FrostyTech posted a review on the Intel Stock Core 2 Duo Radial Curved Bifurcated Fin Heatsink
The Intel RCBFH design is engineered to be cheap to produce, easy to install, and thermally efficient. This is the stock Core 2 Duo heatsink, and it is generally speaking a well designed mass-produced cooler. The heatsink uses a suspended 4-pin PWM 84mm diameter Nidec F09A-12B1S2 fan, it conforms to ATX motherboard keep-out and high recommendations, and LGA775 weight restrictions.Intel Stock Core 2 Duo Radial Curved Bifurcated Fin Heatsink Review
