They did, but then I found what seems to be the original issue. Adding an 80G Intel SSD to the system was really the problem. Even though I couldn't detect any excess heat where the drive sits I thought to myself, "I wonder if a machine this small is finely tuned to every component?" So, I replace the SSD with a 5400 RPM Hitachi Travelstar (160G). Voila. Building enlightenment and doing a make -j 4 buildkernel brings the temperature only up to 71C at the very highest. It would seem that speed really does kill :-) Best, George --Apple-Mail-25--16972943 content-type: application/pgp-signature; x-mac-type=70674453; name=PGP.sig content-description: This is a digitally signed message part content-disposition: inline; filename=PGP.sig content-transfer-encoding: 7bit -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (Darwin) iEYEARECAAYFAklqJfEACgkQYdh2wUQKM9JnqwCcD/4cxCiUNwBVXjY9fKRBl1Gv wlQAoLzYtlDX/fwR6iDHZNdjDpP4W3Pt =Yy2v -----END PGP SIGNATURE----- --Apple-Mail-25--16972943--
