Question

macbook

Hello everyone
Recently I bought a used MacBook Pro 2012 Retina 15 "
When you turn on YouTube video in 4K, the temperature of the processors jumps up to 105 degrees.
When you stop playing, it cools down for a few seconds .
Fan speed at this moment jumps to a maximum, up to 5'000
Is it normal it?
Thanks in advance

Too much, bring it to a normal workshop for cleaning and replacement of thermal interfaces.
But it's all relative. The maximum limit is slightly more than 105, in case of severe overheating, the laptop will simply turn off. Therefore, the temperature is tolerable. My 2012 background was 85 when running in the IDE
