Re: Twitch brought my PC down :(

  This is not a complaint - I just want to make the facts known.

  Today, when watching the VTC game, I twice experienced a sudden POWER OFF after a few holes played. Can't remember such shutdown ever.

  The first time, my whole PC environment was active, mail, Office, other browser windows, but then I started only the browser with a few windows. Nevertheless, I just missed the putts on 18.

  Yesterday, I watched part of the other game without difficulties, can't say if I stayed on longer.

  System is Win 7 Pro, with OS, FF and Flash freshly updated.

  You could have experienced a thermal shutdown.  It happens when the CPU reaches a certain high temperature.   The system will shut down to save the CPU from burning up.

  It happens to me on Skype while I'm sharing my laptop screen with another person on Skype.  Streaming the game screen pushed my CPU to 100% utilization and after about 5 minutes of that the system said ENOUGH! and shut down.  Putting the laptop on a cool pad helped some. 

  Check your CPU usage using Task Manager the next time you view Twitch.

  Thanks Andyson, this came up to me, too.

  Good or bad, I had my laptop cleaned internally three months ago after some "fan error" issues. A cooling pad is hardly possible though because it sits on a docking station.

  I might perform a test by watching the replays, perhaps.

  andyson:

  You could have experienced a thermal shutdown. 

  Reading the core temps, I agree. It's a Mobile Intel Core i3 390M (Arrandale) from 2011.

  Idling, it shows 55 C, with the game active, around 70 C, but with full screen mode it soon exceeds 80 C. Top value after less than a minute was 85 C before I switched back. The Tj.Max is shown as 90 C (protection limit?)

  I usually don't play on full screen, but I turned it on for the Twitch session. Thus, Twitch is innocent, it's a thermal weakness of my Rechenknecht (computing hand).

  Thanks again for the advice Andyson!

  My laptop turns into a cooker when watching Twitch.

  So def. some problems watching twitch on laptops.

  Bought a cooler/extra fan, I hope that fixes my issues

  90°C is pushing the boundaries.

  The fan on my laptop sounds like a jet engine when I'm on Twitch.. Don't even get me started on trying to stream a game.. I gave up on that before I set fire to my house.

  90°C is pushing the boundaries.

  It is what Intel indicates, being the lower value. I'm only reading that Tj.Max is the threshold to throttle the frequency. The shutdown limit should be 20-25 C higher.

  I'm with you that it should not arrive there so frequently (>80 C every 10 mins), so I should care again for the thermal state of the notebook.

  When the temperature of the cpu starts approaching its upper temperature limit you'll probably experience the shake rattle and roll.  The cpu performance is sporadic and its performance is reduced. 

  The temperature limit is imposed to safeguard not only the cpu but also the cpu fan, etc as well.
