12v off a Power supply??

__________________i mean, the PSU supplies 12v of power through the molex connectors, doesn't it?

Yes - 12V is the yellow wire.

Yep. The yellow cables of the Molex connectors are the 12V power cables.
Other colors indicate other voltages, while black is ground. You can safely connect the fan to the molex cables. (Note: some, esp. Antec, have 'fan-only' molex connectors.) However, if you continue having stability issues with your rig, I would take a look at that PSU you have... 'Mega Power' does not strike me as a well known brand name for PSUs (not even close...). Can you check how many amperes the 12V rail(s) deliver? This should be printed on the label of the PSU..

WOW - thanks for the quick response, from all of you...
__________________so, the fans i am getting are 120mm 12v fans with a 97cfm, what are your thoughts on this? oh, the fans come with two wires, a red and a black wire, i would connect the black to the black of the molex, and the red to the yellow of the molex, correct?

It sounds like you are using bare-lead fans?

He means fans with bare wires (thus no molex or other connectors, but just the wires with the naked copper).
How much you paying for these fans, and which ones are they? You might want to look at alternatives... like these Silverstones: http://www.newegg.com/Product/Produc...82E16811999344 110FCM at full blast for $15 a piece. Plus, has molex connectors, and 3 pin connectors (could be connected to a mobo, but DON'T do it with such high-powered fan... Molex is much preferred)

yeah, the fans are coming with no connectors, in other words, bare-lead fans... i am paying R100 (bout $13) for them... i can't seem to find decent power fans in SA, so i have to resort to getting them from radio shops...
