The ION VAN-400B has two 80mm thermally controlled fans inside it which also can be controlled via a fan controller on the back of the power supply.

In the past, we've found that after a long period of time the fan can stall if kept to the quietest fan speed setting. On the Vantec Stealth 470W PSU, this only became apparent after about 10 months of use. I would recommend keeping the fan speed set to medium, or full.

On the rear of the PSU the ION features the usual power socket, as well as an additional power outlet. To the left sits the 115/230V selector (make sure it is set to the right position before turning on the PSU), and to the right the fan speed controller.

While the ION VAN-400B does not have Serial ATA power connectors pre-wired, Vantec do include two molex to Serial ATA adapters so it can be used with a set of SATA hard drives. Power supplies don't really need to come with a user manuals as they're pretty straightforward to install and use, but Vantec include one regardless.

When we take a closer look at the power supply we see that guts of the the ION VAN-400B are manufactured by Topower.

Once we're inside we can see that the two 80m fans are detachable, that's great news for those of you who have dusty rooms. When the fan dies, you can replace them.
