I use the hardware.info roundups below. They test hundreds of 120mm and 140mm fans at: 12V+radiator, 7V, 7V+radiator, Airflow@30dB(A)+radiator. In their "comparison prices section" you can even compare fans and see the individual testresults from these tests, it is quite handy.
I used "Airflow@30dB(A)+radiator test" to select fans that are inside a case like the Intake-fans in a p400. Fans on the outside of a case I selected from the "7V (no radiator) test", because I want them to be silent as possible because I can directly hear those going about (exhaust fans normally do not have dustfilters, so i chose to select it from the list without a radiator). By selecting fans in this way, I can choose the best fansetup for me. Most of the time Be-Quiet and Scythe are2 or 3 times cheaper then a fansetup from noctua or Noiseblockers. Although both brands have awesome fans and packaging, performance in most round-ups is nearly identical.
If I look at the hardware.info 120mm comparison table
or their 140mm comparison table
I can even find maximum powerdraw at 12V under these testconditions.
Exhaust fans = three 120mm Scythe Slip Stream 120 DB PWM = 2.1W@12V each
Intake fans = two Scythe GlideStream 140mm = approx. 2.1V@12V (this powerdraw i took from the slipstream 1200rpm pwm fan, if vertically mounted i prefer sleeve over ball bearings)
With 3 pwm headers on my mobo, I do not think any problems will occur, until proven otherwise ofcourse.In general
What I like about 3p setups is that it is alot easier to select fans, because you can see how much noise they make under certain conditions in comparison to other fans (like in the roundsups above). If we use those fans at a fixed rpm, then we know prehand how much (or less) noise it will make. It should be (nearly) silent and you can basically not screw it up, noisewise. But the drawback is that noiselevel is not the same as the temperature of components. It is the automatic controls of fanspeeds when heat builds up, that I prefer, just to be safe. That is why i prefer pwm in this example of the p400(s) case.Casechoices
The Enthoo Pro M Acrylic is a really nice case, but is 56 liters and costs 85 euro. I liked the 65 euro pricerange where atx cases are around 35 to 45 liters, the p400 and S340 are big competitors here (both have alot of descent reviews). But in multiple reviews I read that the window on the s340 gets scratched even when you wipe dust of it with some cloth and same goes for the painjob. The p400 does not have the same negative experiences mentioned, which indicates to me that the case should have a slightly higher quality finish and materials used. DANG!
I still like the p400s because it has some soundproofing, but having a button in sight which i can not use if I choose pwm fans is a bit "mister-bean-like". So, I will go with the p400 and if the noise from the harddisks is annoying me, then I will buy some industrial A-grade soundproofing (I do not believe that the quality of soundproofing in the p400s is A-grade quality for only 10 euro more). I think Phanteks p400 and the p400s are fine cases, probably "best bang for buck" around the 65/70 euro pricerange because of the higher quality of materials used, even better then the s340.
p400 and pwm fans it is!
Thanks everyone, my apologies for having problems explaining my doubts and questions in this topic. Thanks again!Edited by Scoobydoobydoo - 8/27/16 at 3:24am
