Hi guys,
I've seen OLD 486's with a heatsink and fan and the fan is still 100%. Ball bearing or not, there's something to be said for 'quality construction' of components.
I've seen it when it comes to engines especially. Small engines (mowers etc) have gone downhill IMO as far as build goes. Today it's all plastic, plastic and plastic. Save a buck and replace alloy with plastic.
Fans, engines, things in general ain't built as well as they were. That's why I like and ride old motorcycles. My 1974 Honda isn't nearly as powerful or as fast as todays bikes.......but it's BOMB proof.......that's the difference.
Over engineering is dead. Personally I hate this trend but what can you do? The market governs the price.......so make it as cheap as possible

.
I could go on and on.......
CHEAP SUCKS!!!
Yours
