Is it safe using fan splitters to power multiple fans? I would presume there is a safe limit.

My system would have

Two 12cm exhaust fans
Three 12cm intake fans
One 8cm top exhaust fans
12cm and 14cm CPU fans.

What's difference between three pin and four pin fans? The two CPU fans I have are three pin. Is the fourth pin actual rpm sensor telemetry?
 
I can't see any maximum current rating in the motherboard manual

At most I'd run use a Y splitter (two fans off one) The motherboard has five fan outputs so I'd need a couple of Y splitters

That looks useful thanks, so two of those should be plenty, and any left over can go direct to motherboard.

I'll be buying new case fans 5xcm 12cm I fancy going from stock coolermaster fans to newer quieter design thinking five of these

noctua d14, so 12cm and 14cm noctura fans on that HSF
unsure of GPU at least 6800XT, will test out my old 480 and see what fps I get.

they have high speed models (so do noctua) but I don't want it too loud

Would be great if they was a high output single method, rather having lots of splitters, just to make cable management and clutter. ...oh they do exist but not cheap!

That branches off onto five. Not sure if PSU cable is molex only or molex and sata mixture if the former that could mean I don't need the extra molex only cable

Just checked it's sata cable only and molex only. S

Might go for one of these, will allow all five case fans to go off one PWM header but molex power.

"
Sleeved PWM Fans Extension Power Splitter Cable,Connector 4 Pin Molex or SATA to 3 4 5 6 Way 4Pin Fans Spliter Power Cord for Motherboard PWM Header
Power from PSU Molex 4-pin or SATA 12V DC, supporting up to 6 PWM fans from a single motherboard header
PWM 4-pin female connect to motherboard for RPM feedback,allowing all fan speed to be synchronized with CPU load
Compatible with 4pin PMW fan connector and 3pin fan connector (Due 3pins no PWM controller, 3pin fans would run in full speed.)
Power from PSU 12V DC only,do not utilize for 5V DC fan
Sleeved in a black is enhanced cable management,enclosure to provide a sleeker look that seamlessly integrates into the case's interior

Note:
Since only one RPM signal can be read by one motherboard connector, only one 4 TIPS CONNECTOR of the fan splitter cable carries an RPM signal. Thus the motherboard will only read the RPM signal of the PWM device that is connected to full 4-pin connector.
The other four male connectors are missing the pins of tachometric signal,ensure your fan speed monitor won't bounce all over the place from getting three sense signals.Guarantee motherboard getting an accurate RPM signal.
Only one of fans sends its tach signal (the one with full 4-pin connector) reports its RPM, but the others will still follow the PWM signal."
