Hello,
I have PentiumD 805 (2.66) with an intel fan.

A couple of days ago i removed the HS and fan in order to clean them, and returned them afterwards.

A few days later my cpu temp. began rising, its now 55 in idle, and the fan is at 4000RPM instead of ~2500-3000RPM.

Maybe by removing the HS i've damaged the thermal greeze texture or something like that ?

Or any other ideas ?

Thanks in advance :)

You should definitely clean off all thermal grease with a coffee filter and then re-apply.

I think the thermal grease reacts with the air and then it doesn't work as well if at all

After applying AS5 the temp droped to 46c.
now, after a few days it droped to ~41-41c in idle
i hope it will drop more

Yeah the drop in temps is referred to as a "break-in" period by AS5's own manual. You can see the same effect on my Q6600 in this thread: dropped by an average of 2.3 °C after about 300 h of use.
