Fan PXI

• Automatic shutdown of the PXI-1033 chassis. Noisy case fan.

  I went to use my PXI chassis today. I always keep power, but today it wasn't on when I went to for use. It turns out that there is an auto power down if the fan "fails". So, I removed the power to frame and then repowered the chassis. Heard a loud fan - as one of the blades reached something solid. And I only heard something when the chassis in the sense of 'big fan down' is the big fan on the "merits" of the unit which cools the boards. To resolve this problem, I removed the air filter and then the wire screen and then wire fan guard. I rebent the 4 feet of the wire fan Guard (be sure to rebend both elbows on each leg) so that it is wider the fan blades. Put back to gether and now no sound.

  Apparently my PXI chassis is part of a reminder "replacing the fan.

• PXI-1044

  I am currently working with the NI PXI-1044 chassis. Whenever I turn on I meet a solid red light and fans to remain in high mode.  I looked in the manual and all she's talking to a flashing red light. I wonder if this can be fixed with a simple exchange of a new part and not a swap of all of the module.

  Thank you

  s.jimenez,

  Thanks for the quick response. I actually found the question. Apperantly that fans have been changed earlier due a fanand sqwaky replaced with a type that is not compatible. It turns out that the fans who were in it were a wire (pos, neg, and lock the rotor sensor). The fans who had to be installed should have been a wire (pos, neg tacho sensor).

  Your response was on the spot. Thank you for your help.

• PXI-1042 - switch LED green flashing when the chassis is disabled

  When the PXI-1042 chassis is off, the green signal LED power switch (I use the word "flicker" because the LED flashes irregularly and without full intensity) and the cooling fans will be starts randomly (sometimes one at a time, sometimes both).  When the chassis is on and in use, there is no significant difference in normal operation.  I understand that a flashing green light indicates 'air intake temperature exceeded the operating range chassis' (by Manuel PXI-1042).  I don't think that's the problem, because the chassis works very well when you use it.

  Everyone knows about this problem?  Is this a problem?

  Thank you!

  My biggest concern would be there that it will not warn you when you are outside the temperature range. However, since it does not work correctly when the chassis is turned on, I don't think that there is a problem. Of course, there is no way to know for sure without sending the camera for RMA, but my best guess is that you'll be fine.

  Hello Jainsch,

  just a little addition:

  Please set the speed of the fan in the back to 'HIGH' and insert a Slot-blocker in all empty slots to improve airflow (cooling).

• problem of fan with sierra?

  Hello

  Everyone knows their MacBook Pro fans go into overdrive without provocation since the upgrade to Sierra?

  I don't have that mail and Safari open (to make this post) and fans are whirring away as I use a 3D graphics heavy program.

  The room is cool and the MacBook is raised on blocks to facilitate the movement of air, but its always acting like there is more of the work in progress.

  It doesn't seem fair.

• iMac 27 "mid-2011 - Intermittent problem with CPU fan running at full speed and sleep mode.

  Hello!

  My iMac 27 "has an intermittent problem with the CPU fan runs at full speed. Sometimes it happens at the time when I start it, sometimes only in my session, and sometimes only after a certain time. So does seem to be a problem of "heating".

  Second issue is with the mode 'sleep'. It may occur also at any time, at the start of the iMac, session, or after a certain time. But once he starts to go in mode 'sleep', when I wake up, it goes right back in mode after a few seconds and that it will continue indefinitely until I restart the computer.

  What could be?

  Please help me!

• App, networking, process cloud runaways; Very slow to connect to servers, high fan

  I have the same problem on two different computers. A new installation (of Sierra of MacOS) (with costs users, no restored settings, preferences, etc.) fixed, but not the other. (Past the wire: all Web apps suddenly slow; fan high speed).

  On the computer that still does not, have the following processes often rampant and prevents the computer access to the servers to load pages, apps, etc..

  • trustd
  • Mail
  • messaging networks
  • Safari
  • Networking of Safari
  • storeaccountd
  • AKD
  • accountsd
  • nsurlstoraged
  • nsurlsessiond
  • syncdefsultsd
  • cloudd
  • com.apple.CommerceKit.transactionservice

  Obviously the issue transcends the user the user and settings (because it affects the settings and new users).

  So I guess that it is a problem with iCloud? A question of trousseau (iCloud)? How to fix this?

  I am VERY interested in any orientation.

  I just tried these steps recommended for new users of macOS with wifi problems: http://osxdaily.com/2016/09/22/fix-wi-fi-problems-macos-sierra/

  The problem persists.

• The operation of the fan of excessive causing Sierra

  After the installation of Sierra 10.12 the fan on one of my MacBook pro is running excessively. Activity monitor shows a process 'DCs' as a means of 93% of the CPU.  Tried to use force quit and it comes right off.  On my other MacBook, the activity monitor shows the 'DCs' as 0% CPU and there is no problem of fan.

  This process is linked to the keychain.  You have the ring of the value be synchronized via iCloud in the system/iCloud preferences window? If so, uncheck, restart and check the DCs again process in activity monitor.

  If the activity has returned to zero, activate it again (if you want to sync on devices) and check again the activity monitor.

  

• Fan MacBook Air updated according to Sierra

  Given that I have improved my old MacBook Air from two years to Sierra this weekend, it is now heats and the fan turns after a few hours of work. He almost never did this before the update. Any ideas?

• The fan runs all the time because xinetd running more than 80% all the time.  Someone else has the same problem?

  xinetd is running at 83% or more 24 x 7 devours battery in 2 hours or less and making the fan run all the time.  I am connected to a bug report, and it turns out that it was a duplicate because someone else had the same problem.  However, I have no access to the other bug report or find anything either in the discussion forums or online.  Anyone experience this problem?

  Hello gorgonzola1111,

  I doubt that someone else has this problem because xinetd does not part of macOS. Have you installed it from a package of "ports" 3rd party?

• Fans of fast and slow mail after upgrade of Sierra

  So I too just upgraded to Sierra, and I have two problems.  The first I noticed almost immediately after a reboot is something is causing fans to run almost non-stop.  I looked at the level of the console and I see that several root applications use more than 100% of the time CPU.  What the hell is happening here?

  Second, Mail has now slowed down to the point that it is almost unusable.  I click on an email and it will literally be anywhere from 15 to 20 seconds for the mail to open.  Not a complex HTML with email of old thing plain video simple.  What the hell is happening here?  It's maddening.

• The fan works like a crazy and super fast drain battery after installation of Sierra

  I installed Sierra on my MacBook Pro, the fan works like crazy and the battery is empty after about 1.5 hours. Which never happened before. I'm only using Safari and Mail in the moment. I talked to Apple Support and they suggested to reset the SMC, but this brought no improvements. What can I do else? Again, I plan to install the El captain...

  I had this problem just after I installed Sierra on my MacBook Air.  First I tried to reset the SMC and the LANDAU.  This does not prevent fans constantly in the course of execution.  I then used the activity monitor to see what was possibly strain my system.  I noticed the "DCs" process was always sucking up to more than 90% of my CPU usage.  However, others said that it is normal after an upgrade of the OS and it should fall back down once the computer finishes its initial picture and analysis of the files.  So I run my MBA plugged nonstop for 36 hours in a row and the fans just kept running so that the process of "DCs" continued to drain at > 90% of CPU usage.  I also looked carefully at the activity monitor and saw that tasks such as analysis of photos had their own separate process "DCs".  So I dug further into what the devil "DCs" was really do with a lot of CPU resources.  Long story short, I found that there is some glitch in Sierra which causes the macOS stuck on a process involving the keychain and iCloud.

  That's what I did to fix this keychain/iCloud which led to "DCs" fans of triggering and overloading the CPU to be always on:

  -In the activity monitor, I used Force Quit to kill the process that involved the keychain

  -In the activity monitor, I then Force Quit the process that involved icloud

  -In activity monitor, I finally Force closed the process "DCs". (I found that I could not simply force quit 'DCs' without first allowing the keychain & iCloud first)

  -After all, I restarted the computer and fans were finally off the coast!  I open the activity monitor and saw that 'DCs' has is no longer hogging up the CPU usage.  Photoanalysis process were still running in the background at 40-50% CPU use with no trigger unwanted system fans.  the iCloud synchronization and my keychain also worked very well.

  I'm finally able to use Sierra without my fans blazing out of control.  It took me a while to get this sorted out.  Hope this helps to save you a few headaches and time until Apple can get counts that there is this Sierra software glitch they need to address.

• Fan works like crazy and the battery drains quickly after the installation of Sierra on MacBook Pro

  I installed Sierra and since my MacBook fan runs like crazy and the battery drains very quickly. Right now I use Safari and Mail. He has never done this before. How can I stop this from happening? It is now more than 48 hours since I installed Sierra. All constructive suggestions are welcome.

• Fan runs almost always since the installation of Sierra and MacBook Air running Mac OS.

  Hello

  Since upgrading to Mac OS Sierra last night on my MacBook Air (2013, i7, 8gbRAM), fans work almost always, even when I use Safari.  Previously, the fans would go only when I was playing a game, or video edition.  The basis of my Macbook Air is also much more hot he was under El Capitan - once again, just when you use Safari.  As a result, my battery life is horrible - dropped from 100% to 23% in a little over an hour.  Once again, under El Capitan, if I was just using internet, use of an hour would see the maximum of 10 to 15% of decline in battery.

  I turned off my Macbook Air and it turned on again after fifteen minutes, but in 10-15 minutes, fans revived upward and the base (and the top of the keyboard) heated again.  No uncomfortable levels, but certainly noticeable levels.

  Just to remind - I use Safari only when this happens.  Moreover, since the beginning of this question five minutes ago, the % of battery has dropped from 29 percent to 22 percent and the fans are still whirring like the dickens.

  No idea why this is happening?

  Hello, take a look at this maybe of http://www.macworld.co.uk/feature/mac/fix-overheating-macbook-3592266/ article it will help.
