I've got more power supplies than I care to have.
More literally come
through the door every week. I'd rather just let them die and replace the
whole supply once in a great while and then recycle the dead unit rather
JUst hope that the supply doesn't do damage to any other part of the
machine (or indeed catch fire and do damage to anything else), and that
the rest of the machine doesn't run too hot (the PSU fan cools other
components too in most PCs).
than go through the nonsense of replacing the fan.
If you once replaced the fan with a decent one, it would carry on working
for 5 years or more.
