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.
View 5 RepliesI'm worried about too much heat and wearing out fans in both the card and my Mac.Below are the conditions, but first:
-Is it normal for this kind of card to run ALL the time? How do I know if it's acting correctly?
-Given the heat and fan speed info below, are my Mac and internal drives OK?
-Am I risking any breakdowns? Due to heat or fans running too much... or?
-Do all graphics cards cause the fans to run like this? Is there a cooler card out there?
-Suggestions to lessen the heat effects... or for another alternative?

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)
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?
View 3 Replies View RelatedThis 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.
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).
My PowerMac's (G5 Dual 1.8GHz procs) fans seem to run at a solid 4k rpm's regardless of what I'm doing, even with CPU usage set to low. I've taken the whole machine apart, cleaning it with canned air and such, but the problem just won't leave me be. The air coming out of the machine is ice cold, and the temperature readings I'm getting are about 86 degrees F for the CPU's and 70 for the HDD, so I'm not sure what gives.. Slot and Backside fans are running at 255 rpm, but the others are all 4k.

Powermac G5 early 2005, dual G5 (not dual core).This is at idle:CPU A 60 degree Intake 300rpm Exhaust 300rpmCPU B 63 degrees Intake 1125rpm Exhaust 1100rpm! I have not noticed this before. They usually remain identical.

View 3 Replies View RelatedFor 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.
View 2 Replies View RelatedAnyone 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...
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?
I just started a video chat on Skype and my MacBook fans started going and are now really loud. Just checked my processes and it said this: Fans are currently at 4550rpm but are now much quieter than when I started writing this.

View 1 Replies View RelatedSince I updated to 10.6.6 earlier today I've noticed that the fan in my MBA (13" late-2010 model) is running constantly. This is rare -- I hardly ever hear it. I opened activity monitor and 'System' is using 45% CPU time, and it's pretty constant.
I have absolutely no clue why -- there's nothing in console to suggest it's doing some task, and I can't see any other hints. Apart from the noise and the heat (though don't get me wrong -- compared to my old MBP it's not really noisy or hot, but I liked it better when it was totally quiet and cold), it's also killing the battery -- 25% has gone in less than an hour.
My OWC RAM is working just fine, but I am growing increasingly concerned about the temperatures at which it runs. I have the 3.0 (120W) MacBook 2008 with 18 Gb RAM (4x4Gb + 2x1Gb apple stock). The RAM in memory module A2 & B2 is getting up to 80 Celsius without even much of a workout on the RAM. What's more, the MacPro fans are not increasing - right now the hottest module is at 76 Celsius and fans haven't increased at all (see screenshot below).
I have installed SMC fan control, which I understand is supposed to set the minimum fan speed, which I have set at 730 because my RAM was running hot even without any workout. How concerned should I be about this? Is this a) a defect in my mac pro b) a design flaw c) a problem with OWC memory, or d) is everything OK and I'm making a mountain out of a molehill?
Well my MacPro 2009 has this weird error where the fans will kick in and a restart wont restore them to normal a sleep cycle will though. It seems to only happen with OpenCL intensive apps but not Cuda intensive apps?? this may be random coincidence.

So I just bought a new Macbook Pro in September (MPB 15.4" CTO: 2.2Ghz Qaud-core i7 processor, 8gb 1333MHz DDR3 SDRAM, 128GB SSD). This was my first apple laptop, and I was just amazed at how quick, smooth, and fluid everything was running (internet, apps, etc.). I ended up installing a few applications from the apple store, installing microsoft office, and partitioning my computer to use Windows 7 through bootcamp (for those windows-specific applications). I'm a student, but take all of my notes by hand; I bring my computer to class with me anyway. When I get home, I plug it in right away. It usually goes from full charge to 80% - 90% and then back to full charge everyday. Whenever I'm not using it I just shut the case and put it to sleep (never turn it off, always plugged in). Recently (In the past month or so), I've been noticing that if I leave Safari open for a few days and then keep using that same, open Safari application to browse the web, open new tabs, etc. it becomes slower to load pages (pretty much noticibly slower). Also, when I have a bunch of tabs, it tells me that I need to reload all of them because something went wrong with the one I was just loading. Also, when I'm multi-tasking; using Safari, and then working in Word, Word will not respond as quickly as it used to. So when I get annoyed that everything usually takes a few more seconds to load/respond, I restart the laptop (allowing all windows/apps to reopen upon restart), and then everything is smooth and fluid as the first day I bought it. I would like to know why this is? It kind of feels like I need to restart every 3-4 days to get everything going back to it's original fluidity. Is this normal behavior? Is it a rogue process slowing everything down? Now, when I say slowing down... by all means this doesn't mean unresponsive, just takes 3-5 more seconds to do things it normally would as if it were new. Is this just the way Macbook Pros work, and they clear some sort of "memory" file or "cached" process upon restart? Thanks for the input, I just want to be reassured it's not some sort of virus per se or some rogue app taking up memory. For the most part, my cup is broken up to: User 5%, System 5%, Idle 90% (although it could be more/less since I'm not constantly looking at it).

Both of my fans are running at the max 6200 RPM and have been for well over an hour. My CPU is over 65% idle, and none of my processes are over 20%. My HD Temp is 38 degrees and my CPU temp is 72 degrees. I don't think my fans should be running this high considering the computer is doing so little work.
View 24 Replies View RelatedI own a Macbook pro 17" core duo 3.06Ghz. I am very happy with the machine, but since a few months the fan's are louder and on much more often then ever before. (the first half year it was always silent) I remember there was some reset for this.
View 2 Replies View RelatedLike 3 days ago I shut down my macbook pro normally. I closed the lid and I noticed that the sleep indicator light was on. I opened the lid and the light went off. I closed the lid again and the light went on again. I got closer to the computer and the fans and drives inside were still running. The only thing I did was to hold the power button down until it shut. This has happened to me 3 times already. I'm kind of worried because I got the computer 2 weeks ago and I'm really happy with it. My computer is a 2010 13' Macbook Pro running Snow Leopard, not sure what version it is.

View 21 Replies View RelatedLast summer my MBP 2.3 GHz C2D was heating up so much, you barely could touch it. So I decided to give it a little hardware checkup. Finding the fans completely stuffed with dust
But after a while i recognized that the fans went on high rpms (around 6000) already at startup and did not lessen anymore. I do not have any high capacity processes running and the temperatures are not just not warm buth rather chilly, so no need for high fan speed. Now I want to solve this problem as well but seemingly nothing will work.

My iMac (intel core duo) after a hard drive replacement seems to be running the fans at a high rate of speed. Usually just a few minuets after startup. Before the upgrade they were almost silent and now they are very noticeable. I need to get taken care of or just a result of installing a larget hard drive?Â

My fans have always been running at 2000 RPMs. I downloaded an app from the mac app store which caused the CPU to overheat, and in order to control this I read that it was wise to download smcFanControl. I downloaded this and added 2 settings, 2.4K RPMs and 2.8K RPMs. This worked to cool down my laptop, and once I realized that my CPU is at 36 degrees Celsius, I set the fans back to the default settings at 2000 RPMs. Now, my fans are constantly running at this speed according to smcFanControl and iStat. My core is cool, not even warm, yet all I can hear are the fans spinning fast to push hot air out of it, when there is none (I've put my ear to it to hear and feel the heat, there is no heat coming out).
I've had this laptop for less than 24 hours, it's a:
15' Macbook Pro late 2011
Intel Core i7 Quad Core 2.4gHz
7200RPM 750GB HDD
Also, this was not occurring prior to downloading smcFanControl (I've turned it off, deleted it, nothing works) - Even after turning off the laptop, the fans stopped, automatically after turning the laptop on the fans came back on. Some extra information: When I put my ear to the bottom of the laptop, it sounds like a vibration.

My last battery popped, and on Monday, Apple store gave me a new one. The lady told me that it was best not to keep the power connected all the time. So I charged it to 100% and pulled the plug. It runs down incredibly fast. This morning it's been unplugged for almost an hour, doing just a bunch of web searches, and it's already down to 37%. This isn't normal, is it? I was able to watch a 2 hour movie on a full charge for my old battery. Does the charge get better over time?
