MacBook Pro :: Fans Seems To Run Continuously


I have recently noticed that what I believe to be the fans are running all the time. I do not believe this is a function of heat. Restarting doesn't make it go away.

MacBook Pro :: Fans Run Continuously @ 6000rpms?
I just got a new 17" Unibody 2.66 and the fans run continuously at 6000rpm. For example, right now they are running at 6000 w/ temps of:
CPU A - 35
GPU - 36
GPU Diode - 38
GPU Heatsink - 30

This is on a clean install with only Safari running.

What's the deal?

IMac Intel :: Fans Run Continuously At High Speed?
I've got a small issue with my family's iMac that just started this morning. The CPU fan runs at a constant ~4000 RPM, even when the CPU is idle. I've run iStat on it and there are no apps taking any significant percentage of the CPU. I've restarted, and reset the SMC. In both cases the fan will start up again upon reaching the login window.

My question is are there any iMac-specific cures for something like this that have been seen in this forum in the past? I just thought I'd post here in case of something like this before I call Apple and have them replace a faulty temp sensor (probably the most likely cause) under warranty.

MacBook Air :: 2011 Fans Continuously Running (regular Fix Attempts Applied)
I have a users machine that the fans wont stop running at high speed Its a 2011 MBA 13" i5 128gb ssd I installed a few fan monitors and fan controllers, they all say the fan is at 0rpm. Apple is not my first language; but Im warming up?I have performed an SMC reset as well as the P&R? reset?   Both went through properly, the SMC i could see the power cord light change colors, and the other reset performed before the chime would make the chime, black screen, rebooted. Alot of what I read on this topic consists of the machines fans ramping up because they are being used, or if its a fluke the SMC will reset it. I havnt been able to find anything in regards to the computer reporting 0% and just running non stop.

MacBook Pro :: Fans Run At Full Speed While Charging
I've got this weird problem with my late 07 SR 17'' MBP, after I plug in the Magsafe charger the fans start spining and in like 3 minutes they reach 6000 rpm (both of them) and stay that way until it's finishing the charge. I did the same exact tasks with my laptop charged and plugged in, and the fans stay around 2000 rpm, as opposed to when it's charging staying at full speed.

MacBook Pro :: MBP Not Booting, Now Fans Run 6000RPM?
Just been having some pretty big issues with my late 2007 Macbook Pro.Basically, the other day I was playing World of Warcraft, when my Macbook ran out of juice. I plugged in the charger, left it for a few minutes, but no, it wasn't going to wake up again.

So I turned it off, and that was basically it. It wouldn't turn on again, regardless of whether or not the charger was plugged in. Eventually I got it to boot by doing an SMC reset, but now the fans run at 6000RPM and it says it's at 0C and the fans are running at 0RPM.Which is making me believe that the temp sensor is screwed.

Also, it no longer detects my battery, and Windows simply doesn't boot. Mac OS does, but again, I get these issues. System profiler says that my battery has 0 capacity, 0 charge cycles, it is not charging, and it's essentially dead. However, if I unplug the charger, the Macbook continues to stay on, though I can't say how long this is for.

I'd also like to make it clear that the fans start running at this speed from the second it starts up, right before the grey screen appears.I've tried PRAM and SMC resets multiple times with no luck, and I'm wondering if the logic board is just partially fried or something.Hopefully you guys can help me, and no, it's not under warranty, though I do have home insurance which has covered this Macbook before after it got sat on and the screen was crushed.

MacBook Pro :: Fans Run When Computer Heats Up Or At Specific Temperature
I've had my MacBook Pro for about 3 weeks and have noticed that I've never heard fans running. I assume that there are fans, especially in a computer that heats up so easily. Should the fans be running when the computer heats up or are they waiting for a specific temperature?

MacBook Pro :: 2008 MBP Fans Constantly Run At 2000rpm / No Cpu Hoggin Process?
Both my left and right fans are constantly running at 2000 rpm. They have not done this before, but over the last week I have noticed this issue. Heat does not seem to be an issue in triggering the fans. I'm so confused on why they're are constantly on now.No CPU hogging processes or high temperatures.

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

Power Mac G5 :: New Power Supply Now Fans Running Continuously
About a week ago, my G5 went dead - no power at all. An Apple certified tech that I know came to my house yesterday to replace the power supply with one (600W version) that I ordered. That got me up and running, but ever since then, ALL my fans have been running at high speeds nonstop. I looked to see if there is a firmware update and tried resetting the CUDA again - same results. Tried setting processor speed to reduced, even tried it on highest - same result. Only way I can get them to stop is to to the computer to sleep or shut it off. The fans were never like this before.

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

IMac Intel :: Alert Sound Run Continuously - Cursor Flickers
I have an intel IMac 20" running system 10.5.8. I have a problem with the alert sound running continuously. It doesn't do it all the time, but it does seem to always do it when I open system preferences or Logic Pro, and sometimes other applications. Also the cursor flickers on menu items. If I put the computer to sleep and then wake it up it will stop for a while then start again. If I change the alert sound it sounds continuously with the new sound.

I have the late 2008 MacBook 2.0 GHZ C2D.

I finally upgraded to the max 4GB RAM from Crucial:
http://www.crucial.com/store/mpartspecs.aspx?mtbpoid=F5A5E837A5CA7304

Ever since this upgrade, my system seems to be running hotter and the fans kicking on more often. Fans tend to kick on now if I do anything more than web browsing.

MacBook Pro :: Fans Suddenly Making Wierd Noises / Fans Are Hitting Something?
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 :: Temp Go Up Absurdly While Running VisualHub / Fans Run Over 6000 Rpm And CPU Hit 92c
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.

Power Mac G5 :: Will Not Boot - Fans Run High Only?
My back up 1.6 ghz G5 power mac is misbehaving. I moved the system to another room and when I went to boot up, the only response I got was the fans running at normal speed - and then they started to slowly creep up to a very high speed. No hard drive activity, no monitor activity. I swapped out the memory for the original factory mem - same problem - reset the switch... nothing.

PowerPC :: G5 Fans Run Full Speed All The Time?
My step-son works for a company that uses a variety of computers in their test dept. and when they upgraded the test equipment they gave the old stuff to employees.My step-son is a dyed-in-the-wool PC guy who doesn't care for Macs so when he saw a G5 PPC sitting there he took it home and gave it to me.

It's a 2.0 GHz dual-processor with 8x AGP video. I checked it out and the only thing "wrong" with it is that someone has set up the fans, all of them, to run full-speed all the time.First, how did they most likely do that and, second, how can I return the fans to their normal operation. This can't be good for the computer and it's so loud and annoying that I'd rather use my G4.It's a great computer otherwise, I hope they didn't do something permanent that would require a new motherboard, that's not in my budget.

IMac :: Fans Are Dumb, Run When Not Needed, And Don't When Do?
Any tips on how to fix this?Usually, the CPU fan is stuck at 4500RPMs constantly, CPUs 28?? it runs the fan at 5000RPMs.But whenever the CPU is cooking, such as 92?, it won't run at all, but the other two fans will be at full blast.

Any tips on how to fix this? I took the computer to the apple store 3 times for this issue but every time they "could not recreate the issue". The last time the replaced the fans in the computer, but that didn't fix anything.Anything that would point me in the direction of fixing this? It's just melting itself. Alum. iMac.

Power Mac G5 :: Started Up It Could Freeze At Any Time And Then The Fans Would Run Wild?
My G5 Duel 2 ghz June 2004 died. If it started up it could freeze at any time and then the fans would run wild. After much research the outcome was a bad processor or logic board. Because of an error message I got only once in this whole ordeal that mentioned cpu 1 I decided to go the processor route. I thought cpu 1 might be the top one. I got one off of ebay paying close attention to get it from the same machine and the same part number, 630-6611. It works great. I'm now off my Cube and back to my G5. Only problem now is the fans run at almost full speed all the time, Very loud! I think I've heard about a command I can type into the terminal to fix this. Is this true? I know the fans run at full speed when they don't get info from the temp sensors. Can this be fixed?

Power Mac G5 :: Sleeping G5 Often Makes Fans Run Full Blast And Machine Unresponsive
the only thing new lately is that I installed Leopard 10.5.3 on my dual 2.0 GHz G5 tower.

I usually sleep my machine all the time

now it's a crapshoot whenever I sleep it whether or not it will go to sleep normally, or freeze in a state of screenless unresponsiveness with the fans running on full blast with no way to stop except a hard shut down or power kill

other than this the machine is literally working just fine. Never interferes with my work.

I don't know if this is 10.5.3 related or not, but I do wonder.

I started up from an applecare disc and did a full diagnostic and everything checked out

I guess I'll have to test Tiger sometime again but that'll be a pain because I'm already addicted to Leopard

I just hope this old faithful tower isn't going dead on me. and I wish there was some official word if this was just a 10.5 thingy

Power Mac G5 :: Dead - Turns On But No Screen Fans Run Hard Drives Spin Up
I've had my g5 since 05. Ive run it pretty hard since, but have had no issues at all until last december/jan, when openGL just quit working, the thing got real slow, DVD drive quit alltogether, and i had no network...took it to apple, and they told me the logic board went..replaced it, and all was well

So today i wake up, and i go to wake up my G5...and i get..nothing...yea it turns on, but no screen...fans run, hard drives spin up

So i power down, power back up, and i get fans, no chime, and 3 blinking LEDs. ALright, fine, i know that means ram. So i spend the next 20 minutes removing ram, testing it, matching it, testing other ram, etc...

At one point it did boot, when i ran it with 2x512, and i unplugged the DVD drive, but i couldnt get it to come back after that.

Ive tried resetting the SMU/PMU. Dont even bother telling me try open firmware or zap pram, cause i cant get to the open firmware screen.

Now, i am seeing a TON of these posts for G5s. Is apple going to do anything for us? or are we to expect only a few years out of our new machines til they die and we have to buy new ones?

Also, since apple replaced my logic board, does that mean my serial number changed? as far as i know the machine is out of warranty, since they only added a 90 day one on with the new board..and that was replaced last april..

any ideas? i hate PCs and this experience doesn't fill me with confidence in getting a new mac...that is if i could, since i'm flat broke thanks to the economy, with plenty of projects coming up that i need my mac for, but hey, doesn't look like thats going to happen.

When running a lot of different applications (OpenOffice, R64, Microsoft Office, iTunes, etc.) on my MacBook Pro (2.2 GHz Core i7, 8 GB RAM), Finder freezes continuously. Most of the time it'll restart quickly, or in the best cases, it will eventually start working again after a few minutes. This is extremely annoying as I use my computer for work and constantly have to wait in order to access files. I've tried deleting hidden files in directories among other things, but nothing seems to do wonder.

MacBook Pro :: Screen Continuously Flash / Blink On HDTV
Since the day I got my MBP two months ago I have always had it hooked up to a small HP HD monitor via HDMI. The other day I tried hooking it up to my 32 inch HDTV and now I am experiencing a weird problem. The TV and the Mac recognize each other but the screen continues to flash/blink every second (almost like it is loosing conenction). I check the cords and everything is fine which I assumed because everything is fine when I'm connected to the HP monitor.

MacBook Pro :: Read Of Wireless Router - Continuously Disconnect And Reconnect?
I have read of wireless router issues with MBPs. I have the 13in, 2.26, 2GB (upgraded to 4GB) MBP. When I first got my MBP, I was having to continuously disconnect and reconnect to my router. I assumed I was having the same problems as others on this board have noted. Soon after, however, my work laptop (PC) started having connection issues as well and I have to perform the same process on it. disconnect, reconnect via the laptop, and then everything will work fine for anywhere from 10 minutes to a few hours. (Note: on the MBP, things only work fine for 5 mins or so before I have to perform the action again). It seems as though the MBP is more sensitive to the router issues than my PC.

Nonetheless, I am planning to purchase a new wireless router, since mine clearly has issues and it seems to be getting progressively worse. My question: Is there a particular router that seems to work better with MacBook Pros than others? Any that you guys would specifically recommend? (I need it to still work fine with a PC, as well, because of my work laptop)

Or does it default back to stock?I set up my stable steppings and voltages, do I have to run coolbooks each tie I reboot or turn the MBP on? or are the steppings and voltages, once saved once, stored in some low level area and used until changed by me in coolbooks again?
