Hi, it's been seven months since I purchased "Acer Predator Helios 300 PH315-52". Two months ago I sent my laptop to the service because of thermal issues and fan malfunction. They replaced both fans and thermal paste. All were good until Acer released a new BIOS update. Before the update, my laptop was working enough cool and stable and both fans had 6000+ RPM on turbo mode. But now CPU fan fluctuates between 5700 and 5800 RPM on turbo mode and thermal performance is not good as before. Even current OS does not work properly, sometimes the system freezes and when I restart it stacks on black screen for several seconds. There are a lot thing which I haven't mentioned but my question is that can I replace BIOS with older release?
Thanks in advance.
