MacFreePops causes fans to run

While at school I've really gotten used to using Entourage to check my Hotmail accounts. Now that I have my own computer though, I don't plan on having Microsoft Office (I have Office for Windows already, and iWork). I've been using Thunderbird lately, but just noticed MacFreePops is running at a CPU % of over 190, causing my fans to run almost constantly. After I quit MacFreePops my fans stopped.
I really would like to continue using Thunderbird for email, but is there another client like MacFreePops that won't cause my fans to run?

Working fine for now

Safari Update 8.14.14 causing fan to run loud?

I just did the update for Safari 7.0.6 on 8.14.14 and now it appears that my computer fan is running a lot louder after I did this update. I know that it is not the fan not working correctly or the vent is clogged because I am using Chrome right now to type this message and the fan is running normally. I am wondering if others are having problems with this new update and/or how to solve the problem of the latest Safari update causing the fan to run louder.
Any advice would be appreciated.

Extensions and plug-ins can increase fan speeds not just the browser itself.
From the Safari menu bar click Safari > Preferences then select the Extensions tab. Turn that OFF, quit and relaunch Safari to test.
Check the fan noise. If it decreases, turn extensions back one at a time to test until you find the culprit.
If it's not an extensions issue, try troubleshooting third party plug-ins.
Back to Safari > Preferences. This time select the Security tab. Deselect: Allow all other plug-ins. Quit and relaunch Safari to test.
If that made a difference, instructions for troubleshooting plugins here.

Radeon HD 4870 and HD 2600 XT causes fans to run faster

I just installed a Radeon HD 4870 in my early o8 Mac Pro in PCIE Slot 1. I also moved my original 2600 XT in PCI slot 3 (have also tried it in slot 2 with the same results). I have 2 monitors connected to the 2600 and 1 32" HD TV connected to the 4870. For some reason now my exhaust fan and HD expansion fan is running faster than before I added the 4870. Exhaust is 1148rpm and HD expansion is 2099. Is this just because of the extra heat generated by the 4870 or is something not right here? Thanks.

Just tried running with only the 4870 and do not get the high fan speeds. It only occurs when both cards are installed.

Portege R700 -- disabling Intel AMT in BIOS causes fan to run constantly

I recently purchased a Portege R700-1321, which shipped with BIOS 1.40. I'm running Windows 7 Pro x64. I have attempted to disable Intel Active Management Technology (AMT) on this machine by going into the ME BIOS (via ctrl-P at bootup), setting an admin password, and then disabling ME completely. However, when I reboot after disabling ME, the fan starts to run at high speed and runs continually so long as the machine is powered on. Re-enabling ME in the BIOS and rebooting again causes the fan to behave normally.
I believe this is a BIOS rather than Windows problem because upon booting the machine, the fan steps up from low to high speed over the course of about a second before the Windows startup screen appears. Windows appears to be fine despite the continually running fan, so AFAIK this is not the freezing-up issue that has been reported for R700s, despite the similar involvement of the fan.
Is anyone else seeing a similar issue?

I noticed that when battery is charging the miniPCI temperature spikes to 50 degrees. Unplugging the AC or reaching the charging threshold causes sudden drop in the temperature. The interesting thing is that the minipci sensor is near the southbridge (near the ram) and the battery sensor itself stays stable at 30 degrees.

SyncServer constantly using high CPU, causing fans to run

Has anybody found a solution for when the SyncServer process runs wild? I'm running OS X 10.7.1. In the last day or so I've had a problem where I find my laptop's fans are constantly running. Opening Activity Monitor shows the SyncServer process eating a consistent 20-30% of my CPU. I've left it going all day and it never stops.
From what I've been able to determine so far, the SyncServer process doesn't cause any problems until I launch iTunes and sync my iPhone. After that it keeps running. I upgraded to iTunes 10.4.1 yesterday, but I _think_ this problem started just beforehand when I was still running 10.4.
If anyone has any insight I'd appreciate it.

I resolved a similar situation. I am running OS 10.6.8 and noticed my fan was on constantly. ActivityMonitor showed the syncserver process using about 15-30% of CPU cycles, with iCal showing up suspiciously high on the CPU list. I downloaded syncrospector v4.0 from http://goo.gl/logoG (I got that lead from http://help.jools.me/kb/21) and running that app I could see that iCal was syncing about once per second! A bit more searching took me to http://support.apple.com/kb/TS1627, and there I found the answer.
"If you see the Sync menu in the menu bar, skip to step 4: "
I hadn't noticed the little icon in the menu bar, but there it was with an exclamation mark inside it. Clicking on that I saw a message that there were "conflicts" (about 10, it turned out). I resolved those and the syncserver problem went away.
Now, there is probably an underlying problem, still. Just because there are conflicts between iCal and my iPhone, iCal should not be trying to sync more than once per second. For now, though, I am content. I'm not going to try to figure out what was really going on.
By the way, this all started when my daughter plugged her iPhone (an old one of mine) into my laptop. Evidently the old calendar entries on that phone for some reason conflicted with old entries on iCal.

Upgrading to 10.9.4 causes slower startup time & system gets hot and causes fan to run during startup for no reason! Never did this before.

Macbook pro 7,1, osx 10.9.4.. just upgraded from 10.9.3. 10.9.2 was installed fresh in January.
Before that I had snow leopard. Never before has the fan turned on during startup in the 3.5 years I've owned this machine. That means the laptop gets hot? Why would it get hot at startup? And it takes 5-10 seconds longer to boot now too.

Same problem here. I just upgraded from 10.9.3 to 10.9.4 and the fan hasn't stopped since. Before seeing this post I was starting to get VERY worried. Now I'm thinkin..... Apple - ya gotta fix something here!!

Mdnsresponder will not quit. Consumes above 100% CPU and kills my battery. Also causes my fan to run constantly and my computer to get extremely hot. Force quitting doesn't work. It just comes back.

mDNSResponder is a background process that runs all the time. If you kill it, it's relaunched automatically.
Please launch the Console application and select "system.log" from the file list. Enter "mDNSResponder" (without the quotes) in the search field. Post a sample of the log messages in the Console window -- only one example of each repeated message, please.

Youtube causing my computer's fans to run?

So I've posted on here before about my fans acting up. I've noticed something recently. Anytime I'm on youtube.com, my fans will run if I have the computer plugged into the wall. However, If I have it unplugged my fans won't run at all. Is this normal and happen to anyone else?

This does not sound normal to me. Someone on this forum had a similar problem, and it turned out that he has a process running in the background that was causing an extreme amount of CPU usage and causing the heat and fans to run to excess.
Open Activity Monitor and set it to show all processes. Then look for something using a ridiculous amount of the CPU and quit that process and see if it helps.
Another thing to do--run the Apple Hardware Test to see if you have a defective thermal sensor or something like that.
But I don't think what you are experiencing is normal, and I think in time the heat will compromise your logic board. Be sure and get 3 year Applecare if you haven't already.
Good luck!

Can an error in battery cause a slow CPUS and the fan to run non-stop?

tthe battery need serviced but my computer runs slow and the fan is running non-stop. MacBook Pro 13" purchased around 2011.

OK, you really need to dump that Windows attitude quickly, because what worked over there is completely useless here. I never understood the "upgrade didn't work obviously, because this or that happened, so how do I downgrade." I hang out around here, and I haven't seen many comments about fans running full blast after the updates. I did them, and nothing happened.
First, you can't downgrade the firmware EFI update. I think if you tried, it would brick your MBP.
You could reinstall Lion if you wanted, but that's really a pain, and once again, one of those Windows things that people always do that wastes time. A security update and Remote Desktop Client (which only runs if you start it up) would not effect your fan speed.
Apple does have "restore points", but it's a real backup system that requires a backup drive. It's called Time Machine and it's preinstalled on your Mac, easy to use, and allows you to go as far back in time on your Mac as the size of your backup drive will allow.
Now, after all that, let's try to figure out what's going on with your fans. First, did you do the EFI update correctly? Meaning did you do it when the MBP was actually plugged into the wall? What are you running? Games? Videos? Something else?

Fan randomly running loud + computer not responding

I have been facing a problem for the last several weeks on my PowerMac G5 that technicians have not been able to solve either.
The computer randomly stops responding and the fans start accelerating slowly until they reach their top speed and then stay at that speed for indefinite periods of time. I cannot see any pattern in this - it happens both when the computer is running some process and when it is idle.
Each time this happens, the only option for me is to do a hard powerdown (hold down the power button).
I saw another question about fans running at high speed, but that case, it seemed as if the computer continued to respond.
Any help on this would be appreciated.

I am having the same problem.
Now before you start taking advice to back up all your data, reformat your hard drive, and reinstall all the software; please take note of a few things:
first off, I'm disappointed/frustrated/melancholy that this is happening to me. I spend $5000+ for a "reliable" Apple computer. Then it doesn't want to turn on because its not safe. Sorry if I drown this post with bitter sarcasm but I am coming to the end of the line with my patience.
I called Apple Care, read a bunch of posts (here and elsewhere), and yes I do know about the SMU Reset button (like that really does anything?).
My problem happened a few weeks ago and I thought nothing of it at first. There was a power outage for a quick second and it turned everything off. When I went to turn on my computer, there was no chime, the red light was on, and the fans were running and eventually began running very loud. After letting it run like that in hopes of the screen lighting up, I turned it off by holding the power button. By the way, there's nothing on the screen and the keyboard doesn't work (I use a wireless keyboard, but I plugged in the OG cord keyboard to push whatever series of buttons recommended by these "geniuses") Trust me, the computer doesn't make it to that part of the boot process, so stop with commandoption+PR or F12 to get the CD out. It doesn't work! What's up with this computer! It can handle all these intense calculations,etc. but a power surge is going to shut it down indefinitely.
So I left the computer came back the next day, turned it on and its fine. Cool, I'm happy. It's Working!! I go on a few weeks, then I go to turn it on this Monday, same problem. But actually a worse situation. I had a client come over and the computer wouldn't work. I looked like a idiot. Couldn't do anything cause my computer didn't want to turn on. I do music production/editing. I use my G5 for running ProTools LE. I have other programs but that is the main one I use. There's nothing wrong with it. It's optimized for use with the mac. So those people who are going to advise me to uninstall all my software and all that - I appreciate your concern but don't give advice when you don't know anything!
So I am getting frustrated. My client left a little disappointed, but what can you do? I tried to call AppleCare on Mon. but it was Memorial Day. So I waited for Tues.
Tues morning, my computer turns on like everything is fine.
I'm happy but cautious. I talk to AppleCare rep. He tells me that it is a common problem they have heard about with the G5's. Wherever blackouts, brownouts, spikes, sags, dips, and other electricity inconsistencies occur, the Power Mac G5 has a breaker in it which flips so it doesn't receive uneven power supply and damage internal components.
I like that feature. Good thinking Apple. Protecting my investment from bad electrical grids. But I don't like the fact my computer has a mind of its own where it decides when it wants to boot or when it wants to sit there and run its fans all loud.
I shut down Tues morn to go to work. I come back in the evening, it doesn't want to boot up. Instead of getting angry trying a bunch of times to turn on/turn off the computer, I leave my house all together and go and have a few drinks. I come home ,don't even look at my computer, and go to bed.
I wake up Wed. morning. Go to turn on my computer. Successful boot. It's running. Okay, I think, I'm going to get down to the problem. I read all the logs, not like I know every piece of info, but just to see what's happening. Everything looks fine. I decide to run the AppleCare CD Tech Tool. It says restart holding down C. I do that. When the gray Apple Logo comes up, all this writing about kernals comes up and it tells me to restart or shutdown. I shutdown and attempt to restart, same problem: no chime, red light on, and fans eventually spin loud. Now the CD is stuck in there. I'm going to take it to the Apple Store tomorrow to if these "geniuses" can figure it out.
(Just a side note: Apple calls them geniuses, but its hard for me to think some disconnected college kid with a bad haircut and questionable social skills knows what's up with the power supply issues of a computer; maybe I'm wrong, but you can run your diagnostics and look at the chart of what to do and all that BUT Apple needs to listen to the people)
I am going to get a UPS (uninteruptable power supply) with a clean sine wave output to curb the issue at my end. It's not my fault I live in a area that receives uneven power output. I live in Los Angeles. Summer is starting up and I think its going to be hot, so blackouts, power dips and sags are inevitable. I just don't understand why Apple hasn't considered this problem and fixed it with something:
A recall to change the power supply, Is it something on the logic board?, are they going to reimburse me for lost income (Ha, yeah right)
I really want to know how many people are having this problem?
From what I've heard, it is a common problem.
So I think we need a common solution.
If its so common, it must be the computer. We are all going to live in different areas where the power may vary. Not all of us have the consistent power flow of 1 Infinite Loop in Cupertino, CA. So if it is such a common problem, Apple needs to fix it.
I can't spend more than five grand on a super duper computer and have it wuss out on some power issues.
Its a loss of income and productivity to me.
I can't have that anymore.
Sometimes my computer turns on, sometimes it doesn't.
I bought my PowerMac G5 in April 2006, its been about a month and a half and I'm having these problems.
Thank you for your time.
If anyone else has been having this problem, I feel for you.
It was been very difficult for me not to curse in this post, but I have tried to extend the same respect to all that use these discussion boards to create dialogue, find help, and create solutions.
LETS FIX IT!
Peace,

Macbook Pro Fan Continues Running After download Error -- Please Help so Loud

Hello,
I recently tried to download the Citrix reciever application onto my Macbook pro. The installation was taking an excessive period of time and it was obvious that something had gone wrong in the download because it had taken several hours and was stuck at a certain step. I tried to cancel the installation but it wouldn't allow me. So I force quit the installation and thought that it was shut down, but I was mistaken. The next time I opened my computer the fan was running at an increased rate and was very loud and the computer was heating up. I tried to restart the computer and it said that the program was still trying to download and that the computer could not be shut down until completed. I got frustrated and basically forced a power down by signing out and holding the power button or something of that nature till it shut down. I waited overnight and then powered it back up but nothing had changed and the fan was still running like crazy but it says the program is not trying to install anymore though. I checked the activity level and CPU but nothing is out of ordinary of high. The program is not anywhere on my computer either so I have no idea what is going on and cannot figure out how to stop this fan running like this. It is draining my battery, overheating my computer and is annoying too.
Any help, hints or ideas would be greatly appreciated or I will be forced to visit the apple store for some help I guess.
Thanks,

Unfortunately, spoke way to early. The fan issue is still a big problem. From the second the machine is turned on, the fan cranks up. Frankly, I think this is overheating the machine to some extent (running the fan at max speeds when it's not even warm). Additionally, the noise caused by this has only gotten worse, and now it is even making a "whistling sound." Looks like I'm going to be making the trek to the Genious Bar, but based on comments by others on this issue I am not optimistic about a fix.

Closed lid, fans always running

Howdy. I've been using my MBP in closed lid mode attached to a Cinema Display. I expected the fans to run constantly when in use, especially with XP running in Parallels. When I put the computer to sleep--still attached to monitor, usb keyboard, bluetooth mouse and power adapter--it acts as I suspect it would, fans stop, front LED starts fading in and out. However, I'll come back later and the LED will be solid, display blank, and the fans running away. The keyboard or mouse will wake the computer and then it runs as normal. This has happened overnight as well as in half an hour, and several times.
I am kind of getting concerned about using the computer this way. Fans always fail, and I am not really looking forward to opening the computer up again.
I guess my questions are: why would the computer be running the fans, especially after being in sleep for hours, and is it shortening my MBPs expected life using it with the lid closed?
Thanks.

I'd guess/assume that something is actually waking it from sleep and causing the heat/fan activity and that when you return you're not actually waking it up just re-activating it from screensaver mode ...
Run Utilities/Console and click 'All Messages' top left - what lines appear during the time you think it should be sleeping ?
It isn't shortening the life of the hardware using it in clamshell mode but if something is causing it to overheat regularly that will have an impact on internal components/motherboard that could be detrimental.

I have a dual 1.8 ghz pwer pc g5 and sometimes i put it in sleep mode and come home on my lunch break and the fan is running at full speed and the computer has frozen up...what is going on here?

and sometimes i put it in sleep mode and come home on my lunch break and the fan is running at full speed and the computer has frozen up...what is going on here? is it a virus or has my computer been hijacked? it cant be good for the computer...anyone ever had this problem..?

Your problem has been reported many times, but causes are as varied as individuals.
Can we assume that a hard shutdown allows a normal restart?
Can I assume that you have used Disk Utility from your OS X install disc to repair the hard drive directory? The freezes and hard shutdowns require that the drive be repaired (not permissions) or soon the machine won't boot at all.
If the root issue is software related, in Console (the application) under Logs, there should be loggings around the time of sleep and logs that tell you what process went wild and froze the machine.
Network activity is also a common casue.
Other info:
http://support.apple.com/kb/ht1776
If hardware related, such as an external drive, other USB device (Wacom tablet) or USB PCI card, ejecting, disconnecting, removing, or in the case of the Wacom, updating drivers, are all potential remedies.

Fan constantly runs when the computer is in use, as soon as I turn it on, the fan starts up, help?

Does anyone know what might cause the fan on my mac to run constantly? As soon as I turn it on and the unit is clearly not warm yet, the fan is going.

If your iMac has an Intel processor, reset the SMC:
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.
Apple says that should fix a fan that runs regardless of systems load. If that doesn't fix it, please post back.

Fans are running on high at all times

for some reason the fans on my computer are running oh high at all times. from the second i turn my computer on, even if the computer has been turned off for days.
does anyone know why this is?

Hi chasensanborg-
Try it with the drives disconnected. If the problem goes away, try plugging the drives in one at a time until you find the culprit.
LaCie drives tend to have power supply bricks that fail intermittently and get progressively worse. The symptom is difficult to troubleshoot as the drive will attempt to pull whatever power it needs from the FireWire bus if the brick is not supplying the right amount of juice. This can put a load on the power supply of the Mac and cause the fan to run more quickly in order to compensate for the heat generated by the load.
Luck-
-DP
