I have a HP 8730W Laptop that has been installed with Windows 7 since RTM. Over time, all updates has been installed. Lately, I have noticed quite an increase in the CPU fan usage. Earlier, when idle, the fan was not noticeable at all. But now it spins all the time.
I just installed Core Temp and right now when I only have Outlook idle, and writing this in Internet Explorer 9, it reports that the idle core temps are 60° and 61° C (140/141°F). I have no clue what temperatures I had before, but the Laptop itself is indeed much warmer now than before. So here's what I have tried:
- Opened the keyboard/case and looked to see if there were any dust collecting up in the fan, but it was surprisingly clean.
- Re-paved with Windows 7 SP1
None of these have helped.
- Intel Core 2 Duo T9600
- nVidia Quadro FX 2700M drivers 261.28
- 8GB DDR2 RAM
- Intel 160GB SSD G2
Running resource monitor for a while shows that the top average CPU usage consumer (some ~6% now when idle) is
iexplore.exe. So the obvious thing would be to rollback to Internet Explorer 8. But if I use Chrome instead, it doesn't change much of the behaviour.
EDIT: Uninstalled Internet Explorer 9 and after reboot, average temp is still 61C just idling.
Has anyone noticed something similar or can give me some advice?
