Got something to discuss?

What do you sell that enables me to power this from my 1200w HP PSU, or can it be powered thru an unused molex fault protection port on the X11, for example?

you can use this 6-pin to molex female cable to power up the fan up with the HP 1200w power supply and our breakout board.

How can i control the fan speed by shorting the rpm pins or what ?

Does this support 3 pin fans as well?

1 year 9 months ago

Depending on the connector of your fan. In the end, all you need is 12volt and a ground

How many amps does each fan header support and what’s the max amperage draw on these hubs? I’m looking to connect 6x 1.6Amp fans.

The problem is the cable delivery of the 4pin Molex on this hub. The hub itself can handle it but the wire size is very low. If you feel it’s getting warm than it too much.

What is the wire gauge of the 12v + GND for the molex connector? I’d like to know if that wire is capable of handling 5x Parallel Miner 6100 RPM fans.

It’s not! It going to melt. This cable is very small and will not handle it. Sorry. If you wish to return the item let us know.

    What is the wattage rating of all of components included? I have purchased but want to ensure that the high pressure fans I am using don’t short out the wires.

    • Joseph g (store manager)

      Very low. The problem is the wire size connecting to the Molex power on your PSU, They are too small. I would not push it more then 50watt
