Hi all. I've recently purchased a HP Probook 440 G5 (256GB SSD), just 1 week ago to be exact. So far the notebook has done the job well. However, there is a extremely annoying issue: the fan noise. When my laptop is plugged in, it keeps getting really loud despite that there is no heavy processes going on; I've already monitor the Task Manager. At first I thought that happened due to an option called "Fan always on when AC Adapter ..." inside the BIOS so I double-checked and found out that is not the case. I tried to update the bios to the lastest version, reinstall the windows and update all the drivers both manually and automatically through HP Assistant. Any help?
PS: I hear some clicking noise when the fan gets really loud; its like the sound of a dying HDD but really small. Its a brand new laptop so I suppose its not the SSD issue, but I am really out of idea now. (Getting it repaired is my last resort; I live in Vietnam, where technical support from brands' manufacturers is typicall weak and time-consuming)

Hey,
I´m having the same issue that the fan is sometimes blowing with full power without any processor load. This seems to be a second bug in relation to the Intel Dynamic Platform Thermal Framework driver on Intel Core processors of the 7th and 8th generation. The other bug is that sometimes the system process creates after boot or sleep a processor load of 25% after a deferred procedure call presumably caused by a faulty (sound?) driver:

I really hope that HP, Intel and Microsoft are working very hard on this problem, otherwise I will return my device at the end of the 4 week trial-phase and switch to another hardware vendor.

I have the same issue with a brand new 440 G5 with pre-installed Win Pro. Audio drivers are buggy and causing high CPU usage: process System or sometimes flow.exe are consuming 20 % of CPU. As a result, the fan is almost always on.
