If you're gaming in Windows and you are on a MacBook Pro with a throttling CPU, then there is a trick that you can use to keep the fans very low when playing a game that doesn't require a lot of CPU power. Go to your power options in the control panel and crate a new power plan. Call it something like "low power." Then in the advanced options set the CPU's maximum percentage to 15% and the minimum to 1%. What this effectively does is keep your CPU at the underclocked state. I have a new i7 2.2Ghz CPU and it has essentially 3 states: Underclocked at 800Mhz, Normal at 2.2Ghz and Overclocked turbo-boosted up to something like 3.3Ghz. When its in the underclocked state it doesn't generate enough heat to turn the fans to high. For most PC games you don't need much CPU power so it works great. I play Dead Space 2 and Mass Effect 2 both without problems in the underclocked state and with graphics maxed out. Even Rage runs pretty good. Additionally, if you set it to 99% then it will prevent the CPU from turbo boosting keeping the fans a little lower also. There is a utility out there that you can manually set your multiplier so you have 200Mhz increments, but I forgot what its called. Point is, set your CPU to as low as you can for the game to be playable and enjoy quieter gaming.
