Need some direction

They mean the same thing, and can be controlled by the mobo.

I was told that buying just any case fan with a Black, red, Yellow wire combo could ruin my MoBo and i would need to find a Fan that had a Black, red, Blue wiring. Is this true or can i run any case fan to my MoBo/Cpu?

I'm fairly certain wire color does not matter, it varies by manufacturer.

Also to answer your original question. 3 pin molex is powered direct from the power supply and runs full speed always(unless connected to fan controller or has switch attached). 3 pin is powered from small 3 pin connectors off the motherboard and can be controlled via BIOS or software utilities generally.

Edit: added more info

Hmmm mixed answers... thank you for the replies. Newegg shows 3 pin connection to the mother board on there picture but says its 3 pin Molex. Im confused.

It may take some time to get the fans i need.

So can i safely run a case fan off of my MoBo for my CPU without causing problems?

Ok 1 more questions for you xHassassin. Im pretty sure running 2 fans on my heat sink wont be a prob watt wise because im not running that much on my Mobo as it is, but i cant find what my Max watt is for my Mobo. Heres a layout of mine http://h10025.www1.hp.com/ewfrf/wc/d...s&lc=en&dlc=en. what do you think?

I plan on running 1 fan from my system fan 3 pin connection to heatsink and the other off of the cpu 3 pin connection.

Wait.. You're putting two fans on the same HSF?

That's not going to do anything except screw up the airflow and make it worse off.

let me explain. I recently changed my Pc case to a antec 900-2. The case comes with 4 fans in it already. I had to unplug my old 92mm case fan which ran to the system fan 3 pin connectors because there was no room. Now i get a sys fan error, so i thought buying a heatsink that allowed 2 fans would solve the problem. 1 fan pushes air through heatsink other pulls and goes right out my 120mm case fan.
