Fan - Mine not working (do I need to switch it on)

the perfromance on my MacBook Pro is VERY slow - and I now realize it could be because the Fan is not working - Does it need ot be activated or something?
This is so frustrating, We have 8 macs in our studio, 6 of which have had to be replaced due to something faulty on them......I hope this isn't mac replacement 7!!

Fans turn on automatically when the CPU gets to a specific temp. they don't need to be turned on manually.
When you say your MBP is running slow:
a) generally or all programs?
b) how much RAM do you have? And is it OEM or 3rd party?
c) is it networked?
Your problem could be a bad fan, bad temp sensor, or could be you are running programs via Rosetta. Give us more info and we could probably isolate the issue better.

HSTNN-E06C - Fan is not working, need a replacement.

Hello.
I have a HSTNN-E06C laptop. It seems that my CPU fan does not work anymore.
Before I got my laptop disassembled, I would like to prepare myself with proper components. I would like to ask You what is the FAN product code, so I will be able to order a fan replacement?
can you also provide me some service manual, which will help me to take the laptop apart in proper order.
Fan replacement should not be any problem for me, so I really count on you, guys
Thanks in advance.
This question was solved.

If it is the fan that is you're having problem with, you can replace it. HP doesn't provide cooling fan alone as spare part.
You might want to contact the online sellers mentioned above or your local stores with the part number & ask about it.

Upgraded RAM and now Fan is not working.

I have upgraded my RAM to 2GB. (using video guide) Everything appeared OK, but the mac mini was overheating and shutting down after 10 - 15 minutes. It appears that the cooling fan is not working, as far as I can tell. I have checked and cannot find any loose cables, I have tried powering up with and without the fan control cable connected (next to the battery at front of mac).
I have tried the hardware test but this is OK. I have tried some software downloads for monitoring the fan speed, but these appear not to work.
Is there a cable or connect that I should be looking at? DVD, sound and all else seems OK. The memory passes all ram tests.

I think you are referring to the fan control lead, which attaches at the front of the PCB near the battery. Is this the case? I have read that this only controls the speed so you don't have to attach the cable, in fact it suggests that if you leave this disconnected the fan should run at full speed.
This is the only cable that I needed to disconnect, and have tried with it attached and disconnected, with the same issue. I am thinking that the fan is dead, or is being stopped by the magnetic tiles, I guess these are used to create a magnetic field that forces the blades to spin, so I guess if one of these has come away from the unit then it may not work. I can see that I can get a replacement fan for about $29.
Can anyone confirm that these magnetic tiles are integral to the working of the fan?

Fan is not working well of a pavilion g6

when starting up my laptop, it reports that my fan is not working well and when it remains on for about 10minutes it starts to be hot at the position where the fan is located. the problem just started.

Hello
could you sense the fan is running by hearing and hot air blow out from air vent?
1) if fan is running and running faster when hot, it means fan is working. please check if anything block the air vent or air intake. only Air can flow freely, it can cooling down the CPU.
2) If Fan is running and air vent is not block and unit is been used long time, maybe the dust. if you have skill, please clean dust, it need remove some cover to disclose fan/heatsink.
3) update BIOS to latest. of course Fan need to replaced if it is not run, but the running Fan usually don't need to be replaced.

HP Elitebook 8470p - from battery the fan is not working

Hello Everybody elitebook Expert!
My laptop config in short: i5-3320m 2.60GHz with integrated graphics Intel HD4000, 4GB Ram.
I don't like the elitebook 8470p cooling system and i can't see the normal reason of the machanism.
So, there is no problem when the laptop is on AC power, the fan is on and works well and this is ok.
But, i have problem when the laptop is on Battery because when the laptop is in idle mode the fan is not working but stay.
Only starts then just when it attains the 55 degrees. This is not good, moreover it is bad for me, i dont like it because it is warm.
I want the ventilator to work so when the machine is on AC power everytime on Battery too.
In the BIOS there is no option for that and i can't see why...
Plase help me! I need a program what can turn on the fan when the laptop is on battery or a tweaker or something else i don't know what but i need something.
Aida64 says: motherboard name is: HP 179B
BIOS type is: Compaq EFI
BIOS version: 68ICF Ver.F.32 Date: 2012/05/12
(I know that there is a newer BIOS but i don't think so that there is an option in the new that can handle the fan on battery mode).
(Sorry for my English please).
Ákos

Thanks for the question Akos,
I understand that CPU FAN does not work on battery mode in windows mode however it works in BIOS mode.
firstly, as you know BIOS has control over CPU fan and CPU thermal table - however OS has better thermal managements. once PC is up, BIOS information and thermal control is handles by OS. to trigger a change it has to be still routed through firmware only however instructions are based on the BIOS thermal table and windows power management.
we know the thermal management of windows is better than BIOS and best to provide you best battery performance. so in BIOS CPU fan may be not mostly spinning all the time but in windows its more effective.
one example for the same is, when you update BIOS on your PC or we-write a BIOS - CPU FAn will be running at full RPM during the process because windows does not control the CPU fan at that time due to update/change process.
its completely normal that you see most of the time CPU FAN is off or spins for a very minimal time. if its always off that means there is something wrong, however if its seen off on battery in windows - its ok. i do not think there is anything wrong here.
if you want to have the FAN run always, that means you need to run your PC at a poor/bad thermal table. which i do not think possible with windows 8 platform because its largely looks like a mobile focused(better battery run time) platform.
you may try installing any of the older (prefer non-windows OS) to check. however its not recommended. because it may result in a damage to hardware too (if a non-supported OS used).
Hope this helps... Good Luck !!!!!

WW

Intel 865PE/G fan does not work

I have a 865PE Neo2-FIS@R Motherboardand the Intel 865PE/G fan does not work. Lately my computer has been crashing after some video intense programs. Could the problems be connected. If so does anyone know how to fix/start the fan? Is there anything in the bios? Any ideas would be appreciated.

Thanks x

You can upgrade to iPhoto '11 with OS X 10.8.5 by purchasing an iPhoto '11 DVD from Amazon, eBay or other source - or you can upgrade your OS to Mavericks for free if your system meets the requirements and then purchase the upgrade to iPhoto '11 version 9.5.x from the App store - in either case backup first in case of problems

HT3231 transfer files to my new iMac system 10.8.3, 9 pin firewire. Apple sold me FireWire 9-6 with a Thunderbolt to FireWire Adapter. This will not work, do i need a different cable?

I have a G4 with system 10.4.11 and a 6 pin firewire trying to transfer files to my new iMac system 10.8.3, 9 pin firewire. Apple sold me FireWire 9-6 with a Thunderbolt to FireWire Adapter. This will not work, do i need a different cable?

Apple Thunderbolt to FireWire Adapter
Then it sounds like the FW800 to 400 adapter just gets in the way. You don't have FW800 case? on my MDD G4 I added and used FW800 controller and cases from OWC and Sonnet.
