Service Action to Prevent PSU Failures in ReadyNAS NV/NV+
A Service Action notice has been posted in the Announcement forum to prevent ReadyNAS NV and NV+ systems from premature power supply failures at viewtopic.php?t=10259. If you own a NV or NV+ within t...
Hi Yoh-dah,
Thank you to you and the Infrant team (Jedi council) for bringing this issue and the resolution options to our attention.
I too have concerns about reversing the fan and the subsequent dust flow change gumming up the works. I was far more concerned when I read that some users who used the fan reversal technique encountered temperature increases in their hard drives.
The issue I wanted to raise in this post is the choice of the 2 fan speed modification patches. I understand that the Enhance_NV_Thermal_Characteristics engineering patch will simply set the fan speed minimun to a fixed 2100 RPM. The EnableFanMinRPMOverride addon on the other hand will allow me to set any speed as the lowest fan speed limit. I have always wanted to use the override addon so that I could increase the fan speed on warmer days when I wanted to bring the drive temperature down a little. I have never loaded the addon given the dire warning and implications on the warranty.
Would it be possible to combine the two addons and ammend the EnableFanMinRPMOverride addon to have a system defined minimum fan speed setting such that this addon can no longer be tagged as warranty threatening. The UI could then allow users to select any fan speed they want as a minimum but if it is lower than that defined as safe by Infrant then the minimum will be reset to the minimum safe level. The minimum safe level can be defined by Infrant and set as appropriate for the ReadyNAS model, engineering revision, serial number, etc. Obviously anyone who wants to increase the speed a little can then safely do so.
The benefit of this defensive coding would be that anyone who has access to FrontView who may try to set the fan speed lower than is safe will not have their change accepted and the ReadyNAS will not be put at risk.
For those who *really* want to set the fan speeds lower than recommended another addon can be provided that overrides the safety limit. This addon should be the one that carries the warranty threat etc. This proposed new addon would return the EnableFanMinRPMOverride addon to its current, and potentially dangerous, configuration.
What do the Jedi council think?
