MacBook Air :: Fans Run Even When Cpu Temp Has Lowered To 50C?

Apr 2, 2008

using Ichat the other day running a full screen chat, and I saw the temp of the CPU rise to about 65C and the fans started spinning up 6200.... That was understandable as the CPU was under load... but after I closed the ichat down, the CPU temp dropped down to about 50C but the fans stayed at 6200 for a long period of time. probably about 10 minutes or so... then they slowly crepted down to 2500.

MacBook :: Finding Maximum CPU Temp - How Many Fans Necessary

Jul 24, 2009

I have a fan utility that lists 2 fans. The "Left" fan is at 6204 rpm's, temp 81.4C The "Right" fan shows 0rpm's, temp -1C. Is this merely because the sensor is capable of recording two fan speeds or do I really have one malfunctioning fan? (which would explain the high cpu temp, if it applies).

A third sensor, a widget, records the same temp, with Heatsink A 70C and Heatsink B 64C. I realize all three sensors are getting their readings from the same spot; which one do I rely on?

MacBook :: Temp Go Up Absurdly While Running VisualHub / Fans Run Over 6000 Rpm And CPU Hit 92c

May 21, 2009

So I know there are a few other discussions regarding this subject but none of them are providing me with the info I'm looking for. I am looking to get a few responses on other MacBook Unibody's (Pros welcome too) temperatures when running intense programs (games, video conversion, etc.).

So here's why I am concerned. When running VisualHub in particular, my fans and temp go up absurdly. According to iStat, my fans are over 6000 rpm and my CPU temp hit 92c the other day. I shut it down bc I was having visions of my MB melting in front of me. I have even gone as far as propping up the back to allow for more air flow but that hasn't made any difference as long as I use pretty much any video conversion apps. Games (like Spore) make it hot, but not like this

I can find links to the previous MacBooks temps (which I had and this was never a problem) but nothing on the Unibody's. So please everyone, do share. Please include what apps you were running or if your MB's ever shut down from overheating.

MacBook Pro :: Won't Install Firmware Update / Can't Work With Fans And Temp

Feb 8, 2010

I'm nervous to install the Firmware update 1.3. As I've heard from a lot of people the update has crashed their mac. I know it has to do with the fans and temp. My Mac book pro is running at 135 F at 2000rpm is this ok? Is it too overheated. Should I install the firmware I'm so nervous to install it just in case it breaks. Here's the rest of my specs...

Model Name:MacBook Pro

Mac :: Constant CPU Usage & High Fans Speed Temp On Black Santa Rosa MacBook

Mar 11, 2010

I only started noticing my fan running a bit on the fast side this evening after installing the new Safari 4.0.5 update. I looked at iStat Menus for temp and CPU. And I was seeing about 190 degrees F for CPU temp with lid closed running ext display. Also there was a constant usage of the cpu (about 30% User and 20% System). There's not one particular process I can see in Activity Monitor that acting out of the ordinary and using a lot of CPU. Just stuff like coreservicesd, WindowServer, launchd that are shuffling around and using about 1-4% of CPU.I ran repair disk permissions and verify disk. Verify Disk found errors and said I need to repair my Macintosh HD, which I have now done successfully.

IMac :: Controlling Max Temp Of Fans / Booting From External HDD

Nov 20, 2010

I have a 2007 Intel 24" iMac (Last of the white plastic editions) and I've recently had troubles with the 7600GT Graphics card. The computer would get strange artifacts all over the screen, before crashing. Unfortunately, it is out of Applecare, so I took it into a shop and had the card replaced. Upon receiving it back, they told me that they replaced the graphics card, but still found problems with it booting up inconsistently. After some testing, they realised it was the Hard Drive controller at fault, and put my harddrive in an external USB enclosure and booted it off that instead. This was an easier solution than replacing the entire logic board, they told me. (and they gave me the enclosure for free).

Now I've brought it home, and set it all up, only to find that the HDD fans are constantly spinning at 5600 RPM, which is deafeningly loud, even so over my room fan. I presume this is because there is no longer any hard drive controller/hard drive in there. I've installed SMC Fan Control, but to my dismay you can only set the minimum fan speed, and not the max. If possible, i'd like to set the max fan speed at a much lower rate, without needing to open up the iMac. So my questions are:
Is there a way I can set the max fanspeed for the HDD, or disable it since there isn't one in there anyway? And is there a better solution for booting my iMac OS onto an external HDD? (i.e. Should I look into buying a firewire 800 drive enclosure instead of this USB 2.0 one?)

IMac (Intel) :: Installed SSD / Constant Fans / No HDD Temp Sensor

Dec 10, 2014

I've recently installed a Crucial M500 512 GB SSD into my 21.5" 2011 iMac. I've done this to quite a few iMacs, and am well aware that some have a temperature sensor on the factory-installed hard drive. This one, however, did not, and now that the SSD is installed, I'm getting constantly running fans. 

The fans run whether it's booted from the internal SSD, an external FireWire HD, or even if it's sitting in Target Disk Mode or on the Boot Options screen, so I feel like it's hardware-related.

MacBook Pro :: Won't Work With CPU Temp / Sending Warning For High Temp

Mar 19, 2010

I downloaded a program to monitor my late 2008 unibody Macbook Pro's temperatures. Just a few minutes ago while playing music/playing an ONLINE game real briefly it warned me that my CPU temperature was too high. (167˚ F) Is that too high of a temperature? What should the "range" be?

MacBook Pro :: Won't Work With Temp / Temp Rise After 10.6.3

Apr 6, 2010

I have a MacBookPro5,4 2.53GHz with one fan and only the 9400M. After updating to 10.6.3 the operating temperature seems to have risen from about 43 degrees C to about 48. It has been getting warmer here in Japan so the ambient temperature is different but I still think this rise in temp. is due to the update. I have smcfancontrol installed and set to 2500rpm instead of the normal 2000, but it seems to be not enough to keep the temp. under control, as it did before the update. Any relatively hard use of the cpu and the temp goes up to 60 degrees.

OS X :: Unable To Work With CPU Temp / Can't Control Temp

Nov 1, 2009

I was just adding some Quicklook plugins when my temps started to soar. I have restarted, repaired permissions, removed said plugins, and tried other accounts. Nothing is lowering the temps. Weird thing is is Activity Monitor is showing NOTHING using the processor nearly enough to jump my temps to 85 C with nothing running.

I'm "controlling" the issue for now by ramping my fans to full speed. Even with this I am hovering around 70 C...a good 10-15 C above what I am normally at (and was at 30 minutes ago).
*Note: Normally running fans at 6000rpm would give me temps in the mid to low 40 C range

MacBook Pro :: Fans Suddenly Making Wierd Noises / Fans Are Hitting Something?

Jul 27, 2009

the other day i wake up and open my macbook pro and immediately heard the fan making noises ive never heard it make before. i checked istat pro. the fans were going at 2000rpm. this is when i started to get concerned since i would never hear the fans at that speed before. the difference was day and night. it sounds like the one or both of the fans are hitting something. i always hear the noise when i start up or wake up from sleep and after a while (30 minutes to an hour) it usually goes away but has come back once without me turning off or putting the computer to sleep. its a refurbished less than a little more than a month ago. im hoping its just some dirt that made it through keyboard and will eventually go away because i dont want to send my machine in to get manhandled by apple repair. has anyone had something like this happen before?

MacBook Pro :: Won't Work With Temp / 165+ F

Sep 14, 2009

I just started using the aluminum MBP 15" and used to have 13 Macbook aluminum. and as far as i can tell the 13" did not get as hot as my 15" I just installed a fan and temp controller and even with running the fan higher then default os 10.6 temps reached 165 F I freaked out and cranked up the fan to 5000 RPM and temps dropped so far. So, How hot are these MBP supposed to get until it no longer safe?? And its not even close to being where the MBP is: sitting in my office on a desk where its cold and i have to drink tea to stay warm.

MacBook Air :: Wants To Know Heat Sink Temp?

Apr 23, 2008

What is your heat sink temp when the cpu is running hot, like 90+ degree C?

I recently performed the excess thermal compound removal procedure. Now I am worried that my cpu and heat sink are not in 100% contact, due to the very small amount of paste applied.

My heat sink sits at around 50C under normal load (cpu temp ~ 60). But at high load, cpu up at 90+ C, my heat sink is still at around 50-60C. Is this normal?

MacBook Pro :: Getting High Temp In 90s Playing SC2

Aug 3, 2010

I don't see anyone else mentioning temps this high. My specs are below. I followed the directions in a post here in the forums and his directions did work, and I used the modified latest drivers from laptoptogo (258.96), and I was able to overclock the gpu on the windows side. I'm using Vista 32-bit (I know, but that's the only Windows OS I have). I didn't even OC it much, just 550 on the core and 1200 memory, and all was well. The framerate noticeably improved and I was able to play SC2 on mostly high settings (including shaders) with FPS ~ mid 30s and lowest mid 20s. I was a happy camper until I checked my temp via the Nvidia monitor, and noticed it went up to 92C at one point! At first, I thought this was because I was playing on 1080p on my HDTV, but I played again and it went to 88C on native screen.

A couple notes: I did not modify fan speed (allowing the native algorithm to run). I have a Core i5 15-inch MBP, 2.4GHz, high-res matte screen, 320 GB HDD, Vista 32-bit under bootcamp. Playing in native res. How come my temps are running so high? I know YMMV but I haven't even OC'ed it half of what people on this forum are doing successfully with stable temps in the 70s. Also, could it possibly be the fact that I'm using the latest drivers and maybe I need to use the older driver people are mentioning on this site? Is it possible I need to monitor my temps with another program other than the Nvidia one?

MacBook Air :: CoolBook Temp 92 Degrees Celsius

Oct 26, 2008

I run 2 instances of yes > /dev/null in the terminal windows and the coolbook temperature rises to 100 degrees Celsius. In istat pro its 105 degrees Celsius for the cpu? And of course its downclocking to 1200mhz. If I use the lowest voltage in coolbook the temperature will reach 92 degrees celcius, still really high. I'm only stressing the CPU, wonder what happens when I also stress the GPU. It seems the air is really not capable of this 'high-end' processor and gpu, I wonder if the rev2 of the air will be any better.

MacBook Pro :: Won't Work With CPU Temp 100C / Fan Still At 2000RPM

Mar 14, 2010

I've notices a really strange behaviour with my 13" MBP. The fan simply doesn't go faster on high loads, which results in a CPU temperature that is far beyond the operation specification Intel provides.

Seems as if the SMC controller is kind of broken. I tried to reset it, but that didn't change anything. A PRAM reset also didn't work.

MacBook Pro :: Proc Temp Constantly High - How To Know About It

Apr 7, 2010

I had my computer idling and noticed that the fans sped up to full blast, so naturally I tried to figure out what was causing it to heat up. I quit pretty much every app I had running, no diff. I unplugged my iPhone, no diff. Even shutdown the computer, fans went right back up as soon as I loaded up OS X. So I looked at SMC Fancontrol (which I never really even use) and the temp was at 88 C!!

I have nothing open, completely turned off the computer and rebooted it to make sure that nothing running would be causing it, and it's STILL running hot as hell! Is there anything I can do to see what's causing it to run so damn hot? I really don't wanna put a crap-load of wear on my fans and CPU here.

I'm using a 2.2 ghz SantaRosa MBP running the latest version of Snow Leopard.
