CPU fan speed stuck at 4218rpm

[ipb_uk]

Hi,

The CPU fan seems to be stuck at 4218 & 3515 rpm. Not sure how long it's been like this but at least a week.

Room temp = 23c

CPU = 45

System = 55

Disk1 = 38

Disk2 = 38

Disk3 = 37

Disk4 = 39

Disk5 = 40

Disk6 = 37

Fan setting = Quiet

File search = disabled

Antivirus - enabled

System fan = 958rpm

What firmware are you running - not sure what to make of V6.9.00 2x2TB (4x6TB)

[ipb_uk]

It's on 6.9.2 with 6x6TB disks.

I'd forgotten about my signature as it doesn't show on my PC. Hopefully I've updated it and can bee seen by someone, I can't see it in my posts though.

Of course the sig. shows silly me.....

Sounds like a configuration error.  If you have SSH enabled, please post the contents of ./etc/sensors.d/system.conf.

I ran 6.9.1 and currently run 6.9.2 on my PRO 6 coming from 6.5.0 and I have to say that the fans never worked better than with 6.9.x.

This is not an immediate help to resolve your problem, but I thought I share this.

That's the normal content.  

I think you may have one of the Pro's that has the 3-pin CPU fan connected to the I/O board instead of the 4-pin one connected to the main board.  Another user reported a problem with that configuration.  Did you have to run a special fan patch when you had OS 4.2.x?  If so, then that's it.  Apparently, Netgear forgot about that version somewhere in updating OS6.  It is unsupported, after all.

See this thread for the likely fix: CPU-fan-stuck-on-full-speed-on-upgraded-x86-OS6-pro-business.

It's a shame this forum software lacks a decent search function and you can't easily find such things yourself.  (Hint, Hint to the Netgear powers that be -- this forum software STINKS.)

Before editing the file, you should make a copy (using a name that does not end in .conf) to make it easier to go back.  And if you still have a leftover pro6-fan.conf from an older version, you may need to delete or rename it, too.

The CPU fan is conected to the main board (4 pins). It takes about 20 minutes for the fan to get to full speed.

I don't think I did that patch.

I do have a pro6-fan.conf file.

Contents of that is 

chip "w83627dhg-*"

ignore fan3

With the side panel off the fan does slow down, replacing the side panel and the speed creeps up again.

With the side off, the cpu temp is 38 and the fan speed is 2109. Watching it for a few minutes, the cpu jumps to 45 for a few seconds, but mainly it sits at 36-40 and the fan speed stays between 1917-2109.

I've give the fan lead a wriggle, before replacing the panel. After 3 minutes the cpu is 45-47 (jumping to 51 for a few seconds), and the fan speed stays between 1917-2109.

After 14 minutes it jumped to 53 for a few seconds, this increased the fan to 2636 and stays there and the temp. 48-49.

18 minutes a small jump to 3013 and the back to 2636, temp 45-46.

24 minutes settles at 3013 - 46.

28 minutes - 3515 - 45-46.

30 minutes - 2343 - 44.

32 minutes - 2109 - 44

34 minutes - 1917 - 45

Seems to behaving it self now, so it's back on it's shelf again.

Thanks.
