Computer Fans, voltage etc.

Hello everyone,

I just bought parts for a new PC.

I decided to go for the Asus A620-M, with the NZXT H5 FLOW case.

My question is, I only have 2 fan headers, but I want 4 fans in my PC. Can I use a 3-1 fan splitter?

The case comes with two nxzt 120 f120q fans, and i want to add two be quiet Pure Wings 3 140mm PWM.

Will the power consumption be too high?

I'd probably use two 2 to 1 headers instead, just for better fan curve control.

Assuming you do use a 3 to 1 splitter, it should be fine, the Pure Wings 3 have a max current rating of 0.3A and the F120Q have a max current rating of 0.18A. You want any combination of those three to stay below 1A for the health of the fan header, and there's no combination of three of those that will be over an amp. 2 2:1 headers would also be safe.

Ahh okay, where do you find the information about max current rating? i may be stupid, but i can't find it anywhere

The easiest way is to just look on the fan itself, it'll be printed on the label. If you need to google it though, there will be an online spec sheet for the fan usually on the product page where it will list the maximum current draw.
