Re: Can IC`s which run hot last longer if heatsinks are glued onto IC`s when new ?

ata33 Seagate hdd already works noticeably faster, after I glue a
hsink onto its hottest IC. In 12-03 I glued a hsink onto a nVidia
nForce 2 south bridge ( hot ), its IDE controller then worked 5-8
% faster.

Neither a hard drive nor a synchronous clocked bridge chip will run
any faster if you cool one chip. I just ain't happening.

Can hot IC`s last longer, from this added cooling ( i.e. hsinks are
fitted ) when IC`s are still new ?

IC failure rates double for about every 10 deg C increase in junction
temperature, so heatsinking a chip can reduce its failure rate. But
hard drives usually fail for mechanical reasons, and most chips are
designed to last a long time as-sold. The people who design hard
drives understand all this stuff.
