I investigated more reviews and found some complaints about the thermal performance. It looks like a relatively straightforward fix might be possible, though not overly simple. It seems to require just 10 Phillips head screws and the entire bottom panel can be removed. The cooling system appears decent, so applying a fresh paste could help reduce the thermal issues if you're willing to try. You might also consider using Intel XTU or a throttle stop to lower the CPU voltage.
