FAN problem after upgrade from 4.2.28 to 6.5.0 T338
Hi All. My first post but been reading from many days.
Recently i bought my Netgear NAS, that is RNDP6310-200 which is (by all signs) PRO6 v2, running 6xWD 2TB disks.
On 4.2.28 temps were - CPU 35-38 'C , System 45-55 'C (depending on situation, but what is more important, the fans work was smooth (gradual increasing/decreasing the speed, no sudden stops/starts).
I upgraded to 6.5.0 T338 using this link: readynas dot com/contributed/mdgm/r4tor6/ and following this thread: https://community.netgear.com/t5/Using-your-ReadyNAS/OS6-now-works-on-x86-Legacy-WARNING-NO-NTGR-SUPPORT/td-p/897021
I intended to upgrade to 6.3.5 as I found on forum this is the best one to start upgrade process with, but supricingly all files stored on above link were identical (6.5.0) despite the different names.
Everything went ok, system is alive and much faster than on old software.
So now it is stock PRO6v2 (1 gig ram and Intel e5300) with OS6.5.0.
But:
CPU temp seems to be similar to what was before, but system temp is way higher - over 60 'C while iddle (at least this is what reading on frontpage says). The fan became yo-yo - changing speed from about 400 to 2000 and back every minute or so... So it is like quiet, noice, quiet noice and it lasts all the time.
Also, I'm being flooded with system emails saying "Fan System in enclosure Internal speed is below threshold. (xxx rpm)." - where xxx stands for any number from 400 to 500 range
There is a lot of threats regarding similar problems, but the solution is inconclusive and after few days, I still have concerns and lact of knowledge what to do to sole my issue.
Any help would be great.
OK, I see what's going on. Thanks for the logs. Strangely, your fan speed is drifting lower, without us ever adjusting it. It appears to be correlated with disk spindown, but I really don't know why that would have an effect. Anyway, we'll have a change in RC2 that should knock this out once and for all.

Have you tried changing the fan mode to the cool setting?
Hi, and thank you for the answer.
Yes, in fact I did. I went through all 3 modes:
quiet - makes yo-yo of the syetem fan and emails are sent every 20 minutes or so
balanced - I'd say less yo-yo, more tornado (comparing to the quiet mode), plus emails
cool - sounds like 5th class tornado - but not much drop in temperature reading (which is obvieusly false high), but no emails
This is all about system fan and temp reading.
CPU fan/reading seems to be fine and realiable.
It is probably worth to note, that emails are regarding fan speed being too low, not regarding temp.
Please send me your logs (see the Sending Logs link in my sig).
