ReadyNAS RN 104 Automatic FAN-Control
Hi All, I have a Big Problem with my New (2 Weeks old) ReadyNAS 104. When i have a look at the WEB-UI under the Performance TAB i see the FAN is always running at only ~875 rpm. After a fresh st...
My RN104 is telling me FAN : 787 RPM, CPU : 53°c, HDD1 : 37°c, HDD2 : 41°c, HDD3 : 40°c, HDD4 : 37°c. He is sitting idle right now (not home) but I've never seen it going over 78°C.
I believe disks are quite tolerant to high temperature. I think I remember a google study saying that anything below 45°c is optimal to avoid disk failure, so 44°c is still good ;) and even if it goes to 47-48 I don't think this will really matter. As for the SoC, I believe marvell took some margin when releasing the spec. I don't think we really risk anything with this (Netgear has a 3 year warranty on the hardware for the RN104 I recall). I believe if they were having any doubt they would have set the threshold 5°c lower and bump the fan speed by 50-100RPM just to be safe.
