Need a PWM Splitter that can handle higher amp/watt fans

post #1 of 7
Thread Starter 
Hey guys. I'm looking for a way to split the CPU fan PWM plug on a mobo through a controller, that can handle higher watt/amp fans. I don't have a 5.25 bay slot available nor do I want to use one for only two fans. So this needs to be something internal inside the tower or something that fits in a PCI expansion. Any ideas? I remember a bunch of stuff like this back 5 or so years ago... but I don't see it anymore. I thought Frozen CPU would most likely sell something like this but I'm having a hard time finding anything at all. I could really use some help. frown.gif

Swiftech 8-way PWM splitter with PSU power connector

Gelid 4-way PWM splitter

Akasa has one as well but I don't recommend it. They connect 5 wires to single pin and than heatshrink behind that.. wires flex at pin and break.. you do something on system close it up and boot.. guess what a fan isn't running at all or it's running at 100% mad.gif

Damn... everything requires a 4 pin fan connector. Is there anything that uses a typical 3 pin fan connector? Unless someone knows of a low rpm delta... say around 120 CFM with a four pin PWM connector?

That first one by switftech looks familiar. I guess when you're used to everything being more difficult than it should be, you forget that sometimes there are simple solutions for things. I think I may have overlooked something at frozen CPU.

I need to rethink this.... cause I just realized something. lol

Haven't been feeling well lately and its making me loopy.

PWM has 4 wires:

Blackk = Grd
Red = 12v
Yellow = RPM signal from fan to motherboard or GPU PWM header
Blue = PWM signal from motherboard or GPU PWM header to fan

The Ground and 12v leads can be supplied from PSU molex or sata connection to fan

The RPM and PWM leads go between fan and GPU or motherboard PWM fan header.

PWM is the controller.

Your suggestion uses motherboard for power which is limited to about 1amp. That is the reason Thermalright includes a PWM splitter with molex power connector with Silver Arrow SB-E Extreme for the TY-143 fans that are rated 0.6A each.. 1.2A / 14.4w for 2 fans.
They also say:

*Only use the included PWM Y-Cable when plugging two TY-143 to the same PWM socket. Do not use third party Y-Cables.
