Fans speed up with video use

2006macbook pro fans go full speed with video use

Sure, heavy use of the graphics chipset and the cpu generate a lot of heat, so the fans ramp up. As long as the machine is working properly, then that is exactly what is supposed to happen as the system automatically deals with the increased heat load.

Windows 7 - Possible to adjust fan speed UP with "official" tool?

I just got a new T500 with the switchable graphics option, and windows 7 Pro x64 installed.
When playing a game like TF2(i.e. maxing out the ATI discrete card), the system gets fairly hot - Not critically, but the rear-left corner of the system gets hot enough to be annoying against my leg.
As such, I'm looking for a way to increase the fan speed at higher temps - when I'm gaming, I don't really care about noise; I either have loud sounds happening or headphones.
Is there any more-or-less official solution to do what I want, or do I have to resort to an unofficial tool like [url=http://www.thinkwiki.org/wiki/How_to_control_fan_speed#For_Windows]This[/url] one?
Thanks,
-Robbie

so you are using the laptop on your leg? there is no official tool as such for setting the fan speed at certain level, as it is regulated by the computer thermal management circuitry as needed.
However, i highly suggest you try to use a laptop cooler, and don't use the laptop on your leg when playing games, as prolonged usage could cause first degree burn to your skin. This is why some laptops are called notebook and carries a warning against using the laptop on your lap.

Minumum fan speed increase with leopard?

I have searched the forum a bit but can't find anything about this.
After installing Leopard I have noticed that I can always hear my fans spinning. I use smcfancontrol. In Tiger I had the minimum set to 2000rpm when nothing intensive was running. Now with Leopard I can't set the minimum lower than 3000rpm. Does anyone else have this problem?
I prefer not to hear the fans unless they are needed and 2000rpm's was almost silent but 3000rpm's is not.
I have reinstalled smc twice and even when I disable it, istat says the fans are running at 3000rpm's. Is this the new MBP minimum for Leopard?

Ok, before it just looked like there was one post. I bought a brand new macbook on Friday, which of course comes with Leopard. Judging from these posts, it sounds like this may be an OS problem and not hardware.
Activity Monitor sometimes shows runaway processes, as others have mentioned. Right now there is something called syslogd taking 100% and the fan speed is 6208 rpm. When I kill it the fan slows down but then it comes back. The fan will run and be noisy even when I'm not doing anything. Right now it says the temp is 34 degrees. I don't know what the target temperature is, so I don't know if it's an issue of running hot or of running the fan more than it needs to. When I called the Apple Care line yesterday it was going to be a 15 minute wait so I didn't hold, but I think I'll try and do it tomorrow. If I get any good advice I'll pass it on. I'll try to see if the fan ever runs fast when nothing is sucking up CPU or only when I get the runaway processes.

Is it possible to control CPU fan speed (lower) with K8T NEO2-FIS2R (MS-6702)?

I have:
MSI K8T NEO2-F motherboard
AMD Athlon 64 3000+ processor
Bios is latest I found, AMI BIOS 9.20
Operating system is Windows XP pro.
Processor was boxed and with the normal amd fan.
Processor fan is plugged in CFAN slot.
My problem is that the cpu fan spins a bit too fast. Cpu temp stays at 25C and fan is spinning at 1800 rpm.
Setting manual mode from corecenter didn't change the fan speed at all. Not up or down. Neither can SpeedFan program. But if I stress the cpu, the fan starts spinning faster.
What is controlling the fan speed and can I manually control it?
There are no control options in bios.
If I missed any information, please do ask more.

Hi,
Core Center is crap, you can't do anything else with that than uninstall.
Speedfan works. You'll have to set "PWM 2" from "thermal cruise" to "manual control" somewhere in the advanced configuration menu, I don't remember where you can find that. The help file provided with speedfan is quite good, I strongly recommend reading it carefully. Using speedfan you can also control a second fan connected to the SFAN-connectors.
The built-in fan control sets the speed of the CPU fan to 2/3 of its nominal RPM value (my fan starts at 2100/min, max is something about 3300/min or so). Its speed increases quite late, on my system at temperatures above 50°C. And it increases quite slowly.

Ipod with video use firewire ?

I have just got an Ipod with with video and wondered if I could use firewire instead. My old Imac G4 only has usb 1.0 and is too slow and the ipod doesn't seem to update or just makes Itunes hang while copying a song across. Any answers would be helpful.Thanks Peter.

Hi thanks for the reply - suppose I will have to buy a new imac then !

Bad noise/ fan speed problem with Rev B iMac

Like a lot of other people, I'm having problems with ridiculous fan noise. I've read through the forum and tried the following (with no success):
1) Reset SMU (x2)
2) Ran Maintenance Scripts. (x2)
3) Removed the back and blew dust from fans, ports, etc.
The processor is set to automatic. The problem occurs whether or not I have any peripherals plugged in. I get the noise/rpms when all I have running is Safari and XRG.
On certain websites, the CPU fan will climb to 5600, CPU temp to 79C, with CPU usage at 80-90%.
Does this sound like a logic board problem? Something else, possibly?
Basically, I'm trying to cover all of my bases before I get on the phone with AppleCare. I'd like to try to keep that as short as possible. Thanks in advance for any help/comments.
iMac G5 (ALS) 17" 2.0GHz 512MB RAM Superdrive Mac OS X (10.4.8)
iMac G5 (ALS) 17" 2.0GHz 512MB RAM Superdrive Mac OS X (10.4.8)

Just an FYI. During my iMacs motherboard replacements (3) I was never asked for a case number once. I spent hours on the phone with Applecare when in reality I already new I had a hardware problem and if I would have just taken it in it would have been fixed quicker. The third time I took my iMac G5 in for service the local tech told me to call up Applecare (3rd time then call) and ask for a replacement stating that if they need to call me he would explain that I had a lemon. In everyone of the three bad motherboards the fans spun out of control so I have more experience than I would prefer on this subject. They did step up and as you can see in my profile I have a new Intel iMac courtesy of Apple.
Also a utility to measure your fan speeds is here: http://www.gauchosoft.com/Software/X%20Resource%20Graph/

NB fan speed adjust with CoreCenter

Looks like it isn't possible to adjust NB fan speed with latest CoreCenter on a 865PE Neo2 with latest Bios.
CPU fan speed adjust works great.
Any help?

I've just tested Speedfan and this Program doesn't work also (and YES i've read the complete guide).
Is it a problem with the latest Bios 3.6?

Fan speed increased with Leopard

Just upgraded to Leopard and 10.5.1. The fan speed on the iMac G5 has now jumped by about 50%. Way too loud for office. What may be the issue and how do I resolve it? Fan speed is increased all the time, not just when it would increase under Tiger.

Hey Jack
You can open the Activity Monitor in the Utilities folder, hit Command - 1 (apple + 1).
At the top of the window, select ALL Processes, and then sort by CPU so that the largest numbers are at the top.
See if there is something hanging everything up. It could be part of an application that doesn't run well in 10.5.
I did a re-start once on a G5 and had a similar problem... big fan noise... but when I re-booted it, it went away.
The fan increases with processor load, so try to find what is taxing your processor.

Audio not sync with video using photo booth since os moutain lion was installed

Since OS Moutain Lion was installed my photo booth no longer function well, audio is not sync with video, the sound delay is obvious with the video outut wha can I do to correct this?

I've seen that problem in several threads, both here and in the Mountain Lion forum. I tried to replicate the problem but was unable to do so... so it's not a problem effecting all Macs. Try posting here - in the Mountain Lion forum - and see what you get as a search. There's one specific "More Like This" to the right on this thread but there doesn't seem to have been a solution posted.
Good luck,

Help with Video use in Sarfari

Hi I posted about not being able to access Fox Videos with Safari but am able to with Firefox. Was told to remove any Flash Players present and update to the latest and do re-Permissions settings, which I did, but NO JOY! Still NOT able to access Fox Videos, but can access other Networks videos.
PLEASE I need to know what the problem is with SAFARI as its obviously not a Flash Player problem.
Would an older version of Flash Player on my 'Parallels Desktop' also affect playing the New Latest Flash Player in Safari even though I am Not in Parallels? Just a thought?
If no answer or ability to resolve this problem I simply will cease using Safari altogether as its obviously an inferior platform for Videos and use only Firefox.
Thanks!

HI,
Would an older version of Flash Player on my 'Parallels Desktop' also affect playing the New Latest Flash Player in Safari even though I am Not in Parallels? Just a thought?
Since it's not interfering with Firefox, I doubt it.
Install the v10.5.8 Combo Update
And go to ~/Library/Caches/com.apple.Safari and move the "cache.db" file to the Trash.
Relaunch Safari.

I have no sound with videos, using Firefox youTube, etc.) With Google Chrome, I get the sound. Why?

When I try to play a video on Firefox. The movie plays, but there's no sound. I checked ALL of the computer settings, and video settings. If I switch to Google Chrome, and play the same video, I get terrific sound. This switch is done without modifying ANY of the controls....just switching browsers. Why no sound?

Hi TommyB,
It could be a couple of things. You might have accidentally muted audio for Firefox. The article Knowledge Base article [[No sound in Firefox]] will show you how to check.
If that doesn't work, you should look at [[Video or audio does not play]]. This will show you how to troubleshoot any plugin/extension issues that might be impacting your system.
Hopefully this helps!

NX7600GT Diamond Plus and fan speed with Dual Core Center

I just got a NX 7600GT Diamond Plus for my HTPC. I noted that Riva Tuner and other utilities are not able to control the fan speed of the video card. The only way one can control the fan speed is via Dual Core Center and 3D Core Cell. The problem is that the default setting for fan speed on Dual Core Center is too high and clearly audible. How can I get Dual Core Center to start with user defined presets during windows start-up/boot-up ?
What I want to do is to put the fan into 'SILENT' mode automatically during Dual Core Center start-up. Any ideas / suggestions ?

Quote from: BOSSKILLER on 17-January-07, 00:44:11
well no need to edit manually, MSI provided everythink in easy way from core center.
select advanced mode, create your custom profile pickup your desired settings,(setup maximum FAN RPM via buttons) and save it to custom profile.
suggest you to read help section from program.
So the custom profile is automatically loaded every time DualCoreCenter starts up ? Maybe there is something wrong with my install of DCC, I cannot get it to load custom profiles automatically upon startup. I can save the changes to say "User Profile 1" but the profile active on startup always is the "default" profile ...

Fan speed problem Power Mac G5 Dual 1.8 GHz PowerPC - please help

Please HELP, I have a fan speed problem with my Power Mac G5 Dual 1.8 GHz PowerPC
This is a NOT an Intel machine. I am running Mac OS X v10.5.8
Power Mac G5 - PowerMac 7,2 - Power PC 970 (2.2) - 1.8 GHz with 2 CPUs - L2 Cache (per CPU) 512 KB - Memory 8 GB - Bus Speed 900 MHz - Boot ROM version 5.1.5b1
I have included below Links to download a sound file (.m4a) that I recorded of the fan speed problem and both a .pdf and .spx files of my system profile.

When did the fan problem start?
After I replaced the mother board on the computer.
Why did I replace the mother board?
Because the experts at apple agreed with my diagnosis that the major crash problems & kernel panics must have some thing to do with a logic board gone bad. They would not work on it, because this Power Mac G5 dual 1.8 GHz machine is now a legacy model.
What I have done to attempt to fix my fan speed problem? yes I checked the obvious things, here is a list:
1) yes I checked to be sure that the new mother board was the same part number as the original one, and that all things that were unplugged from the old mother board - were actually plugged into the new mother board.
2) all the fans work, I can see them spinning if I use a flashlight and look at them (cover on and off to get at some of them)
3) check all RAM to make sure: a) it was installed properly b) that the RAM worked using TechTool Pro c) even started the machine with only the original RAM that came with it.
4) I installed a Temperature monitor - to see if there was something reading as very hot inside that was causing the machine to continually run the fans at a high speed. No, no heat issues that I can see. Here are the reading from the sensors in degrees fahrenheit, 2009-10-11 16:11:01 -0500
CPU A Die Temperature: 75.7℉
CPU B Die Temperature: 81.5℉
Drive Bay: 68.9℉
Main Logic Board Air Inlet: 64.8℉
Main Logic Board Ambient: 73.6℉
Main Logic Board Backside: 76.3℉
Memory Controller Heatsink: 93.2℉
Processor Card A Ambient: 77.5℉
Processor Card B Ambient: 77.0℉
5) zapped the PRAM
6) followed the SMU reset instructions for
Power Mac G5 (Late 2004)
To reset the SMU on a Power Mac G5 (Late 2004) computer, simply do the following:
• Turn off the computer by selecting Shut Down from the Apple menu or by holding the power button until the computer turns off.
• Remove the power cord from the computer.
• Wait two minutes.
• Plug in the power cord.
• Turn on the computer.
7) followed the SMU reset instructions:
Resetting the Cuda/PMU
How to reset the PMU:
• If the computer is on, turn it off.
• Disconnect ALL cables from the computer, including peripherals and power.
• If possible, move the computer to a place where you are not standing on carpet.
• Open the case and ground yourself by touching part of the metal frame inside the computer.
• Find the Cuda or PMU button
• Press the Cuda or PMU button ONCE. Do not press the button more than once before starting the computer up again.
• Wait 10 seconds, then reconnect the cables you removed in step 2 and turn the computer on.
• If the computer still does not respond after resetting the PMU, the computer may require service from an Apple Authorized Service Provider.
8) ran disk utilities, repaired permissions
9) found a setting in the system preferences that a chat room person suggested had something to do with fan speed. In Energy Saver, under options, processor performance was set to highest, I set it to automatic - this did not change anything that I could tell - BTW I checked my other G5 (a single processor that works fine) that is the setting that that it is set to, and it is nice and quiet.
10) restarted the machine, ..
11) found a Fan Control System Update - but it did not install when I tryed to install it -
12) booted from OSX install disk and ran that disk utility
13) used OnyX to fix disk permissions, clear caches and temp items
Nope - still have the same high speed fan problem. ... PLEASE HELP!!
I have been reading in the MacInTouch reader reports - found this: some one said to use this - thermal re-calibration using the Apple Authorized Service Providers' disk - but that's not available, at least I can not find it - anyone? have an answer to finding this - or can do it for me? I am in Chicago.

The Genius at the downtown apple store said that because it's a "legacy machine" they would not work on it, .. so should I push them?
Well, I personally think that's ridiculous, I'd Push them, I'd call AppleCare & talk up the chain if need be... there the ones that have or should have that Disc... man o man... Personally I'll never visit an Apple Store again in my lifetime, maybe try an independent AASP if none of that helps!..

Man-o-man, pop my cork before I explode on that one, if I had anything to do with it I'd close that store.

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?

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.
