OS X V10.7 Lion :: CPU Operating Temperatures Related To HDD Health?
Apr 22, 2012
I just had the original HD on my iMac fail suddenly. Apple was great in getting me a replacement quickly. My question concerns the normal operating temperature for the iMac's CPU before versus after the replacement of the HD.I use smcFanControl just to monitor the CPU temps. During the two years I used the original HD, the CPU temp never exceeded 140F. Within two days of running the replacement HD, the temp has been up to 152F several times.
I have great faith in the engineering that Apple put into the iMac, but on the other hand, I did just have the original HD die on me. Recognizing that this could have happened for a myriad of reasons unconnected to CPU temps, I nevertheless wonder about the correlation between HD health and CPU temp.

I am getting very slow UI response in Lion. (iMac 27", 3 GHz, dual core i5 processor, 8 GB ram, 250 GB free on HD). SmartReporter says disk is operating in spec (ie no alarms). Opening disk folder takes 5 seconds to get a spinning beach ball, with another 5 or more seconds to get the folder open. Also slow on directory scan during file opening dialogs. Even get the delay when opening USB drives.
OS 10.7.3, with Apache running, and the usual load of extensions operating. But what I find irritating is that Activity Monitor reports CPU at 25 %, HD occassionally spiking to 100%, but not often, and still I seem to get these unexplained delays. Not fun. Turned off 'disk sleep' in energy saver preferences. Seemed to help for a while. Now not. Reinstalled OS X twice from store and with a USB download stick. Get wierd errors on Console: "5/6/12 5:20:31.000 PM kernel: IOSurface: buffer allocation size is zero".
Killing Safari/Flash via Activity Monitor makes a small amount of speed difference, but not much.Any comments? Suggestions? Is this a general issue with Lion? Are there any profiling S/W diagnostics that might suggest where the processor is spending its time?

From time to time, as I am composing a message using Gmail in Safari, the email screen "freezes." I cannot continue to type, copy or paste, or do anything else to manipulate the screen; it is as if the page has become an image. I speculate that this is due to some inadvertant "gesture" on my part, as at other times my Safari screen will sometimes zoom in and out unaccountably, presumably because my track pad senses two fingers pinching instead of scrolling. This latter problem is very annoying, but I attribute it to my own clumsiness. The former problem of the screen freeze is more than annoying, as it requires me to completely redo a sometimes lengthy email. Is there a gesture that causes a screen to be captured as an image?
I have an older mac with snow leopard and I just bought a new AIR with Lion. Is there a way to transfer everything including programs that are work related on to the new machine? Can I do it with time machine?
Ever since I upgraded my Macbook Pro (mid 2009) dual core from Snow Leopard to Lion, the start up time has increased significantly, and the battery life seems to be lower than it has ever been. It has been several months since I upgraded so indexing is not an issue. What should I do, and how can I get back my missing battery life that Lion took away? And how can I make my reboot and startup time faster.
I have downloaded Lion OS 10.7.XX trhough App Store. When I tried re installing the OS it failed after the bootup due to the Hard drive error. Now it is recommending me to format the Harddrive then re install the OS. I'd like to go back to my previous us so that I back up my data prior to formatting the hard drive. How can I boot from my previos operating system that was installed on the device?
my system preferences froze on me a couple weeks ago while i was trying to change my screen saver. i've forced quit the program and computer, but when i boot back up, and reopen system preferences it opens up where it froze in the backgrounds settings. yesterday i shot down to see my buddy at future shop and he tried a few things and nothing changed. he called apple and they said this issue has come up a few times now. they recomended to delete a few uneeded files in the program or reinstalling the operating system. we deleted the files and nothing happened. so he told me how to reinstall the OS. i said goodbye because he left for cuba today. now i have time to do the reinstall and dont remember how he said to do this.
I just picked up a Powermac G5, 2.3 Ghz. model and was wondering if it supports the newer Apple operating systems? I believe it has 10.4 installed right now but would like something a little more updated if possible.
Super slow FCP 7.0.3 on an iMac ( 3.4 GHz Intel Core i7, 4 GB 1333 MHz DDR3). The system seems to freeze up constantly when scrubbing through/playing/editing clips. Is there a better operating system to use FCP7 with than Mountain Lion?

Is there a way to make Mail show messages from the Trash when "include related messages" is turned on? If I have trashed a message and receive a later reply from that conversation, Mail won't show me the previous message.
i mean seriously, if they are going to put notes, reminders, and imessage they might as well put i books on their, what if someone doesnt have an ipad and wants a textbook on their laptop for a class? or if they just dont have an ipad..
Can I install Snow Leopard while still having Lion on my Macbook Pro? I have some software that will only run on Snow Leopard but my mac came with Lion. I have a Snow Leopard install disc so was wondering if I could run both operating systems...

i need to install windows operating system on my apple as the programs i require for work only work on windows and i was wondering should i get windows 7 or wait until windows 8 comes out not sure whats the best thing to do other options was to buy a cheaper laptop but i wont really use the mac then if i do
In these days it's very hot here, 32� (90F) and over, and my room is exposed at sunlight all the afternoon, and its not very big.
I hold the window closed, but its always hot in the house, 26� (79F) or more.
If I hold the iMac turn on (with minimum brightness) for 10 or more minutes he starts to be heated, and now for example, that is night and I've 24�(75F) in my room, I've these temperatures:
I'm using iStat Pro and I'm just wondering what "too hot" is as far as temperatures go, specifically CPU, HD? I play CS Source and Warcraft 3 occasionally and it tends to get very hot. Up to about 176 degrees F.
I'm buying a brand new hardrive for my 13inch macbook, but need to know the best way to move data from my old drive including the operating system Lion
I bought my first Mac a few weeks ago and so far I'm very happy with my decision to switch from Windows to Apple. But there is one thing that worries me..the temperatures. Here's a screenshot from istat pro. Are these temperatures normal (especially the temperature of the power supply)?
My 2009 13" Unibody MBP will overheat if I so much as look at it, or so it seems!. The issue here is that the fan will come on really loudly and the bottom of the machine will become unbearably hot under the following conditions:
1. CPU load = 20%, temp = 76 C, browsing the web
2. CPU load = 33%, temp = 77 C, watching an online video
3. CPU load = 35%, temp = 82 C, watching a movie on lovefilm
3. The lid of the laptop is closed, and I am carrying it in a bag
4. I am charging it with the lid closed.
5. Using an external monitor I have to keep the lid open and on battery use, otherwise it overheats and the fan come on loudly. Obviously if I shut it down there is no fan noise, however it still gets hot when charging.
Lately I've been feeling my 24" Alu-iMac (Prev. Gen 3.06) and it's feeling really hot. I got iStats and here are my temperatures:
CPU A: 108 F Airport: 140 F Ambient: 75 F GPU: 122 F GPU Diode: 131 F GPU Heatsink: 122 F HD Bay 1: 136 F Memory Controller: 117 F Optical Drive: 120 F Power Supply: 165 F Macintosh HD: 135 F
I have an octo 2.8 which I use at 3.2 overclocked, and I have been running handbrake for 20 hours straight, utilizing all 8 cores. So the machine has been working full capacity for 20 hours, and I check CPU temperatures with Hardware Monitor, and they are 55 degrees. These CPU's are ok up to 100 degrees or so. So how can they stay that cool even at full load? I wish I could overclock them even further but RAM's can't be overclocked further so I need to stop at 3.2 Ghz.
I've recently uninstalled Fan Control and smcFanControl from my Macbook Pro, after trying them for a minute or two. I reset my SMC by using the method on Apples website (Clicking Shift-CTRL-Option-Power Button at the same time). It haven't worked it seem, as I have tried running some games and even at 85-90C degree, its not increasing its RPM. I don't wanna go any higher as I don't wanna risk the CPU overheating.
