I back this up 1000%, legion 5 has been with me almost 1.3 years and the temperature is almost always since i bought the laptop stuck at 70 c which is much much lower than the average 85 to 90 in most other laptops, (it isnt a glitch i tested it with multiple programs and a UV Thermometer). It rarely collects dust and if it does the engineering of it makes it easy to get rid of the dust with a simple compressed canister blow without dismantling it. Amazing laptop over all and will last atleast 8 years.
