Confusion reading almost illegibly tiny pc fan wire ratings

 Share

I'm going to quote the rating i see on my cpu cooler's 3 way fan splitter as accurately as possible: "300V 20AWG (28AWG?) AWM 1 A SR-PVC 105ºC 20AWG (28AWG?) FT1 -LF-". I was looking at the wire rating and noticed the "1 A" and thought I was screwed because the total amps I need for fans on that splitter is 1.65A, but then I started looking at the wires that power my cpu cooler from a header that can supply up to 3 amps that seem to be exactly the same gauge. Four parallel wires of 28AWG gauge carrying about a max of 1 amp makes sense, but since the wires look like they're the same gauge of wires that can carry more current it seems more likely that they are 20AWG wires which can carry 6 amps total in a group of 4. Is 20AWG the standard gauge for PC fan wiring? Was I misreading the label when I thought it said 28AWG? What does the "1 A" part of the rating even really mean? I really don't want to fry anything.

First of all.
Are you sure you are reading the cable information, not the black heatshrink's ?

it's definitely a black cable, not a heat shrink, 4 individual small black cables grouped together

What cooler that splitter came from ?

Darn i guess it didn't show the picture, it's an arctic liquid freezer ii 420. I also just measured the diameter with my calipers to be about 0.0375" which seems to be in the ballpark of 20AWG gauge

Well, if it's from well known (for their safety) brand, it should be fine, unless there's a factory defect or something. Well if you use the fans they came with atleast anyway. I just checked Arctic's website and they said their fans is only like 0,17A for the RGB ones, so only around 0.51A for 3. Way below even 28awg chassis wiring amperage limit.

If it's some obscure brand that comes from alibaba or something then I will try to check the actual conductor cross section size, since some cheap arse cable only meets the awg standard by insulation size only.

I'll set everything up since i have a feeling it's fine, but not power anything on until i can get on the phone with arctic tomorrow morning just to be sure.

Well, pretty sure GamersNexus would've hounded them already if their cabling isn't up to standard.

If you you plan to use some sort of high power industrial fans though..., probably best to get a better cable.
Probably need to DIY one, since mostly out there are made for standard PC fans.

If I did need to find an alternate way to power the fans it seems like I could plug the main lead of a simple pwm fan repeater powered by a sata cable into the first branch of the 3 way splitter that gets all of its signals from the cooler as if it were a mobo header, i could hook up the 3 x 0.55 A fans I have to the repeater without any issues and it would be throttled directly by my cooler, would that work?

or instead of a repeater, a fan controller that can handle the current i need for each fan
