Intel Cpu Fan ReWiring

I have an Intel Processor Fan that I do not use anymore.
It used to be used for my computer, but now its just lieing around.
I would like to use this fan without a computer.
On the fan it says
12VDC 0.60A
I cut and stripped the fan wiring and it has 4 cables coming out of the fan.
A blue cable. A yellow cable. A green cable. A black cable.
Please help me find out how to wire this into a battery so that I can power it.

Here is the pinout for the wiring:

Pin Name Color 1 GND black 2 +12VDC yellow 3 Sense green 4 Control blue

In case this doesn't show...Black is Ground and Yellow is +12VDC.

Not sure if it will work w/o a Sense (Green) and Control (Blue) line though.

I don't know technical terms but there is a 4screw x that holds the sink to the mother board just to the right of the x is a small square over a chip is the square super to have a pad on it or no pad and...

Let me see if I can decipher what you have stated killa_klowns, and offer a solution.

1) The Processor has a Heatsink on it, or a Heatsink/Fan combo. Depends on what the computer manufacturer designer wanted to implement.

{Some computers have a Heatsink/Fan combo sitting on the Processor.
Other computers just have a Heatsink sitting on the Processor, and air is provided by a Front computer case fan pushing air through a plastic cover onto the Heatsink}

Typical design for a Heatsink/Fan combo (Stock design. LGA 775 processor socket. Also, not a gamer type of rig),

Photos showing typical Intel Pentium 4 processors. Shows the top of the Processor's case that the Heatsink sits on,

Where the headings state > Specifications - Pictures (5) - CPU ID (1) - Comments (15),
click on Pictures (5)

Thermal Paste should be used on the top of a Processor's case.
If there is a Thermal Pad, take it off, and fly it at the cat.
They're JUNK!

[ Always Thoroughly clean the top of a Processor's case, and the bottom of the Heatsink, before applying fresh new Thermal Paste. Same thing for every chipset.

> Observe Anti-Static Precautions A Processor is the most susceptible hardware component to Static shock.

Use a plastic scraper to clean the top of the Processor's case, and the bottom of the Heatsink.
I use an old credit card.

Then use Q-tips dipped in Isopropyl Alcohol (Rubbing alcohol) to clean the top of the Processor's case, and the bottom of the Heatsink.
May take several Q-tips dipped in alcohol. Usually a gooey mess.

Isopropyl Alcohol is EXTREMELY FLAMMABLE!
Use in a Well ventilated area with No sparks or flames present ]

The next chipset in line to use a Heatsink is a Northbridge chipset.
Termed Northbridge, for one, because in relation to how it is sitting on the motherboard, it is to the North of the motherboard.

On the motherboard the Northridge chip sits below the Processor.

The Northbridge chip may, or may Not have clips which hold the Heatsink on.
When no clips are used, > Thermal Glue is used to hold the Heatsink on.

{The motherboard chipset is the Northbridge chip, and the Southbridge chip.
Note* This info does Not apply to motherboards that support the Intel Core i3, i5, i7, or i9 processors}

The Super I/O chipset does Not use a heatsink.

Tell me what the motherboard manufacturer name, and Model Number is, and I can give you more detailed info about that motherboard.

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.

Have any further questions please post in a Comment.

Intel PC wont boot past startup and keeps shutting down unless I disconnect the cooling fan, let it start and then reconnect the fan


might have to get a higher wattage power supply,
the initial amperage draw plus everything else may be causing the stock power supply volts to dip past the limit
maybe download the intel active monitor and study that, or hook up a voltmeter and watch the output at startup.

good luck with your toy

Noisy fan

You need to replace the fan. Measure the fan you have now and buy one the same diameter. Then remove the old fan and put in the new fan.

System cooling problem

Hello there,

No this is normal for a fan to speed up or slow down. It all depends on what the CPU is doing. FOr example, if its doing lots of graphics (3D gaming etc) then it gets hotter and the fan speeds up to cool it.

If your worried you can use a heat monitor to check if things are ok. You have an intel motherboard?? If so go here to download a monitor:

If your unsure about the motherboard (or you dont know if you already have a heat monitor) then try this one:

I hope this helps you, and if it does let me know by rating this answer.
