Z61p fan noise

[malandro]

Hi,
I'm very happy with my new Z61p (model 9452-J6G) except for the fan noise. The fan kicks off at a loudy speed after having used the laptop for about 1 - 2 hours (internet browsing, Outlook, Word...).

After leaving the computer resting, the fan speed does not go back to lower speeds but stays at same speed. No hot air coming out from fans, no hot parts...

Has anyone experienced such behaviour?

Thanks for your help.

No. The fan on my Z61p 9450-CTO seems to turn on and off appropriately.

you should check your task manager and see if any processes are using up cpu power(even at idle some rogue processes might eat up cpu power). fan might be on constantly to negate this.
if this doesn't work. use tp fancontrol...

btw, what's your cpu temp when the fan kicks in loudly? more info would help pinpointing the problem...

thanks jkahng,

cpu usage in task manager is ok. Around 75 tasks are running but all of them smoothly, 0-2% of CPU ussage in total.

I can differenciate up to 4 fan speeds. The first 2 of them are ok, not so audible. The third one (rather noisy) is the one that kicks off always (sooner or later) and from here there is no way back to 2nd fan speed. Sometimes (with heavy CAD usage and 3D animations) fan speed jumps to fourth level but it returns to 3rd level.

What I think is that 3rd level fan speed is noisy enough to be constantly there.

I do not have administrator right to the Z61p, so I cannot use ftpfan control and I haven't found any temperature-displaying software which works with non-administrative accounts.

Tanks again for your comments!

looks like you need to get admin rights

i've read here on the forums that rolling back to an older bios version can remedy this problem. (not recommended if you have core 2 duo)

you can try notebook hardware control and play with the various power schemes. max battery should make the fan rotate at a slower speed. (it shows cpu temp on the task bar so it should give you a better idea of what's going on)

hope this helps...

The fan on my Z61p runs fine too.
However, when I replaced the original seagate momemetus 7200rpm 100 GB hard drive with a larger 5400rpm toshiba hard drive, the fan was constantly running (felt it with hands, after sensing the system was getting hotter than usual).
Sent back the HD, put back the original and everything is back to normal,, Wierd.
