    You can get a fan that has a 4 pin molex connector on it and it will plug into your power supply connector.

Not so much a reroute as a different source. Do I assume you have perhaps a smaller 3-pin connection and would rather go with a larger 4 pin (or vice-versa)? There are splitters that will let you run a second 4 pin off of a single connection (about $5). If you want a 3-pin, there will be a space for that on your motherboard. Ensure when buying a new fan that it has the proper connector if it doesn't come with both.
If this isn't what you were looking for in an answer, could you explain what it is you're trying to do? Thanks

  1. Check your computer is getting power, (reconnect power from outlet)
  2. if power is ok, then open your computer cabinet, disconnect motherboard power (24 pin), then make short Green and Black wires and check power supply fan is working or not, (Switch off computer when disconnecting)
  3. if fan is not working replace power supply (SMPS) and check (working fan means SMPS is ok, but in some occasions Fan may work in defective SMPS )
  4. if the power section is ok you need check you mother board

It if is a three pin male "receptacle" with a tab on one side and open on the other, it is in fact a fan connector. Most motherboards have them labeled right on the motherboard as Chassis, CPU, etc.

I can't get it to turn on ; when I pess the on switch, the blue light does not come on


try pull out the ac adapter and battery. Hold down the power button for 30sec-1min. Reconnect ac adapter and see if you can power back on.

Test your ac adapter to make sure it's not dead. You can get instructions on how to do this on http://www.bootmylaptop.com

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.

CPU fan turns for a few seconds and stops, pc will not turn on. Have tried a good PSU, same issue. Removed all connection to motherboard apart from 20 pin, 4 pin power + cpu fan and PW switch: same issue.


1. First of all Remove dust from your CPU fan and try again if issue has been not resolve

2. Second test your SMPS by the help of Green & Red wire. In case fan is turning properly it mines your SMPS is ok

3. Third & last kindly replace your SMPS For the same.

I am in the process of setting up a barebones VBBI-2N7300 (installing Windows 7 on new sata drive) and noticed that the clear fan on the side and the large muffin fan in the rear are not on. Please advise....


Hi,
There should be 2 male fan connectors on the motherboard, one is for the CPU fan and the other is for the case or system fan, this will marked on the motherboard and are usually white in colour.
The case or system fan are not usually temperature controlled but in some cases you can adjust the speed in the BIOS, the CPU fan however is temperature controlled.


Regards.
