Should I connect case fans to PSU or motherboard?
Depends. If they’re smaller fans connect them to the fan headers on the Mobo. If they’re large fans, like 200mm, definitely connect them directly to the PSU via molex connectors. I’f you install a fan speed/temperature control system, you should connect them to that which in turn connects to the PSU’s Molex line(s).
Do case fans go into SYS fan?
FOR SURE you do not connect a case fan to the CPU_FAN port – that is for the CPU fan only. You may have a port labeled PWR_FAN, and it is intended for connecting a special lead set form the PSU so that the BIOS gets a speed signal from the internal PSU fan and can check it.
Can I use a splitter for case fans?
You will be safe using a fan splitter as long as you the fans you are connecting does not draw more current than the motherboard header provides.
Can I control fans connected to PSU?
Any fans connected to your PC’s motherboard are controllable according to temperature, but those connected directly to the PC’s power supply may run only at once fixed speed. For fans with smaller three- or four-pin connectors which attach to the motherboard, these can be controlled by software, or in the BIOS.
What’s the difference between a CPU fan and a case fan?
Splendid. Well… the CPU fan is for the fan on the CPU, while the chassis fan is for fans on the case (aka chassis). All right, enough with being a smartass. Chassis fans are typically ‘dumb’ fans which spin at a specific speed.
Does using a fan splitter reduce speed?
splitter do not reduce power it only split between the 2 fan and they receive ful power but it will only read one speed sensor for one fan .
Are fan splitters a good idea?
They’re safe. The reason why the fan connects to the motherboard is so that the motherboard can tell the fan when to ramp up its speed (they don’t run at full blast unless they need to).
Why is my PSU fan so loud?
A clogged PSU air intake can cause the fan to run faster and noisier. Clean the PSU fan filter/intake periodically to avoid this problem. Failure to do so will contribute to heat buildup and consequently increased fan noise.
