Hi,
I hope that this helps some people.
My laptop has always overheated after a half hour or so of use. After reducing the performance settings, that helped and also delayed the onset of overheating but didn't resolve the issue. It also slowed my work pace, which always annoys me.
There is nothing like peace of mind, so I reached in back of me to a cabinet where I have a small household fan. I got a couple cardboard boxes to set the fan and pointed the thing at the bottom of my laptop. SHAZAM ! No more overheating ! Now I run the laptop at full performance settings in every category with no problem.
I am the kind of guy who hates waste and I love efficiency, so I turn off the lights or anything else when not in use. This time, I badly needed a fan! It's a very important investment for my workflow.
A quick note: I have come across all kinds of computers which overheat (sometimes). This includes a smartphone! If your device starts just fine and is okay for a while then slows, this could be overheating.
Grab that fan and see if that works for ya !
