Kindly note i have replaced the original 80 mm fan with a 92 mm panaflo fan. (I had bought it from a TE member with the fan blade assembly spindle broken, hence modded it with much higher CFM panaflo.)
Price: Rs.2000/- + Shipping.
Cons: No rpm sensing
Incase you want to use ur existing p4 fan (yes it fits pretty easily and nicely + plus you get rpm sensing )
then the price reduced to Rs. 1750/- without the panaflo fan.
cons: cooling efficiency slightly reduced as compared to the 92mm panaflo fan.
