Hi:
An option for you is to just purchase a cheap adapter to plug your case fan into a unused power supply plug, such as one that plugs into a hard drive or optical drive.

Displays momentarily and asks for CPU fan connection. I have changed 4 fans and still get the same error message and the display goes off.


You're sure you have the cpu fan connected to the correct socket? sounds like it's not connected, or is connected to a different socket. Does the fan turn?

How Can I replace A Blown Fan header On my Mother Board. It's weird The three pin fan does not work in the three pin spot but when I ug it into the 4 pin header it works. The 4 pin fan does not work on...


If you have to ask about the difficulty, then you probably lack the skill to do the job. The 4 pin fan header is usually for the CPU fan and the 3 pin one is usually for case cooling. The extra pin is for speed control of the CPU fan (to cut noise) If the 4 pin fab fails on the 4 pin header then the fan has probably failed, because the 3 pin one works.

I replaced my power supply and don't remember where the connections went


Not too much way you can go wrong. There's a 20 or 24-pin connector which plugs into the motherboard in only one place. There probably is a 4-pin connector and that, too, goes into the motherboard (in a socket near the CPU). The other connectors are power connectors for you hard drive and CD/DVD. That's about it.

How do i connect the fan to the power supply?


Most fans use a standard 3-pin plug, and if you look closely at the motherboard you'll probably find a spare 3-pin header or two marked "case fan" or "system fan" where it will connect. Most motherboards have an extra header or two for additional fans. Note that this is not the same place where the CPU fan plugs in. That connector should be used for the CPU fan only. If your motherboard only has a single system fan header (common on the small micro-ATX format boards used in most consumer machines), and it already has a fan connected, you can get an adapter like this one to split the power connection.

How do I find a manual for the ULT40278. I'm trying to figure out you would connect 2 fans when some motherboards have only one fan connection?


Motherboard fan connectors typically use a small 3-pin which looks like this: zero_awake.jpg
the left connector is a female connection (the side with 3 holes) the middle and right are male connections, has 3 metal pins:
  • Black: GND (ground)
  • Red: +12VDC or +5VDC (12V or 5V DC - direct current)
  • Yellow: Tachometer signal (used to read fan speeds)
NOTE: Wire color may vary, and some fans or motherboards may control fan-speed.

Some fans use a 4-pin connection, which is generally a CPU fan connector but not always:
zero_awake_0.jpg
This pictures a 4-pin connection, but may look different from other 4-pin connections because the wires are covered in a black sleeve, which keeps them safe from harm and to reduce potential negative affects on airflow created when there are lots of loose wires inside a computer case.

zero_awake_1.jpg
This photo shows a 4-pin connection attached to a motherboard next to a 3-pin connection in a motherboard. While it is not recommended in the case of the CPU's fan, in the case of other internal case fans with a 4-pin connection, it is possible to plug them into a 3-pin connector of the motherboard, but the ability to control fan speed, which is controlled in the 4th pin will be lost.

Though sometimes computers have a way of controlling fan speed on a 3-pin or 4-pin connection even without the 4th pin, such *** voltage regulation and reading tach. feedback. These things are typically things a general user doesn't need to worry about unless their computer is running particularly hot and causing trouble.

In which case, it might be worth investing some money in a fan controller, which takes a power connection, several fan connections (varies based on the controller you get) and gives you the ability to control fan speed externally on your computer case. My controller has nice dial knobs, though some "fancy" controllers have a display and up and down buttons. (Fan controllers would be at your own discretion in terms of price, you can get them cheap all the way up to seemingly ridiculous expensive)

In the event of not having enough 3pin or 4pin connections on a motherboard, it is still possible to add case fans by way of 4pin molex connections:
zero_awake_2.jpg
A female molex connection

zero_awake_3.jpg
A male molex connection

Some case fans run exclusively through these connectors, others have a combination of a 3pin (or 4pin possibly, though I've never seen this combination) and a 4pin molex connector. In this case, the molex connector can connect directly to a cord from the power supply and run the fan. It is possible to run case fans without having them connect to the motherboard at all! Which makes it possible to connect more fans, with less available connections for your fans on your motherboard.

If a fan is a certain connection (any of the 3) and you need to convert it, for example:
  • a 3pin to a 4pin molex because your motherboard doesn't have enough 3pin connectors for all your fans,
adapters are available to change one type of connection to another, at many online retailers (such as newegg.com, amazon.com, or other electronic supply retailers) and some retail stores, Best buy might have something, though you'd have a safer bet at a store like Micro Center which is more specialized for PC building or an alternative PC/electronic store.

To ensure you solve your problem, just be sure to familiarize yourself with the motherboard you are planning on buying (or have) and the fans you plan to have inside your computer. It can be a bit more work to check the specs on the fans and motherboards, but a little work saves hours of headache later.

I want to know the international colour codes for wiring a three pin plug please


The colours vary from country to country.
In the UK and Ireland the colours are
Brown = Live, (Goes to the pin connected to the fuse, on the right if the longer, earth, pin uppermost)
Blue = Neutral (Goes to the pin on left if longer, earth, pin is uppermost)
Green and Yellow = Earth (Goes to the longer pin)

In the USA and Canada
Black = Hot (Goes to the pin on right when the long round,earth, pin is nearest the floor)
White = Return and (Goes to the pin on Left when the round, earth, pin is nearest the floor)
Green = Earth (Goes to the longer round pin)

Basic rules case wiring. The color black is considered ground -. Power wires + can be any other color including stripped wires. (This is standard but case Mfg change to their own specification).

Pin 1 is + power for LED Hard drive green LED, Pin 2 is -/ground for Hard drive LED.
(Pin 3 is + power for LED Hard drive yellow LED, Pin 4 is -/ground for Hard drive LED).(See more options on pg. 47).
Pin 5 is + power for case On/off button, Pin 6 is -/ground On/off button.
Pin 7 is + power for Reset Switch, Pin 8 is -/ground for Reset Switch.
Once positive & negative pins has been located each connector follows in suit.

The Intel RC440BX front case connector is in an odd location.
The user will find it hard to connect front case LED connectors while the board in installed into the case.

Good Luck!

Normally on the board there is silk printing to state what connection goes where. Also on the black connector i.e. power LED there is a small arrow that goes to pin 1 of the POWER LED pins.

Hope that was any help thanks J
