Fans Never Spin Any Faster IMac Overheating?

Mar 30, 2012

I have brought a new iMac 27'' the i5 model. I have noticed that the fans never change speed no matter how hot my processor gets ? Is this normal ? I have ran prime 95 and istat pro to check the temps and fan speeds. Nothing changes apart from the temperature.

Info:
iMac, Mac OS X (10.7.3)

MacBook :: Fans Run Very Fast / Computer Became Cooler Than Before

Aug 3, 2009

Anyone here know if the fans run less now? My Macbook 2.2Ghz fans run a lot and this things HOT a lot of times. Have the computers become cooler running now vs. then? I am interesting in upgrading, but my main concern is the heat. I just don't enjoy a private space heater here in the desert...

PowerPC :: IMac G5 Failing To Boot Up - Fans Whirring Fast

Dec 16, 2008

Originally my iMac G5 (1.6 GHz 17 inch) was failing to boot up. It would get to the grey screen and the apple and it would just stay there and pretend to be a rocket ship with it's little fan whirring as fast as it could after five minutes. So I reset the SMU, fan stopped, still wouldn't boot. Booted it off the 10.5 install cd (which it was running fine until it wouldn't start up). It wouldn't see the Macintosh HD for a while unless you went to disc utility > partitions and changed it from current to one and instead of applying just let it sit there before switching it back to current. Took about 10 minutes of sitting there.

I did disk repair said there was no problem. Disk permission repair said there was a few problems and said it repaired them. To be safe I backed everything up using target disk mode (where the fan tried to play rocket again even though I reset the SMU), erased my hard drive and reinstalled. Now it shuts down randomly when it goes idle, and takes 10 minutes to start up past loading the dock to load the apple bar Mac HD icon and whatever is on the desktop (which is a single empty folder).

MacBook Pro :: Fans Never Spin Up?

Jun 17, 2012

I noticed that on my macbook pro retina, i never heard the fans spin up. 

I tried Prime95 to stress the CPU, temperature went up to 98°c and the fans stayed at about 2000rpm...  I immediately stopped to avoid damages.

MacBook Pro :: Fans Never Spin Up While Under Stress

Dec 2, 2010

I was noticing a lot of slow-down while playing computer games on my MBP. My computer far exceeds the minimum requirements for everything, so I reckoned it must have been something other than a slow processor (2.53 GHz Core 2 Duo), low ram (4 GB) or a completely inadequate graphics card (Nvidia 9400M). The games range from 'Day of Defeat: Source' to the 8 year-old 'Return to Castle Wolfenstein'. After a bit of research, I came to realise that my exhaust fan is never speeding up past 2005 RPM no matter WHAT the load on the CPU is. To test this, I downloaded smcFanControl and ran CPUTest. As the CPU went from 50*C to 95*C, there was hardly any change in the fan's speed. The variation went between 1995 and 2005 RPM.

In order to keep the computer relatively cool when playing games or doing anything that is CPU-heavy, I have to manually increase the fan's RPM in smcFanControl. I find that setting the fans to the maximum, 6000 RPM, keeps the computer cool enough to process these games. This program works wonders and I've not had any slow-down in games as a result. However, I am worried that there might be something wrong with my Mac. Why does it not automatically increase fan speed when reaching higher temperatures? I've even reset my SMC (SHIFT-CONTROL-OPTION-Power) on start-up just to be sure I've tried everything. Any suggestions as to why my fan seems stuck at 2000 RPM?

MacBook :: System Will Not Power On But Fans Spin

Aug 17, 2009

I got a new macbook black that is not covered under warranty, the magsafe fried on it and it used to boot up but not charge the battery or show any signs of power from the magsafe so then I bought a new magsafe that connects to the logic board and replaced it and when I plugged the power adapter in it tried to turn on right away and then the fan spinned and the sleep light light up then it shut off right away and I didn't smell nothing from the macbook or logic board. The battery now charges and the light on the magsafe adapter lights up so I tried to turn it back on and it doesn't the same thing turns on and then right off just the fan spins and then the hdds spin lasts for like a sec or two. I tried to turn it on with the battery out and with just the battery in nothing swapped the RAM same thing went from two 1 gig sticks to 2 256mb sticks and then tried another two 2gig sticks same thing then I tried a different hdd and have the same thing happen? What I need to do to get this working and yes I tried a google search and every1 ended up taking it to apple and I cannot do that.

Software :: G5 Will Not Sleep / Shutdown - Fans Spin Up

Sep 10, 2009

I have a G5 that is about 5 years old. For some reason it will not sleep or shutdown. When I try to do either one of those actions it does simi-sleep/shut down, but not completely. By that I mean it sounds like the hard drive spins down but then fans still are running. After about two minutes the fans spin way up and the Mac won't start back up. I have to pull the power on my battery backup. I took it to the shop (Not an apple store) and they reinstalled the OS for me and put some new ram in. Supposedly they "Fixed' the problem.

MacBook :: Overheating / Shutting Down - Force Fans To Spin?

Sep 7, 2010

Over the past few weeks my blackbook has been shutting down more and more frequently from what I can only believe is overheating. I just checked my computer upon startup with SMC fan control - it starts up at about 70 C and at about 3500 RPM. Yet, after a few minutes, the fan immediately drops down to 1100 RPM or and fluctuates between 800-1400. I try to force the fans to spin with SMC Fan control, but nothing happens. I've looked all over the web and I can't find anything definitive. I know that macbooks tend to overheat. What can I do? I'm at college and I really need to find a fix for this as soon as possible.

PowerPC :: Fans Rev Very Fast At Boot / G4 MDD

Apr 26, 2009

I just picked up a G4 MDD off ebay. Everything seems to be working fine, and it passed tech tools tests for whatever that is worth. The only thing I noticed is that for about 2 or 3 seconds during boot the fans seem to rev up pretty high, then settle back to normal. Does anyone else with this computer have this issue or has anyone heard of it?

PowerPC :: G5 Pro Fans Running Too Fast

Jul 28, 2009

The fans on my G5 Pro are running at close to 3000rpm most of the time. I have read other forums and do not think this is normal at all. I started looking into the fans because I am getting frequent kernel panics (black screen crashes) and thought it might be the machine over heating. My CPUs are at about 50C to 52C and the fans are constantly running that fast.

MacBook :: Fans Spinning Fast And Non Stop

Jul 31, 2009

For the last couple of days my fans have been going crazy, spinning at 6200RPM non stop. I installed fan control last month but the issues just started. When I open up fan control it says my fan should be spinning at 4000RPM. I had smcFanControl installed before and its still installed. My bluetooth module over heated yesterday so I used SMC to rev up the fans. I don't know if that is the issue because it isn't running now. I'll try uninstalling that now.

Mac Pro :: Fans Revs Very Fast / ATI Radeon HD 4870

Apr 10, 2010

So, I got a flashed ATI Radeon HD 4870 off eBay. It's running fine, but it revs for every little thing I do. Every time I scroll on a webpage...It's revving for every letter I type. The faster I type, the louder it gets. If I watch a video, it runs at high speed. The X1900 XT was quiet compared to this thing.It's like it's set to run the fan as high as it can for every little thing that happens. What do I do?

I also just tested it in WoW, and it was getting about 12FPS in Shattrath at full graphics. I think I remember my x1900 getting the same, if not better. Something's gotta be wrong. Now it's just constantly running its fans, and I'm not even doing anything. I'm on my Macbook. My Mac Pro is just sitting there, nothing but the Finder.I'm also not happy with the speed it renders video compared to my dinosaur x1900 XT. Not worth the upgrade. Could the ROM they flashed it with be bad?

PowerPC :: G5 Won't Wake From Sleep - Fans Go Insanely Fast

Jul 13, 2010

This problem just started happening on my 2005 Power Mac G5 Dual 2.3Ghz Processors.

I activate sleep, and it refuses to wake up again. Then after a few minutes the fans slowly increase in speed until the computer begins to sound like an aeroplane taking off, at which point I'm forced to perform a forced shutdown.

I've resetted the PMU and it doesn't seem to have worked. It is fully up-to-date in Software Update and is running the latest version of OS X Leopard.

Mac Pro :: Fans Running Fast At Idle / Little Gap Between Closed Door And Outer Case

May 7, 2008

just received my new MP and noticed the same thing with the 08 Modell which is that the door sits slightly offset on the case meaning theres a little gap about 0,5mm between the closed door and the outer case.

Second my fans "boostA & boostB" are spinning at 1100rpm at idle I thought they should normally idle at around 800rpm? (I read at least)

OS X :: Computer Gets Hot And Fan Doesn't Spin Over 2000rpm

Jul 31, 2009

My computer stays at about 40C normally but when I watch videos or dvds my computer gets as hot as 81C but the fan is still at 2000 rpm. If my fan spun faster it should dissipate the heat more right? Is my fan supposed to spin faster? btw I put my umbp (mid 09 2.53ghz) on a fan cooler by antec.

OS X :: Computer Slows Down When External Disks Spin Up?

Apr 2, 2009

I have had this issue for years now on all my Macs.

It happens to me with my current iMac intel, which has 2 firewire drives connected to it (one 800 and one 400).

When the firewire drives randomly spin it, it sometimes makes my iMac stall a bit. Like the beach-ball will sometimes even come up, but otherwise it just like it freezes a split second while it's bringing the hard drive back up the speed.

Why does it do that, and is there anyway around it?

It makes using an external drive frustrating and hurts the beautiful mac experience.

I have 4GB of memory, very fast computer otherwise, so it's not that.

IMac :: How To Spin-up Of External FireWire Hdd

May 6, 2009

I have some iMacs (running 10.5.6) each with an external direct-connect FireWire hard drive. About every ten minutes, these drives will spin up for a minute or two, then spin down again.

Background: The drives are set as Time Machine backup volumes on their respective iMacs. I assume the frequent accesses I observer are not related to Time Machine (because the accesses are much more frequent than the hourly backup schedule). The drives are not remote-mounted anywhere.

OS X :: How To Make Computer Run Fast?

Jul 12, 2009

alright... i got my MB in october 2007, and it ran great for about a year and half, but just recently, its been dogging and lagging so much, its bugging the crap out of me to the point where i borrowed my friends external HD and put all my important stuff on there, and erased and reinstalled mac OSX on there, and it still behaves the same way. my specs are in my signature so let me explain...

ill be running just itunes, ichat, and safari watching youtube videos or something, and the youtube vids just start skipping, and then the sound gets all distorted like it sounds like its underwater gargling. then i shut the macbook, reopen it, and its fine for about 2 or so minutes and then it does it again. or ill be listening to music via itunes, and reading some forums or the news or something, and when i scroll down, the music skips. its really annoying. i rarely get beach balling, but safari, or firefox, or itunes takes an eternity to load. and my fan allways seems like its on, and running hot as hell.

cpu user runs about 63% to 70% all the time
system about 15%

memory: active- .98 gb to 1gb
wired: 319 mb

temps: allways around 150 F or a little higher.

fans exaust- 6192 rpm

MacBook Pro :: Fast New Computer For Photographer?

Jan 26, 2010

My cousin is a photographer, and she wants to change her computer from a PC to a Mac. She asked me to help her select one of the laptops. Basically, at most, she would have 3, 21MP photos on Photoshop, doing whatever photographers do. Which laptop would be good for this? I was thinking with going with the low-end of 15", and add 8G of RAM to it. But would the 13" with 8G of RAM suffice as well? Or should we go for something faster?

OS X Yosemite :: New MBA - Computer Clock 5 Minutes Fast?

Dec 12, 2014

i bought my new MacBook Air last week and unboxed it today.

First problem I noted is that the clock time is 5 minutes fast. I don't know why.

I clicked "Set date and time automatically" (tried different servers), as well as having clicked "Set time zone automatically using current location". Still, the clock is precisely 5 minutes fast than it should be. The laptop IS connected to the internet and I have re-started it a couple of times. Still, 5 minutes fast.

Why is that the case? And how can it be resolved? (I would prefer not to manually reset the time).

(I am not transferring any files to this computer until the time issue is resolved because of concerns over time stamp).

Info:
MacBook Air (13-inch, Early 2014), OS X Yosemite (10.10)
