Windows 7: CPU Heatsink/Fan - No Power

CPU Heatsink/Fan - No Power

I am running a Gigabyte GA-MA770-UD3 motherboard with a brand-new quad-core AMD which I am building for a friend.

Now I know this to be a motherboard problem, because I have interchanged other heatsink/fans and they also are getting No Power from the motherboard.

So what I need is an adapter for a molex that will be male to the heatsink female (sexy, eh) - 4 pins (blue, yellow, red, black).

Don't wanna mess this up. Any suggestions as to which adapter to purchase?

See snippet (It's the CPU fan that's not working. System fan is OK)

If the motherboard is faulty, why not return it? What am I missing? If the build was for my friend, I'd want it perfect not some cobbled up machine that the user can't adjust the fan control for the CPU.

Ever RMA'd a Gigabyte motherboard?

For what it's worth I have it on good source that Gigabyte actually developed the game Three-card Monte.

Nope, can't say I have. Wouldn't own one anyway. Return it to the vendor.

The CPU fan is probably the most important fan in the whole system. It's controller is such that it reacts to changes in temperature of the cores more rapidly than the sensors for the rest of the system. I would think that you could smoke a CPU pretty fast. How would that look to your friend?

Can you not RMA through the seller rather than direct to Gigabyte?
Gigabyte's customer service is dissgusting, Well it was for me anyway. You think Gigabyte are bad though you should have a look at the rog forums n read some of the horror stories about Asus :O

If the board can not read the cpu fan then it could also cause other problems. If your friend tried to OC the CPU then it could fry the CPU. RMA it to vendor for a replacement. Don't let the vendor fob you off telling you to send it back to Gigabyte.

A modern motherboard is not supposed to boot without a CPU fan plugged in. So bypassing the header will only complicate the problem.

Do you have a micrometer to test the pins for voltage with? You could test the other fan headers too.

You guys are all correct. If the CPU power-out is not working, well then other parts of the motherboard might also not be working correctly. I've owned both the UD3 and UD5 Gigabyte boards. I bought into their 2 oz. of Cu nonsense only to find out their motherboards are all junk. Over at OCN we discussed these problems at length in the GB forums.

When you RMA a board to GB, they play the Three-Card Monte game. I always mark my RMA boards in a place they would probably never find. And what does GB do? Well, they send me back a completely different board that they claim I static-burned because I was careless. Different board completely + I always use vinyl gloves and a grounding strap. In short, GB is hands-down the most dishonest company I have ever experienced. Think I'm being unfair? Well, just read through the GB forums over at OCN. I'm not the only one they have duped.

So it looks like I will be tossing the GB UD3 board and purchasing an ASUS board (got 4 of them in operation now and have owned many others in the past - ASUS = Reliable.)

Any recommendations on a super cheap AMD ASUS board?

If it was a recent purchase with a credit card, you bet I'd go directly to the vendor for a replacement board. Let them hassle with the OEM. A motherboard must meet certain merchantability laws. (...that something that is sold will be merchantable and fit for the purpose for which it is sold.) If it's DOA, it might as well be a box of loose parts. If it's a warranty claim after being used, then that's another matter.
