Regarding to .. how will i remove the case to remove the cooling fan?

Ok, on a laptop you need to get some cups and label them to put the screws in so you will know where they came from. Remove the Power Cord, Remove the Battery then start removing all the screws from the bottom of the laptop. Then remove all the devices from the bottom of the laptop such as the hard drive, the memory, dvd/cd drive, wireless card, etc. Take note of how the wires are on the wireless card, those are the antennas.

Look inside the battery case, hard drive case, memory case and dvd drive slot for screw. Some screws on the bottom case in inside of some of the device cases might have the icon of a keyboard next to it. Those screws hold the keyboard in place.

Turn the laptop over, remove the strip that is just above the keyboard but be careful because a cable might be attached to it. Then remove the screws that hold the keyboard in place that are under where the strip was and gently lift the keyboard out because there is definitely a cable under it.

Next you can remove the screws from the lcd hinges at the corners and lift the lcd screen off, also note that you will have to pull the antennas cable and the lcd cable when you remove the lcd.

Next start removing any screws that hold the palmrest in place. Take note of any cables that are attached to the palmrest and remove them then lift the palmrest off.

Next start removing any screws you see that hold the motherboard to the bottom case, then lift the motherboard out an start replacing the fan.

A digital camera to take pictures will be most helpful to refresh you memory of where things were.

I have installed my abit nf8-v2 motherboard into my computer but i can not get my computer to power on. LED 2 is turning on but not LED1

Please verify that you have completed the following:
  1. Connected the cables from power supply to the motherboard
  2. Connected the processor fan power connector
  3. Installed the memory correctly
  4. Connected IDE/Sata cables correctly
  5. Processor installed correctly with fan sitting correctly

Koliki je broj obrtaja RPM ventilatora A38001-001; kakve lezajeve ima; kako se odrzava (cime se podmazuje) i koliki mu je ukupan vek eksploatacije u casovima rada hours? Thank You for Your`s Assistance,...

No, that fan is cookin'! > Spinning too fast.

The Sanyo A38001-001 from Intel, is only designed to spin in those RPM's when the Processor is REALLY Hot!

Usual RPM's are around 1750 to 1850.

A) Did you just buy and install this Heatsink/Fan combo?

1) If so, did you thoroughly clean the top of the Processor's case?
Used a scraping implement like a plastic credit card to scrape off the old Thermal Paste, and then used Q-tips dipped in Isopropy Alcohol?

[ Also know as Rubbing alcohol. 91% is best, but 70% will do in a pinch. Make sure it's dry afterward though. {91 percent alcohol, 9 percent Water, or 70 percent alcohol and 30 percent Water)

The Q-tips dipped in alcohol will wipe up the gooey mess of thermal paste. Usually takes quite a few Q-tips.

Isopropyl Alcohol is EXTREMELY FLAMMABLE!

Use in a well ventilated area with No sparks or flames present.

2) You did apply Thermal Paste, and correctly?
One small drop about the size of a large pea, in the middle of the top of the Processor's case.

Then set the Heatsink/Fan combo on top of the Processor, and tighten the screws down in a Criss-cross fashion

3) Tighten one screw down one turn. Go to the Opposite Corner, tighten that screw down one turn.
Skip over and tighten the other two screws down one turn as detailed above. You are tightening in an X pattern.

Make SURE the Heatsink's bottom is flat and level on top of the Processor's case.
If it is tilted even slightly, the heat transference won't be worth writing home to Mom about.
The Processor will overheat, and the fan will spin at high RPM's.

4) Is the Fan cable (Wires) plugged into the motherboard tightly? Plugged into the correct fan connector on the motherboard? (CPU_FAN)
Does the motherboard's Cpu fan connector have the same number of pins needed, as the fan cable connector requires?

B) If this Heatsink/Fan combo, (Sanyo A38001-001) has been installed for quite some time, check to see if the Thermal Paste has dried up, or is drying up.

Since 2004?
Yep, you better pull that Sanyo A38001-001 off, and check the Thermal Paste.
Computer unplugged from power, OBSERVE Anti-Static Precautions.
A Processor is the most susceptible hardware component to Static shock.

Clean the Processor and bottom of the Heatsink as stated above. Properly apply fresh, new Thermal Paste.

Example of Thermal Paste. (Maybe there is a 'Mom and Pop' computer store near you, that you can buy a one Processor application, for around $2)

Check for a loose Cpu fan cable connection.

Make sure the Heatsink/Fan combo is seated tightly on the Processor.

I have a dell xps 1210 the cooling fan stopped working I replaced it with a new one and it still won't work

The motherboard may have several 3-pin connectors, for installing fans in different places. Connect the cooling-fan to one of those "alternate" connectors, and start-up your computer, to see if the fan spins.

Try a different power-supply.

Try both the "old" and "new" cooling-fans in a different motherboard, to see if they spin at all.

Sister, Son and I all have the same model Sony Desk Top Computer. Model VGC RB57GY. Computers are overheating and showing overheating error and shutting down. Mine now is shutting down after even a...

May I ask what Temperature you are referring to, and where you are looking for the temperature at/in?
Do you have external software that reads these temps?

Motherboard temperature?
CPU (Processor) temperature?
ATI Radeon X300 graphics card GPU temperature?
(Graphics Processing Unit)

CPU temp:
What Processor is installed, and what is the maximum thermal limit for it?

Intel Pentium D Model 820.

64.1 degrees Centigrade, or 147.38 degrees Fahrenheit.

Checked the thermal paste to see if it has dried up?
Even if it hasn't, cleaning the bottom of the Heatsink, and the top of the Processor's case, and applying fresh, new, thermal paste is the way to go.
After a certain amount of time, thermal paste loses it's thermal conductive properties.

If it is a thermal pad, remove it, fly it out the window. They're junk.
Use fresh new thermal paste instead.
(Be sure to observe Anti-Static Precautions)

Fans are all working fine.
According to whom?
The tech?

Not doubting your abilities for one second. DO doubt the many 'techs' who profess so.

Computer case open, observe the Processor Fan. Ensure that is is spinning at all times, and not intermittently.
Also ensure that the fan is spinning at the correct RPM's.
(Revolutions Per Minute)

Same with the computer case fan's, Front and Rear.

Computer clean inside?
1) Processor fan?

2) Heatsink?

3) The area of the motherboard you can see with the computer case open?

4) The area Behind the motherboard, that you Cannot readily see, without removing the motherboard?

5) The ATI Radeon X300 graphics card?

6) The Heatsink on the Northbridge chipset?

Check the cable connection of the Processor fan to the motherboard, and the computer case fans, IF, they (Case fans), have three wires, AND are connected to the motherboard.

One wire is for Power
One wire is for Ground
One wire is for a sensor that detects when the fan should speed up.

Processor fan spin freely? Computer case fans? Feel like they/it, may have a bad bearing?

Let's diagnose together, and see if we can solve this.
If all of the above reads like a foreign language to you, I will explain step by step, and guide you.

Truth be told my friend took it apart w/out the service manual and put it back together and now it overheats. The original problem is the techs at Staples said my mouse went crazy and still is.

This would be a hard one to trouble shoot without the computer in front of you. Depending on the manufacturer of the motherboard there is usually two or three fan power plugs on it. One is marked CPU and is usually on the top edge of the motherboard, the CPU fan has to be plugged in there, the others are usualy marked CHAS, SYS or MB for the accessory fans in the front of the computer, if it has one, and sometimes another for a fan in the rear of the computer. These plugs usually have three pins each. two wires for power for the fan and an RPM wire for the motherboard speed readout on the computer screen. As for the mouse going crazy, try and uninstall it and then reinstall the drivers. This will sometimes correct the problem, or buy a new mouse, they are cheep. If that doesn't cure the problem then there is something more seriously wrong with the system. Good Luck, RAC

Check to make sure the CPU fan is plugged into the motherboard CPU fan power pins. Should be a 3pin port on the motherboard near the cpu with a white piece of plastic on the one side of it to show you are to plug in the cable correctly.

See if the fan spins at all on start up, or even when the computer is off, spin it with your finger and see if it gets hung up anywhere while it spins.
