HD and Fans

WOuld switching the internal HD from a 5400 to a 7200 rpm on a MBPro kick start the fans a little more often or is it simply my impression?
The unit seems to run a little hotter, but then again, I could be mistaken.

Hi,
due to the higher rotation speed of the 7200 HD it produces/emenates more heat than a 5400 HD.
That's normal expected behaviour.
But usually the MBPs can handle this very well with the fans kicking in earlier and/or running at a higher speed.
If not doing this already, you might wanna use something like iStatPro to monitor the different temperatures of your MBP.

Stefan

Satellite A505-S6973 overheating and fan works often

I hate doing this but I seem to have encountered another problem which i have been searching and reading with the hopes of correcting myself. I presently own a Satellite series laptop with an Intel Cor 2 Duo T6500 2.1Ghz processor.
I 've been monitoring my system for performance issues andi've noticed that for sometime (unsure when) the temperature on my system has risen significantly. I'm seeing from my PC Health Monitor that my processors temperature is running at 59% and fan speed is at 78% yet when I place my hand near the cooling fins at the side of my laptop I can barely feel any breeze but a co-worker of mine has a vostro and the fan feels like it's running on NOs.
If there is anything that can be done I'd greatly appreciate this, i'm afraid of loosing my system due to something simple that cause overheating.
N.B. I noticed that at one time different users posted threads stating that after updating there BIOS they experienced overheating problems. If this is the cause of anywhere near it please help.

Are you sure that your notebook is overheating?
In my opinion you cant compare this with other notebook models because every notebook has its own cooling modules and fans and there are not standard parts as on desktop computers. Furthermore its also important which form factor your notebook has. Larger and bigger notebooks have a better cooling assembly as smaller ones.
Anyway, in my opinion you could try cleaning your notebook using compressed air spray. This should always be done from time to time to blow out the dust from the cooling ventilators. Therefore its not necessary to disassemble the notebook.

Powermac G5 stuck on grey screen start up and fans running wild

Hi All
I also have the recurring problem all of a sudden - yesterday all seems well, today am stuck on grey screen and fans getting stronger by the minute. NOTHING works - have been through all sorts of forums and the most I got was to try disk utility - which says all is well - replaced the battery - tried just about anything short of pouring some acid on the **** thing, won't boot from original install CD either - I really need this machine as I earn my living with it and cant afford a new one and why as it was working just perfect - now this mess. In a way don't know why the excellerating fans are not built to simply pick up speed and then eat into the PC board and CPU - at lest this way we know for sure there is nothing we can do.
Does no one here know why the mac is doing this - not even the mac fundies? Unbelievable. I live in Namibia and Apple Mac support here is similar to that on this website - might as well write this on a wall - that is why I am really frustrated... **** Mac

Follow these steps in order:
http://support.apple.com/kb/TS2570
The G5 is also subject to solder failure around the RAM slots and memory controller.
It is a fatal condition, but one that can sometimes be temporarily sidestepped by heating the logic board between the RAM slots with a hair dryer.
Heat the board until very warm (hot) then start.
If your machine starts after heating, then you better just leave the machine on all the time.
You never know when the trick won't work......

The kernel is using excessive processor cycles. Below are some possible causes for the condition.
Throttling
When it gets high temperature readings from the hardware, or low voltage readings from the battery of a MacBook, the kernel may try to compensate by interrupting the processor(s) to slow them down and reduce power consumption. This condition can be due to:
☞ a buildup of dust on the logic board
☞ high ambient temperature
☞ a worn-out or faulty battery in a portable
☞ the malfunction of a cooling fan, a temperature sensor, a voltage sensor, or some other internal component
Note that if the problem is caused by a sensor, there may be no actual overheating or undervoltage.
If the computer is portable, test with and without the AC adapter connected. If kernel_task hogs the processor only on AC power, charging is causing the machine to heat up. That behavior may be normal for some models. CPU usage should drop when charging is complete.
Apple Diagnostics or the Apple Hardware Test, though not very reliable, is sometimes able to detect a fault. For more thorough hardware testing, make a "Genius" appointment at an Apple Store, or go to another authorized service provider.
If nothing is wrong with the hardware, then whatever you can do to improve cooling may help.
Installed software
User-installed software that includes a device driver or other kernel code may thrash the kernel. That category includes virtualization software, such as Parallels and VMware, as well as most commercial "anti-virus" products. Some system-monitoring applications, such as "iStat," can also contribute to the problem. You can test for this possibility by completely disabling or removing the software according to the developer's instructions, or starting in safe mode. Note, however, that disabling a system modification without removing it or testing in safe mode may not be as easy as you think.
Corrupt NVRAM or SMC data
Sometimes the problem is cleared up by resetting the NVRAM or the SMC.
External display
Connecting an external LCD display to some MacBook Pro models while the lid is open may cause this issue. If applicable, test by closing the lid or disconnecting the display. You might get better results with a newer LED display.

MPC800K usb and fan power control problem.

Hello all,
I own one of these MPC800K (K8M800 Via chipset...) boxes for one week now and since the first day I've always been surprised because both system and cpu fans were stuck to approx. 2100 rpm, whatever the cpu was doing. (Burning or not). It was a little noisy to my taste when just playing mp3 by exemple, so I tried yesterday to flash the mobo with what seemed to be the latest bios available. The board is reporting to be MS-7056, but when I browse MSI support pages, I can see that MPC800K is sometimes claimed to have 7056 or 6276 model motherboard. Confusing. When downloading bios, reference is made to 6276 mb on the download page, then inside the archive, bios file name is "A7056VMS.320". Even more confusing, but I made the choice to believe 7056 and 6276 are the same. (Can anyone confirm...?).
Flashing bios from one usb key ran perfectly, reboot ran perfectly, so did loading Windows (Home Edition). Oh, nice, it seemed to be my day of luck, because favor to this new bios (version 3.20, was running 3.13 before), cpu and system fans were now much more quiet when the cpu was not heavily loaded. Good. I love silence. Eh, but wait ! What the h... Where does come from this slight but really annoying hissing sound ? Seems to come from the inside of the box... You know, the kind of tipicaly electronical hissing sound, when some composant is subjet to some kind of stress. Then I noticed that the integrated card readers activity led was turned on but there wasn't even any card inserted. Abnormal. Trying to reboot. Ah, good. Led is now turned off. But there's still this annoying hissing sound, and... oh no, cpu and system fans are not quiet anymore, they went back to medium speed... Always.
Let's think. ... Let's try something. Shuting down windows, going to the bios, disabling USB integrated controler (because of the fancy behavior of the card readers led, obviously related to some kind of usb disorder, don't you think ?). Rebooting. Nice ! No more hissing sound, and fans control is now effective. Of course the bad news is that having disabled usb, I've no more usb ports working. Unfortunately, I need them.
Going back to the bios, re-enabling usb support, going back to windows, and playing with usb host controler in the device manager -> As soon as it is disabled, fan control is working perfectly. As soon as I re-enable it, automatic fan control is out of order again.
The choice is :
- functionnal USB ports but electronical hissing noises and no fan control
or
- fan control, no hissing noises, but no usb either.
Oh yes, I could always come back the old v3.13 bios. USB would be functionnal but I would lose automatic fan control and I would get rid of the hissing noises.
But :
1/ I would like to have fan control working !!!
2/ I did something I should not have done. (Guess what, I did not dump my old bios prior to flashing the new one, and there is absolutely no archive around the whole "googled" web.)
I also tried to install another version of windows to see how it would handle the situation. Well... I installed W2003 Server, and it's nearly the same mess : no fan control and hissing noise when usb enabled, but effective fan control and no more hissing noise when I disable "Standard enhanced PCI to USB Host Controler", and then a little surprise : usb ports are still working, but I lose 2.0 high speed, everything is falling to 1.1 full speed. (With XP Home, I had to disable VIA enhanced USB host controler, and then all usb support was off).
I think it's likely to be some kind of conflict between usb controler ressources and the way the mobo control the fans. Adress conflict, irq conflict ? I don't see how I could test since the bios doesn't let me change them in any way.
If someone has any idea to let me escape this bad situation, I would be *grateful*.
Maybe another release of the bios could help me ?

^
hmm, I have never hear of a USB controller making a hissing noise????
anyway try keeping usb controller enabled and disconnect the usb card reader. there should be a little cable that will enable you to disconnect the card reader. do you get a hissing noise with it disconnected?
eitherway I would think about return the system for another one. or warranty

PowerMac G5 Dual 2.5 - Only Boots with Side Cover and Fan Guard OFF!!

I have the strangest problem with my PowerMac G5 Dual 2.5. This has been my Pro Tools rig forEVER.
At some point early last year, my Mac wouldn't boot. It would not see the hard drive, and would show that dreaded alternating icon in the middle of the screen indicating as much. I tried resetting, tried power off/on, tried resetting PRAM. Nothing. I took the cover off, and fan guard off to get at the hard drive. Verified the data and power cable were seated in hard drive. Cover still off, I booted up the system. Voila!!! Booted right up like nothing was ever wrong. I put the cover back on, and went about my business, passing it off as a one-off power glitch (the power in my house ***** rocks). Next time I rebooted the Mac, the exact same thing happened.
I can repeat this at will. If I leave the cover on, the system will not ever, ever boot. The minute I take the cover and fan guard off, causing the fans to spin at max speed when turned on, the system boots without issue. So, I reset PRAM and PMU. I even tried replacing that green/white cylindrical battery on the motherboard. Reseated power/data cable on hard drive. ****, I even tried a different hard drive and memory (explained below). No change.
Since then, I have relegated this system to the emergency backup system, and procured Dual 2.7 G5 PowerMac. I transferred the pro tools cards, hard drive (without formatting it) and memory (8 GB) to this new 2.7, and have not had a single, solitary issue with it. So, I know it's not the hard drive, memory, OS install, or Pro Tools cards.
What in the name of the Apple Gods could be causing this issue? Any ideas at all?

Hi Chris,
Good info & work so far, but indeed strange, only thing I can think of is something to do with that little switch for the fan cover... near the bottom as I recall, but it may be some kind of short in it's circuit.

Will not boot up and fans run at high speed

will not boot up and fans run at high speed

after much head scratching I ran the hardware test disk from cd. The test showed a memory issue I eliminated the faulty one systematically. So it wasn't a hard drive or software problem in the end it was faulty memory. What was misleading was the computer telling me there was a fault on the hard drive. The machine works fine now. Thanks to people's comments I learned a bit more about the G5 that helped eliminate probable causes

MDD and Fans Blazing

I have a MDD Dual 1.25 with the original 400 watt power supply and fans. This machine used to sit in a server room so the noise it made did not create a problem. It was recently retired from it's position and now will become a desktop for small to medium tasks. The problem is since I reformatted the hard disk and installed Tiger, the lower fan starts increasing it's speed about 60 seconds after the machine is turned on and booted. I installed Temperature Monitor to see if it would reveal anything. According to Temperature Monitor, the breaking point for fan speed is 62C. Once the computer's temperature reaches above 62C, the fans start to rev up. The fans in this unit rev up and up and up and up but the temperature finally settles at around 68C.
The other 2 MDD's in our office run comfortably around 54C, but they had the power supply replacement recall done.
Is the power supply somehow related to the CPU temperature sensor? I decided to replace the variable speed lower fan with a 3 speed fan that is quieter. The computer will only run for about 4 minutes before the goes to sleep because of the CPU overtemp sensor. The heat sink is barely warm. I tried resetting the CUDA chip but that does not see to make a difference.
Any Suggestions?

I'm sure you have already cleaned the case and heat sink, but just a reminder. Also check the orientation of the fan. I think it is possible to install the OEM fan in reverse so that it ***** over the heat sink instead of blowing. Also try removing the heat sink, remove the OEM heat tape (the black crap) and apply a thin coat of good paste (I'm sure Arctic Silver will be recommended by someone). I get better results after 2-5 heat cycles.
My MDD ran about 58 to 62 with the aluminum heat sink. I got hold of a copper one from a 1.42 and now it runs 54 to 58 (and that's overclocked to 1.33).
Lastly consider case mods such as a stepper fan in the 3/4 drive bay.

Early 2008 MacBookPro keyboard backlight off and fans run at high speed

Hi!
I wrote from Turkey.
My Early 2008 MacBookPro 2.40 ghz 4 gb Ram OSX Mavericks machine's keyboard backlight off and fans run at high speed; it seems an exact smc resetting problem.
So i tried the 2 ways of SMC restting procedure; both battery you can move and not, but nothings changed on the situation..
On the way for removable battery; nothing changed but on the way for umremovable battery way; keyboard backlight flashes and gone, but fans are at high speed not changed. So nothing changed.
What can i do right now? i'll wait for your advices
Thanks

Your Mac may need a new PRAM battery. Once it is over 4 years old, that often is needed.

Satellite M70: accessing data of temperature and fan

While we hadn't such problems with other laptops, we didn't find a way of accessing the data of temperature and fan on a Satellite M70.
A friend tried this under Linux but didn't succeed and also with XP I don't find a way of reading the data (current temperature of CPU or state of fan-cooler).
Since I notice several irregularities while operating (fan is working though cpu-load is very minimal), working is sometimes going to be a bit uncomfortable.
thanx for hints / gw

I dont know if it will help you but in this posting someone has managed to run a hardware monitoring application.
http://forums.computers.toshiba-europe.com/forums/thread.jspa?threadID=14284
Possibly it will work on your notebook.
But in my knowledge Toshiba doesnt support such application and Im not sure it it will work.
Anyway, trying is for free ;)

Monitoring 3750x and 3560x Redundant Power Supply and Fans

I need help for monitoring the redundant power supply of my switches (3750x and 3560x)
I have configured my snmp on my switches and is able to monitor interfaces, temperature and etc.
The problem is when I am monitoring the redundant power supply and fans.
I am using two Cisco C3KX-PWR-350WAC Modular Power Supply per switch.
The OID I use to monitor the PSU are the following:
Power Supply 1
.1.3.6.1.4.1.9.9.13.1.5.1.3 Instance: 1003
Power Supply 2
.1.3.6.1.4.1.9.9.13.1.5.1.3 Instance: 1004
When I do an SNMP walk, the value is showing (1) which means normal.
When I simulate a power outage on power supply 1 or 2 by unplugging the power source, the value doesn't change and is still (1).
Values: normal(1), warning(2), critical(3), shutdown(4), notPresent(5)
As for the Fans:
When I remove the fan module, I am able to get a notification that the fans are down, but when I plug back the fan module it is now using a different instance.
Below is my config for SNMP:
snmp-server community XXXXXXXXXXXXXX RO
snmp-server location XXXXXX
snmp-server contact XXXXXX
snmp-server chassis-id Cisco3560X
snmp-server enable traps snmp authentication linkdown linkup coldstart warmstart
snmp-server enable traps transceiver all
snmp-server enable traps tty
snmp-server enable traps license
snmp-server enable traps cpu threshold
snmp-server enable traps syslog
snmp-server enable traps vlancreate
snmp-server enable traps vlandelete
snmp-server enable traps port-security
snmp-server enable traps envmon fan shutdown supply temperature status
snmp-server enable traps errdisable
snmp-server enable traps vlan-membership
snmp-server host X.X.X.X version 2c XXXXXXXXXXXXXX
Note: This problem is the same for all of my 3560X switches and 3750X switches. I am not sure if I am monitoring the wrong OID.
Thanks in advance

Hi ,
You are running an old IOS code , definitely you are hitting a BUG .
there is no workaround or I would say unfirtunetely you will not be able to get the correct power supply status via SNMP.
you need to use command line for this.
I mean "show env all "
**** if you want to know the Excat BUG that your code is hitting ,please contact TAC.
Thanks-
Afroz

Macbook pro heats up and fans go crazy as soon as I plug in charger, SMC reset doesnt help

Hi all, my problem is that my 2011 MBP heats up and fans speed up (a lot) as soon as I plug the charger in. There's no other apparent reason. No heavy CPU usage at all, SMC reset did nothing at all. It only started recently and it goes away as soon as I plug the charger out. Laptop also has an SSD fitted into it. Someone please help, thanks

sorted...
