4-Pin Power Distribution PCB to Fan Controller

post #1 of 7
Thread Starter 
This may be a dumb question but I'd feel better with some clarification.

So in my new build, I will have 2 radiators, each with 6 fans. I want to connect each set of 6 fans to one channel of my fan controller. I'd like to connect the 6 fans "locally" to this http://www.frozencpu.com/products/14094/ele-936/Phobya_4-Pin_Power_Distribution_PCB_6x_3-Pin_Block_81097.html#blank and then connect that guy to the fan controller using this http://www.amazon.com/3pin-power-4pin-molex-adapter/dp/B000H25PBK/ref=sr_1_3?s=electronics&ie=UTF8&qid=1372350299&sr=1-3&keywords=3-pin+to+molex

Will this work? Will the fan controller be able to control all the fans connected to the PCB? In the past, I always used 3-pin wiring harnesses that had multiple 3-pin connectors, but this PCB seems like it'd be a lot cleaner. I'd attached all 6 fans to the PCB, close to the radiator, and then have only 1 wire from the PCB to the fan controller, opposed to the messy 3-pin wiring hardness

Not a dumb question.

Yes that should work fine, I've noticed similar ideas used before.

What this guy did in this build http://www.overclock.net/t/1314621/build-log-switch-to-caselabs-sth10-dual-loop-5-radiators-x79-tri-sli-680s/20#post_18392871

is that he used the distributor block and then just used a female-to-female 3 pin connector


and connected that to his fan controller. It worked awesomely

So if I have, say 5 fans, hooked up to the distributor block, and then use that female-to-female connector in the 6th slot and put that to the fan controller, it'll essentially put those 5 fans on the fan controller channel? In that case, I would need a block with 8 connectors (assuming they don't make ones with 7 haha), 6 for my fans, and one for power

Yeah that's correct.

Just remember to make sure that the wattage of your fans combined doesn't exceed that of the connector on the fan controller (or just use 2 blocks on 2 different fan controller channels)

If I knew about the distributor blocks before buying a bunch of y-splitters I would've done it myself smile.gif

Thanks! and yeah, I specifically bought a new fan controller because I need more wattage. I have a 30w per channel controller now, and the radiators will have 6 yate loon medium speeds. So that's about 22 watts for each radiator/channel (yates are 3.6w I believe), which leaves enough headroom.

Nice! Have fun - nice build in your sig lol

Thanks, will do! If you're bored, check out my build log here. Probably be a bit inactive until August
