I have a Dell Dimension 8400 ...It seems That the main case cooling fan wants to lift off like a saturn 5 after about 30 min of game play...temps are coming in at about 100 on the HDD and 126 on the GPU .yet the fan continues to increase speed ??? There is an aux cage cooling fan that is running low and slow...? I am confused as to what to do. I read online there is software to control fans...anybody got any real life experience doing this? What and how do you use it? Anybody got any leads on a system specific version for a Dell 8400 ? Or would there be something more sinister going on here? Thanks
