MacBook Pro :: Did Istat Crash The Internal Fan Speed Control
May 10, 2010
got a problem, after i bought the new macbook pro 13'':
i noticed that the fan speed is always about 2000rpm... doesn't matter, whether the temperature is at 40�C or at 70�C or 80�C (my mbp doesn't get hotter)... always same rpm.
is that normal? additional info: i downloaded istat menus 3 which has the option to control the fan speed (i deactivated it... no changing... always 2000rpm). did istat crash the internal fan speed control?

When I run SMC my fans kick to 4000rpm and SMC shows that my default speed is 4000rpm, I cannot put it lower then 4000 only higher. I have tried uninstalling the program and reinstalling.

What's up with this in the newest version of SMC that just came out today? The min now goes below the original 2500 RPM that the Apple engineer's decided on??

I installed (and subsequently uninstalled) two different fan control programs... Since then, my fan speed has increased somewhat dramatically. Instead of the normal 2000 rpm (approx), it now runs at 3500 to 4500 rpm with CPU temps between 55 & 65 deg. C. I'm wondering if one of the programs modified some fan setting and how I can restore the factory defaults. I'm on a Macbook Pro OSX 10.6.8 *additional note: I only have one fan running (left fan), which is why I downloaded the fan control programs in the first place... but the left fan was running at around 2000 rpm even though it was the only fan (until I installed those programs)
Info:
MacBook Pro, Mac OS X (10.6.8)

I have an iMac 9, 1 (the '09 model). 3.06 GHz DC. So I tweaked the fan speed a little to see how cool it can get, but, there's one tiny problem. I used "smcfancontrol_2_1", I can get the speeds up, but not down.

When I have no other internal drives connected I have no problems with Windows 7 loaded in boot camp. But when I connect my other 4 internal drives (in bay 2, 3, 4 and optical bay 6) which are set up as a Raid 0 configuration for Snow leopard I run into problems- I get a blue screen of death almost instantly when I start to move the cursor in windows 7. Seems like if there was a way to tell Windows 7 to ignore the 4 other drives then it would work fine? I don't want to have to pull them from the machine each time I start in windows 7.

i am new to mac and coming from linux. got my mac pro about 3 weeks ago and i am wondering if there is something similar to powernowd or cpufreqd under osx to control the cpu speed and voltage of the 8 core monster. i mean there must be some power saving features in osx for the macbook series i guess and i want to know if there is something similar for the pro series.i am not sure if i better asked this questions in the osx forum but its somehow mac pro related. so are there any power saving features cpu speed or vcore related for the desktop mac series in osx right now?or is it maybe not supported yet because the hardware is so new?

During the summer, I don't have A/C in my house. My temps were getting pretty high, around 55C/130F for processors and up to 78c/172f for ram. That is pretty high, and I suspect it is because the ambient temp in my room is somewhere in the 90s. I am just very acclimated to the heat, and it doesn't bother me.
I downloaded SMC Fan control and bumped the min fan speeds up to:
1250rpm for Exhaust
1150rpm for CPU
800rpm for Power Supply
1350rpm for HD
This has made a tremendous difference. CPU is down over 20C and ram is down about 30-35C. Are these fan speeds safe? What are the Mac Pro fans rated at, and will the increased speed shorten their lifespan? I'd like to keep these current fan speeds if it is safe.

Just downloaded and installed this app, been using it for a few hours, I am a fan. Just a quick question, it won't seem to let me set the minimum fan speed below 2000rpm (the standard level for the app), is this normal, I thought I remembered the apple default being lower?

I have a slight problem with my volume controls on a Macbook Pro. They're not doing exactly what I want them to. I have an external sound card and by selecting it as my default audio device the macbook pros own volume control gets locked and there's no way to adjust it. This means that it renders the keyboard and Remote control volume buttons useless and I still have to run across the room to adjust the volume on my audio device when I'm watching a movie through the tv away from the macbook. Is there no way to enable this function anyway so both controls work?

Set the computer to output to speakers, keyboard vol controls etc control the speaker sounds and "pop" out of the speakers.
Sleep the system and it reverts back to the internal speaker, even tho the output from iTunes, Quicktime or whatever comes out of the speakers.
Does this happen to anybody else?

Does the base speed mean the minimum speed for the fans to run at? Or, is the speed the fans will run at all the time?

Just a strange occurrence this evening: I just watched a DVD on superdrive: when it finished, I ejected it and glanced at my Finder menu bar. IStat Menus gave me a temp of 135 and rising (went as high as 140 degrees a few minutes after ejecting and shutting down DVD Player). But the fans aren't on at all--never came on, as far as I can tell--and the MBA feels cool to the touch. Now it's maybe 20 minutes later and iStat reads temps as still at 115 degrees. But my laptop feels totally cool to the touch. I restarted, hoping to reset iStat, but no change. Any idea as to what's going on?

So apparently every time I restart, iStat pops up annoyingly and tells me its now a paid program, and I don't want to pay for it. Are there any alternatives to see my CPU speeds and temperatures, also my memory usage in the top bar? I want something that I can always see.

Sorry for the title but I couldn't think of anything better. Hopefully I'll be able to explain my problem. I have a MPR 2.53 ghz, 4 gig ram, I'm using Safari 4.04. I am using the WIFI at a guesthouse in Thailand (but I had the same issue in China, Vietnam ...). I ran a speed test and it said download 7mb/sec and upload about 1mb/sec. I have an "app" that says bandwidth in 1.3kb/sec out 1.0kbs. I thought maybe it was Safari so I downloaded and installed Firefox. firefox gives me similar speeds. When I downloaded Firefox though I had a download speed of over 1mb/sec. But as soon as it finished downloading the speed went back to around 1kb/sec. I have rebooted my MBP many times. I did some Google searches but didn't find anything helpful.

Because it happened to me a few times where the cursor will skip or one time the cursor wont even move or be responsive with my finger. The weird part is that once I exit safari the trackpad seems to work again perfectly. Also not sure if its because I have sweaty hands and my fingers are too wet? But its not something excessively sweaty or nasty just a lil moisture I guess on my finger tips at times.
Update: Never mind, found out the culprit istat pro.

I purchased iStat menus for my MBP (no r) mid 2012 and it does not seem to work right. It seems to install ok without any messages popping up but once installed where I get the chosen options onto the menu bar I have a problem. When I click on say CPU or any of the others, a window shows the details but when I then click in that window, at the bottom on EDIT I get a message saying: Tried uninstalling iSta menus and reinstalling but no go.

MacBook Pro, Mac OS X (10.7.4), Mid 2012

I recently purchased a new SSD and would like to input that into my MBP 2012. If I have a partition on my external HDD that contains the carbon copy of my MBP, am I able to clone it into my SSD after I have installed it in the MBP through the USB?
Internal HDD --> External HDD
Place internal HDD into optibay, and place SSD into the harddisk slot
Connect External HDD via USB to MBP
CarbonCopy to new SSD via USB from External HDD
Format Internal HDD
Will this work?

I know iStat doesn't give you gpu core use like it does cpu core/thread use, but is there an app available that does? Bars or something that show the cores' usage?

Does it hurt the computer... If the computer is doing something (watching flash, playing a game) that turns on the fan full speed;Does this hurt the computer? There are a few games I like to play and they turn on the fan at full speed (computer gets hot too, on the bottom.)

I have a 2006 Mac Pro 1,1 with dual Xeon 2.66GHz. One of my favorite apps on my Macs is iStat Menus for which I purchased a family pack. I am running latest version 3. However, when I added it to my Mac Pro I am getting goofy CPU temp readings. At idle I am reading about 60C on one CPU and 55C on the other. But then if I fire up all the cores (Handbrake for example) then the reported CPU temps DROP to about 48C and 43C (notice same differential of 5C between CPUs). All the fan speeds stay the same so it is not extra cooling kicking in. Seems to be reading the wrong thing.
I know with Intel that the CPU just reports the distance to Tjmax and then the software reading that number takes the TjMax reading for that particular CPU model and figures out the corresponding Tj. It almost seems to be what is happening is that iStat is reading the "distance to TjMax" and reporting that without doing the math. That would account for the reading working backwards I suppose.
