Interesting if not a coincidence, as i was looking for the 'default' ty-143 fans yesterday and could not find them in either of the two local retailers; both of which allowed you to order them btw, so no issues even when out of stock. No more, they're not even listed.
Would be seriously pissed if they stopped making them
As to the coolers themselves, can't say i see the point, but.. if it works for someone, why not.
Pride, honour and purity.
