Fan Problems (concerning 3/4 pin connectors)

Hi

I recently built a gaming PC with 3 fans for cooling - one 120mm at the front, one 120mm at the back, and one 120mm fan blowing over a Scythe Ninja.

The problem is, my mobo (Asus M3N78-EMH HFMI) only has one 3-pin fan connector. This leads to two problems:
1. I can only have one fan running (naturally I hooked up the CPU cooler).
2. I get a boot error - No CPU fan detected!

Is there a way of getting a 3-pin 120mm fan running off a 4-pin CPU fan mobo connector?
I could live with 2 out of 3 fans.

Thanks in advance for your help
 
You should be able to just put the 3 pin fan in the 4 pin connector with 1 pin unused, the fan will still spin but will not be speed controlled by temperature like a CPU fan

Plug your remaining fans directly into your power supply.

To do this you must buy adapters. They are really cheap £1 or so (in theory about $0.70). They basically plug into one of you 4 pin molex adapters and splits to another 4 pin molex (so you lose nothing) and a 3 pin fan adapter, like the ones on your mobo

Sounds great, what are they called? (So I can search for them easily).

And I'm UK so it would be £1 (or w/e it costs). I'll have a look on Ebuyer, or go to me local PC shop.
 
I have just found this, i didn;t know they made em, but here we go

That is purely for price, i couldn't find a seller with picture (google for picture), but i will explain now:

It is a 3 pin fan splitter, so it goes into your fan socket on your keybaord and splits to 2 seperate fan cockets, so you can have 2 fans off of 1 socket. Now, how useful this would be, i don't know because you need 3 fans off the 1.

for the molex ones:

the second one is from a UK site, so shipping will probably be cheaper. It is the 7th one down on that link, Power splitter 5 1/4" male to female and 3 pin case fan is what it's called.
 
Not sure if this helps but the picture I found of the board shows 2 fan connectors,
not just one. Although you would know better if does or not. I realize you'd still be
one short, but also one closer to your goal. =D

This is a screen shot of the model board you listed.
