Once you're talking overclocked quad-core, the difference between 3 heatpipes and 6 heatpipes is the difference between heaven and earth. Find me a review which says different.
I love a challenge....
Here goes...

and here's one with the staunch 3 heatpipe Red Scorpion going up against the mighty TRUE (Q6600 @ 3.3GHz)

As a passing note. The TRUE is a good heatsink, unfortunately the performance is not out of the box in many cases. Bases on many Thermalright heatsinks are as flat as Kim Kardashian's rear end. To get the best out of them (not Kim's rear end...maybe) they need lapping- time consuming and not a job to be undertaken lightly for an average computer user. Most TRUE owners I know lap the base in any case as it comes Nickel plated, which has a quarter of the thermal conductivity of Copper at the 30-70C temp range (Copper 398 W/mK versus Nickel 90W/mK).
Number of heatpipes on it's own means squat. Heatpipe cores come in three main varieties;
Sintered Copper Power - the best
Groove - middling
Multilayered Metal Mesh - Wal-Mart special.
3 Sintered Heatpipes beats 6 mesh heatpipes (but not a straight flush at Vegas)
It's also best to take into account fin surface area, fan number and actual (as opposed to stated) airflow, whether the cooler is optimized for CPU cooling only or vents airflow over the MCH/Chipset, mosfets and RAM, and for those who swap out componentry regularly, ease of install/uninstall- including coolers that use adhesives to secure backplates.
@CMH
The moment you typed
"I agree that I might be a thermalright fanboi" your argument became invalid.
I presume you can also provide reviews, and not just your anecdotal personal thought, on these supposed "rubbish" coolers? Without providing some degree of empirical proof of your assertions it just seems you are unfairly maligning a range of products.
Also, please don't let our little contretemps dissuade you from answering my plea should I have recourse to ask for assistance in the forums. If I were in desperate need of advice on say, what colour novelty flash drive should I purchase I should expect you to weigh in with the full force of your knowledge.
Cheers and happy Googling.
