I just downloaded fan control because it sounds like a good idea to keep this puppy cool. What is a good setting that isn't going to be overkill. I don't want to compromise battery life too much. Anyone good with this program? This is for my MBP 15"

MacBook Pro 15" / iMac G5 PowerPC, Mac OS X (10.4.8)

    From what I've been hearing 3000 rpm is a good point for the fans to run at. Honestly they should be able to run at the full 6000 without problems but the first SMC scripts didnt recommend RPMS over 4000. 3000 should keep your laptop very cool. I had my minimum fan speed at 1500 and still got noticably cooler temperatures.

    Best of luck

    My setting:

    Base speed: 1000
    Lower 54°
    Upper 80°

    Normal temperature around 60°

    Full load around 68°

    I am fairly new to the Mac world, this Mac Book Pro being my first Apple computer.
    I have been concerned about the temperature, I have experienced no problems because the temperature but the long term effect were always on my mind.
    I have followed the various threads and suggestions being offered on ths forum, I have downloaded fan control, with the fan speed settings etc suggested above my temperature has dropped from 58 C to around 50 C ( I already have been using a cooling lap top stand ), this may seem a simple question but is there a temperature that the machine should not run below ?

    You can't make your macbook too cold by using the fans unless you are working outside in freezing temperatures. The fans won't do that though. However, you can use more battery life the fast you make your fans work so you want to balance them at the appropriate level for how much work you are doing on your mac at one time. If it seems to be getting warmer because you are using your mac more try uping the rpm up to 500 more from the last setting until you notice it getting cooler. Hope that answers you question.

    Ive heard from numerous sources that installing the fancontrol utility voids warrenty. Ive been told that anything that alters the firmware in anyway voids warrenty.

    Ive heard this from an Apple Support tech, a top level developer with Apple and my local mac store tech.

    Just want to put that out there in case its true =)

    From the "standard warranty" exclusions on Apple's MacBook Pro support page:

    This Limited Warranty applies only to hardware products manufactured by or for Apple that can be identified by the "Apple" trademark, trade name, or logo affixed to them. The Limited Warranty does not apply to any non-Apple hardware products or any software, even if packaged or sold with Apple hardware. Manufacturers, suppliers, or publishers, other than Apple, may provide their own warranties to the end user purchaser, but Apple, in so far as permitted by law, provides their products "as is". Software distributed by Apple with or without the Apple brand name (including, but not limited to system software) is not covered under this Limited Warranty. Refer to the licensing agreement accompanying the software for details of your rights with respect to its use.

    This warranty does not apply: (a) to damage caused by use with non-Apple products; (b) to damage caused by accident, abuse, misuse, flood, fire, earthquake or other external causes; (c) to damage caused by operating the product outside the permitted or intended uses described by Apple; (d) to damage caused by service (including upgrades and expansions) performed by anyone who is not a representative of Apple or an Apple Authorized Service Provider; (e) to a product or part that has been modified to significantly alter functionality or capability without the written permission of Apple; (f) to consumable parts, such as batteries, unless damage has occurred due to a defect in materials or workmanship; or (g) if any Apple serial number has been removed or defaced."

    I see nothing there about "firmware" specifically. "...non-Apple products" could refer to any third-party software.

    Some might argue that (e) applies, but these fan utilities don't "significantly alter functionality or capability". None allows settings below Apple's default 1000 rpm setting. Nor do they defeat the default Auto fan mode, which increases fan rpms as the temperature increases.

    Most of the people passing on warranty scares are well meaning, but the facts don't support their contention.

    These fan utilities in no way resemble the thermal paste mods that were kicking around these forums a few months back. Remember? And even then, some here maintained that mod (where you actually open the machine) did NOT void the warranty as long as there was no damage done.

    Heck, Apple doesn't even warrant their own software!

    What exactly is this an control program. I find that my Macbook Pro gets quite warm with minimal usage. Where exactly can I find this program?
