Product: HP Pavilion 15-dk0056wm
Operating System: Microsoft Windows 10 (64-bit)

I have a brand new HP Pavilion 15-dk0056wm and I get the dreaded 90b system cooling error. I know this is a common topic but as far as I know this happens when the laptop has quite some age. This is a brand new computer. And the error appeared one day after I got the laptop. As per the HP support site aside from defective fans it could also be that the fans are dirty (I've cleaned them using canned air just to be sure) or a software problem. I've already done a firmware upgrade and also upgraded Windows to version 2004. The fans are working but I still get this error. One thing I've noticed though is that I often get this if I do a cold start meaning the computer hasn't been used for quite some time and there is no need for the fans to work. Once the computer is "warmed up" after some use, rebooting doesn't show the error. I have also noticed that the fans start to work when the temps reach around 55C. Any ideas? I still want to explore options to prior to either returning thsi laptop for another one or sending it for repair. Thanks.
