Intel Stock Pentium D Radial Curved non-Bifurcated Fin Heatsink Review
Intel Stock Pentium D Radial Curved non-Bifurcated Fin Heatsink Review
Abstract: Intel's own Radial Curved non-Bifurcated Fin Heatsink (RCBFH) reference solution is a fairly well designed cooler.

360° View - Intel Stock Pentium D Heatsink
Information on Frostytech's test methodology is available here.
The Heatsink Fan:
The stock Intel Pentium D heatsink is built with an 84mm diameter fan that spins at speeds an est. 800-2600RPM. The speed of the seven-bladed Pulse Width Modulation (PWM) Nidec fan is controlled via the BIOS. Power is supplied by the 4-pin PWM fan cable which connects to a standard 3-pin or 4-pin motherboard fan header. As with most Intel reference LGA775 heatsinks, the fan is suspended 2mm above the cooling fins, without a complete fan guard. The plastic motor supports offer some marginal protection from errant wires being drawn into the impeller, but it's best to ensure cables are kept tidy inside the PC.

Heatsink Top:
With the fan support structure removed, the unique design of Intel's stock Pentium D heatsink is clearly visible. The central copper core is 13mm thick at the base, then the remaining 22mm deep cavity opens up so there is just 3mm of copper along either edge. The aluminum 'donut' measures 87mm in diameter, though each side is comprised of 2mm of aluminum and ~21mm of aluminum cooling fin. Each aluminum cooling fin is 0.6mm thick and spaced 0.8mm at the base, 1.7mm at the tip.

Heatsink Side A:
The body of the stock Intel Pentium D heatsink stands exactly 30mm tall, with an overall height of 72mm. The plastic clips lock directly into the 4mm motherboard mounting holes which surround the LGA775 processor socket. To release the heatsink from the board, the upper portion of the clip is rotated 90 degrees and pulled upwards. The heatsink then pulls free of the board.

Heatsink Side B:
The fan support frame locks onto the aluminum portion of the heatsink with a couple slashes cut into the side of the fins. The fan frame is held in tension, so vibration and rattling shouldn't be an issue. Air is exhausted outwards from the cooling fins, where it can then be used to cool adjacent board-mounted components.

Heatsink Base:
The copper base of the stock Intel Pentium D heatsink is 35mm in diameter where it makes contact with the processors' integrated heatspreader (IHS). The heatsink ships with a thin grey pad of ShinEtsu thermal interface material pre-applied. The copper is machined perfectly flat, and is smooth. Surface roughness is on the order of ~8 microinches, which is considered excellent. Owing to the pinless design of the LGA775 processor and socket, the mounting clips and hardware on the heatsink are actually rigid mounts. It's the CPU in the socket which provides the tension to the equation, by means of its many springy electrical contacts.
