ReadyNAS RN 104 Automatic FAN-Control

I was fiddling with this too on my RN104. Even when the cpu reaches 70 degrees, the fan runs at 800rpm.
Fancontol works, but i don't know how to get the temparature sensor in the config.
I can see that it is located in /sys/devices/platform/axp-temp.0# cat temp1_input gives the temperature.
Next step is to make it work with lm-sensors or fancontrol, but i am kind a stuck here.

New all time high record. the room where the nas is is about 23 degrees celcius and the ventilation is good.
45degrees for the center drives and 76 degrees for the cpu. This appears to much to me

dishmagic66 - what drives are you using?

I have 4 Seagate ST2000DM001 installed.
The high temperature occurs when moving large amount of data over Gbit lan to the nas and running Transmission at the nas at the same time.
When the nas is idling the cpu temp is about 55 degrees and the drives between 41 and 43 degrees. Again with 23 degrees room temperature.
To me the drive temperatures are not that shocking. but the cpu temp is, When playing with pwmconfig and the fan running at 1500 rpm then the cpu temp sinks below 50 under load and under 38 when idling.
Even when the fan is at 1000rpm during idle, the cpu temp stays around 45 degrees.

I use WDC reds in my RN102. The room temp is similar to yours; the drives run ~35C and the CPU runs ~60C. The fan is ~800 rpm

My guess is that Netgear still has to do some development to do on this matter.

same problem here. I didnt get fancontrol to work, too. It does not only depends on the not detected temp sensor but i am also not able to set the fan speed to a higher value at all. My cpu temp was above 75 degree also.

Support told me that the fan speed spins up > 85 degree. That sounds crazy to me. I did start a support question to the cpu manufacturer marvell regarding valid temperature values. If i get an answer i will let you know...and of course netgear also.

I dont know why this is so hard to change by the user.

NetGear would have decided when to spin up the fan based on extensive testing and information from Marvell etc. on safe temperatures for the hardware.

At least i got someone on the phone. This company is a marvell certified marvell system design company. So they design systems with marvell components. As the system spec is under NDA as i' read somewhere else, i cannot cite officially.
He says: there are at least two different specced socs. And, yes, one is specced for running at 85degree, another for running at 105 degree.

But, in his personal opinion, he says, the netgear design is very 'sporty', means: this is not typical and even if the soc will survive, all surrounded components will be affected, with an outcome of a shorter life time of this system.

Well as well as taking into account the CPU temp, the drive temps would be taken into account too, I think (assuming it is the same as with older models). So if the drives got over a certain temperature but the CPU was still < 85 degrees the fan should speed up anyway and if this still doesn't fix the issue the system should shutdown.
