Two seconds of Google power led me to an app called Fan Control that allows you to establish a temperature to fan speed curve. I set my minimum to 1,000 rpm, and anything over 120 degrees would raise the speed, with 172 degrees at the 6,000 rpm cap. Generally, with Parallels running and the other usual stuff, the fan is now running between 1,500 and 2,000 rpm, which is a lot more in line with what it did before the repair. It doesn't get audibly louder until 2,500 rpm.
While this will naturally impact battery life, it'll also preserve my nuts. I'll take a few less minutes of portable computing to preserve my goodies.
