ReadyNAS Pro: System temp running out of spec

thanks chirpa, my Case is #13105855
I just sent logfiles to Arthur who is handling the case and updated the ticket with a very long explanation i won't post here since it;s a book heh.

hope i can help with pinpointing the issue

@mule:
If it's certain batches i must be the most unlucky person in the world. I have 3 Pro's (apr 2009 from newegg in the USA, jun 2009 from a dealer in Holland Europe, and another aug 28 from newegg in the USA) and all 3 have the exact same issue :P
They also have another weird issue with reading speeds which also happened after i upgraded to 4.2.13 on each of them.

Lets hope they figure out what it is soon :P

Ok, speculationg from my side ends now. I'll wait and sit down until netgear comes out with infos and hopefully a solution (soon).

Case # 13151284

An update.

It has now been 3 weeks since my TEMP 1 sensor problems.

Ambient temperatures are now within the 20C-27C range in my house and as a result the PRO is no longer exhibiting such problems. The problems for me started
when ambient temperatures were within the 31C-36C range and humidity at 85%.

The problem seems to be related to 4.2.13 as I never had problems before this version.

Latest readings (20C-30C, humidity at 50%)

For me it's totally indepent of the ambient temperature and it happened with 4.2.12 too.

small update from me to.
After installing a cooler master fan it was great for 2 days, rpm were 1900 for my case fan, stayed at a nice 55-57c.
Then suddenly at 22:06pm and at 79f in the house with AC on it started overheating to 66c :P
After about a minute it sped up and now were down to 57 again..i wasn't even using it most of the nite.
Then about 8 min later same thing, over heat, speed up, cool down.
When it started going back up i hit recalibrate fan and its been good for a day again... so weird

Started getting warnings in the past 24 hours for Temp 1 going over threshold. I'm running 4.2.13 final on a Pro Biz. The sys fan runs <1000 RPM most of the time and no amount of recalibration helps other than to verify the fan goes up in RPM and then settles to 900 or so. I was beginning to think this was normal until someone on Twitter pointed out this thread. There was a fair amount of dust in the unit that I blew out and that helped slightly but Temp 1 still overs around 62C. I powered up my spare Pro Biz with 4.2.13 and it too shows the sys fan running < 1000 RPM (was 1800 for a few minutes after powering it up) and Temp 1 is close to the threshold.

Oddly enough, while typing this, my primary Pro Biz sys fan stepped up to 1550 RPM and Temp 1 is 56C. No clue what triggered it to increase RPM other than perhaps seeing the 2nd was on (linked to the other to provide UPS info). I turned the 2nd off but the fan has stayed steady at 1577RPM for the last 10 minutes.

(Edit: Turned off the 2nd Pro Biz, 1st sys fan dropped to <1K RPM within minutes. But turned on 2nd again and I think it was coincidence. Both are reporting sys fan RPM < 1K and Temp1 @ 64 and 65C. Reverting to 4.2.11 if I have it.)

(Edit #2: While downloading 4.2.11, noticed BOTH of my Pro Biz were running >1700RPM on the sys fan and dropping to 56C. Ok. I'll have to play with this some more.)

i'm just chiming in on this, i don't have a case open yet, but i've seen the same behavior with my Pro, i'm pretty sure since 4.12. my cpu fan is running at 2000 RPM, and the main at 1000. my main temp hovers at about 141 pretty much all the time, and can easily spike into alerts depending on conditions. i'm running a pro with 4.2.12 final with only 4 1tb samsung HJ's.

i'd be happy to replace the fan with something, perhaps different resistors to get RPM's- if only Netgear would chime in. this threads been going for months, mostly ignored.

Yeah, it does seem to be going ignored. My issue keeps popping up....
