Hmmm fan looks fine. More like an 80mm though but ok.
Probably it is plugged in but the RPM monitoring on the fan itself is broken.
Yes those adapters exist, but you can also just cut the wires and do it yourself. It's what I do, those adapters are sometimes pretty hard to come by
oh and just a notice;

cant!! got it as a ift fom my cousin!! ... will try it in my friends cabby!!
but do such 3 pin to molex converstors exist??
They exist, and most local computer shops should have them. We retail them at $5 and probably sell 15 a week or so. They're very common.
Hey dhruvwali... Happy 2011...
Can you tell me what setting have you kept in bios for the fans??? in certain boards there are options to switch off the fan monitoring and temperature readings...
EDIT - My other suggestion... try connecting it to a DC source directly... you may have to cut the wires and connect it but its safe as long as you have removed the AC power... if the fan spins then something is wrong with the mobo...
HMM .. found out that my coolermaster 90 cfm led fan is also not being detected in bios...also it doesnt run at all with motherboard headers .. but with molex both the coolermaster + delta fan run perfectly albeit noisy .. (hence i wanted to run it via motherboard)
but my 2 other coolermaster fans which i got with my cm elite 430 are running fine via bios .... they both have only 2 wires in the 3 pin connectors ... is that the difference??
OK... this confirms that some fan control software (either in bios or in your mobos software) is controlling the fan speeds...
