Both of those coolers are beaten by current and cheaper coolers. The only people buying them are people not even taking a second to do any research on current coolers. I never said older coolers did not do a good job, but they have been equaled or beaten for some time and for alot less money.
Not so according to the graph in the reivew, it's at the top spot even. Yes there are coolers that beat it, but off the top of my head those would be the Thermalright 120 Extreme and Thermalright IFX-140, both of which cost more than $45.
PS: Why does it even matter that the QX9650 is cooler than anything P4?
Besides that I still find it amazing four cores run cooler than a single-core 65nm chip? Because it serves to point out that if the P4 is indeed hotter, then it is a better testbed chip for cooler testing. At least it was while LGA775 was still around, not sure how much longer some sites are going to be able to keep their P4 cooler test platforms going. I guess LGA775 adapters will be included by default for a long time though...
