Aspire V 15 throttles CPU instead of cooling

Hello,

 

I've bought an Acer Aspire V 15 VN7-591G-757V for 1200€ two months ago. This laptop didn't start it's fans if under load, a factory reset didn't help. The Acer support concluded it's a mainboard issue and told me to exchange it, which I did. Having received the new Laptop, I Installed skyrim and it ran as smooth as it should. Two months later, me happily playing on my virtual piano, the sound stops. And again. And again.. Turns out, instead of cooling down the CPU, the CPU decides to stop calculating for a moment untill i'ts 60 degrees again. This causes my Virtal Studio (Cubase 8) and Instruments to freeze for two seconds every 10 seconds, which is unbearable.

I haven't changed anything before it happened. Energy options are all set to active cooling and maximum cpu usage. 

 

I would appreciate if the acer team would publish the Acer "cool boost" for all black edition laptops, so I could manually control my fan, solving the problem. The thing is, the fan isn't broken. For some reason, it just works arbitrarily. It won't start for Cubase nor Skyrim, but by running an acer care center update it magically starts rotating. 

 

Also: Starting a game, i.e. Skyrim, it will run smooth for a minute then become gradually slower untill the laptop shuts down or i close it and find the cpu running on 90°. Further, even when I have just started the laptop and it's on 30° it won't use the full cpu. Starting the program you see in the the picture used to take 5 seconds, now it takes thrice that long, even though the CPU is cool. 

 

I would really appreaciate some input.

    Okay, an update for everyone having the same problem:

     

    I've read dozens of forum entries now and found the most unintuitive solution you could imagine:

     

    Unplug your external Monitor when you boot your PC. 

     

    For some reason, booting the laptop with an external monitor plugged in causes the CPU and CPU fans to boot wrongly. 

     

    That's also the reason this is such a rare occurance, since most poeple don't use external monitors.

    Zounge,

     

    Sorry to hear that you are not having the best possible experience with this notebook, I would like to suggest you go to our Ideas section and post your thoughts about putting Acer Coolboost on all Black Edition Nitros.

    Thank you for this! I bought Nitro VN7-591G 2 months ago. At first it was working fine, until i connected my external monitor. Laptop started to throtle after few minutes. I noticed that fans didn't work at all. I almost returned my laptop, until i noticed this post and tried to boot without monitor. So if someone is having troubles with throtling and overheating, try to boot without your external monitor and connect it back after windows has started. I hope Acer knows this issue and they will fix it.

    hi all, sorry for my english.

    I had the same problem during 6 month ! cpu 0.78ghz and full speedfan when i start windows.

    No good solution from acer SUPPORT (format pc, update drivers...)

     

    I tried to open the laptops, it is very hard, and i saw a horror, the thermal paste is improperly installed. I removing all, and i put correct new thermal paste on the CPU. 

     

    AND NOW IT WORK !!!!

     

     

    I am very disappointed by ACER support and this poor quality of material....
