Problem with notebook fan!?

Hello, i have bought HP 2000-2b43dx before 15 days and I am sneaking suspicion there is problem wih fan/vent on my notebook.
When I turned my notebook first time, and next 2-3 days, my fan was so silence that i couldnt hear his work so its normal because when I turn notebook there is no hard operations that fan needs to cooling components.
After using my notebook for 3-4 days I noticed that my fan start cooling immediately when i turn notebook and fan is no longer silent like first 2-3 days. So, my fan is always cooling, i can feel and hear it, no matter what i am doing on my notebook. When I closed all my apps, the fan is still cooling for long time. is it normal if I use notebook only for internet and we know that internet doesnt cause components to be heat.
i have one pic from user manaul, where we can see that fan needs to cycle on and off during routine operation, but my fan is almost always ON. Here is pic
This question was solved.

Having the fan come on is generally automatic. It depends on the notebook as far as which utility controls the cooling fan. My current product loaner HP Envy17-3002ea notebook has HP CoolSense, but not all notebooks have it. Some notebook's cooling is controlled by an algorithm in the BIOS ROM that is based on the temperature ramp (delta) in the system board and CPU.
The fan come on when your notebook starts up is quite normal. If the temperature gets too hot the the CPU will shut itself down as a self protective measure. There are a number of utility programs one can use if one is a bit paraniod about a notebook's CPU temperature, but generally speaking, there isn't really much to worry about.

Problems with G5 fans coming on...

I have a very early Power Mac Dual 2GHz PowerPC G5 running OSX 10.4.11 which has started having strange problems... For apparantly no reason all the fans come on and stay on - this can sometimes be resolved with a restart, sometimes not, in which case I need to shut the machine down - after which it will sometimes not reboot the first time (gets as far a blue screen then hangs) - I then need to unplug it from the mains for 10 mins or so, afer which it will start up normally.
Looking into the problem I have discovered this message in the system log every time it happens:
Jan 10 22:01:19 teknomage kernel[0]: AppleMaxim6690::readI2C error (0xE00002C2) I2CAddr = 0x98, subAddr = 0x01
Jan 10 22:01:19 teknomage kernel[0]: AppleMaxim6690::getExternalTemp read temp failed!
I have also started running a temperature & hardware monitor to try and get to the bottom of this and have discovered that all my temperatures show a flatline when the fault is about to occur. If I then restart the machine, all fans will be running. If the machine starts up with all fans running. On one occasion, CPU A showed a flatline temperature of -6.1 degrees for several hours (with the machine working just fine!) and the machine restarted into all fans running mode after this.
I have tried both replacing the battery and resetting the PMU - which appeared to fix the fault for a few days, it then recurred.
The machine also will not sleep properly - in that it won't always wake from sleep and needs a power off and reboot - which sometimes occurs with all fans running.
Apart from that the machine works fine - all my software works etc even when all fans are running.
Any ideas as to the cause? I've not changed the hardware (except to replace the battrery when the fault first started) or software for over a year. Is it case of a failing logic board or could it be something else? Any ideas on how to resolve this?
Is there any problem in running the machine when the temperature monitor is showing flatline temperatures for all sensors - or is there a lower level system that will protect the machine should temperatures get too high (maybe by switching to all fans running?)

An update to my G5 fans problem - the problem got worse, with trouble booting the machine at all. It would sometimes take up to half a dozen attempts to get a chime and then a boot :-( Sometimes all the fans would come on after a few minutes, sometimes not at all day. Sleep mode stopped working completely. As the problem was getting worse and worse, I gave in a bought another, refurbished machine identical to mine, swapped over my disks, extra memory & SCSI card and everything on tha machine works just fine :-)
I may try to further diagnose the problem with the old machine later on.

New logic board, still boot problems with Turbo Fans

I bought a 2Ghz dual G5 from a guy on craigslist and he told me that the Geniuses at the Apple Store said it had a bad logic board. So I bought a brand new logic board from DVwarehouse.com, and installed it along with a new set of matched RAM from Crucial, a new HD, new PRAM battery, new video card and a new superdrive. The only thing original are the processors and power supply (and fans, of course).
When I start it up, after the chime it quickly goes into "turbo-fan mode", which I have read that means the Op Sys didn't load correctly. Many restarts later, I was able to reset the nvram in the Open Firmware, but that didn't seem to help at all. I also pressed the SMU button (according to Apple's directions), but that didn't help much either.
I've had a few successful boots, but always with the fans going full blast. I though that once I got Leopard loaded onto the HD, then it would calm down with a software update. But before I ever get that far, the G5 hangs. Sometimes the G5 will boot and access the HD but hangs soon after. Sometimes I can get it to boot off the Leopard DVD. But most of the time it just boots and sits there slowly spinning up the fans into turbo mode.
The few times it has booted to access the HD or DVD, the fans go turbo right away. Other times it will boot with a chime, but then it won't access the HD or DVD and I get noting on the display.
I should say that this behavior is almost identical to how it was acting before I replaced the logic board. But how can that be? It should be a new computer, unless the problem is in the CPUs. Is that very likely? How would I find out if the CPUs are bad?
I've been reading alot about the problems I'm having with this G5 and what I've been having seems to be very common. But I've run out of fixes. Is there anything I can do to fix this machine or is it just money down the drain?

my iMac 20" G5 experience since December 2004, even though I love this machine,it has gone through 3 power supply (661-3350) replacements and 3 logic board replacement since late 2004. Pretty crazy for a single machine but I still love it. The last logic board replacement did NOT fix my boot up problem, as I expected, and the genius finally agreed to replace the power supply and that fixed it. SO: My recommendation to you is "replaced the power supply" here is one place you can get one: http://www.dvwarehouse.com/Power-supply-180W-for-iMac-G5-20--100v-661-3350---614 -0353-----NEW-p-25613.html

MSI P55-GD65 - Problem with automatic fan control.

Hello.
I wish to share story of my fan speed controller.
Lately I've upgraded my machine to modern specs (look at signature) and I was quite happy about that.
It worked flawlessly for about week.
My H/W Bios settings was - CPU Smart Fan Target = 60°C and minimal fan speed 50%.
I was amazed how nicely GD65 maintained between heat and speed.
Yesterday, I've noticed that my fan is really quiet all the time, even when gaming (before it accelerate speed while hardcore gaming settings). I was quite content about that, until my computer crashed due to overheating while playing Battleforge match.
After reboot I've ran Intel BurnTest and HWmonitor. OH my, what was my surprise when I saw that fan speed is always 50% and do not speeds up when cores are heating up!
I started to checking things out. What I've discovered:
-(CPU Smart Fan ON) Fan is always at minimal speed given in BIOS. It doesn't accelerate even if CPU is burning.
-(CPU Smart Fan ON) Fan speed cannot be controlled by any program (like SpeedFan).
-(CPU Smart Fan OFF = 100% fan speed) Fan speed CAN be controlled by program like SpeedFan, which saves me from fan buzzing.
I've try to fix that by:
-Checking cables.
-Clearing CMOS.
-Updating BIOS to 1.6.
-Praying.
And still nothing.
My conclusion:
Fan speed cannot be change when Smart Fan is on, it locks fan speed at minimal speed given in bios.
Now I just hoping that this is somehow stock fan fault, new Zalman CNPS 10X QUIET is in delivery.

No problem here with Target 55° and Speed 37.5%.
Fan runs at 1330 below 58° and 2050 above which is max.
The CPU is running at 3050 MHz because of XMP 'overclocking'
Have reverted to BIOS version 1.3, due to XMP problems with other versions.

MSI CD53, i5 750 - Problem with CPU Fan Speed

Hello
I have problem with this counfiguration: i5 750, MSI CD53 Motherboard.
I Have processor overheating poblem. I noticed that processor easly can go up to 90C.
I check phisycal installation, and all its ok.
After that i check RPM of CPU FAN and i noticed that it cant go over 1000 RPM, so propably this is problem.
In MSI Control Center maximum i can set 1000 RPM.
I read that CPU FAN can go up to 3000 RPM.
Maybe i have something wrong set up in bios? What can i do with this?

Quote
CD53
Which board exactly do you have?
What is your current BIOS Version?
What kind of CPU-Fan are you using (3-Pin or 4-pin PWM (four wires) and which connector is it attached to?
What are your current fan speed/control settings in BIOS Setup?
Quote
I check phisycal installation, and all its ok.
Physical installation is one thing, but what about thermal paste (have you used a PROPER amount (too much thermal paste has the opposite effect))?
What about your case ventilation?
Quote
I noticed that processor easly can go up to 90C.
Please check the CPU's core temperatures with CORE TEMP, REAL TEMP or HW-MONITOR!

DOES ANYONE HAS A PROBLEM WITH A FAN NOISE LIKE A METAL BEARING

I want to know if there is a problem with some of you that have a 20 inch early Imac I got this imac last june and now I begin to hear a hizzing noise like if it was a fan bearing or something.

The drive is in the area where the vent grill is above the plug. There is a very low level disk "activation" noise (sort of a faint ticking type of sound) whilst it is working but then stops, where as the fans again very low noise can be heard all of the time - just. I sit about 650 to 700mm from the machine.
The drive is only a manmade item and occasionally one will start to fail early in life. Today is unlike the old days where a vari-speed floppy drive could need changing every month if worked in a commercial environment and a hard drive wasn't much better.

Problem with processor fan.

Hi, since a few days ago the processor fan is not starting when I turn on the laptop, it just starts when I open any windows user session, it used to work fine, suddenly changed and I don't know how to fix it, also when Is not in "High performance" mode the fan just doesn't start till I go to energy options REactive the "Max performance" option in cooling mode... I'm sorry for my poor explanation, my english is not very good, but I hope is enough to get a little help.
Thanks.

The fans on laptop computers are thermostatically controlled so they don't turn on when the computer is first turned on. "Thermostatically controlled" is a fancy way of saying that the fans are turned on and off by the heat of the computer. Once the computer gets hot enough the fans turn on. This is a power saving feature to help save on battery power. When the computer's power setting is set for Performance, power is no longer a problem and the fan will come on more quickly and frequently. I have seen where the Bios has been changed to change the fan's heat settings, so you may want to make sure that you have the latest Bios. If the computer is not getting too hot or shutting down because of heat problems, I would not worry about the fan not turning on at startup.

Problems with RPM fans [SOLVED]

Hello. I'm a Spanish user. I don't speak very well English, I'm sorry.
My problem: PWMconfig don't detect modules:
$ pwmconfig
# pwmconfig revision 5630 (2009-01-29)
This program will search your sensors for pulse width modulation (pwm)
controls, and test each one to see if it controls a fan on
your motherboard. Note that many motherboards do not have pwm
circuitry installed, even if your sensor chip supports pwm.
We will attempt to briefly stop each fan using the pwm controls.
The program will attempt to restore each fan to full speed
after testing. However, it is ** very important ** that you
physically verify that the fans have been to full speed
after the program has completed.
/usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed
This is my lm_sensors:

Newbie having problems with noisy fan and high CPU usage in Activity Monitor

I am new to the world of Apple and have got my hands on a hand-me-down PowerBook G4 version 10.4.11. It works fairly well for everything but the Internet.
One of the first symptoms i noticed was that watching stuff on youtube was slow and jumped a lot. I checked a few things out and looked the CPU usage in activity monitor and this was about 80% to 100% when on youtube or even moving from page to page. I'e tried loads of stuff including repairing disk permissions, emptying caches and relaunching finder when the preferences file is on the desktop (not really sure what that was supposed to do).
The next thing I discovered was that if i disconnected the laptop from the mains and played youtube and some other applications the whole thing would go into sleep mode very quickly. I have got temperature monitor downloaded now although I already know it is getting very hot.
PS when it heats up the fan turns on because I can hear a whirring sound...
Would really appreciate some insight into this as it seems to be a good runner otherwise.
PS2 I have loads of free space left in the disk usage tab in activity monitor.
Big thank you in advance

Virtually no G4s are dealing well with web video anymore. The video technology used by modern developers puts a huge strain on a G4 processor. As this a choice made by coders, there is not much you can do about it. Some people suggest adding RAM but the effect is marginal considering it's the processor that's taxed.
Notebooks get hot. The fans in my 1Ghz 17-inch PowerBook from 2003 kick in between 130 and 140°F. The danger point is not until in the vicinity of 100F so don't sweat it to much. Make sure you do not cover the case bottom by setting the computer on a thick cloth placemat, pillow or other bedding item, or on your lap without a lapboard. The bootom of the case is part of the heat dissipation system and needs air under it to work
A lot of PowerBooks have, by now, lost some or all of their "feet" that gve a little space under the case. Don't bother looking for official replacements--get the silicone door/drawer bumpers from the hardware store that stick on. I found some about 3/16" thick that let more air under my PB thatn the mostly missing originals.
The next thing I discovered was that if i disconnected the laptop from the mains and played youtube and some other applications the whole thing would go into sleep mode very quickly
Your battery is likely dead from old age. Batteries only last about 2-3 years. You are seeing a sign of the battery lacking sufficient remaining capacity to run the computer. Get this utility:

Problem with Sensor fan 3 and 4 (P67A-GD65

Hi all :D.
I had buy 1 week ago a new P67A-GD65 motherboard but i have found a problem .
Today, i have connected my 4 fan in three different slot fan.
When i look with EFI the rpm of the fan,i can look only CPU_FAN SYS_Fan1 and SYS_FAN2 but not for SYS_Fan3.
Where is the problem? Sensor? Or what?
I had try to use AIDA64 and SPEEDfan but same problem

Not all Fan headers support fan monitoring & fan speed adjustion. That is not a bug but rather the lack of a feature.

This is my first time using a 1.1 Theme for a photo blog, and I'm having an image problem that I can't find a way around.
My image looks fine in the actual blog entry page, but back out on the main Blog page, it is cropped into a widescreen shape, cutting off the top of the image (and peoples heads in the process!)
I can see no way to edit this photo mask out on the main blog page in this theme. Am I missing something, or do I need to live with it?

Nope, that's just how that template works!

Startup problem with notebook not booting. complained of primary internal (601) problem

Repeated booting sequence and notebook not booting fully to Windows. Complaining of battery internal (601) error.
How do i get my notebook to complete the startup process without changing the battery?

Hi,
The 601 error does mean you'll need to replace your notebooks main battery - you can find more details on battery error codes Here.
While the battery is still connected, even if you clear the cmos, the error code will simply generate again so in the meantime, you should be able to avoid the error code if you shut down the notebook, unplug the AC Adapter, remove the battery and run the notebook just on the AC Adapter.
