Mate Nobody is a pro everyone still learns new thing/tricks/tips so hush now
also its a modified standard intel LGA775 Fan with HS
I f you doubt me mate go try it just get a newer intel HS with the fan and between the top of the plastic casing athe the controller baord for the fan u'll see tiny resistors/diode's all you have to do is remove all but one of them and reinsall the HS
and go have a look at your fan speeds ok
next time try not to make comments on what others have experienced until you have completely Tested the advise someone has told you
you assumed mate (ASS U ME)
Have nice time matey
