WD EX2 is a great NAS device, but unfortunately the cooling system does not work correctly
The Motherboard and the Disks are always hot even when it’s in Sleep mode, under a normal usage the tempreture will increase and the cooling fan never works at all. We are always worry about our data because of hotness of the disks and the unit.
This problem has been said repeatedly from the users in this topic but there were not any result except turning on/off the fan manually and this is not a solution.
There is another major problem in Sleep mode, when the disks are not in use it begins to work and the whole unit wakes on, it might be because of an arp request. But it would be better to keep the disks silent when there is no request for the data’s stored on the hard disks, even for SSH access all the unit begins to work
I want to ask WD developing and programming team to improve the cooling system and fan function and optimize the Sleep time for disk access in the next firmware’s
