I can't tell you what your temps are going to be, since that varies with every situation, but I can tell you that in general, it's relatively quiet. The fans are thermally controlled, so as temps rise, fans speed up. You can actually set in the BIOS what temp you want the fans to speed up at. When the fans are moving fast, it's semi-loud, but not bad. When they're just going to keep things decently cool, it's pretty quiet.
