IMac :: RPM Speeds Of Fans Increase And Boot Time Doubled
Jun 23, 2009
My iMac seems to be a lot more noisier (a low humming noise, maybe the fans), than it was when I purchased it in a couple of months ago. When I first got it, it was the quietness and boot time which I was impressed with more than anything. Now it's noisier and boot times have doubled. I have noticed that the fans for for HD and CPU constantly spin at 1200rpm or more, with no applications open and as soon as I switch on my iMac.

I have a 2010 MacBook Pro, with the following specs; OSX LionIntel i7 2.8GHz (dual core)8GB RAM256GB SSD HDDIntel HD graphics..The issue that I have been having is a sudden, unexplained increase in boot-up time. Yesterday and for the past two years, my MBP took circa 15 seconds to boot up, but today it has been taking approximately 5 minutes. I have the latest software update.My hard drive space is running low; I only have 4GB of space left, could this be a contributing factor? When I switch on the laptop, it get to the picture of the Apple logo, without the spinning gear below, hangs there for approximately 4 minutes, and then eventually continues to the user log-in screen.

CPU cooling fans are running at strange different speeds. 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.

The fans on my 3.06 GHz Intel Core i3 imac run almost constantly and at high speeds. I have reset the SMC, fixed permission, and tested the disk. Also, I downloaded SMC Fan Control. Here are my current readings will the fans are blasting:
ODD: 994
HDD: 5577
CPU: 1200
Temp: 44C

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).

I have a 2 week old iMac 27", i7, 2tb Hard Drive, 16gb RM
In the second week the boot up times became very slow.
I would turn the machine on and get the chime within 5 seconds or so.
Then just a black/blank screen.
Eventually after about 10mins I would get a white screen then it would boot up normally.
Now the machine just doesn't get to the white screen. So I get the chime and then just darkness. It does sound like the machine is on (usual quiet imac whirring).
I've tried various key commands when I turn the machine on including pressing C with the install disk in the dvd drive and the alt, control, P, R pram reset.
I've also tried unplugging all the cables, leaving the machine for a minute and switching back on. I did manage to perform the PRAM reset once. I reset the machine and it booted fine.
But now when I switch it on just darkness.
I've called after sales and will try to get the machine replaced but in the meantime is there anything I could try that might make the machine work? I need to do a remix this weekend (deadline Monday) so really need to get it working.

I have a 1T time capsule. Right now my time capsule is connected to a modem/router from which i get my internet connection. But i wanted to connect my time capsule with a modem to get rid of the router(waste of space,small apartment). But from what i've read it seems that time capsule is awful when it comes to internet.
So what do you thing? Should i do it or not?Don't know if this is important but i have a 8mbps internet connection.

Specifically the hard drive fan runs at 1600rpm and the optical fan always runs at 1350 rpms.
Those fans run faster than my 2007 24" 2.4ghz iMac.
Somehow I figured with the cooler running ddr3, 9400M igpu and better cpu architecture that this new 2009 20" iMac would be dead silent because the fans would barely have to run. Or at least be less noisey.
But that's not the case.
Anyone have any fan speeds to report on new iMacs? Particularly the 20" model?

So I've been using a 1TB Time Capsule for a while now with my old HP and recently purchased a MacPro [15 inch base model]. My room mate has a recent model Macbook as well as an older iMac. We have a 50MBPS internet connection through our local ISP. More or less I am looking for advice on how to make sure our network is:
1. Secure.
2. Faster transfer speeds between all of our computers to and from the Time Capsule. [Where to find / adjust / optimize these settings]
3. Utilize our internet connection to it's fullest potential.
I am mostly concerned with my machine [optimizing it that is.] then the rest of the computers in the house. Go slow and use medium sized words as I am still wading into the world of Mac.

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.

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?

I have a 15-inch MBP (2011) 2.3 GHz, Core i7 with 8 GB of memory and a Vertex 3 MAX IOPS SSD. I'm running Mac OS X Lion 10.7.4.As you can imagine, this is one quick system. When I first installed Lion (I did a clean install on a brand new SSD when Lion came out), my shutdown time was literally under half a second. Then a few days later, as I installed my usual apps, I noticed that the shutdown time suddenly went to 20 seconds with the usual grey screen and spinning wheel. I figured that one of my programs must be causing this, but could never figure out which.After living with this for months, I decided today to use Activity Monitor to try to quit some processes to see if my shutdown time would go down. After a few tries, I noticed that just starting and quitting Activity Monitor brings my shutdown time back to half a second..
I repeated this over a dozen times. I start my system and immediately shut it down: it takes 20 seconds to shutdown. Then I start it, run Activity Monitor and then immediately quit it, then shutdown: it takes half a second to shutdown.I can obviously live with a 20-second shutdown time. I don't shutdown often anyway and the system is super fast otherwise. But it's still nice to get to the bottom of this.

I have a new mid-2009 iMac 24 inch 2.66GHz. I work in a quiet environment and most of the time the computer is idling along. iStat returns the following fan speeds:
CPU 1200
HDD 1600
ODD 800
Even when I drive the iMac a bit harder - 100% CPU for an hour and a half - the temps only rise as follows:
CPU 60 C
Northbridge 68 C
Power Supply 71 C
and the fan speeds do not increase.
I value silence, and it seems to be unnecessary for the fans to running at this speed when they are not needed most of the time - when the computer is not under any load. With the iMac everything is right in front of your face. I heard about iMac Fan Control and installed it, but there is no possibility to set lower-than-standard fan speeds, except for the HD which can be set to 1200 instead of 1600. However, the ODD minimum speed increases to 1000 from 800.

I was having problems with overheating last night in Windows 7 in that a few apps started freezing and I noticed that the top of my iMac was scorchingly hot even when I wasn't doing anything. I downloaded MacFan and used it to up the minimum fan speeds, and it worked as I wanted it to. Upon rebooting into Mac OS X, however, I think the fan speed increase carried over and was excessive, because I can hear my fans going even when I'm not doing anything and the top of my case is barely even warm (whereas before it was somewhere between very hot and painful).
I opened up smcFanControl and it's reporting ODD/HDD/CPU speeds of 2000/2500/1500, but it also has those numbers as the listed minimums on the sliders, so I can't decrease them beyond that. I'm pretty sure I can get around that by hacking the preferences file, but that requires that I actually know what the default Apple fan speeds are. Can someone with an i7 iMac who hasn't messed with their fan speeds open up smcFanControl and tell me what the minimum speeds are?

has anyone ever tested the boot time of Windows 7 running on iMac 27'' SSD? If you boot Windows 7 on SSD with VMFusion 3 or Parallel 5, what is the boot time? I am concerned because the main reason for me to get an SSD is to get a faster Windows 7 boot time.

I have the 27" inch quad core i7 imac I just got a few days ago. Some reason for certain things like d/ling the vlc players its taking a few minutes to d/l a 24 meg file. With this type of computer, it should take like 3 seconds to d/l a small file like that. I have a fast internet connection, don't understand why that's happening.

i have verizon dsl and live out about as far as you can and still get dsl.
the problem im having has just been since i got my new imac. it will start downloading around 85-90 kb then just slows and slows consistently and gets around 10 kb. sometimes if i stop then resume the download it will start back up at the faster speed but then slows again. sometimes if i stop it, it cant resume for some reason.
is this my isp problem or is it something with my computer or settings?

I've had problems with my Mac for a while now. First of all, it indicated ram problems with 2 beeps. I later fixed this by moving and changing around modules. It was solved, but now a new problem. The Mac seems to turn on, making its iconic sound for startup, but the screen remains black. After about a half to one minute, the fans go crazy and I have to shut it off. I've tried a few things like holding shift or alt, but that doesn't work as it doesn't even display a white screen.Â
I need to know what to do and I don't really have the time to buy new parts right now. I'm really a windows based pc fixer by the way so I'm new to fixing macs.Â

i have 4 gb of ram, and would like to increase the shared video memory in windows 7, that i am using via boot camp. i know you can do it using the bios, but because there is no bios, is there any program that emulates the bios for boot camp, or another solution to do this?
then, why does windows 7 read just 3 gb of ram, when i have 4?

I rarely run Boot Camp but whenever I'm using Boot Camp on my 13" MBP [Summer 2009 model] it really heats up a lot. I generally use IE8 or Google Chrome, & the Zune software. Not much besides that to be honest, occasionally I used MediaMonkey as well.
Anyway, point is for some reason - regardless of programs running - the notebook appears to be getting extremely hot.
I want to increase the fan speed while in Boot Camp so it doesn't run so hot. Any ideas/recommendations as to do doing this?
In OS X [10.6] it works perfectly fine so definitely something related to Windows drivers but increasing the fan speed should remedy, no?

I just recently bought an imac computer and my two friends who know a lot about apple computers thought that the fans and temperature might be a little high. The cpu fan at idle runs at just under 1200 rpm's, the harddrive fan runs at 1100 rpm's and the optical drive fan runs at 1000 rpm's. The temperature itself 40-44C. The other imac that they know of is a year old, so we weren't sure if there were newer upgrades that might be making the difference between our speeds and temperature compared to that one.

Help! My internal fans speed up on boot (sounds like a jet engine!) and don't ever stop! My machine doesn't get past this phase, either. I have reset the SMC, and was cleaning the system for dust, etc, just before this situation occurred. After the cleaning, I was able to boot up fine. Then I had to re-open the machine and adjust something. I put the panel back on, rebooted, and the fans churned up like a Blackhawk helicopter, and didn't stop!  So, I unplugged the power supply, waited ten minutes, then reconnected the power supply and powered the machine on. The same result! The fans just don't stop. Â

I finally bought my Mac Pro last week, and needless to say it continues to impress me. I was transferring some files from my 1tb Seagate 7200.11 to my boot drive consisting of two 74gb Raptors in software raid 0. Since i've had it, the 4gb files have always transferred at about 60mb/s, but tonight the speed somehow managed to double to a maximum of 127mb/s (and a sustained 100mb/s). Why would the transfer rate double in speed?

I searched for this up and down and for some reason can't come to a solution.
I was making a double-backup of my music folder (merely copying the folder over to another external hard drive), and I noticed my mp3 collection has doubled in size!
I've tried finding duplicates but it pulls up a very short list of the usual suspects that I know aren't dupes. I looked in my music folder directly only to see my regular mp3s with no duplicated files.
How do I get rid of these "phantom" mp3s?

First of all here's my setup: 30d/4u Charter internet coming in through my Linksys modem, from there to port 1 of my 2006 Intel Xserve running NAT and DHCP, out from port 2 of the Xserve into my AirPort Extreme running in Bridge Mode, and then out to my other devices.Â
My AirPort setup is as follows: Internet tab-DHCP, address set by Xserve; Wireless tab-Create a wireless network, WPA/WPA 2 Personal; Wireless Options...-5 GHz network name is not checked, Radio mode is set to 802.11a/n-802.11b/g/n (Automatic), both 2.4 and 5 GHz channels are set to Automatic; Network tab-Off (Bridge Mode).Â
I am transferring 100+ GB of data across the network to my Xserve, but it is only Xferring at 5.5 MB/s, or around 44 Mbps, which isn't even at wireless-g speeds. My iMac is the Mid 2010 27" BTO w/ 2.93 i7 and 8 GB of RAM. It is also wireless-n compatible.The Xserve is wired and they have had gigabit NICs since the G5s.Â
Things I've tried: In Wireless Options... I tried turning Radio Mode to 802.11a/n-802.11b/g and leaving 5 GHz network name unchecked, but the speeds were down in the 2 MB/s range. Again in Wireless Options... I checked the box for 5 GHz network name, and left Radio Mode in Auto, joined the 5 GHz network on my iMac, tried again, but again only 2 MB/s or less. In Wireless Options... again, I checked the 5 GHz network name box, and set Radio Mode to a/n-b/g, but ocne again, it ran at 2 MB/s or less. The AirPort Extreme is model A1354, which is obviously 802.11n compatible, and the iMac is also 802.11n compatible. Â
