I've got hold of an Intel heatsink/fan from an E6600. Although visually similar to older mid-spec units one thing struck me immediately ... the fan runs 10% slower at 2,000 rpm idle speed. Intel say that the Conroe/Allendale unit must NOT be used on other Socket 775 CPU's - I can see this might be a good enough reason.
Other details:- copper core, siamesed fins, 500gm, 7 fan blades, rounded fan support posts, a truly bizzare 3-piece thermal pad, maker's name Fukikura, 0.60A (higher current than any other 775 HSF I've seen), product code D60188-001

One last post on this topic as I've found what I needed to know myself by buying a couple of boxed retail units.
As stated in the last post the genuine E6600 heatsink fan is rated at 0.60A. The genuine E6300 heatsink fan by is rated at 0.20A which is the lowest LGA775 power draw I've seen yet. (Put another way it's 7.2 watts vs 2.4 watts.)
Both fans spin at 2,000 rpm default - checked off-chip.
I've measured & weighed both the heatsinks and they are virtually indistiguishable although the E6300 has a turned copper base typical of all previous Intel heatsinks while the E6600 has a flatted copper base - something I've never seen before.
The E6300 fan has a larger diameter (approx 80mm vs 75mm) but the blades are flatter and thus have a narrower angle than the E6600, so must be quieter (at the same rpm's) but probably push less air. The E6300's blades also don't reach as far up the fan hub as the E6600. The taller, mose aggressively angled blades are probably why the power draw on the E6600 fan is 3 times that of the E6300 but I'm just guessing.
The part number on the E6300 is D60188-001 although this is probably irrelevant as Intel swap numbers at will.
Final thought - for used / non-retail boxed / OEM-supplied CPUs there are going to be a lot of people buying Allendale (E6300 etc) heatsink fan combo's that are not suited to the higher-spec Conroe (E6600 etc) processors. Just like there are today people unwittingly running Prescott CPU's with Celeron heatsink fans complaining about overheating when it's the mismatch that's really at fault, not the CPU. |

I bought a E6600 with stock fan yesterday. Though I get an average temperature of 55C which to me seems abit high.
I think the 3 thermal pads pre-attacthed to the heatsink fan must be no good, and would advise cleaning it off and applying some paste instead.! |

Weird ... are you certain that all four fasteners were pushed fully home?
I've tested an E6300 and the temperature never rose much above ambient using the stock Intel cooler.. |
