HP omen 15 2018 laptop air flow and heating issue

HP Recommended
Omen 15-dc0022na 2018
Microsoft Windows 10 (64-bit)

The laptop has huge heating issues. Earlier I was confident that the rear vents are the exhaust but the air is no more flowing out of those vents. The bottom underbody vent is where the air is coming out of. Not sure if this is how it has always been and I have a false memory of the rear vent being the exhaust or the fan direction is reversed somehow now or there is some choking at some point. The laptop is unusable. Can someone please confirm where the exhaust of this model is, also if it's possible that the fan direction might have changed?

Also, download and install HP support assistant on your PC. It should automatically download and install the latest updates and drivers for your PC.

I have this PC as well, over the years I've noted the CPU temp has been slowly creeping up.


I highly recommend using a can of compressed air to duster the exterior of the fans every month or so.

It got to a point I was hit 90c with no load, but opening it is very easy with a small screwdriver.

There was an excessive build-up of dust in and around the fan. The can of air was enough to clear it.

CPU temp dropped 40c in one cleaning. I also bought a small cooling base, as my pc gets warm when using multiple screens for extended perionds. 


Good luck!
