ARCTIC Case Fan Hub Review: Ten Fans, One Header

This solves an unglamorous problem completely: a case with more four-pin fans than the motherboard has headers. It costs very little, it is genuinely well specified for what it is, and the specification that matters is not the one printed largest.

A note on this assessment: researched from the manufacturer's published specification sheet, not wired into a running build here. See how we test.

The problem it addresses

Motherboards ship with four to six fan headers. Cases increasingly ship with six to ten fan mounts, and adding a radiator adds three more. The arithmetic fails quickly, and the two usual responses both end badly: chaining fans off one header until it exceeds its roughly one-amp rating, or plugging the overflow into a Molex adapter so those fans run flat out forever.

The second one is the more common, and it is why a great many machines are louder than they need to be. A fan at a fixed full speed is a fan with no relationship to temperature at all — the mechanism behind most of why a gaming PC gets loud.

How it is specified

Model

ACFAN00175A

Power

SATA power connector

Control

One 4-pin motherboard fan header

Outputs

10 x 4-pin PWM

Warranty

6 years

Dimensions

86.3 x 55.6 x 14.3 mm

Maximum per port

1 A

Maximum total current

4.5 A

Read the third and fourth lines before the first. Ten ports is the marketing figure; 4.5 A total and 1 A per port is the engineering one, and it is the number that decides whether your particular fans fit.

What it gets right

It draws fan current from the power supply through a SATA connector rather than through the motherboard, which is the whole reason the device exists. The board supplies only the PWM control signal, at a current a header can trivially handle, and ARCTIC publishes both the total and per-port ceilings rather than quoting a bare port count and letting the buyer guess.

Six years of warranty on a passive-ish distribution board is unusual, and 86 x 56 x 14 mm is small enough to hide behind a motherboard tray rather than becoming another object to route cables around.

The functional result is that every fan in the case joins the same temperature curve. That is a noticeable change in a machine whose overflow fans had previously been running at a hundred percent since the day it was built.

Ugly score 6, and it earns it

It is a bare circuit board in a plastic shell with ten sockets on it, and once it is installed it lives face-down behind a metal panel where nobody will see it again. There is no lighting, no anodised shell and no attempt at a shape.

That is the correct design for the job. The competing products in this category are the ones with illuminated edges, sold at three times the price, doing identical current distribution. This is the version that spends its budget on the specification sheet.

Where it stops being the right tool

One curve, for everything

Every fan on the hub receives the same PWM signal, so intake and exhaust behave identically and a radiator cannot be given its own ramp. For most builds this is fine and arguably desirable. For anyone who has spent time tuning separate curves per zone, it is a step backwards, and a second header or a proper multi-channel controller is the answer.

Tachometer feedback all but disappears

Ten fans, one RPM reading. Software fan monitoring will show a single figure and nine gaps, so a seized fan on port seven announces itself by temperature rather than by an alarm. On a machine you open once a year that is a real consideration.

The current ceiling arrives before the port count does

Add the amperage printed on the fan labels. Ten low-speed 120 mm case fans will not trouble 4.5 A. Six high-static-pressure radiator fans might, and exceeding it is not a graceful degradation. The distinction between hubs, splitters and controllers is set out fully in fan hub vs splitter vs controller.

Who should buy it, and who should not

Buy it if a build has outgrown its headers and the overflow fans are currently running at a fixed speed. That is an extremely common situation, this is close to the cheapest correct fix for it, and the audible difference comes from the fans finally slowing down rather than from anything the hub does itself.

Skip it if the board still has free headers, because an independent curve and a working RPM reading per fan is better than a shared one. Skip it too if the fans are three-pin, where voltage control is the only mechanism available.

Would we buy it again?

Yes. It is the sort of component this site exists to point at: unattractive, cheaply made in the sense that matters least, properly specified in the sense that matters most, and a complete answer to its problem. The wider set of quiet fixes is in ugly things that make a PC quieter.
