High CPU temperature and high fans level

I was trying FreeBSD 10.3 on my laptop (hp probook 4510s) and was surprised
to see high CPU temperature and fans running high.

No apps running, I get a temperature of 57C in dev.cpu.x.temperature and
fans run high (not able to get rpms).

On a 4.6.3 Linux distro I get an average of 48C and fans are quite low.

Both tests were kept in tty. No Xorg running just a boot and user login in

Do you have any clue?
