Power to fans?

[V4oLDbOY]

I got a fan controller off a user on here.

I also have 2 extension cables. One is a 3pin to 3pin. The other is a Y cable. to female-->2 male 3 pin.

Realistically should the fan controller be able to power both fans from one 3 pin port?

I was thinking of having power the two top fans I have in my case at the same time.

Any tricks to tell how fast the fans are spinning? listen, look?

Could the controller potentially power 5 total fans at full speed or is that too much?

EDIT: I dont have my ram or HDD yet so the PSU wouldn't turn on. I used the paperclip + green and blue wires to start the PSU. The fans I hooked up to the Y connector seemed to spin quite fast and were pretty loud so I am assuming they were at top speed, would suck if they got even louder. But it works fine. Might get another Y connector so I can have 2 knobs control 2 fans each.

The description says "20W" with 4 channels, which is therefore 5W per channel (20W per channel is not likely, hehe edit: but not impossible. I can't tell from the product description). Fans vary with their power consumption but if you have five 1W fans then you could then connect 5 fans to a single channel before running into problems.

The label on your fans should indicate either the max power consumption or the max current draw. If you multiply current draw by 12V you'll get power. Most fans use less than 12W, but high-speed fans are likely to use more (this delta uses 30W!)

aha! thats why I ask questions. Thanks that clears that up for me.

mine are 4.2W each fan. Might need to buy another extension cable and hook the fan on the Y to port 3 or 4 on the controller.

but he case fan that came with my CM 690 II says its only 1.8 and the front is 1.92. I guess i can put those on the same Y connector if the CM website is correct or I have the right model.

Yeah I was thinking 1W per fan is typical but really 1A per fan is typical ie 12W. If your case fans only say ~2W then you can definitely put those fans on the same Y connector.
