Oh, you're a troll. The reviews at Tom's I've seen are consistent with what is elsewhere, often before others have done the corresponding test, so somehow they get the same result without knowing what anyone else will do. Carelessness I guess.

Alpha PEP66T (3800rpm Sanyo Denki fan) came in nineth (temp 39), Thermaltake Aircooler 22 (temp 43). Thermaltake Super Orb (6400RPM fan) at seven (temp 39) scores the same as Alpha PEP66T. Seems reasonable to me. Why not to you?
I quote from Lord Kyro's review at Tom's:
"We can only warn against purchasing the Super Orb, which is nothing but your classic phoney." Trying to suck up to Thermaltake by giving then a great review, I guess.
So somehow, you say due to carelessness or the Thermaltake ads (not) on the web page, the Super Orb tied with an Alpha PEP66T. But the excellent Alphas sit where they should compared to the others, judged by reviews elsewhere and the other excellent designs that score about the same elsewhere. (Of course if you put killer loud fans on Alphas they can kick butt.)
The Orbs often test well, but sometimes they do not. I presume you need to get a good one, where the center and outer piece are joined well, and the clip makes the sink sit just right on the slug, which is difficult to do because the clip does not press on the sink at a single point above the CPU slug, like usual clips do, but grabs onto a rim that is much larger than the slug. It was not so critical when the slugs were bigger.

Maybe this well respected person did not do a good design.
The only thing I could find was:

... even in a dual configuration the Gamma 28s installed in the UH X2 only put out about 18cfm as compared to the 27cfm of the 60mm YS Tech fan that comes standard on the FDP-32.

Maybe this (old article)is where the idea for the Silverado came from. The blowers are probably delivering more real-life CFM, probably a lot more due to the higher pressure and the well directed air flow. Fans (or blowers) don't produce anywhere near the rated CFM when attached to heat sinks (or under any load), due to the HSF's miserable air flow design, which seems to splash air at random and hope for the best. The manufacturer's test conditions are completely different, and no doubt differ from manufacture to manufacturer. Similarly the sound tests. Fans mounted to something make way more noise than by themselves unless the mounting is done with sophistication. Likewise the air flow itself will generate a lot of noise depending on how it flows, which translates into the HSF design.
Furnaces usually use blowers, most likely for their quietness, and also move large volumes of air. OTOH, a tiny one inch blower drum is bound to make a lot of grating, high-pitched noise when you spin it real fast to get high CFM.
