Temps can reach up to 90-100C before PC crashes.
This is the only program that causes such extreme temperature and CPU strain. I can game for hours with CPU reaching 60C tops. Also this is happening when the launcher is updating BFA pre-patch to my understanding.
When I open the Blizzard launcher, literally 10 seconds laters CPU is at 100% and temperatures rising and have to quickly close it.
Any clues?
Get a better cooling solution because it shouldn’t reach 90-100c even at 100%. At 100% mine reaches high 70s.
I’d rather not replace my fans for one single program that chooses to peg my cpu at 100% for some background download.
Meh, ofc having a cooler that can handle your CPU @ max load for a while would be great, but not always possible, worthy nor needed.
I’ve made a similar topic way back, I find this behaviour weird. It’s using much more resources for an update than any other piece of software I own or have ever owned. But the answer is clear cut: Your own issue.
While the source of the issue is clearly some unoptimised or inefficient piece of software handling the updates.
Actually, I’ve come across systems where the (default/stock) cooler can handle less than the output of a CPU at full load, go figure what happens then :). Question remains, why does WoW need 4 Cores + 4 Threads (in case of a hyper-threading quadcore) all at 100% to run an update?
What Dryni said is pretty correct.
Even at prolonged 100% utilization, your CPU should not get that hot unless your cooling system is working badly.
If you have an aircooler, check that its not caked full of old dirt and dust, and that the fans are spinning correctly.
If you have watercooling, check the fluid levels.
If it reaches 90-100c at 100% then it’s likely running hot even when you’re gaming, shortening the life of the components in the computer by making it run unnecessarily hot.
But when I play games (or do anything for that matter) it sits at 45-60 tops and 30C idle. When I launch bnet app and it starts downloading some update it just melts, does that sound normal?
That’s rather high if it’s reaching 60. Mine is at 37-40c when playing games and doing other stuff at the same time, like now at 30% cpu usage. So, you have a cooling problem, which isn’t really blizzards fault.
There are two issues which, imo, both are valid:
a) CPU should not reach that high temperature even when fully used. If it reaches that temperature it should automatically throttle itself and not crash. Have you overclocked CPU or otherwise changed settings which might interfere on the throttling?
Software developers can’t really do much here if the program needs lots of CPU power and the computer for whatever reason gives it so much that it starts overheating.
b) The Blizzard update agent should not take that much of CPU power when it is prioritized like the other applications. It can adversely effect other programs. I personally have noticed this, too, especially if I am playing some othergame or doing other CPU intensive tasks. Manually setting the process priority to “Low” using the Task Manager has solved that issue. The update program should adjust it’s own priority so it can be still be run when CPU is not otherwise tasked.
As for why Updater uses so much CPU power… My personal guess is that Blizzard is using some heavy compression and maybe even patching files rather than just transfering new versions of the files to save bandwidth on the updates.
Usually if the launcher is using lots of resources it’s file system/hard drive related.
In the past the Blizz launcher used some odd WMI query based stuff to deal with files. If your PC has some kind of issue involving WMI settings this can cause the launcher to get stuck and endlessly use resources.
You could try running lodctr /R from an admin command prompt but make a Restore Point first.
