After cleaning a massive amount of thermal paste off the cpu an= d=20 heatsink it's operating around 60C after multiple make -j4 buildworlds, whe= re=20 it used to shut down due to going over 100C. It seems I'm not the first person to discover this was the root cause of th= eir=20 heat and noise problems with their Lenovo T60/61 laptop. I've also been able to turn over control of the fan back to the BIOS as=20 opposed to running it full out all the time. =2D-=20 Thanks, Josh Paetzel PGP: 8A48 EF36 5E9F 4EDA 5A8C 11B4 26F9 01F1 27AF AECB --nextPart4720874.lf9a3LYWdm Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (FreeBSD) iEYEABECAAYFAkhMPXUACgkQJvkB8Sevrsv7iwCeJI5Xnrm9g6uxqv7FtZKZKE5c nqcAoIod/MjVP3jfQkbIHwVJ69VYb12G =lcFC -----END PGP SIGNATURE----- --nextPart4720874.lf9a3LYWdm--
