re cpu fans in article apr mfltd co uk nmp mfltd co uk writes just got a mhz dx system and am considering getting a fan for the cpu the processor when running is too hot to touch so i think this is a fairly good idea long ago when i did some electronics training i read somewhere that the regions within a chip that define junctions gates etc slowly diffuse over time and this increases with temperature hence a hot chip goes off spec sooner has anyone out there got a cpu fan yes is there more than type yes seen glue on tape on clip on one inch square and larger my favorite is the inch plastic u s toyo fan i use just plopped down on top of the chip during open case service do you have to remove the cpu from its scoket to install the fan depends on the mounting do all cpu fans derive their power from spare drive power lines only if the manufacturer was smart anyone had any trouble with cpu fans only if it goes out got that blanket effect which doesn t help chip life does anyone have any evidence that cpu fans are a complete waste of money longer system life makes good economic sense to me how are these fans attached glue clips melted cheese yes well not the melted cheese roughly how much cooler will the cpu be with a fan as opposed to without lets you touch the surface the rule of thumb for cooling solid state an advert i ve read claims f vs f any info appreciated the attached fans look slick and work well but i m bothered by the potential loss of cooling if the fan goes out at least with the power supply fan you can reach back there every few days and feel the fan blowing i prefer to put a stock fan off the drive brackets or front panel to blow air across the cpu depends a lot on case and board layout though on chip fans from fry s electronics in the sf bay area are about i get the stock power supply fans for about steve
