Late 2009 iMac running slow after moving it

Sorry Charlie, but I guess we'll agree to disagree, but I'll say and I agree with Rod that that running cooler is better when it comes to CPU’s and most electronics. And that includes all our Macs.

Well, I guess you and Rod know better than the Apple engineers who designed the entire system. Maybe we can get you and Rod a job at Cupertino?

Well, I know I don't know as much as the Apple engineers regarding my Macs, but then again I'm not looking at or concerned about selling more Macs either.

I do know that if and when it's too hot to rest and leave my hand on the top of my iMac (and all vents are clean and all fans are running), it's too hot for any internals for any longevity or proper working — even if it is within the limits that Apple engineers happen to set. So I'd say Rod and I and a lot of others do know how to deal with our Mac's internal temperatures.

No thanks to any job there thanks.
Two of my sons have some computer friends that have worked there and some of their stories are not even repeatable. If it was even allowed!!!

Two reasons not to use a Fan Control App to boost the fan's RPM:

1. Increases the noise level

2. Fans wear out faster

If you happen to have an iMac that you changed out the hard drive and neglected to compensate for thermal sensing, then the Fan Control app can keep the fans RPM down to normal levels. Macs Fan Control works real well for that purpose.

So I'd say Rod and I and a lot of others do know how to deal with our Mac's internal temperatures.

Hey.. it's your machine and what you do with it is your business but giving out advice to others without a full explanation and implications is not good advice. ;D

As for your two listed reasons:
1, We have absolutely no increase with any fan noise level with any of our Macs.
2, reading some valid information that would backup such a statement would be beneficial to some I would think. And I'd really question if a few hundreds RPM would really make much difference to the fans longevity.

And my advice was certainly provided with explanations and reasons.

Anyway, it's the users choice whether to use such a utility or not. I just like and often recommend a method to keep my Mac running cool which I suggested.

I'm with Charlie on this one. Never saw any need for fan controls on a Mac. The engineers balance the impact of heat on component life against the impact of higher running on the fans and find a sweet spot where the fans and components both last the longest. Just leave it alone, let the system manage the fans. Any third party software that meddles will have a non-optimum outcome in the long run.

Just want to update, I installed the new HD this morning, restored from time machine and it’s up and running like new, went with the 2TB Toshiba for $13 dollars more. I also did a a SMC reset make sure the the fans operate properly. Can anything be done to the HD or is it just trash?

Destroy it if you can't securely erase it before throwing it away. Do not attempt to use it again.

Thanks again to everyone for your assistance.

Sure, take it apart and remove the very strong magnets that are very useful for all kinds of things.

Just be careful to keep them away from any small children. They really are strong!!!

Wow, thanks for the tip Patrick. I’ll be sure to do that myself next time I have a HD to dispose of. Magnets are really handy, especially good ones.

You're welcome Rod, but be aware if you use them as refrigerator magnets and without any sort of handle, they will not let go easily!!!

So, it best to glue them to something.

BTW: I was demonstrating two such magnets to a friend years ago with one in each hand, and when my hands got close together but still some distance away, they flew together and smashed into several pieces from the collision impact.

I use an external fan to help moderate computer heat, when necessary. I don't use any internal fan control, because the fan(s) speed needs to be able to fluctuate, going up or down, depending on the fan location(s) and what component is being stressed to raise the heat.

Hmmm…??? I'm not sure if doing so will even affect your Mac's internal temperatures very much Bob.

BTW: The Mac Fan Control.app will vary the fan(s) speeds as set and according to the various internal temp sensors, but they cannot be set lower than Apple's OS X default settings.
