Fan Splitter PCB?

[Lays]

I've run out of Y splitters that came w/ my Noctuas, and now I'm wondering if there's a more elegant solution to my dilemma.

 

I have 8 Gentle Typhoons, and 4 nf-f12's on my radiators currently, and a 6 channel fan controller with 30 watts per channel.  I'm planning on replacing the nf-f12's with 8 more Gentle Typhoons in push/pull on my bottom radiator, but I simply don't feel like getting 50000 more Y splitters to run them all at once (it's a cable managing nightmare with that many fan cables+ y splitters + extensions everywhere)

 

I saw some "Fan Splitter PCB" things on a video made by Singularity Computers, and was wondering if someone could give me some advice as for which one to use?   I'll have 16 Gentle Typhoon ap-14's and 1x 140mm of some sort in the rear soon. So a total of 17 fans.

 

 

Sorta like this, but I'm unsure if I need extra molex plugs on it or something? 

 

 

Any help would be greatly appreciated, thanks guys!

Swiftech has an 8 way splitter thingy http://www.swiftech.com/8-waypwmsplitter.aspx

I found a few on frozencpu/perf pc's but I have no idea where to even start..  

 

17 fans is a lot q_q

Get 2 of the nzxt grid's and get a 2 channel fan controller. Plug each grid input the the fan controller lead and then all of your fans in the the grid's.

Swoftech is only pwm. Also watts is amps * volts. Fans are 12v and their rated ampwrage should be on them. Once you figure out how many that is get a few splitter like the one you showed or the nzxt that can have that many plugged in.

According to Frozen Cpu an ap-14 is .083 amps, so 0.083*12 = 0.996   Each one takes 1 watt or so.

 

I'll scroll through and see if I can find a simple PCB one with specs etc, and go from there.   Tyvm    ( I like the minimalistic design of the plain PCB vs the swiftech "splitter box" )

I grabbed this pic from scythe's site

if that yours it actually 0.049A @ 12v

also link for frozen cpu: http://goo.gl/KNr6V8

That would mean that each is .588 watt, which I would just round up to 0.6 watt for safety purposes. That means you could have 50 fans without any issue. There are 6 channels so I wouldnt put more than 8 per channel.

You have 17 fans correct? Just do say 3 per channel or something like that. you could easily do 4 and 2 or whatever depending on say if you want one slider to be the front fans, one to be the top, etc. For 4 fans or less I would just get something like this http://goo.gl/kTq5EA . They range from 1<2 to 1<6 but I said up to 4 because you should say around the 3 if possible to balance the load and well any more than 4 is going to get messy quick cable management wise.

EDIT: Also if you get cables for the splitters I really suggest the phobya ones as they are wired correctly unlike many out there, only one of the fans that have been split off should be reporting speed. you could also easily make or modify a cable where the yellow wire to report rpm is broken off and plugged into the MB so yo actually know what rpm you set the fans at instead of some relative percentage on the slider.

Oops, I was looking at the 1850 rpm model.

 

 

I would do those Y splitters I'm just worried about it becoming an absolute mess like it already is, and I only have 12 fans now, once I add another 5 it's gonna be a pain. I figure with the PCB's I can just double-sided tape them to the back of the 5 1/4 inch bays, and route cables easier.

 

I was thinking about doing 8 fans on channel 1( rad #1 ), 8 fans on channel 2 ( rad #2) , then the 140mm on channel 3.  Then I'd have 2 channels for my icemodz LED strips that have 3 pin fan headers on em for power, that'd leave 1 channel open for future stuff. If I did it like that I could have a temp sensor on channel 1 & 2, and put it on the vrm's to use the auto-fan control my fan controller came with. 

 

The entire PCB would be controllable right? As long as it has a 3/4 pin "input"?

BTW did you see the EDIT? I might have been doing it as it as you were replying.

Which fan controller do you have BTW? A few running though my head are NZXT (3 models) and Fractle (1 model).

That would work too I just wouldnt go above 8 per channel. you may want to test the strps before doing that. LEDs cant so some voltage dimming but PWM is far better and has far more range for them. Though I don think I have even seen case LED strip controlled by PWM.

Yes just think of the "PCB" as a splitter. BTW the swiftech one is just a PCB underneath too they just added platic to protect it, make it easier to mount, and to look better. You only want some soft of splitter that is 3 pin as the 4 pin ones like the swift tech are PWM which get straight 12v and are controlled via delays of on and off. Also im pretty sure I know what your trying to do (see picture below), just make sure you have enough or long enough extensions. The cheapest ones on Frozen CPU, the non sleeved individual wires ones are a pain though so spring for sleeved ones you can.

It's a G vans Tactus, Phobya+ lamptron also make a version just like it. 

 

http://www.performance-pcs.com/catalog/index.php?main_page=product_info&products_id=37478

 

The LED's dim a little bit on the fan controller, (I previously had em on channel 5+6, but then added more fans to the top rad) but my favorite part about having them on the controller is I can turn them off when I sleep, without reaching into my case and unplugging the dam things.

 

Could I buy two 3 pin to 5x 3 pin PCB's, and hook them together with a Y splitter on 1 channel of my fan controller? 

 

I could get 4 of those, and plug 4 fans into each PCB, and 1 channel to each set of 2 PCB's. Then I could just use a Y splitter for the 2 LED strips.

 

 

I saw your edit just now, I'm not worried about the fan RPM since I know what % I need to turn them up to when gaming and what to put em at during idle/light browsing etc.

ok why not try this http://goo.gl/fLlLmn I know its two more than you need but it just might fit the bill? This http://goo.gl/72p264 should also work as its just a header on the one end, just dont use the 4th pin on any of the plugs.

Oo that second one you linked would work perfect. I didn't see it before in the list (I didn't scroll down far enough)

And it's nice and cheap too  I could get 2, and label one as "Rad #1" and "Rad #2" with a label maker or something.

 

Tyvm for all the help

NP I would just get all 3 pin cables for it though and ignore the 4th pin for PWM.

Glad I could help, there are few others with a fan fetish like I. That reminds me I think you have me beat as I only have 14 fans, 6x NF-F12 PWM and 8x NF-A14 PWM.

EDIT: Forgot the 5x NF-A6x25 that are controlled by the case's fan controller, that make a total of 19.

I could put 3 more as intakes or exhaust in the front panel, but after adding my drain plug I think I'd only have room for 2 instead of 3. So we could be tied I'm actually enjoying the temp difference at lower fan speeds of the push/pull on my top rad, it dropped temps like 5~ degrees at 40-50% fan speed, I can actually leave my fans there now, before I'd have to put em at 60-70%. Since it made such a difference I figure I'd put push/pull on the bottom rad as well.

 

I may have to change my top rad's fans to intakes instead of exhaust, my case is filling with dust extremely fast, I may need some-more positive pressure.

Dont worry 4 of those 5 fans are for looks

you should balance your air flow with a bit more positive if possible. Do you have fan filters, if not not amount of positive air pressure is going to help you.
