Iavd is 98%, computer gets real hot, fans running fast
Hello,
I see from some posts of last year, unresolved, I guess, that iavd (anti-virus?) is
very high for no good reason, meaning it's taking lots of processor (space? function?) and the computer gets hot and the fans run fast.
Mine has been doing that for a long time.
Does Apple know what causes this?
A fix might help lower my electric bill.
Thank you.
Not to mention computer wear and tear. I think it is the nature of the beast though, as all antivirus programs can have a tendency to cause a shorter life expectancy on a hard drive and other parts of the system. I skip the AV altogether on mine, and simply choose to browse carefully and stay away from filesharing apps and the like.

why is my macbook air getting so hot, fan running, and burning through the battery fast?
I have started to experience my computer getting really hot also. Since one month back in time it has started to get raging hot (up to 99 degrees celsius) just by surfing the internet. Sometimes it stays that hot but most of the time the temperature gets lower after about 15 minutes..
this has never happend before and i am starting to get worried..
what is the problem and is there a sollution?? -

I've had my Macbook pro for about 3 1/2 years now. It has worked great until recently. A few months ago I noticed that the fan would always run really fast when I was doing simple tasks. After a few weeks/months, the fan was still really fast but it also started to make these loud noises. Now, it only occasionally makes the loud noise if I move my computer after its been stationary for a while. The fan no longer works at all and my computer gets exceptionally hot almost instantly when I turn it on. Is there a way to fix this problem without having to pay a ton of money to have someone fix it for me?
You can try a SMC reset:

The bottom of the computer gets very hot
I just got this macbook pro MC721ll/a. The bottom of the computer gets very hot as it is sitting on my lap. I have never had a mac before but I don't think it should be doing that. Also, I don't hear any fans running. Is this normal?
The OS keeps the fans at a minimal speed because running them any faster would needlessly use extra energy and make more noise. Manually setting your fan speed won't wear out the fans because they're brushless AC fans (so they're not subject to any significant mechanical wear as they spin). One thing to keep in mind about SMC FanControl: Apple engineers spent a great deal of time, and probably money as well, designing the cooling systems for the computer (both in terms of the physical systems, and the algorithms that control the fans and regulate the voltages of the components). In addition, Intel CPUs have their own separate temperature monitoring systems which will severely throttle or even shut down the CPU if temperatures get dangerously high. So even in the extremely unlikely event that your fans ever actually spin too slowly, the computer will still shut itself off before anything bad happens.
And to answer your first question, it is definitely normal for the bottom of the Macbook to get hot because the body is made from aluminum, one of the best thermal conductors known. Basically the bottom acts as a heat sink, allowing the Macbook to cool off more efficiently and run faster. Most other manufacturers make the bodies of their laptops from plastics, which conduct heat about as well as fiberglass insulation or a mink coat. -
My mac gets real hot! Is this normal
I am new to mac. My mac getting real hot when i hv it on more than an hour, is this normal? Do i need to install a fan or something?
Welcome to Apple Discussions!
Do you have a 24" iMac with an ATI 4850? A recent firmware update became available for it, which may solve problems with that GPU:
http://support.apple.com/downloads/iMac_EFI_Firmware_Update_14
If that's not the Mac do you have, please more clearly identify your Mac*:
http://www.macmaps.com/macosxnative.html#IDENTIFY
So we can suggest the correct hardware test instructions, and then determine what is the cause. Also I suggest backing up your data*:

i wonder why macbook pro gets real hot, i am just running the safari!!, is it normal? how can i check whether this heat is normanl?
That's not where it should be
Perhaps technically, but I rarely use my MBP anywhere else, and even when playing something like Portal 2 or Bioshock 2, it never gets more than uncomfortably warm near the hinge. I just make sure that part's not resting on my knees.
I know someone's going to come along and give me all kinds of good reasons why I shouldn't be doing that, as it seems to happen every time I admit to this. But when my practical experience over ten years of using Mac laptops tells me it's not a problem, then I tend not to listen. -
My macbook pro gets very hot when running anything like games or videos
I just bought a macbook pro 2.3 GHZ i7 with retina display. It gets very hot when running just about anything of substance. When I run a game like candy crush, the temperature can get to 167 or more. I installed istat menus and started monitoring it. I did notice that the fans never went on but after istats I was able to make them come on. Without having a game going, the temperatures hover around 100. Once the game starts, it goes crazy.
I don't really know what the problem could be or if this is normal (it really can't be....This is way too hot). I have owned the computer for about 2 months and I need to know what to do.You are still under warranty. Call Apple Care. Make sure you get a case number as all repairs have an additional 90 days of warranty.

G4 Wont Start Up No chime and fan runs fast.
Hi Mac Users,
I am at my wits end! My Mac won't start up.When I switch it on there is no chime and the fan runs fast.
I have checked the battery and it is OK.
Tried the reset button and no joy.
I have reseated the ram memory still no improvement.
I am completely lost without my computer would some kind soul point me in the right direection?
It is the hub of my recording studio and my life cos I'm disabled.
I have read a lots of posts on here and I feel I am getting confused with too much information.
My names not Dan but I am desperate?...........Dylan.The red LED indicates power to the logic board, which is good.
Try Resetting the Logic Board
Resetting the logic board can resolve many system problems. Whenever you have a
unit that fails to power up, you should follow this procedure
before replacing any modules.
1 Unplug the computer.
2 Press the Power On button on the front of the unit.
3 Open the side access panel.
4 Remove the battery from the logic board.
5 Wait at least 10 minutes before replacing the battery.
6 Make sure the battery is installed in the correct +/-
direction.
7 Reassemble the computer and test the unit.
Note:
This procedure resets the computer’s PRAM. Be sure to
check the computer’s time/date and other system parameter settings

OK. When I install the 10.5.8 combo updater and restart the Mac it closes down as far as the screen goes blank, but then the fans start running slow at first but after about 2 minuets they are running as fast as possible, should I leave them running? I have left them in the past for up to 2 hours but then I decided to push the button to force quit, just how long should I leave them running? And is this normal?
ThanksThat is a retail upgrade to a new system; not a gratis update within one.
The ownership & use of a retail 10.5 Leopard DVD installer disc set is required.
A disc from another computer won't work in a different one, so that's out, too.
+In your post's signature line, you say the G5 shown is running 10.5.8; if so+
+do you have another computer now, with 10.4.11 installed? Or was the issue+
+you had mentioned, due to attempting to run the Leopard 10.5.8 update step+
+in a Tiger 10.4.11 system? Usually, those kinds of things never get very far.+
(If you know someone who has upgraded to Snow Leopard 10.6, & has
no further need for their old 10.5 installer disc set, they may make a deal.)
Sadly, the normal retail sources for buying a new/unused Leopard 10.5 disc
set won't have them; so other options and sources have to be examined or
researched. One possible source may be to call the main Apple phone number
for the sales support (see web page) at 1-800-MY-APPLE and ask for a Mac
OS X 10.5 specialist; and inquire about the purchase of the Leopard 10.5 full
install disc set, which is essentially the retail disc for a complete installation.
+In regions outside of North America, you may have to contact your nearest+
+Apple main sale support & inquire about getting the Leopard OS X 10.5 discs.+
The best way to upgrade to Leopard 10.5.8 is to have a separate hard disk drive
(if you have a tower computer) for it, all alone; no old Tiger or other OS X parts.
And if you use iLife, get a later version of that suitable for the hardware in your
computer; as not all older Macs can support the latest iLife. Some may prefer to
be using iLife 06 or 08, if they don't have all the newer stuff. Older ones may be
better with an even older version. Since iTunes is a separate download item, that
may also be too much for some ancient computers. Of course, newer iPads and
other items probably need to get into the iTunes store and interface with the Mac.
Those would require the minimums as indicated by their system requirements list.
If you are on the lookout ahead of time, getting a clean no longer in use Leopard
DVD retail installer disc may be a matter of timing and luck, in your vicinity. A few
weeks ago, a craigslist ad had some Apple OS X software including the 10.5 DVD,
in the box with book; an iLife 08 in box with instructions, Garageband jam-pack, a
white Apple usb keyboard, and iWorks 05 in the box with paperwork; all for $50.
And someone else, a few years ago, gave me an early retail Leopard 10.5 DVD.
So, I could easily upgrade one of my Macs (again) to Leopard 10.5.8 and have no
old Tiger system parts inside the computer at all. - A clean break, as I'd done before.
Be sure your computer has better than minimum hardware requirements to run
Leopard 10.5.8, including more than enough RAM, large capacity hard disk drive
with large cache and good read/write speed; and a good Superdrive optical drive.
If the issue with the 'fans running fast' has been resolved, or is conditional, you
could add whatever new info you have in this thread. And if you are considering
an upgrade to Leopard 10.5.8, issues outside of the actual computer hardware
seem to appear in the Leopard discussion page, if you needed to start a thread.
Sometimes, getting the dust and other debris out of a computer so it can breathe
and get adequate air-flow, can help it run cooler. But sometimes, there are other
possible reasons why, if it is running too warm, for it to be doing that. Do you have
and use a Temperature Monitor software that an be read in the main menu bar?
A temp widget is mostly pointless, since in order for that to work, you have to stop
most everything else & run DashBoard. That can further load the system, to make
it run warmer; if the issue of heat and fans remains an issue to be watchful over.
Hopefully a few of your questions or curiosities are finding answers; at times, a
fair gamble on information can be a google search. If worded adequately.
Good luck & happy computing! -
This quesiton has been brought up many times before, and I've tried the suggestions everyone has offered in resloving the problem of fans running fast on a Mac Pro. In my case they started running fast after Sleep, Restart or after Startup. I have a 2007 Mac Pro and have reset the PRAM and SMC in the past and these, along with updates from Apple, seem to have resovled the problem. Recently, however, I began to have this trouble again and went throught the motions of resetting PRAM and SMC. I even reinstalled my OS Lion to see if that would resolve the issue, but to no avail. So this is why I am writing. In an effort to give someone else a heads up to a new problem I incurred that hasn't been brought up in any discussions on the subject to this point; that I can find, anyway.
About 8 months ago I had one stick of Ram blow on me. I sent it back to OWC and it was replaced no problem. Then I noticed a month ago that all the RAM on my lower riser, except the replacement stick, had blown. Again, all were replaced and this is when the fan issue arose. I tested the RAM on the Upper Riser in the lower slot and they worked. I put the Ram from the Upper Riser on the Lower Riser Board to make sure it worked, and they did. I did this, however, after thinking I had blown the Lower Riser Board and ordered a replacement...glad I did. I now had 8 sticks of Ram in the Upper and Lower Riser all working well, but had a computer that sounded like a 744 just before take off. After numerous attemptst to fix the problem and searching long on the internet I decided to try the New Riser Board I had bought. It workded. That Lower Riser Board, for what ever reason, must be foul somewhere/somehow. I now longer have the problem.
So, I suggest you follow all the advice of those who have written before me because their suggestions worked initially. However, if you've had blown RAM recently, or maybe are about to and this is an indicator you have a Riser Board problem, you just may want to check your Riser's one at a time in both slots to see if the fans run fast while Board is in and the other is not.I would - in today's world with SQL-injection hitting everything from "mom and pop" to govt and university sites and everyone in-between, to look at how well Vista handles malware.

Satellite C55-A - after BIOS update cooling fan runs faster
Hello,
I was informed by Toshiba application that new BIOS version is available I confirmed it and BIOS was updated. Now I have problem. Cooling fan runs faster than before and it is very annoying.
Can I find older BIOS version somewhere and roll it back? I don't need it if it doesn't work properly.
Now I have version 1.40. Is there some solution for this new version?
Message was edited: posting has been translatedToshiba EU driver page provides only the latest BIOS version.
Furthermore the BIOS downgrade isnt possible using the win-bases BIOS update.
In order to downgrade the BIOS on Toshiba unit, you will need to use the traditional BIOS update method which requires special BIOS version. This is available only for authorized service provider.
At the other hand there must be an serious reason why the cooling module run faster.
Maybe the cooling method has been improved in new BIOS just to ensure that internal parts would be cooled down properly.
Its just an assumption but I think it makes sense
By the way: after each BIOS update, you should load the BIOS default settings and should save the changes. If you havent done this in the past, do it
