Mac Pro :: Fan Loud And Constant - Apparently Believes Core 4 Operating At 260 Degree
Oct 18, 2008
As the header says, the fan in my Mac Pro is now operating at a constant 2700 rpms and, per iStat, believes that Core 4 is at 260 degrees. This is from COLD startup as in overnight. All other cores are operating in the low to mid 70s. So, obviously it's impossible for core 4 to be 260 degrees on startup and highly unlikely it would be that hot, ever. I've done the SMC RST thing both ways (button pushing and unplugging).

I have been presented with an iMac G3 400Mhz. It has an annoying loud whine. The whine is constant and high pitched. I am thinking exhaust fan. Is my thinking correct? Is it hard to get to and replace?

My family just recently upgraded from an old PC to this 27" iMac, during the early part of the summer. While using it over the last little while, I would notice a noise that sounded like a harddrive spinning or possibly some sort of a fan noise. The best way to describe it would probably be as digital noise. It's not incredibly loud, but it's a decent volume, and can get quite annoying. It has a little bit of a squeak to it.
Over the last little while, it's become more constant. When the computer is in use, it'll usually occur quite often. It's quite annoying and obtrusive when I'm watching videos and I'd like to know what it could be.I think our computer is still under warranty, so I'm hoping to find out if it is something wrong, so I can get it replaced.
I've also been wondering if it's a fan, or a regular noise. However, it's so constant that I'm starting to wonder. The other night, I was watching a video and it seemed like it was coming on every 30 seconds for a long span of time. We don't run any memory heavy programs on this computer. If anything, we're just using Firefox, iTunes and/or Messenger. Sometimes Office. There's little to nothing stored on this computer, as it's brand new, so most of its memory is free.

Starting today my 2010 Macbook Pro 2.66 GHz Core i7, OS X 10.7.3 (8 gigs ram) has experienced 4 "hard freezes" where the system locks up, itunes plays the same second of audio over and over, and nothing works (keyboard, trackpad, etc.. all frozen). You can't even make the caps lock key light up. This requires you to hold down the power button to reset. Obviously I'm very concerned that this is a hardware failure... or something is getting too hot. The thing is I'm not doing anything that crazy, no games or tons of programs open.

2 days ago i received my new mac pro 6-core 3,33GHz...now something really weird and super annoying is going on with this computer...From time to time there is this really loud POP trough my speaker. I'm absolutely 100% sure this has nothing to do with my amp. cables or whatever and its definatly a problem with the MacPro, i know because of the following:
Plugged in new cables, removed every installed software, plugged onto different amplifier, when there are absiolutely no audio cables plugged into the computer and when i use the build in speakers of the mac pro i still hear the POP/distortian like sound, and finaly even took it at my friends house and tested the machine there on his audio instalation...problem remained! not knowing what to do next i decided to go and see a very good technician (music instruments and studio recording) and told him about the problem, he imediatly stated that it "could be" because of the harddisk drive giving like electric impulses or whatever that causes the distortion...or that the sound card or audio chip set waking up from sleep and every time it does there is this loud POP?..................

I just bought my MacBook Pro last week. When I power it up, it makes a loud noise for about a second and a half. I think it's the hard drive starting up or the disc drive. I'm not sure which one, but it's pretty loud, so I was just wondering if anyone else noticed this and if it is normal.

I Got a 13 inch MBP and gave my 13 inch aluminum MB to my dad. However i noticed something with the new MBP i got. A)After installing istat pro on both machines only the older MB shows as having Heatsink A and B, the new MBP shows as only having Heat sink B, how come? The aluminum MB on boot up has all the temps (CPU, Heat sinks, HD and so on) going around 20-30 degrees FH, yet the MBP is coming up with 90-130 degrees FH. After 1 hour use the MB has all reading between 28-48 yet the MBP has all readings between 90-140 degrees FH. Both kept in the same room, doing the exact same thing (running safari, same site). I just dont want the nightmare i had with the MBA where i had to return it 3 times because it would over heat and crawl when doing anything slightly intensive. Mine are:
HD MACINSTOSH 83
CPU 131
ENCLOSURE BASE 90
ENCLOSURE BASE 2 90
ENCLOSURE BASE 3 89
ENCLOSURE BASE 4 91
HEATSINK B 113
NORTHBRIDGE 108

It either interprets "diagonal" scrolling as horizontal or vertical, or left and right. There is no horizontal and vertical at the same time. I don't recall my previous MM being able to scroll diagonally, either. I'm not sure what Apple means by "360 degree scolling."

This is an unfortunate development! It appears that one of my processors has died on me! Is this, in fact possible - and still be running? I have included a screen shot, using Temperature Monitor to show the processors and ambient temps. What other way could I determine if it truly dead? And lastly, can a replacement be had? (I'm fairly adept at computer repair) If so, where?

I have two terabyte hard drives in my desktop. Since I barely boot the desktop anymore, I pulled one out and hooked it up in a USB enclosure. I was using it to watch movies off of. I made a shortcut ("alias"?) to the drive (which was mounted using NTFS-3g) and put it in the movies folder so that I could access it from frontrow. I had a bunch of seasons of Seinfeld, Simpsons, and Family guy that i ripped from DVD using handbrake, but there was also backups of alot of my Software CD's on the drive. Nothing I can't make again from the originals, but a pain to do.
Regardless, all of a sudden (A day after hooking it up), everything is gone. On the Mac side, I just see a folder labeled "System Volume information". I unplugged it and plugged it in to windows and I just see a couple files that get created by Mac OS ("trashes", etc), none of my actual data. Both sides, however, recognize that only 27GB is free on the drive which leaves me some hope that I haven't lost everything. Does anyone have suggestions for recovering this stuff?
The drive is a WD Caviar Black 7200RPM 1TB disk. As far as I'm concerned, they are the best 1TB drive made from a warranty / reliability standpoint, but obviously disk failures do happen....this doesn't seem like a HDD failure to me though as the drive *seems* to be working correctly. I tested it with HDTune and the transfer rate is still the same, so it seems like something got corrupt somehow (not a mechanical failure)...

Okay. So my Airport has decided that I apparently have no IP address. I know this is somehow my fault, and I've tried resetting it via terminal, but each time I fix it, I have internet connection for about 5 minutes and then it cuts out again. I've looked under my network settings and there's absolutely no IP address. Nothing. I set up one of the Google servers (8.8.8.8), but that is only getting me so far. I just don't know what to do next. I'm running Lion, because I know that will make a difference in how everything is set up. I have also tried to release a new one via DHCP, but that doesn't do anything when I try it.

My son spilled a diet coke on my macbook. It mostly got on the keyboard and monitor. I removed the power chord, turned it off, and wiped off the soda immediately. But of course it's liquid so it is probably moved under the keys right? I turned it back on a few hours later and there doesn't seem to be any problems. Is it possible there was no damage?

I have a late 2008 uMBP 15 inch and in safari, regardless of using the integrated graphics card or the higher end card, when I press apple t for a new tab the computer hangs for at least 10 seconds then once it finally loads the top sites page it appears all scrambles for a second, then it works normally.
My second problem is that my hinge is very loose. I can't hold the laptop at 45 degree angle without the screen falling down and closing. Will apple fix this?

I see the numbers of everything from Core 2 Duo, to the slightly faster and cooler Core i3, to the supposedly faster core i5s and i7s. The benchmarks go up accordingly, but I found this does not always equate in a faster experience on most tasks.
Here's my experience so far on processor upgrade:
In one computer trade school re-certification class I am in, we are working with Windows Server 2003 on a Quad Xeon platform and it's incredibly slow.
But in a previous class we had the previous generation server edition on older Xeons, and while not fast, it was much better. On paper the newer multi-core Xeons should have made a difference, but could 2003 server software be that much more bloated than the previous Windows server edition that it would stall like that and make us wish we had the older setup?
I am going to try out the Adobe CS lab and put the new high end Dells to the test there and see if they work better than when we had an older CS version on older Xeon equipped Dells.
I don't know if this is something to do with Dell, or if Apple's increasing processor bumps/generations are going to similarly not make a difference in the speed things appear to go at, whether it's Adobe stuff, server stuff, or anything else that needs power.
I know somebody who plans on a Core 2 Duo, i5 or i7 MBP and I was wondering if the higher end processor is worth it in that case (iMovie being the main program of use).

I have an opportunity to get a single 3.0 GHz quad core Clovertown.
Should I go for it? There's no advantage to having two cores in two sockets versus having four cores in one socket, right?

is it even possible to upgrade an old dual core powermac g5 to a quad core or even an 8 core.
I have a dual core one and i really need to upgrade to a quad or even 8 but it is so expensive to buy a whole brand new one and i was wondering if there was a way to just get a new processor and more ram or what not.

So the older Mac Pro's from 2008 have 2 2.8ghz Quad Core Intel Xeon processors, without hyperthreading, for a total of 8 cores, and the top of the line iMac has a Quar Core i7 2,8ghz with hyperthreading for a total of 8 (virtual) cores.
With the ghz being the same but less "real" cores, but probably newer CPU architecture, which CPU will actually be faster?

There's a lot of people wondering if the 13" MBPs would have been a lot better with a Core i3 processor, but everything has been just hangups over perceived old vs. new technology, and really the only thing the Core i3 adds is Hyper-Threading, but it doesn't have Turbo Boost, which helps the Core i5/i7s tremendously. Let's compare using Geekbench since it is cross-platform and one of the few available sources of info...
Core 2 Duo P8600 2.4GHz (~3362)
[URL]
vs.
Core i3 330m 2.13GHz (~3472)
[URL]
Core 2 Duo P8800 2.66GHz (~3700)
[URL]
vs.
Core i3 350m 2.26GHz (~3680)
[URL]
As you can see in both cases, the difference is pretty minimal indeed, and in single threaded applications, the C2D will easily outdo the Core i3 which lacks Turbo Boost and runs at lower clock rates.
And you get a 320M instead of Intel HD graphics with the new 13".
The Geekbench results from the old 15/17" to the new 15/17" are quite an order of magnitude better.
So unless people are expecting Core i5 processors in the 13", sticking to the C2D was actually a good decision, and given the differences between 2.4 and 2.53 isn't so large, one is far better buying the base 13" and then putting the money saved towards a good 7.2k HDD or SSD.
Note - I took averages of the 32-bit numbers and added them.
Note 2 - The C2D Pxxxx are 25W TDP processors, which are more efficient than the Core i3 which are 35W TDP processors. Less heat, better battery life from C2Ds.

I've been debating whether or not to upgrade my 3 year old 15" Macbook Pro that has a 2.2Ghz Core 2 Duo (Santa Rosa) to the new 13" 2.4Ghz Macbook Pro. FYI... My current system also has 4GB of RAM. Since both systems are Core 2 Duo, what kind of speed bump am I going to see? Would this be a substantial upgrade?
