Hi Installed Windows 7 Professional via BOOTCAMP on my new Macbook Air 2011 13" i5 (base model). All updates to Windows 7 and Apple software updated. In OSX the Air is silent all the time, and the alu-body is room-temperature-like. But in Windows 7: When starting from cooled alu-body the Windows 7 causes no fan-noice the first 5-10 minutes. Even running Windows completely idle with 0-5% CPU activity the alu-body gets very hot in the top-left corner. Slowly the fans kicks up in speed, and becomes very loud. Just doing some few things in Windows 7, causes the alu-body to get extremely hot, and the fans at the highest speed = very loud. CPU activity is still very low at 5%. No flash-browsing or anything else. Scenario 1: Idle in Windows 7, hot alu-body, high-speed fans. Restart to OSX, OSX starts. Slowly the fans start to slow down in speed. In 2-3 minutes the fans are silent and the alu-body is cool. Therefore, I do not think it's a driver-issue with the fans. The speed up because of the heat... Scenario 2: Idle in Windows 7, hot alu-body, high-speed fans. Put to standby. The fans goes off due to standby. Open the lid after 10 seconds standby - Windows 7 starts - fans are silent even though alu-body is very hot. Hmmm? Anyway: My dream was to do a little gaming at low graphic-setting, which the CPU can easily do on my windows-laptop with C2D ULV 1.3 GHZ. But the fans are very loud, even when idle in Windows. What is causing this? Bonus: Previously I have owned a Macbook Pro 2009 with two internal graphic chips. The high-performance graphic-chip was ON as default in Windows 7. That explains why the Macbook Pro got hot in Windows 7. But that is not the case in the Macbook Air...? Drivers: I let BOOTCAMP assemble a USB-disc with Windows 7 .iso, which means BOOTCAMP integrates apple-drivers. After Windows 7 installation, I installed drivers via the application created by BOOTCAMP in the USB-disc. What can I do? Has it something to do with the CPU-settings?
