[SOLVED] Is 6-pin PCI-e to Dual Molex for case fans safe?

[lawlessstl]

Hey, I’m in need of some help regarding powering some case fans. I’m planning on powering two fans (120mm coolermaster sickleflow) via molex. My PSU is a Corsair TX550m, and i believe it came with the cable, the “peripheral cable”, that i must have tossed. Anyways, I just picked up a dual 4-pin to 6-pin PCI-e cable and plan on routing it as such: psu>6p>4p x2>case fans (each one plugged into its own 4p).

My two main questions:

1. Is this even a safe means of powering them? It seems like overkill; is that dangerous?
2. Am i supposed to plug each fan into its own 4p male connector? They don’t have the same cabling; one has 2 yellows and the other has 2 blacks?

Great, thank you!

Without a doubt yes, they are safe. Those 6 pin pcie connectors are designed up to 75w each. If you have two fans that consume 75w, you have bigger issues.

Btw bignastid is correct. Unless you get a specialty larger fan the 4 pin molex isnt what you need. You need a sata to 4 pin fan header. They will run at full speed. I recommend larger fans only or it will be noisy at full speed.
