kesava108 Posted January 2, 2009 Share Posted January 2, 2009 (i posted this in official apple forums, thought i'd post here for a second opinion, btw i have googled ) Hi just got a new macbook, late 2008, and encoded 3 vids to play on sons ipod. Not until the 3rd one when i had everest installed, (using xp under bootcamp), that i noticed the cpu temp rise to and maintain a value around 100 degrees celsius. i have taken steps via software (smcfan and that tweaking software that goes with it) to increase fan speed uunder xp. Should i be worried that my macbook will have a shorter life span considering i had it at 100 degrees c for bout an hour? (Also, Is this a fault in my particular macbook, ie warranting a replacement?)

shavex Posted January 2, 2009 Share Posted January 2, 2009 First off that has to be wrong, the Intel CPU's will not let you run over 90C for more than 5 seconds without shutting the computer off. Have you tried using CoreTemp to see the temp values?!

Berzerker Posted January 2, 2009 Share Posted January 2, 2009 First off that has to be wrong, the Intel CPU's will not let you run over 90C for more than 5 seconds without shutting the computer off. Have you tried using CoreTemp to see the temp values?! Wrong. The official threshold for the Intel Core 2 Duo CPUs is 115C, in which case the computer will shut off automatically.

kesava108 Posted January 3, 2009 Author Share Posted January 3, 2009 now that that has been sorted out, can any great soul address my (prolly newbie) concerns Link to comment https://www.insanelymac.com/forum/topic/144261-should-i-be-worried-bout-high-temp/#findComment-1024442 Share on other sites More sharing options...
OSXtasy Posted January 3, 2009 Share Posted January 3, 2009 Yes you should be worried about the high temps. Apple's hardware cooling controls(SMC) has sucked since the first Intel Core Duo's. I don't know why they cant get it right but they cant. The main reason is they make the notebooks thin (form over function) and then stuff low end Delta fans inside, and are now using nvidia chipsets as well as graphics cards. EDIT: For Bootcamp Windows use, download and install input remapper to adjust fan speeds when booted into windows. When in OSX: Do yourself a favor and download and install SMC fancontrol. Set it to never run under 3200rpms(keeps mine in the 40's under basic load), and even then if you are gonna be gaming (not advised due to heat issues) turn the fans up to 5000-6000 before beginning a gaming session. Turn them back to 3000 or so after gaming ceases. Your laptop will last alot longer, and you can avoid having to deal this "black screen" syndrome from overheating, as well as Apple Care's {censored} poor explanations...... Long story short...HEAT KILLS ELECTRONICS. Even if the thermal envelope allows for 115celcius, you are damaging your equipment by then. Don't let it get over 60-70 celcius or you risk damaging components. Of course Apple says it's ok, they want it to burn up right at end of warranty so you will buy another one (STOCK PRICE BUMP for them). Plus Apple Care is part of their MAIN REVENUE!!!! They are nice laptops, but Apple's Quality Assurance is NON EXISTENT in respect to cooling........ITS A FACT. If you wanna use a "new" mac (reliably) you have to take responsibility for making sure it runs cool yourself..... I do this for my MBP and My MacPro (although speeds on MacPro only go to 3000rpms due to larger fans) {censored} BUT TRUE!

kesava108 Posted January 4, 2009 Author Share Posted January 4, 2009 thanks bro, prolly will talk to the local mac guy about it and see what i can do, thats {censored} that the fans dont crank up properly under windows. I am using input remapper now, and trying to find and use more mac apps.

Berzerker Posted January 4, 2009 Share Posted January 4, 2009 Personally, I would not be worried with the heat. I've had Macs go up to 100C before, as long as it's not going over and hovering around there on load, then it should be fine. If the idle temp is around 55C, there's nothing wrong with your cooling system. Boot camp is notorious for letting the processor get a little more hot than it would on OS X, since the SMC works better with OS X than Windows. My 2 cents is that see if any problems arise. If nothing, then leave it alone. Link to comment https://www.insanelymac.com/forum/topic/144261-should-i-be-worried-bout-high-temp/#findComment-1026925 Share on other sites More sharing options...
22HERTZ Posted January 6, 2009 Share Posted January 6, 2009 OSXtasy is exactly right and I agrre with everything he/she said. Im an EE and will tell you there are two things that kill electronics...voltage transients (lightning will do nasty irrepariable things) and heat. Keep those two things out and electronics will last a long time. I do just what OSXtasy says with SMC Fan control...I keep a minimum of ~3700 RPM and have a max fan setting when I do anything more intensive than simple stuff. Keep the heat out and it WILL last longer, and that goes for any electronic device.
