omen 15 cooling fan issue

[mihir7]

I have an omen 15 laptop and I checked the fan speed using SpeedFan and while fan1 is spinning with an rpm of 2000 while fan 2 has 200 rpm under normal use(web browsing). So, I was wondering if both the fan should have equal rpm or if it is normal.

Thank you.

No, fans are controlled by heat sensors. Machine has 2 areas and each area has a heat sensor, they do not use same sensor nor same fan therefore fan will have different speed depending on how hot the area is.

Hope this makes sense.

hey man. I have the same problem with my Hp Omen DC0052nr laptop. One runs at 203 rpm max and another at 2002 rpm at normal gaming and web surfing. While I opened up the back I saw so much dust clogging the inner side and gave it a clean. But no change in speeds. So I thought it was some software limitation. But I checked the fans again and found it to have some resistance to spinning. So I am planning to lube it with white grease and check if that works. You too try it. Or else it must be like what the expert said, that it is limited according to the heat.
