Gelid Solutions 1-to-4 PWM Fan Splitter
If you want your motherboard to control the cooling inside your computer then Gelid's 1-to-4 PWM Fan Splitter could be what you are looking for.
Gelid's 1-to-4 PWM Fan Splitter allows the user to connect up to four PWM fans from just one PWM fan header on the motherboard. And because the fans are PWM the RPM of each fan will change dependent on the temperature of the CPU and/or motherboard BIOS settings, meaning the RPM and therefore noise will be reduced if the system does not demand high airflow.
The extra power required to run four fans from this splitter is provided by the 4-pin molex connector, which does need to be connected if more than one fan is used.
Cable has one motherboard PWM connector plus a 4-pin Molex connector for fan power
The cable has one PWM connector with fan speed signal wire which is connected to the first fan. The extra wire on that connector will feed back the speed of that first fan to the motherboard. The other three plugs can be used to connect three further fans but the motherboard can’t know what speed they’re running at, hence no need for the fourth wire on those plugs.

- Connect four PWM fans from one PWM fan header
- Molex connector for extra power
- Easy installation

I used one of these to power and control the CPU; two top exhaust; and one rear fans in a Gelid Dark Force case. Getting it all connected was very fiddly at first, but the second build was much easier.
What else can I say? It is inexpensive and it works like a charm. Think I'll buy a couple of spares in the new year, just in case they stop making them...
