Really? 40C? Yow!
It's surprising to me that they bother to specify 6 l/min. I had the impression (from Bill Adams'
Radiator Heat Dissipation Testing) that, above a certain fairly-small minimum, coolant flow didn't matter that much - particularly for the flat-tube radiators.
40C... so in a 68F room, the coolant would be 60C/140F? Of course, to the extent that you
weren't trying to dissipate at their rated number, that temp should fall.
OK guys - you're totally right. There might be numbers, but they're not
all the numbers and so qualify as "marketing-speak". Maybe they planned to remove these partial specs from all the web pages and the one I ran across was an oversight...
IMHO, folks choose these radiators (and the thermochill 120x1) because they
fit. I don't think a "real" set of performance curves would hurt sales at all - and would help with things like fan selection.
I've a couple of PCs "out there" with BIPs in 'em (coupled with Eheim 1046, Panaflo L1A at 5V, Swiftech "old style" center inlet blocks). For silencing a system, these work great (one of the above systems is in a recording studio - not on the same side of the glass as the mikes, but noise is still an issue).

software guy who got into this because noise really bugs me...
