Power

Power consumption isn't the strongest point of the NASync iDX6011 Pro, but it's worth keeping in mind that it was also tested with two additional drives compared to any recent NAS that we've tested here at TPU. With the drives sleeping and the NAS at idle, we're looking at pretty much identical power usage as the TerraMaster F4-424 Max, with a 55 W TDP Intel Core i5-1235U CPU vs. a 115 W TDP Core Ultra 7 Processor 255H. With the drives spinning, we also saw a similar increase in power usage, even though the iDX6011 Pro seems to use a smidgen more power here, but this is not due to the Seagate drives being more power hungry. However, once you start using the mechanical drives, power consumption jumps up by around 20 W, which is a bit more than we expected, as the F4-424 Max only jumped up by around 12 W with four drives. At full tilt, we almost hit 86 W, and we did see peaks at over 100 W, but they were rare. Keep in mind that the power usage will depend on the drives and other hardware you add to the iDX6011 Pro, but it's unlikely that you will be able to max out the 300 W PSU.

Noise

The cooling system of the NASync iDX6011 Pro is quite impressive, as at no time during our testing did we notice the CPU fans spinning up to an audible level over the noise floor in the room. It obviously wasn't the only device in the room, but even so, at no point did the fans make noise that was intrusive. In fact, the hard drives made more racket than the fans during normal use, something to keep in mind when you select hard drives, as we only used six 5,400 rpm drives, 7,200 rpm drives are likely to produce even more noise. Yes, it's louder than the TerraMaster F4-424 Max by about 1-2 dB(A) in lighter usage scenarios, but as the fans don't really speed up even under heavier loads, it ended up being a lot quieter when some heavy disk activity kicked in. During normal usage, the CPU blower fans spin at around 740-750 rpm, with the case fans either idling at zero or barely spinning at around 278 rpm, according to Ugreen's Task Manager. Kick the fans into full speed mode and the CPU blower fans hit over 3900 rpm, with the two 120 mm units topping out at just over 2000 rpm, which is a very loud 61.1 dB(A). At no point during our testing did the fans kick into full speed mode.

Temperature

As mentioned several times in this review, the iDX6011 Pro has a very competent cooling system and with four copper heatpipes and a rather large heatsink, there's no surprise that the CPU idled at around 34 °C in a room with an ambient temperature of around 22 °C. During heavy write operations to both the hard drives and the SSDs, the CPU was sitting at around 44 °C, albeit this was only at a five percent CPU utilization. Running some more CPU intensive things would bring the CPU temperatures over 50 °C, but running something like the 7-zip command line benchmark with 100 percent CPU load brought the CPU temperature up towards 70 °C before the blower fans spun up to around 1700 rpm to quickly cool the CPU back down to around 50 °C. The blower fans got audible at over 1500 rpm, something worth noting if you're planning to run a lot of CPU heavy tasks on the NASync iDX6011 Pro.


When it comes to the storage drives, you can see that they ran quite cool during normal operation and even during heavy load, the hard drives never exceeded 40 °C. The NVMe SSDs got hotter, but it was hard to push them past 45 °C with any kind of file copy tests, but we expect them to run a fair bit hotter if you run a lot of drive intensive things, for example databases that belong to some kind of Docker app. Regardless, drive cooling isn't going to be a big concern here, at least as long as you install the included SSD heatsinks, if your SSD doesn't already have one.
