EDIT: I don't trust a review with so many high fin density rads, i.e. high fan speed rads, that doesn't test anything beyond 1250rpm.... That's kinda pathetic tbh, and gives only a very incomplete picture of the different performance profiles of the rads; Martin's (and Skinee's) testing methodology is FAR superior, as they ran the fans up to 3,000rpm which allows you to see how well a given radiator scales, what it's "sweet spot" between noise/performance is, and weed-out radiators that lack upper end "oomph" if that is what you want. These reviews offer NONE of that.
I will away SkinneeLabs or BundyMania reviews, as I don't trust any other site/reviewer to be completely impartial nor to have an absolutely impeccable and perfectly repeatable testing methodology.
(Kinda sad that there are only THREE PEOPLE who do a good job testing and comparing radiators... isn't it? And because of reasons that I don't know, it's down to two as far as I know. If the manufacturers were willing to send me rads/etc, I would be more than willing to do my absolute best to continue testing equipment in the shadow of THE Legend himself, Martin, so maybe I'll look into that. Until then, thank you Bundy for your awesome reviews)Edited by nleksan - 9/13/12 at 3:59pm
