Radiator Fan set up Question

[smith87e]

Here’s my Question I have the ASUS Maximus V Formula and I have a 4 fans on my radiator that board has a 4pin CPU and a 4pin CPU OPT both of which I believe ramp up or down in unison. I can also control those two connectors with the Fan Expert 2. I’m deciding on if I should or have to get a 5.25 fan controller or I can buy a 5 to 1 PWM cable that has a 4pin Molex aux power and plug that into the CPU header and allow the MOBO to control the speeds in sync. eventually i will have 8 fans between the two radiators and plug 4 into the CPU OPT and 4 into the CPU header, if that cable will work its will help with not having anything in the 5.25 bays for a sleek look. do you think the cable route will work?

You can buy splitters for both 3 and 4 pin fans.

but will i be able to put 4 Pwm fan on one header if the spliter has a 4pin molex aux power

Huh? Why would you want to give it aux power?

If anything cut the "+12V" and "GND" cables in the splitter and plug those into the appropriate cables on the PSU.

this is the cable im talking about im assuming the 4 pin molex is there so that you dont fry the cpu header because of all the fans thats the only logical thing i can see it being used for

That would work. They probably did what I told you but under the sleeving pre-made for you.

or any of the chassis fan headers.. the Fan Control option works on all headers and gets picked up

on most major temp progs (OCCT, HWMonitor, RealTemp) ive set mine to low speed 50% @ 55°

high speed 100% @ 75°

depending on what fan, buy 4x 2-1 fan "Y" splitters and one 4-5 splitter and pair the fans.

SP120PE, Noctua NF-F12, Swiftech Helix 120, AP-15, Cougar 12H so far can run from one

fan header with no startup or controll ills.. thats 8 fans..

ive since gone molex fan support direct for 7volts and got 3° warmer at 100% load over throttling

the fan voltage..

Plugging multiple fans into mobo headers isn't a good idea, unless you make sure it can handle it beforehand, there is the possibility of overloading the header and burning it out. In some cases, this has bricked the motherboard. Though I suspect it would be fine in this case as the splitter incorporates a Molex connection for supplementary power.

If you want to power and control multiple fans from the one channel, IMO do it through a fan controller. The NZXT Sentry Mesh is a fairly good one, cheap and has enough wattage per channel to support I would say a max of 4 fans on the one channel (of which there are 5).

You wont get PWM control with the fan controller, but for rad fans you dont need it. You set it to a speed that's quiet and leave it there, if you have enough radiator space (particularly low FPI, slim rads), the fan speed doesn't really matter much.
