Fan Splitter Query (Gelid CA-PWM-03)

pete_agreatguy · 23 Dec 2018 at 19:34

Hi all,

Quick query:

Using a mATX motherboard that only has 1 chassis fan header but need to connect 3x chassis fans to this header.

Going to use the Gelid solution (PWM 1-TO-4 SPLITTER - CA-PWM-03).

The fans use only 0.2 amps. The motherboard header supports 1 amp in total.

Can I just connect all 3 fans via the fan connectors and not bother with the molex power connector?

Or do I actually have to connect the molex power connector?

Just I'd rather not have all 3 fans running at full speed all the time.

Thanks

That's what I thought.

Thank you

Hi guys,

I got directly in touch with Gelid to clarify this. Included my initial message and their reply below:

Dear Sir / Madam,

I would like some clarification on how this product works.

Using a mATX motherboard (Asus Prime B350M-K) that only has 1 chassis fan header but I need to connect 3x chassis fans to this header. The fans use only 0.2 amps. The motherboard header supports 1 amp in total. Can I just connect all 3 fans via the fan connectors and not bother with the molex power connector? Or do I actually have to connect the molex power connector? Just I'd rather not have all 3 fans running at full speed all the time if they can be all controlled by PWM.

Thank you for clarification.
Kind Regards,

Yes you can attached all three fans, they will spin at the same speed, if connected to a PWM header, otherwise they will all spin at full speed

Did they actually answer your question?

Anyway correct information is already provided above.

I would say yes. Why do you think they haven't?

Good point. ~~I'm under the impression I do not need to connect the molex cable; just the 3 fans and the PWM fan header to the motherboard.~~

You do need to connect the molex cable. My apologies; I missed what was meant by tach and pwm wires above. The power is directly drawn from the PSU as stated on the web site which freddie highlighted above.
