Can this fan controller handle my fans?

ApolloFury · June 1, 2019

I am looking at the Deepcool FH-10 which is a fan hub for 10 fans powered by SATA.

While it advertises that it can handle 10 fans, can it handle power hungry ones though?

For instance, I have 5x Fractal Design Venturi HP-14 (0.2A each) and 5x Noctua A14 3000RPM (0.55A each). The Fractal Design fans are not an issue but the Noctua ones might be too much?

I think it should be fine because a single SATA power cable can handle up to 4.5A...but I am not sure how power supply works. For reference I have the CoolerMaster Vanguard 1000W.

Thanks.

You should have no problems with that setup. You'll only draw 3.75 A which gives you a safety margin to SATA's 4.5 A max if you run all fans at 100 percent. That 4.5 A is for the whole SATA power interface, so cables and power supply are all included in that rating.

Running them slower will reduce the power draw.

Just to clarify. Is the 4.5A max limit total is for all my SATA devices or the 4.5A limit for that particular chain/cable only?

For instance my other SATA-powered devices are the 2x 2.5" Samsung SSDs which are connected via separate SATA cables (not daisy chained, two separate cables)

So if I use this fan controller, I would now have three SATA devices (i.e three SATA cables) plugged to the PSU.

Thanks.

The rating is for each individual SATA connection at the power supply, so each chain should have no more that 4.5 A between all devices plugged into that same cable.
