Well most BIOS have a few options for controlling the fan speed and will certainly let you set a temperature to warn you. My limited experience with the 8150 so far is that it is a nice enough cpu, runs hot under load and that the stock cooler will be impossible to live with (barely adequate and I know exactly what you mean by noisy!!).
I'm looking at better cooling, that is reasonably cheap and preferably not too large, such as the hyper 212 evo etc. Really doesn't help with the lack of decent temperature information about on the FX series, think even AMD is a bit vague about it.
