So after installing FanControl and raising the base speed for the fans by a measly 200rpm to 2000rpm, this is the result. Temperatures are in Fahrenheit. For those outside the US, that's ~35C. Sometimes it drops to 33.5C. For those using Fan Control, here are the settings I've been running. I mostly do SQL Server and .NET development in VMWare that uses a Boot Camp partition. Upgrades are 8GB of memory and a Seagate Momentus XT. This is the 2.0GHz with an AMD 6490M Base Speed: 2000 RPM Lower Threshold: 45.0 C Upper Threshold: 75.0 C If with these settings your idle temperatures are considerably higher, there is a chance that your CPU and/or GPU may have had an obnoxious amount of thermal paste applied to them during assembly.
