MacBook :: Fan Speed Over 6000rpm When Not Using Intensively
Jul 16, 2009
When I use my mac, at no particular time, the fan speed just shoots up to over 6000rpm (according to iStat pro): and I can hear the difference from the laptop, it's very loud compared to normal fan speeds. It lasts about 5 minutes before returning to a normal 1800rpm (ish). I took it to a genius to ask them, they ran diagnostics on all the hardware and said there was nothing wrong with it - however there obviously is! The screenshot below shows the dashboard displaying fan speed, it also shows that I only had Firefox, iTunes, preview and google desktop open! The fan speed is only around 2000 if I have parallels, skype, office, cyberduck, vlc, adium, ichat, evernote open etc!
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.
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.

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 am interested in adding a webcam to my desktop Imac (power pc)- Isight is no longer available- an option that I found is the Ecamm Image- but apparently it is USB and not firewire and it will only run with high speed usb- how do I know which type is on my computer? I checked system profiler but quite frankly wasn't sure of the designations.. does anyone have any experience with this camera, by the way? is USB 2.0 by definition "High Speed"?
I have a WDS local network at my house. I use a Airport Extreme in my main part of the house and a Airport Express for my back part of the house i.e. the backyard. Now every two weeks or so my internet speed through my Airport Express slows down about half the speed but when I am connected trough the Airport Extreme my speed is normal. I know this because I test my connection very often. Now when I want the Airport Express to get back up to speed I have to unplug, and plug it back in. Then after awhile it starts to slow down again in a time period of two weeks or so.
Have an Extreme base stations and express repeater connected to my DSL services. On my primary iMac connected via ethernet I get 5.25MBps speed. The speed on this computer is always constant. On the remote MacPro I get anywhere from 1.5MBps to 5MPps speed within a half hour of testing.
I'm using Data Rescue III on a USB powered hard drive with and it's taking a very long time with my iMac G5... It says 42,291 hours remaining (about 5 years) If I did it on my Mac Pro would it go faster, or is the recovery speed based on the hard drive speed?
i have a 1.5 Mbps AT&T DSL connection, and multiple speed tests show a download speed of 1.2 Mbps (and 200 Kbps upload). when i download files, such as software updates from Apple, various podcasts, and even Silverlight from Microshaft, the speed is always between 140 - 160 Kbps. i contacted AT&T, and the rep said it was because of buffering by the servers i was receiving the files from. is this a reasonable explanation? is this an accurate use of the term "buffering"?
Last night my fan kicked into high gear all of a sudden. I shut it down overnight and when booting up this AM I find it still running on high...quire noisy, of course. Is there something overheating? How to make it run at normal speed?
I generally get about 700kbs download speed, which is what my ISP (Sky uk) tells me I SHOULD have, but they also tell me that my router upload speed should be similar and it's not anywhere close to it.
I find OS X's TTS engine on SL to be not fast enough on full speed. Is there a way to hack the plist file or something to speed up the dictation past the max speed?
I've got a real odd problem with safari 4. For some reason it is cutting my download speeds in about 1/2 from my server and many other places.
If I restart safari I will be able to download close to my 18 Mbps for a little bit but then it will just start to slow down and after about 30 minutes it will be down to about 6 - 8 Mbps.
Ok so I made an imovie that was like 20 minutes long and to do that I had to scan in like a billion pictures and all that. I deleted all the pictures of my computer when I was done with the project. But I have noticed that ever since I started this myy computer has become much slower. This imovie was the first big project I have done on my mac. I clean my disk drive thingy like ever 2 days using Disk Doctor.
So my 4 year old macbook has a logic board problem where it no longer detects the battery. The battery indicator just shows an "x". So basically it works fine but it has to be plugged in all the time. I've heard that if a Macbook does not have a battery in it and is just running off of AC power, it will cut the CPU speed in half in order to cut the power consumption. I want to see if this is true or not. I have ordered a new MBP but I was going to sell this computer for my friend for very cheap, but I need to make sure its not actually running at 1ghz, cause I'd feel bad about selling him something like that. The computer is perfect otherwise.
Seriously, for the life of me I cannot find it. I've looked in System Profiler and Disk Utility to no avail....am I overlooking something here? I thought it would be obvious; I simply want to know what the RPMs of my installed drive are.
ps Amazing how a 320gb drive only registers about 195 or so...is that right? I know when the drives are formatted they don't register the full capacity but losing 25gb seems a tad much to me.
I am running Leapord on my Blackbook and it it seems to me that it is running a lot slower than when I first got it. Is there a program out there that will help me to speed it up again?
I'm trying to figure out how does the cooling system in MBP's work. I've been using FanControl for quite a while (the one by Lobotomo), it does the job pretty straightforward - just dynamically changes the fan speed. But when I was using default settings the fans were at low speed even when temp was around 80C. Any idea what default settings for Apple notebooks are? I mean, lower and upper thresholds, how and when does it kick in the fans etc.
I was working with my MacBook Pro today when all of a sudden, it randomly shut down. It took about 5 minutes before it would turn back on, but now the fans run at max speed constantly, and the battery indicator just shows an X over it. It's as if the MacBook doesn't recognize the battery at all, even though I can run on battery power.
Under Lion my 2010 (HDD) Macbook Air has been intolerably slow. It could take 10 minutes to start a program. When connecting to a projector, it could likewise take 10 minutes for it to resize windows during which it was unresponsive. I have been about to hurl it in the trashcan because this computer was just such an impediment to my work. But now I found the solution: don't run Safari. I had long suspected 2G ram combined with a slow HDD was the culprit. I tried to minimize the number of programs open, but let Safari run permanently. But it turns out Safari uses enormeous amounts of memory, and it has a tendency to just grow and grow its memory grab. Now, I quit Safari when I want to run other programs, and after this the computer is merely slow, not intollerably so.
Is there a way to measure actual CPU speed on OS X? I have tried MSI tools and that doesn't work (at least the version I installed doesn't work, if anyone has a download link that works I would be willing to try it) view my current CPU speed in GHz.
I purchased a 16GB PNY Attache and cloned my hard drive before I installed anything on it. My only reason is for backup and to run a few utilities. It seems to be a little leisurely when I boot from it though. Does anybody know if there are faster read and write ones or is this as good as it gets?
According to istatpro my fan exhaust speed when not doing anything (ie straight away when I turn the laptop on) is 1800rpm and I can hear fan noise on the right hand side when just sat normally using the laptop (ie not with my ear to it!). Is this fan speed and noise normal? Because on my old powerbook, when doing nothing, made no fan noise at all.
