Y580 overheating, vents issue

Hi all, I received my new Y580 about a week ago. I use HWMonitor to check the internal temp. The highest temp ever record is 81 c for the CPU (when gaming). Which I think is pretty high, consider that I have the laptop elevated about 3 inches off the table and my room is pretty cold (it's winter here). So I checked to see if the bottom 3 vents are working properly. I figure that the bottom vents draw air in to cool the inside. So if I have a small piece of paper, it should stick to the vent because it sucks air in. The piece of paper only stick to the top vent (the one near the exhaust vent on the side of the laptop), but not the bottom 2. Also, the top vent feels kind of cool to the touch after prolong use, which make sense because it's drawing air in. However, the lower 2 vents don't feel the same and actually feel kind of warm. This lead me to believe the 2 lower vents are not working properly.

I posted this question on another forum, this is what someone replied:

"your Y580 seems to do fine...

minimum CPU temp at idle should be around 45 degree C, maximum temp at continuous full load can go up to over 90 C, depending on ambient temperature.

The bottom vent near the exhaust is located just below the fan and naturally the most cooling air gets sucked in from there, whereas the other vents just let outside air get to various component inside the laptop without forced airflow."

Does that means only one of the vents draws air in, while the other two really don't do anything? So what is the point of having 3 vents?

 

he already explained it

The hard drive and ram require passive/low airflow to dissipate some heat.


cpu max temp is 105c. Bios throttling starts at 90c. You're not even close.

When you ever get to 95c, then start worrying. (then proceed to blow the dust out)

 

CPU temp at 81C is pretty damn cool when gaming.
