Question

Asus U38N fan runs at full speed all time, Win 8.1

Feb 19, 2015 2:45AM PST

So my Asus U38N has a fan that is running at full speed for a few days. It's located below the upper right corner of the keyboard, below Esc and numerical keys. It runs on Win 8.1 64. I checked temperatures with OpenHardwareManager and they're ok, also the CPU, RAM and harddisk usage is normal. I attach a screenshot. Anyone has an idea what can be wrong?

Looks proper in that window.

I see the cores are all clocked up and running so I have to write it would be proper for the fan to run at near its top speed.

All it would take is some app to be running to cause this but the clues so far only tell me that I would expect the fan to do this.

Maybe you need to look deeper at what's running?

Task Manager
Feb 19, 2015 6:45PM PST

Ahh you referred to Task Manager. I already checked it completetly (the on in win 8 is mroe complete that the on from win 7 I think) and everything is correct!! There no processes or applications that consume high amounts of cpu/memory/disk! Any other clues where can I check? :/ Thanks for help!

There's more to explorer than task manager.

I can't see what you see and since there are non-user processes (show all processes, noted at http://www.sevenforums.com/general-discussion/2223-task-manager-show-processes-all-users.html )

So there's that and then more advanced tools like PSLIST noted at http://superuser.com/questions/294991/list-running-processes-with-cpu-and-network-usage-in-command-line

However restoring the machine to factory condition is sometimes the only out. With all the spyware, malware and such today it can be a lot of work to find what changed. Sometimes it's something we installed but here I only can see what you share. There are so many apps that could trigger this that I can't guess it without more clues.

Even something like leaving an USB HDD plugged in can trigger this. Why is on the web. In short, we look for what's not stock.

Bios fail
Feb 20, 2015 9:10PM PST

Dear Bob,

thanks for all the help. I know there are more proccesses in task manager and already checked them. Anyway what u say makes a lot of sense and I appreciate your help. For now I received response from ASUS technical centre and they told me to upgrade my BIOS so I'll be doing this tomorrow, hope it helps. If not I'll continue searching for solutions. Will update the topic when found something new. Great thanks!!
