CPU heats up on file copy/backup and fan speed does not increase

Hi Friends,
I have been having issues with fan in my Dell Studio 1555. It has an ATI Radeon card and I had installed the proprietary catalyst driver as the open source driver is too noisy.
Recently, I noticed that on accessing my hard disk and copy files or running backup (luckybackup), the temperature shoots up from around 60 deg C (just using chrome) to 100 deg C when it would shut down itself. However, it seems like the fan speed does not increase with the increase in temperature to help it cool down.
I tried to get the fan speed details with "lm-sensors" but it would not show the fan speed. Here is the output of sensors:
[user@domain]$ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1: +60.0°C (crit = +100.0°C)
temp2: +59.0°C (crit = +100.0°C)
temp3: +66.0°C (crit = +100.0°C)
coretemp-isa-0000
Adapter: ISA adapter
Core 0: +58.0°C (high = +105.0°C, crit = +105.0°C)
Core 1: +58.0°C (high = +105.0°C, crit = +105.0°C)
Following the Arch wiki, I added acpi_enforce_resources=lax to kernel parameters but it did not help as well.
Here is the main problem:
1. CPU temperature shoots on accessing hard drive but fan speed does not increase - Any guide/direction to investigate would be really helpful.
2. Sensors does not show the fan speed. Read about i8kutils, but couldn't figure out how to get it working with systemd. Any indicators here?

Im having similar issue on a vostro 1710, fan never works... :-/
The fan was bad. I had to replace the fan. However, I have not been able to figure out how to see fan speed in sensors.

MB990 and SL - Fan speed is not increasing automatically

Hi Guys,
Two days ago I changed my macbook's hard drive to a bigger one and did a fresh install of Snow Leopard.
As soon as I installed the SL I noticed my computer was running hotter than the previous installation. Without doing anything, my macbook is reaching 75C (167F).. I have already checked the activity monitor and no process is using the CPU. Now I realized that the fan speed is not increasing automatically, it is always fixed at 2000rpm even if the temperature reaches 72C.. I have already tried a SMC reset but the problem persists..
Does anyone know a solution for this? The problem is the fan speed that is not increasing..
I'm having to use smcFanControl to control de fan speed manually. Before the fresh install I was using Snow Leopard updated from the Leopard and I was not facing this problem.
Thanks a lot!

Hi there... i have the same problem. my temperature gets up to 75C with just one window open in safari or google chrome. I have downloaded smc Fancontrol but ...its not enough. have u solved this problem yet? i'm going in to the Genius Bar tomorrow to see if they can help.

I delete files but my available disk space does not increase

I delete files but my available disk space does not increase. What to do?

Try reindexing the hard drive:

HT4946 i want to backup my iPhone to my new iMac but my backup is selected to Encrypt Local backup and my password does not work.

I am trying to backup my iPhone on my new iMac iTunes. It is currently backed up on my PC and encrypted. Both PC and iMac iTunes have Encrypted backup selected. My password does not work for either iMac or PC. Should I go ahead and try to backup to my iMac iTunes.

Sorry to hear about your phone jb111jb! We'll do everything we can to help find the best route! The only way to remove the password is flashing the device, but that will erase all the content. Have you ever backed up using Verizon Cloud or Google Sync? Do you have a memory card?

Backup and Recovery Tool does not record backup

When I run the Backup and Recovery Tool backup on my OAS mid-tier (Portal/BI), the backup fails because it is unable to start the wireless service, which I am not using.
This would not be a big deal, except the Tool does not record the backup, so I cannot select it to restore.
Is there a way to force the Tools to recognize these backups or stop the Tools from attempting to start the wireless component?

dmctl have an option to backup the configuration only, I dont remember if that's available for that version,but you can check running dcmctl command without parameters, it would show a big list.
If dont, best way is making a cold backup, stop all process, make backup and start process. Remember to start proceses using dcmctl command, not opmnctl.
Greetings.

T430s fan noise and fan speed monitor not working?

Hi, I just bought this T430s from the outlet store. I noticed a rather loud fan noise and found out s lot of compalints about the T430 model. I guess the problem I have is not as severe as those T430 users (e.g. the noise may not be as loud), but I still want to monitor the fan speed. Here's my problem:
1. none of the third party software can show fan speed, they can only show the cpu temperature, such as speedfan and aida64.
2. I tried to download the fanspeedcontrol driver from lenovo, but after installing it, the task manager does not show that the fanspeedcontrol exe. is working.
I do not want to change the fan speed, but just want to monitor the speed so that I can have a better understanding of whats going on. Does anyone have the similar problem?
Thanks.

Hi Alan, (I know this conversation was from several months back),
I don't know the answer to your questions. It seems that your fan is operational, as far as its most basic functional requirement.
I don't have experience with any particular software programs or widgets that indicate fan speed, sorry.
Do you have any view, through software, of the CPU (and GPU?) sensed temperature? Those would be very good data to observe.
If it were either disconnected or non-functional, I assume that your computer would report a POST error right after power-on (and self test).
But I just wanted to suggest here that in an unfortunate possible scenario, consider if the thermal grease on the heat sink(s) was inadequate (or was missing), then the fan would be running higher than normal (probably always spinning at a high rate), and it won't be taking enough heat away from the processor(s), i.e. inadequate cooling.
Which could be corrected by a technician (or DIY). This is pure speculation, it is not a definite, at all.

In the download box, the check box for "always do this for this type of file" is grayed out for the type of file I want, and that application does not appear in the application menu, so how do I set it to perform this function every time?

The file type in question is InCopy, and the download box acknowledges that program as the type to open it with, but I never want to open it; I always want to save it. This feature works fine with other file types, but not with InCopy. I download thousands of files, so automating this is very important.

The copy, copy image and save as does not work for pictures in release 10.0.2. saves blanks.

just put release 10.0.2 up at work and it was automatically put up at home and it won't copy pictures using copy or save as.

First Backup on Time Machine - CPU temperature and fan speed

I attached my external WD drive and started Time Machine. Works just fine however I watched the cpu and temp and fan speed as reported by iStat.
During the hour long "first backup" I reached an incredible 160 degrees cpu temp and 6000 rpm fan speed. Cpu was 70 percent or so. When this temp was reached it looked like some limiter took over to reduce cpu consumption and temp. CPU dropped to 30 percent and the temp came down. Fan rpms reduced as temp did.
I don't know if iStat reports the feeds on a MacBook Air properly or not but if so......interesting.

160F is not very high - 160C would be a different matter.
Under sustained 100% load, my Macbook CPU is at about 190F, with the fan at about 6200 rpm, in a room at about 68F.

USB/FireWire usage increases CPU temp and fan speed

Hi,
I'm curious, does the usage of USB and FireWire ports increase CPU temperature and fan speed...?
I have an M-Audio Fast Track USB interface plugged in and whenever I play any songs from iTunes using that interface as an output, my CPU temp increased and fan speed jumped from 2000 to 3300 rpm. And on separate occasion, an 8GB of file transfer from an external FireWire-based HDD had both fans speed up to 4,400 rpm.
Is this normal...? All these were done with an external display plugged onto the MBP with "clamshell" mode.

USB operations involves quite a bit of CPU action, Elphidieus.
Firewire places less demand on the CPU but, in a situation like the one you describe can involve both increases in power usage and in HD temperatures.
The fan speeds on Macs are not simply responsive to CPU usage. Both HD temps and power usage can also play a part in the equation that ultimately produces the fan speed. As HDs have much lower heat tolerance than CPUs you will find that it is quite common to see the fans ramp up when doing a large file transfer over FW (or USB, for that matter) , especially if the internal HD temp gets to over about 50-55º Celsius.

Most likely you have Office 2004 which are PPC-only applications and will not work in Lion. Upgrade to Office 2011. Other alternatives are:
Apple's iWork suite (Pages, Numbers, and Keynote.)
Open Office (Office 2007-like suite compatible with OS X.)
NeoOffice (similar to Open Office.)
LibreOffice (a new direction for the Open Office suite.)

Under Snow Leopard I used a WD My World NAS to back up my Mac Pro (Mid 2010). When I upgraded to Lion I am unable to access the backup because the NAS does not yet support AFP. I have now bought a Time Capsule and want to transfer the old backup onto it.

How can I recover the NAS back up to put on my new Time Machine.
Talking to Apple Support Adviser was a waste of time on case number 239647273
Any thoughts or pointers?

Keep the old OS around and just kick the tires and test new OS. Apple has a history and habit of breaking support in things like this.
You can use TimeMachine as one level of backup, and even there there were changes with Lion, I would always recommend foremost backup clones of every volume. And clone (SuperDuper etc) can be stored on something like HP NAS Media Server which also was supporting TimeMachine, iTunes - until Apple made that harder and more their own proprietary format.

Cloning as a Backup Strategy
Rather than "upgrade" I would clone the system, and do a clean install, then allow Setup Assistant to import your files.

Hi
My imac is 27 inch mid 2011
after i use my imac for 30 min, the machine is getting really hot on top. It happens fast if i play game like Leauge og legends in windows bootcamp, but it also gets really warm when i just surf on safari/internet. So no matter what i do, as long as i use imac, it gets really warm. Can anyone tell me why it gets hot? and sometimes fan make really loud noise, like imac is going to explode or melt itself. But my imac have never shutted down caz overheat.
Here's info of my imac:

Whats the normal temperature and fan speed?
And whats the reason to this heat issue?
How can i solve this?

My imac is on the table in the livingroom. So its not very hot in this room. Only reason of heat is the summer… but this heat problem has been since before winter…
do u have any tips or suggestion what i should do to solve this?
I dont want my imac to burn or melt inside
