Whoa now. I think you misread PcPer's chart. With the Delta fan it shows the the Ultra-120 giving the best numbers ("Delta T" is 4.5 degrees - best of the group) and with a relatively quiet Panaflo L1A it ties the Big Typhoon using a high speed, noisier fan at 5.7 degrees Delta T.
If you go strictly by that chart the Ultra-120 does 5.7 degrees deltaT at a lower volume and fan speed than the big typhoon. Delta-T seems to be the measure to temperature lowering based on that chart and the true measure of performance.
I had already read that review. It seems to show the Ultra-120 besting the big typhoon even with a relatively quiet fan.
Only the external thermocouple shows the Ultra-120 winning. The internal diode (CPU C) reports the same temperature for the Big Typhoon VX High Speed and the Ultra-120 + Delta SHE fan. Both the VX High Speed and Ultra-120 + Delta SHE resulted in internal diode temps of 34C. In my book, the internal diode temp is far more relevant to the performance of the cooler than the IHS temp reported by the thermocouple. It is likely that the thermocouple is responding to the ridiculous amount of air being moved by the Delta SHE fan more than anything else. I am also under the impression that the Delta T applied only to the thermocouple, not the internal diode, though it's not entirely clear whether Delta T applies to the thermocouple or the internal diode (or both).
Even if Delta T does apply to the internal diode temp, you are miscalculating the total load temp for the Ultra-120 with the Panaflow fan . . .
Ultra-120 + Pana L1A: Internal diode temp 35C, Delta T 5.7C, load temp = 40.7C
Big Typhon VX High Speed: Interal diode temp 34C, Delta T 5.7C, load temp = 39.7C
Of course, if Delta T applies to the internal diode temps, that means the Ultra-120 actually manages a temperature 1.7C cooler than the VX at High Speed, but it needs a monstrous fan to accomplish that feat. With a 102 cfm Sanyo Denki fan or Silverstone FM-121, I'm pretty sure the Big Typhoon would match or beat the Ultra 120 + Delta SHE.

If you look at the case, airflow in it is terribly restricted. I've seen the CNPS9700 beat the Big Typhoon VX like a red-headed stepchild in cases like that. All they've got is a 56 cfm exhaust fan . . . that's it. The fact that they even put an Amanda in a setup like that is ridiculous. Furthermore, look at the other coolers in the review. The Tuniq Tower 120 isn't there, the Scythe Infinity isn't there, the Big Typhoon/Big Typhoon VX isn't there, the Ultra-120 isn't there, the Noctua NH-U12F isn't there, etc etc.

That doesn't surprise me. It looks a lot like a hybrid between the Big Typhoon and an SI-128 or something, and the Big Typhoon has already been shown to be superior to the Tuniq Tower 120 with 100+ cfm fans (such as the 102 cfm Sanyo Denki fan). Most Tuniq users have complained that they don't get better performance out of the HSF using faster fans. What's nice about the Tuniq Tower 120 is that it provides good performance without having to swap out fans.
The FrostyTech review doesn't really show it in a positive light though . . . outside of the Ultra-120 and Noctua NH-U12F, the competition isn't terribly stiff.
