Qosimo X775-3DV78 - Fan no longer speeds up

My lap top shut off not too long ago and now I noticed the fan no longer speeds up.
Only the usual fan air take works but not the loud fan that speeds up.
I fear, the laptop will only burn out eventually, any help?

The laptop will shut down if it gets too hot before damage occurs. However, if the fan has failed, you'd probably want to have your laptop serviced.

IMac G5 (no iSight) fans running full speed always

Hi,
The processor usage is relatively low (like 10%) but the fans are full speed at all times from the second the power comes on. I imagine there isa problem with the mother board? I've tried resetting all the SMC stuff, no effect.
Any ideas?
Is this something Apple Stores will charge to fix?
Thanks

It could be either faulty, leaking caps, or a failing power supply unit. Yes, Apple will charge since you are long out of warranty. You can open the machine and check the caps yourself, they look like little soda cans, and their tops should be perfectly flat and there should be no exudate.
Let us know what you find,

Spinning beach ball of death after crash with fans running full speed

I recently put my machine to sleep - came in the next morning to find it running all fans at full speed and frozen. Did a hard reset (power button in for 5 seconds waited 15 secs and then power on. It rebooted after a long re-boot period. Since then it has slowed down. Many apps take an age to open. Many freeze and there is the infamous SBoD. I have rebuilt permissions, installed 10.5.8 combo, done a permission repair from a separate firewire disk, run onyx - which at time never ends and has to be aborted. Activity monitor shows no exceptional activity when the SBoD is running. I had significant issues until last December when i did a clean rebuild and installation of leopard and put all essential software in from clean install disks - all in all had a pristine machine which was working perfectly until the week before last when the full fan and freeze crash occurred. I notice that it speeded up after the 10.5.8 combo install and permission rebuild from external disk but gradually slows down and gets increasingly unstable requiring forced reboots more and more often. I have no hacks or other background processes other than Virus Barrier 6 which ran perfectly before the crash.

As expected after running well at about 11:40 Mail slowed down and the SBoD started.

IMac Overheats & Fans Won't Speed up to Cool

I have a 2007 iMac that for some reason the fans won't speed up above idle and so if it's put to heavy use eventually it will overheat and shutdown. It was a while before I had installed software that measured temperatures of devices or fan speeds inside the iMac and then determine what was happening and that indeed the iMac would shut off when the power supply got too hot.
Then I found some of these apps that let you control the fan speed manually or customize the threshold and with some of these I was able to speed the fans up. The one I chose as the best was Derman's version of Fan Control, a control panel which is automatic and effectively keeps all the temperatures normal and has been my solution to the problem. Many people seem to like SmcFanControl for some reason but I don't because it's crude and totally manual in setting the base fan speed which keeps the fan running higher than normal all the time but doesn't help much to cool if the iMac gets really hot unless you manually speed up the fan more.
The whole thing baffles me. Why can this control panel speed up and control the fans just fine and effectively cool the iMac but left to it's default control it does nothing and allows the iMac to overheat? And has anyone had this problem and found a way to fix it?

As you have already noted, the problem with SMCFanControl is that it only sets a higher minimum speed which leaves the user to have to manually ramp it up (or define a higher preset for various level tasks) when running something that will tax the CPU. Cooler idle speeds will do little to extend the life of your computer. My new Quad-Core i7 Mac Mini idles at a cool 110-115 degrees Fahrenheit (yes, that is COOL in computer terms to those that think it's hot because a day in Arizona at that temperature feels very hot).
Manual control is better than nothing if you know you're going to play a game or encode a file, but it stinks if you have a batch of files and you leave the room and it finishes and your fan keeps needlessly running at higher speeds (possibly for days if you left on a trip and left a list of videos to convert while you're gone). I've left feedback on SMCFan's web site, but perhaps having an upper limit is beyond the author's capability?
Derman's Fan Control has exactly the features needed, but sadly it hasn't been updated since 2007 as far as I can tell (Leopard Era) and thus may not be suitable for a newer Mac running Mountain Lion (the preference pane is also not 64-bit). iMacs and Macbook Pros all have different fan setups for different equipment and my Mac Mini has its own case fan. In my case, a Quad i7 will quickly reach 180+ degrees Fahrenheit or hotter when encoding with Handbrake at full speed. Apple's own fan FINALLY kicks in beyond a smidgen at around 90C/190F, but it doesn't reach near full speed until it gets hotter yet (it seems content to let the CPUs roast at 90C/190F; I think Intel's automatic throttle is at 105C/221F, so perhaps Apple thinks that 90 is perfectly fine. I'll admit the case isn't super hot or anything, but the concern should be the shelf life of the CPU and other components in the computer, not whether it will run at that temperture for weeks or months or even a year or two.
My PowerMac Digital Audio PPC tower (upgraded to 1.8GHz/1.5GB with dual 1.5TB Sata drives and used as a whole house audio/video server for over 6 years on nearly 24/7 and god knows how much before I bought it used in 2006) still works fine (case fan is starting to get a bit noisier, but still functions and the machine was on 24/7/365 for the most part! It was built in 2001! That's 11 years with no component failures and over 4 years 24/7 on the 1.5TB drives). I'd like my new Mac Mini Quad i7 to last at least half that long.
In short, there aren't many good solutions because no on has bothered (or at least bothered to update) a good fan control for the Mac. I found a fan control program to run in Windows on my Macbook Pro and it has no configurable options, but automatically ramps at a very good set of default temperatures and so it's just set to automatically run at startup and forget (I wish I could say the same about OSX; Apple's defaults seem to be set for quiet operation with little thought about longevity).
I'd gladly pay a few bucks to have a good quality fan control program in OSX that is up-to-date, 64-bit and works fine with my new computer in Mountain Lion. It's a shame I can't seem to find one to buy.

Mac Pro will not boot, revs fans at full speed

Hi,
I had my Mac Pro (2006 3.0 quad core) asleep, it woke itself up and didn't display video, instead revved the fans at full speed and did nothing, so I shut it down using the power button. When I turned it on, it did/does the same thing, no chime, no video to the displays, and I cant boot in safe mode or any other way, it wont even eject the DVD drive if I hold the mouse down.
has anyone encountered this before?
Any ideas?

Give the SMC button a kick, hold it in for 5-10 seconds. Hard to see, but hidden by drive #4.
Or try zapping PRAM/NVRAM first and see if that helps.

Macbook air cpu charge is lower than 5%, but temperature is more than 90°C and fans don't speed up ! is it normal ?

hello,
my macbook air cpu charge is lower than 5% (i.e. no apps are loaded only the finder, istat menu give me a cpu charge near 3%),
but temperature is more than 90°C and fans don't speed up !
is it normal ?

It is degrees C.
when the computer has a normal behavour with no CPU charge, its temp is about 35°C
but sometimes temp increase to 90°C and more.
because i don't heard the fan speed increasing (I almost don't heard the fan so i think they should stay at 2000rpm), I'm afraid to burn the CPU and shut down the mac
i didn't let him get hotter.

Satego X200 hangs about for one second if the fan changes the speed

Hello people,
my laptop hangs about for one second if the fan changes his speed. This does not happen so often and only since a short time.
Excuses me for my English.
Thank you in advance

First thank you for your responses.
Yes, notebook hangs for 1-3 seconds. I notice this because the mouse pointer does not move in this time. And if I hear music, only monotonous sound comes out. If the processor is busy, something like that does not happen. Only if he is idle. It is astonishing that notebook hangs if the fan goes on. I cannot ascertain, with the turning on which fan this passes.

Is this CPU fan or graphics card fan?
Yours sincerely

Laptop Fan not increasing speed

I was having very bad heating problems with my pc it would tend to go off all the tkme when it overheated, i decided to blow into the fan and dust came out. It continued to work perfectly untill last night when it continued to overheat, I checked on the Internet and I found I just had to clean the fan so I opened up my laptop this morning and cleaned the fan. But now the fan will not speed up if the temperature is high before it would and make horrible noises, now the fan is on but does not changes its speed when the cpu is heating!I have tried alot of freeware that increases the fan speed but the fan cannot be detected, but the fan is still on and idle. I opened up the laptop 3 times to check if everything was connected and they are but what could be the issue?? Please help my laptop is my life at the moment.

Please help my laptop is my life at the moment.This sounds like your fan need to be replaced. A fan on idle and not turning right? It should be constantly turning not idling...and only speed up when the Laptop tells it to speed up to dissipate the heat from the heat sink as heat rises. If it isn't doing this then the fan is failing.

Classic makes fans run full speed

I think this is new. When I run Classic my fans run full speed (10.4.8 G5 iMac 20") with any of the kid's games. I've done the SMU reset, blown dust from vents, tried different power settings. I think blowing out the dust reduced fan use in OS X, but not in classic.
Thermograph data suggests the fans are behaving appropriately, so I think the system is running hotter than in the past. Anyone have other ideas? Anyone else seeing this classic behavior?

Have a look at one post I made some months ago :
http://discussions.apple.com/message.jspa?messageID=1621311#1621311
I discovered that going back to Classic from one user to the other make a large use of CPU (80 to 90%) thus rising the temperature and conversly the fan...
If you open classic in one enironnment that's not true. Check it with Acivity Monitor.
Hope this helps.

CPU fan running full speed after 15 minutes

My 3 month old iMac 24" has just started having fan problems.
Before I went away on a training course, it was working fine. Left it switched off at the outlet for 3 days, now the CPU fan runs full speed after the iMac has been switched on for 15 to 20 minutes.
CPU temp is 24C, CPU heatsink is 28C. Ambient is 17C. CPU fan is 3600rpm. Other fans are normal.
CPU usage is less that 10%. Only Safari is running.
I've tried resetting the SMC - left all plugs disconnected for 15 minutes, reconnected mains power for 15 minutes, reconnected USB, then switched on.
Still the same - OK for 15 minutes, then CPU fan runs full speed.
Anything else that I can try?

I tried again, following your instructions exactly. It seemed to work, running normally for about an hour.
I left all the USB devices unplugged, except for the keyboard and mouse.
I then shut the iMac down, but left the mains power turned on at the wall. When I switched it on again 2 hours later, all was OK for 15 minutes, then the CPU fan ran at full speed.
Shutting down for a few seconds fixes it for another 15 minutes.
I'm wondering if it's a software problem, although I haven't loaded any apps recently, apart from a few monitoring programs since this problem appeared.
Last night I left it running the extended hardware test for a couple of hours, and the fans were fine.
One thing that I noticed yesterday was that the "GPU" temperature readings in iStat were all missing (just "-" displayed) for a couple of seconds when I clicked on Dashboard. Is there a way to keep iStat open while I'm using the iMac?
I think I'll try booting XP and see what happens.

Tecra A10-S3501 Power Light Flashes, Fan Runs Full Speed.

Greets all,
I have a customers Tecra in the shop, and after getting a good description of what was happening at the tme of failure, I still cannot seem to figure it out. She was watching a flash video when it froze. Upon reboot, it will not init the LCD, it does seem to at least partially POST, cd drive spins up, and all LCDs blink like normal. Still no LCD init, and the power light blinks green, no pattern, it is not a binary post led code. Fan spins up directly to full speed and stays there for the duration. I counted 20 one second blinks with fan at full speed, before powering down. Any ideas? Customer has no warranty, so would be nice to fix it for her. :-) Thank you, and have a great day.

Hey,
Can you see a picture on external monitor? If yes it might be only a FL inverter issue of internal display. This is not an expensive part so this would be easy to fix the problem.
Anyway, if you cant see a picture on external monitor, I think its related to another part, maybe mainboard or something else. This should be checked from an authorized service provider
By the way: If you have connected an external monitor, use FN+F5 key combination to switch between them

Fan runs full speed at start up

HP Pavilion p6-2037cb purchased 1/19/12. Windows 7. There is no error message.
When I turn the computer on after it has been off all night the fan runs full speed. This happened a few times in the first month. The first time it stopped itself after a few minutes. Then I learned to stop it by simply restarting the computer. This still works, but what used to happen a couple times a month, has happened twice in two days so I worry the problem is getting worse.
It never happens when I am using the computer because I do nothing that requires a lot of cpu's or causes heating. I just surf the web and do email. No games or videos or TV.
If it is a fan connection problem I would like to know the nearest repair service. I would rather bring it in than ship it. But I can't find a list of authorized warranty repair service centers. I followed links on HP Support Assistant but got sent to a site that does not list Pavilions.
I need to know why the fan runs full speed at start up and where to get it fixed near where I live.

MacBook 2007: 104°C and fan beyond maximum speed!

Hello.
2 years ago I bought this MacBook Late 2007 2GHz Intel Core 2 Duo model. It wasn't new though it worked like it should. I use my MacBook nearly every day for at least 6 hours a day. It has OS X 10.6.8 and Windows 7 running nicely on my SSD, so there's no complaining about it's speed as it still just feels new.
It has one big problem though. As I use my MacBook for watching videos, listening to music and gaming etc., my MacBook always runs very hot (~80-100°C). This became a standard for the last few months. When I turn on my MacBook it's processor about 15°C hotter than room temperature. Though it only warms up when actually doing something, this normally lasts for a minute because I'll start using it immediately. Right now I'm typing this question, my MacBook is 58°C. Safari has 2 tabs open, and iTunes is running in the background. The fan is running at 4500rp/m. This is the lowest temperature I can achieve while using the MacBook. When I first bought this MacBook it would run at 30°C while using it. Now it's around 60°C.
When it's beyond 60°C the fans will start running to their maximum speed, which is 6200rp/m. However this month I started to notice something that I consider dangerous. My Core 2 Duo reaches 104°C while watching a 480p video! That's 1 degree away from turning off. I know that MacBooks are designed to run at these temperatures, but actually acieving this temperature on watching a video or playing a two-dimensional game is just rediculous.
I'm pretty sure it has something to do with the thermal paste, and though I'm specialized in these kind of things, I don't want to screw up the MacBook. It runs super fast because of the SSD. Buying me a new MacBook would be a total loss of money since it still performs very well.
I've tried tools like SMCFanControl. Of course it doesn't help because any CPU will warm up when doing intensive tasks. I don't find it helpful.
Lastly, the fan's maximum speed is officially 6200rp/m. Mine reaches 7600rp/m (this is the fan that came with my MacBook. Not a custom one.) and after a short period of time it shuts off. After a second or two it'll turn on again. When this happens it's at 104°C.
Any advice?
Thanks in advance!.

I have essentially the same computer and I'm wondering if perhaps your fan is failing? That could explain some of the odd behaviors and readings you're seeing!
My computer typically runs at 70C when I'm using it (I'll have Chrome open with several tabs, at least one of which has a lot of Flash content) and the fan runs around 6200 rpm.
Streaming videos always brings up the temperature to levels similar to what you're seeing - and I believe it's always done that. I can't recall a time when it didn't.
Could you give the link for some of the videos you watch that are causing the fan speed and temperature to increase? I'll try them on my machine and see if it exhibits the same behavior.
Also, keep in mind that many sites that stream videos or have games on them use Adobe's Flash plugin, which is terrible on OS X. It will ramp up the CPU usage to an incredible degree, which in turn means the temperature and fan speed will go up.

IMac fans running full speed constantly.

A few days ago my iMac's fans started running at full speed, which they very rarely do. Now every time I turn on my computer after about a minute the fans reach full speed, I'm only opening Google Chrome, Twitter, iTunes and Coversutra which has never caused the fans to run before.
I've downloaded a program to monitor temperatures of various parts of the iMac but nothing is getting hot enough to cause the fans to run at full speed.
I have reset the SMC and PRAM multiple times which hasn't fixed the issue. I've run the Apple Hardware Test on the original install disks which gave an issue number relating to the fact that the fans are running on full speed.. surprise surprise...
The computer isn't very old, was purchased almost to this date in 2009. It's an 8,1 iMac with a 20" screen. 4GB RAM and a 2.4Ghz processor.
Would be extremely appreciative if anyone has any idea how to fix this problem.

Get free iStat Pro. This code is obviously related to the HD, but I don't know if it necessarily means the HD is failing. It will show the fan rpms to see which fan is revving up. If it's only the HD fan that is climbing up, this may be related to the HD temperature sensor being faulty. Thing is, the sensor is probably integrated into the drive, so if it's only that that's failing, it will still involve replacing the drive.

Also, run the demo of SMART utility to check out your drive.

What does it say for SMART Status for the drive in Disk Utility?

Fans run full speed when using Parallels

I have Parallels installed on my MacBook but the problems is, whenever I run Windows XP, the fans run at full speed. I try not to run too many programs but nothing seems to help.
Any suggestions?

I think that it's normal that the fans run full speed when you use Parallels. It also means that your MacBook's thermal paste was applied well.
Runing Windows XP in Parallels is a CPU intensive task and it takes a lot of power to run it. As a consequence the CPU get hot and the heat is transfered to the cooler, where the temp sensors sense it and make the fans run faster.
It's normal.
I bet your MB doesn't get as hot as some do...
