If you are getting PWM fans you would only need the pwm splitter the swiftech one.

I know that, but this controller would be like a "3-pin for 4-pin" converter, so any fan I buy could be a "PWM" fan, but still having the possiblility of turning them all 100% up anytime with no software hassle.

Search through the water cooling builds and you will see a lot of people running 3 cards and a CPU on a single triple rad. and things stay cool. For you having triple the surface area and it being all in a central location you could easily get by with 9 medium speed fans without a fan controller and just run them full speed on the molex connector. Less hassle and less electronics to worry about burning up.

I run my medium yate loons on full and I can't even hear them at all over the pump. I used to have a fan controller and it became useless after seeing very little temp changes from running them full or at half speed. The less electronics and wiring, the better. Fan controllers can look cool given some of the designs but to be honest once you have the sweet spot set you rarely touch the thing again. I was more worried about little fingers from my kid or bumping the knob on accident (both have happened) that I reversed my controller so the knobs could only be accessed from inside the case and put a faceplate on to hide that I even had one. The next cleaning I just took it out because it was on full anyway.

Lower speeds will draw less electricity and demand from your PSU and cool just as well as something that sounds like a turbine. Fans are designed to be run withing specific RPM's. Change the speeds with a controller and you need to do the math on how much air you would be pushing if that is the setting you would run them at. With that thought you may be able to get by with a lower fan speed/noise ratio from the start.

Most people believe that more is better and that you may just need that in the future. Unless you live in weather that is unbearably hot it's just overkill and only for bragging rights. And if you do live in an area that gets that hot you may have to consider just turning the machine off for a bit. I had a couple days over last summer where I needed to just shut things down for a couple hours.

I know that... The point is I just can't stay with the idea of buying 2 360mm rads (I don't want only 1, personally I feel more confortable with 2 or more) because of this simply equation: 2x 360mm rad = 2x $60 = $120; 1x 1080 rad = 1x $109 = $109. I would be paying more for something maybe less performing (I know the difference would be very very very small). And, unless the big radiator usage gave me a casing trouble, which is not the case (I would have the same dimensions on it with or without the triple 360mm), I believe it is the best choice, for now. But the bigest point is the prince, I just can't be happy with that said above =(.

Where is this mounted? side panel?

Also note, that two 360mm rads will only need 12 fans for a total push/pull config, that's 6 less than you would need for that 1080 rad.

And instead of water going into a single rad, it can cool down before each component, assuming you're cooling 2 or more items.

So rez, pump, 1st rad, CPU, 2nd rad, GPU's, rez. (not sure if that's correct)

Have you really looked into the specs and actual user reviews of the 1080 rad? You may have a lot more flow restriction pushing through that rad all at once vs. 2 360 rads staggered. This could lead to your pump burning out prematurely. If they increased the tubing size within the rad to adjust for the flow it may pass through quicker than it should. So many variables and opinions on this subject.

You obviously have your heart set on your design. Like I have said before, trial and error is the only way to go. Let us know how it ends up and please start a build thread with step by step pictures.

The loop sequence doesn't matter... The only thing that can't be changed is the res above the pump, and just for filling purposes.

Ok, thanks so much for all the advices you gave. As this thread is about fans and I have already made my choice, I'll continue the questions at THIS one. I'll consider the idea of using the 2x 360mm...

I know that...

PWM fans don't like being voltage controlled... they will complain, either by humming or singing or by giving up the ghost prematurely.

The little logic circuit which lives in the motorhub of a PWM fan expects to be fed 12 Volt (or for some other fans/brands 18, 24, 36, 48 or 72 volts)

I meant say the controller converts all comom 3 wired fans into PWM fans. But I'm going to use just the PWM fans, no more fan controller as I'm seeing them as unecessary.

I'm aiming for cheap fans...


Will go for the PWM Helix.
