Started out at 80c, opened the side panel and dropped it down to 76c, then decided to get a house fan pointed at the cards - now around 70c.  Then my RAID 0 array failed because the hot air from the cards was blowing forwards in the case onto the HDD's.  Now I have a fan blowing over the remaining good HDD to keep it cool.  Mining has brought on a whole new level of cooling requirements since when I started overclocking in the late 90's.

GPU fans are likely to fail very fast if you keep it on 100%, the bearings will wear out in at most 2 years.

A mechanical engineer's perspective on this... it mostly depends on the bearing quality and number of cycles. If your steel is flawless, they will last a long long time no matter how fast you run them. Otherwise, if there's a flaw (in real life, there always is), it comes down to how big the flaw is and how many cycles you run. Tiny cracks will get bigger over time. I think it's a linear relationship with # of cycles.

Anyway, the fan should last twice as long at 50% speed as 100%, if the steel is high-quality.

The important equation is about halfway down

It would have been nice if you could have chosen 2 options. As it varies from rig to rig. or card to card.
