Thanks, Martin! I'm always looking forward to your test results!

Anyway:
The more numbers we get on the monsta/treibwerk, the less impressive they look, imo. Sure the monsta beats the PA, but a 420 vs 360 rad isn't exactly a fair fight. Even with the built in shroud the $35 (?) triebwerk fans could only perform about as well $5 YL. I really like the idea of 140.x rads, but I think the monsta handles this poorly as far as price/performance/size goes. I also like the idea of fans optimized for radiators, but the numbers speak for themselves as far as triebwerk goes.
