PowerPC :: IBook's Fans Louder And Faster
Sep 1, 2006
My iBook just fell of the table, and now refuses to power up. Never again will i say the magSafe is pointless. I (was) running a 800mhz, 640mb G3 iBook, 10.3.9, bought in 2003. The laptop landed on a connected usb cord, which has damaged the usb socket, with the white plastic bit inside the port now broken off, leaving exposed connectors. The laptop did power up initially after the fall, but upon connecting another usb into the remaining usb port,the iBook's fans came on, louder and faster than ive ever heard, before dieing. I simply cannot afford a MacBook right now, and had just upgraded the RAM and OS (10.2.8 - 10.3.9) so that it would last me another year.

New 2.4ghz MacBook aluminum owner here. There a very low hum coming from my new MacBook, and it is always there. I don't know if it is the hard drive or the fan, but is is quite obvious in a quiet room.
I compared it to my 2003 plastic iBook, and the iBook is SILENT compared to the new MacBook.
I checked the iStat Pro stats, and the fan is around 2000rpm and the temps are normal.

Right now I have a G3 iBook (900 MHz, 640 MB RAM, Combodrive, 40 GB HDD). I'm looking at a G4 iBook (1.2 GHz, 768 MB RAM, Superdrive, 60 GB HDD).
How much faster would the G4 be over my G3. I figure that after selling my G3, the G4 would only be another $200ish on top of it. Would this be worth it?

My father owns one of the original G5s, so its power pc not intel. Today while browsing an excel spreadsheet he says part of the screen turned black, then the monitor shut off, then the monitor came back on but not video. Mean while the fans started spinning out of control. Now when he tries to turn it on, he gets power, but all that happens is the fans spinning faster and faster and faster until he turns it off. No video or anything. Just speeding fans. He fears the CPUs died since they control the fans. Any suggestions? He also says the fans were spinning unusually fast these last few days.

I 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.

I have been enjoying my recently acquired pismo g4 500. Typing on it feels wonderful, and I'm so glad that I got it. We also just got an ibook 1.2ghz (768mb memory), and for some reason, the pismo loads internet pages faster.

Does any one know if I can put a faster logic board in a 12" 1.07 ghz iBook? Something like a 1.2 ghz from ebay or something? Would it use the same ram?

I have an iBook 500Mhtz PPC G3, 384 RAM, 10GB HD, Dual USB. Several months ago, I opened it up and it simply would not start up. No start up sound, no noise from the fans/HD/anything, motionless. Completely dead. I've held (many times) the PMU, and tried almost anything. Is there anything else I can do to get it to AT LEAST turn on? The battery is dead, and the charger is fine, but the battery won't charge. I tested the charger on a PB G4. I'd rather sell the whole computer as a working computer. I figured I'd get more money that way. do I need to sell it for parts?

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)

I've had my macbook for a good 2-3 years. I put in a movie and heard it vibrating and clicking. It then started to make a noise and got louder and louder like it was going to explode. I searched some forums and someone said that it means your hard drive is dying. What do you think it is? should I go into Apple and have them look at it?

This is a odd question, but are Intel macs louder than previous macs? I just recieved an Intel iMac as a replacement for my dead iMac G5 and both myself and my family has noticed a loud sound (Sounds like a needle playing on an old record player) which is coming from the iMac. My first iMac was very quiet, however when I start using the new iMac this odd sound keeps happening. Is this normal? I am just worried that this scratching sound might by evidence of something breaking down. Also the sound is a lot louder when under Windows XP.
PS: the sound is loud enough to be picked up on the internal microphone, however I don't know how to link the file to Macrumors.

I have an old G4 and its memory is to the max 1G. I'd like to know what you would reccomed to make it work faster. I've heard that an accelator for the processor is an alternative. Is it really worth it, and does it really work that good? I work with Photoshop all day long and handle very large files.

I have a G3 iBook and just the other day the display stopped working. There were no signs of the display going bad, it's just went. Am I able to boot the iBook via Target Disk Mode on my PowerBook and run the iBook Hardware Test CD on it? Also, can I reboot my PowerBook and choose the iBook as the startup volume?
I know how to do Target Disk Mode but the latter I'm not sure about.

I've tried searching but this is somewhat of an unusual comparison. I've got an older Dual 2.0 PowerMac G5 w/ 3GB RAM, upgraded 1TB WD HDD. I use PS4, LightRoom, iWeb, iPhoto, iDVD, and it is also dual monitor out to a projector in my home theater. Upgrading to a new MacPro would be ideal but I can't spend $2300+ right now.
How do you think the new 2.66 mini w/ 4GB RAM compares to this old G5? I think the new mini can do dual monitor output. Other than that the mini would seem to suit my needs for faster CPU.
Can anyone give an opinion and/or point me to where I can read about this type of comparison?

My brother's iBook G4 (800Mhz, First Rev) has completely splattered itself and we're getting a new Macbook for him under insurance. My iBook G3 (White, 900Mhz G3..the last G3 Rev of the iBook) has a failing hard drive.
Now, could I swap out those two drives, at least to recover stuff? And is there a specific method of opening up the iBook G4 so that I don't break stuff (I've already messed with my G3..and ended up with a dozen extra screws ^_^
Mainly the aim is to salvage the hard drive and swap them out; replacing my faulty iBook G3 one with the iBook G4 one which is perfectly fine.

My G4 12" PowerBook will not burn DVDs with the newer 8x or faster DVDs.
It has the 2x burner in it and I have't been able to burn DVDs since I ran out of 2x disk some time ago. (I can't find any 2x disk around here any more.)

Is the etherent port that's on the powermac g4 a gigabit or whatever port? Or should I buy a new faster ethernet card for it?

My PowerMac G5 fans hardly ever speed up. I mean they certainly never go full speed or ever close how they sometimes behave on start up. I never get the jet speed noise. Even when I am rendering a movie in FCP, I hardly hear the fans. Right now on idle, iStat pro reports CPU A being 58C and CPU B being 56C. Yet, the fans are still only 400RPM both CPUS Intake/Outake.

I'm trying to record something through the internal mic (and I'm too cheap to go out and buy a proper mic) and I was wondering if there is anyway through Terminal,or an external program, to force the fans to shut off for a certain period of time? I don't want to turn them off to find they can't turn back on and suddenly the computer is 1000�...I just want to keep them off to have a minimal amount of background noise. (And, yes, I'll be running it in a moderate climate so the computer doesn't overheat).

I have a strange problem with the powermac G5 1.8 SP, yes the one with the hardware bug. It was my first mac, what a dissapointment. The bug was partly solved with the firmware upgrade, but after that it still behaved strangely. The fans suddenly go up to maximum speed every hour, then quikcly return to normal. There still have been lockup's / beachballing with USB, and overall slow performance.Now I am running the latest mac osx Tiger version, about a few weeks ago, the fans start revving up almost to maximum, all the time, regardless of cpu load. The cpu temperature reads about 60...65 degrees centigrade when idling (minimum cpu load), cpu setting is already on "reduced speed". After switching-on, cpu temperature is already 60 degrees centigrade. The cpu heatsink is stonecold, as is the exhaust airflow. The cpu 2 fans roar like mad and keep revving up and down. When I remove the plastic transparent cover, the photocell is activated and a red LED comes on, now the fans immediately return to normal speed. Anybody else had similar problems wit the powermac G5 SP 1.8Ghz ?

I have this Power Mac G5 and every now and then it'll freeze up, the fans will go full blast, and the screen will go black. It's not even when I put a heavy load on it.I usually just hold the power button down and do a hard shut down. Does anyone know why this G5 keeps doing this? Should I re-seat the ram and GPU?

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.

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 opened up my G5, to install more RAM, and saw that one of the hard drives was unplugged (I just got it used), and so I connected that, blew some compressed air into it, installed the RAM and closed 'er up. Then I tried to power on and it didn't work (No Chimes, just fans spinning, no video, not even the start up chime). So, I disconnected the hard drive, took out the RAM I put in, and closed it, and it still doesn't boot. Same thing. My keyboard is wireless, but the wireless dongle thing doesn't get any power when it is "powered on". The fans are spinning all the time. (Except when it's powered off, obviously)

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.

My CPU fans for proc.A are near-constantly capped at 300rpm(system minimum), no matter how damn fast the B-fans spin to compensate.I have: Kept it clean inside. Kept CPU settings on Highest, as usual, but tried Reduced/Auto Repaired permissions Reset the PRAM Reset the PMU Booted into single-user mode Reinstalled Leopard
Obtained & ran Service Diagnostic CD and passed all tests Re-calibrated the CPU's only to notice the speeds now hover around 400rpm now What more can I possibly try? I don't believe a re-seating of CPU's is in order. They work great. All my fans & temperature sensors passed their diagnostics tests, too.I am very irritated by the noise of 2/4 fans overcompensating and getting very loud, from 2000rm-4000rpm, and hey, my Mac is screwed up, and I really need to fix this.

I just bought a parts ibook from ebay, but I managed to fix it, except there was no hard drive. I currently have a 6 GB HD in it with OS X.3.9 on it, but I want tiger. I have the tiger family pack, so I have a license for it. It only has a CD-ROM drive, so I am wondering if I can buy a 40 GB HD, and clone the one from my G4 onto it.
SPECS
ibook G3- 500 MHZ
192 MB RAM
CD-ROM
currently has 6 GB HD
ibook G4- 1064 MHZ
1.25 GB RAM
Combo drive
