I was refering specifically to after market d00d
made it clearer
Well, I would assume competition with the OEM Dual slot varieties that iirc have been designed by some of these aftermarket companies maybe could've led to legal issues? I've noticed this also, I've still got my AC Silencer 5 rv2 on my old X850XT PE AGP lol! Great cooler for how small it truly is! I wish more companies would use that fan design, it moved a lot of air with quieter results, sure it can't peak as hi as modern dual slot w/rear vent, but it never sounded like two hairdryer's modified for 10,000 volt systems either!
I also think the top-down style of the AC S1's, coolers like on my Palit 9600GT Sonic, allow more cooling surface area for heatpipes, more fins to be directly cooled initially, sure it may recycle air, but as said earlier, that's why leaving a couple expansion slot covers open helps greatly. And more modern desings be the AC X2 cooler that was on my 1950Pro, sure it worked, but all that heat right at the MB/Slot area? I hated it!
Really I think the OE Dual Slot rear exhuast coolers are pretty effective, but due to limitations like said in fan design and size/clearance constraints is why we're seeing coolers that recycle air in the case yet are somehow more effective, but I'm sure someone will release a new one that's maybe 2 slots by itself, that'll help get more efficiency by allowing larger fins, pipes, air vents and fans...it will be a bash fest for sure, but I bet it will be one helluva cooler too!
