Those processes will run until you quit each with ctrl-c. If the clicking never stops after running the fans at a high speed for a while, take it back. There could just be a cable brushing against the fan.
Hi Marvin, i also am having this issue, however:
I assume terminating each shell in terminal (no pun intended) with control+c is equivocal to quitting terminal all together. I ask because after reboot, fan noise was significantly louder, and hasn't gone away since. I worry that rather than this being a lingering command (which from what I know of the OS leads me to believe this is not the case), I instead shifted a rubbing coil or particle (or perhaps the high temps from fans on previous burn melted remaining adhesive). However, after tipping the computer on it's side and tapping/gently pounding the backside of the laptop (I know this is not advisable, but it seemed the only logical solution at the time), the noise rather suddenly disappeared. I then very cautiously returned laptop to normal position, and lion purr did not return. However I feel reluctant to move the computer from the table, lest the meat grinder come back with a vengeance!
By the way I'm a PC builder, so not super familiar with shitty MacBook internals, but don't hesitate to use complex descriptions if you have knowledge. I'm just about ready to tear this thing apart, given the warranty was void many years ago.
I know this post is ancient but so is this laptop. Any help would be appreciated. Thanks.
