Sorry, I'm sure this topic has been beaten to death and I've done some initial research, but would like some feedback based on my situation. I have recently installed some games on Bootcamp, Windows 7 64bit. I'm running the i5 Macbook Pro mid 2010 model with the 330m GT card and 256mb graphic memory. I'm finding that all Source games run very smoothly and am especially happy that Bad Company 2 runs at native resolution (1440x900) @ 30+ (and a very smooth 30fps at that, which seems a little odd for me). Anyway... I have been monitoring my gpu temps and I have hit a max temp of 89c, which makes me a bit nervous. However, when I exit out of a game the gpu temp seems to be around 70 or so and drops pretty quickly. Is it correct to say the reason for this is that the mbp fans don't kick in soon enough? Hence, the reason why I have hit a max of 89c, yet directly after exiting the temps look fine. I've done some research on fan control software and it sounds like lubbo's is a good option. Is the idea to keep the slowest fan speed at like 3-3.5k and lower the upper temp threshold to something lower than default? Here's a screenshot of the software: http://sourceforge.net/dbimage.php?id=224842. This is my first time using fan control software. I just want to make sure I understand. If I set it to 3.5k, it will start at that speed thus keeping temps cooler. Then by setting the upper threshold lower, means the fans will spin faster sooner, keeping the gpu cooler. Do I have that right? Thanks!!!
