Powering case fans at full RPM - Splitter or no splitter?

[garetjax]

Quick question for you cooling guru's out there. I am currently using a Silverstone FT02 with three 180mm AP181 fans and a Corsair H70 in a push/pull configuration.

In an effort to reduce cable clutter, I was thinking about picking up a Sunbeam Multi-Fan Power Port (MFPP) to power all my 3-pin fans. This device is powered by one, 4-pin molex connector and provides power for up to 6 fans.

My question is will my fans run at a lower RPM using the MFPP because one molex is servicing six fans? Or would I be better served connecting each fan to individual 4-pin molexes so that each fan is being 100% powered and will run at full RPM?

I'm concerned that the Sunbeam MFPP, because it is powering six fans, that the fans will not run at full RPM because the single molex connector that is providing power to the device is being split six ways.

Thanks for the help!

They should run at full speed.

I'm not sure what the maximum power a 4-pin molex can deliver, but I'm very certain it's much more power than you'll need to power just 6 case fans.

Yep, in the past 4pin molex was used in early 'high' power GPUs. I think 6 fans will be just fine 😉

Excellent news! Thanks all! =)

completely dependant on the fan.

lol...

if its a nidec 4300rpm fan, those can draw up to 53W alone.
Add 6 of them, and you got more wattage then a 580GTX. 😀

if there normal fans.. and not specality fans... yeah.. i see no problem running that many on a molex.

I got a good laugh at opening up some of my AP-29 fans and seeing 4 pin connectors. 😵

Way too much noise for where it was located, but they would be great to run in a closet of sound proofing. 😀

I assume though that we are talking about fans that normal users will put into a computer. So daisy chain away or however you plan to hook them up.

I'm curious what kind of wattage that power port can handle. I know most run of the mill fans shouldn't be an issue but I'd like to know what the max wattage per port of that thing or if it's just a strait pass through.
