Re: pavilion dm4 - loud fan

Hi! I have the same problem. The fan appears to be changing the speed every moment.

 

Is this normal?

 

Thanks

 

Mine is DM4-1065x

Re: pavilion dm4 - loud fan

I just got the dm4t-1000 custom configured yesterday. the fan has not.stopped.running, even when I am not doing anything and the CPU usage is at a steady 25%. It's really loud. It's driving me nuts. Any tips?

Thanks.

Re: pavilion dm4 - loud fan

P.S. It's on a hard, flat surface--a normal desk. It's 67 degrees in here. Normal.

Re: pavilion dm4 - loud fan

Did you buy the computer used or refurbished at all?

 

Many times a laptop overheating is directly related to the cooling of the processor. The main culprit is the fan. The fan sucks in air from the bottom and blows it out the side. It will also suck in hair, dust, and other debris. That stuff often gets trapped by the heat sink and over time builds up in a layer which chokes off the cool air going to the processor making the fan work harder.



What I recommend is getting some canned air and blowing out the vents in the side and bottom of the laptop. If after doing this you still have problems with over-heating, and your laptop is in warranty, you can take your laptop to a HP Authorized Service Center and ask them to clean the fan and heatsink. You can check your warranty here:

If it is out of warranty, consider searching for the maintenance manual for your specific model, in the manual there are schematics for taking apart the laptop. Cleaning the fan is much easier that removing a motherboard, so don't feel to intimidated by the idea. Also you can remove the heatsink and then remove the thermal grease and apply a new layer which also helps alleviate heat related issues.

    Re: pavilion dm4 - loud fan

    I bought a brand new customized Pavilion dm4t-1100 two days ago for personal use and the fan has not stop going, even when the computer is standing there doing nothing. It's the same when plugged in and when in battery. I also tried switching to integrated GPU as well as the dedicated ATI GPU; no difference. I know from personal experience that is not normal, as I worked as an IT service professional and got to clean HP and Lenovo laptop fans all day.

    I updated the fan drivers to no avail, and checked my BIOS version which said "F17." In the Software & Driver section of the HP website the BIOS version of the driver is "F.17A," is there a difference?

    The fan is really annoying and quite loud. I have an Intel i7 2.8Gz, 6GB of RAM, and the 1G Dedicated ATI GPU. Any feedback would be helpful.

     

    Thanks.

    Re: pavilion dm4 - loud fan

    Have you checked the BIOS for a 'Fan always on while using AC power' option?  Have you checked Task Manager to see if there are any processes running that would cause the machine to use 90%+ of the CPU?
