Question

FACT: replace your logic board --> your fans will never stop

There's a new UNIVERSAL problem among MacBook Pro users. Over the last 60 days, logic board replacements in the MBP have led to constantly-running fans. How can we inform Apple of this new, systematic problem?

BONUS: If any Apple employee reads this: GET PROMOTED NOW! There's a systematic fan-chewing defect in the new (replacement) logic boards! Be the first to tell your masters in management! Orange alert! Orange alert!

(FYI: Yes, I reset the SMC.)

MacBook Pro 15", Mac OS X (10.5.5)

If you think this is an anomaly, try doing a search:
"macbook pro logic fan constantly run|running"

Also, my GF works for Apple here in Austin. They DO treat reports of SYSTEMATIC flaws differently.

If I'm not mistaken... the fans never stop regardless of whether or not the logic board is replaced. For all MacBooks, the fan is always running at a low RPM unless more cooling is needed at which point the fans will speed up.

Regarding Apple treating "systematic" reports differently... only Apple can determine if a problem is actually "systematic". Users commenting that a problem is systematic means little to them.

Perhaps this is true. I hadn't checked for low fan speeds until now (I just downloaded and installed iStat Pro). However, my MPB never hit audible fan speed unless it was actually ... hot. Now, even after a COLD boot (65 degrees F), my new iStat widget shows my fans at 6000 RMP. The acceleration from 0 to 6000 begins as soon as I type my password at the login page.

So the new loud fan sound really did indicate a fast-running fan. And this instant super-revving is actually NEW.

Apple recently replaced my logic board due to the Nvidia chip issues(started up one day and had no video). One interesting note- A genius told me that the no-video problem was a logic board issue and that there was a power issue and would cost me $385 to repair. I let him know that the problem is the Nvidia issue and should be fixed for free. He argued that the logic board was dead. My response was, "If it were machine starts up and joins my wireless network, how can the logic board be dead?" They finished $1,700 worth of repairs in a day.
Got it back and now the fans run constantly. Took it back to the Genius' in Sherman Oaks and they tried to tell it was the fan itself. They said they could do it next day, in-store for about $200 and he printed out a work order. I mentioned that I read online about issues with the fans after logic board replacement and he did something on hisProxy-Connection: keep-alive
Cache-Control: max-age=0

aptop. Now he says that they could send it to their factory and they will fix it for free, but it would take a week. I took it home to backup. Haven't gone back yet

+replacements in the MBP have led to constantly-running fans. How can we inform Apple of this new, systematic problem?+

1. The most likely cause of fans running 100% after a repair is that the fan sensor lead has not been reconnected to the motherboard.

2. I doubt it's "systematic" as that would imply all repairers make the same omission.

I agree with iVmichael. I recently had my logic board replaced, and while I've had a host of problems with the machine, fans running constantly is not one of them.

Just to be clear, the fans in an MBP ARE designed to run constantly. Any time the MBP is on, the fans are on. Idle speed is 2000 rpm. Max speed is 6000 rpm. If you mean that the fans are running at 6000 rpm constantly, say so. But when you say that your fans are always on, I say, "That's right. They are, and that's the way it should be."

Why don't you just report your 'systematic' problem to her?
