I'll put it in simple words so that you'll have an easier time understanding this.
You have 2 coolers. You compare them. To compare them fair, you make sure the conditions are equal. Hence same fan RPM / airflow / dB. You cannot test 1 cooler at 3000 RPM and another one at 1000 RPM. Got it? Don't compare apples against oranges.
I'll not comment on your assessment on SPCR PSU test. I guess you've made it all clear
Also, your understanding of enthusiast is so limited. Go ahead, use 5 Deltas @ 5000 RPM. You'll be getting slightly lower temps and nothing else. You'll also get a splitting headache with all that noise. Enjoy it.
And yes, I'll call 9700 crap again. Because it's just that. Overpriced, overhyped crap. Many reviews & comparisons show that. It gave you 5 degrees less on NB? Great, I'm happy for you. Does it make it a better CPU cooler? Not at all. Also, the fact that your NB temps went down could very well be attributed to much higher airflow or inconsistent testing conditions. Judging by your comments I'd say you can't be trusted with testing anything.
My advice to you - do some reading, get familiar with testing methodologies, try (just try) to understand that not everybody has to overclock like mad and chase each 100 MHz at the expense of noise, increased power consumptions and failure rates.
Really, you're a funny guy
