pull compared to a single 32 or 38mm fan. Keep in mind that I kept the 32/38mm fans to models that could still be considered to be within a somewhat reasonable dB range.
While a pair of the best 25mm fans would loose big time to a 5000rpm Delta, even the 3000RPM UltraKaze, which stretches my sound level tolerance, doesn't out do a pair of the Prolimatech Aluminum Vortex fans on a fairly high fpi rad with less noise.
Also keep in mind, that Martin strives for actual numbers, where my tests were strictly comparative, and on the rads that I was going to be using, so trying to take away any generalizations may not be particularly valid.
My tests also only looked at air flow thru the rads, I have no way to know, from such simple testing, where the point of diminishing returns for each of the rads is, relative to airflow thru it, but more can't reasonably be worse than less, so I went with what flowed the most air.
From their history of performance on big air coolers, the Noctuas would probably be best suited for the thinner or lower fpi rads, where very low noise operation is the goal.
