Hi,

I have installed NetBSD 4.0_BETA2 on a Dell D510.
About 15min after the boot, the fan starts to blow.
I think the fan has 3 steps NONE/SLOW/FAST. When the fan goes into
that SLOW level, it never goes down anymore.

I have compiled a light-GENERIC (with sysutils/adjustkernek) kernel with
ACPI and I am running estd to keep CPU as slow as possible.

Here're a few infos about my config:
#  dmesg | grep cpu

I think that when it was running Windows, the fan went back to the
"NONE" state when the computer was idle-ing.

Do you think that this is hardware related or is there something in
NetBSD that I forgot to setup to keep this laptop it as quiet as
possible.

TIA,
	Jo
