Your servers probably aren't running at 95C under load and have all components ventilated.

I dont think you shipped a whole Rack back because a single fan was broken either.

Fans are a FRU. The complaint was about sub-fru items.

There are no sub-fru items in Apple ecosystem, in fact there are no frus either.

I picked a component off the top of my head. Water damage is almost always the culprit in these repairs, which doesn't affect most servers (except for these [0] maybe?) Louis Rossman's channel on Youtube [1] can give you better information than I can.

I’ve had capacitors repaired.

Haha, of course you did - It's always a capacitor![1]

These mature cheap reliable mass-produced electrolytic capacitors of which we rarely see fault today, sure had quite the rebellious stage[2] [3].

Interesting, from the announcement on badcaps.net[3]:

"Back in April 2002, I had an idea to start a business (actually spinoff of another business) servicing motherboards at component level amid the mass capacitor failures plaguing the PC industry."..."The store boomed from its launch all the way up until about a year ago. Over the last 6 months or so, I have sold very few capacitors. Once my stock depletes, I will be shutting down the Badcaps.net store."

That wasn't an accident, but some company trying to cut corners on what was a well-understood manufacturing process.

You probably don’t bring your server to hazardous environments where it can get drinks spilled on it.

For laptops this kind of environment is common; in fact most of Louis Rossmann’s repairs are about liquid damage.
