Lubrication and GPU fans

I have noticed a trend with GPUs. The first part to die on a GPU is usually the fan. This seems curious - historically, power supplies were the most common part (from my experiences) to die, and often it was also because of the fans that were included.

For most modern GPU fans, what kind of fans are being used? I think that the majority are sleeve bearing fans - even the good ones like MSI's TwinFrozr.

I was able to find this on OCN:
http://www.overclock.net/t/1336160/how-to-repair-msi-twin-frozr-heatsink-fans-or-how-to-fix-fans-where-there-is-no-hole-behind-the-sticker/0_100

There's a bunch of other similar guides scattered about the web.

That demands the question, do these fans need to be oiled? Should we run the risk (especially with warranty stickers being the way they are nowadays)? This is especially interesting because GPU fans are mounted of course, horizontally and near the largest heat source in the PC - the GPU itself. Considering these are sleeve bearing fans ... that undoubtedly has a negative effect on the reliability.

Yep, fan cleaning and maintenace is a must if your able to manage to do it.

But always do consider your warranty above everything else.

Bearing lubrication failure will cause fan failure, fan failure you know leads to system failure.

To reduce friction and minimize overheating it needs re-lubrication, lubricants on all fans of these types evaporates through time.

Ball bearing - thicker lubricants
Sleeved bearing - needs refilling and resealling (like sticker or tape)

Sleeve bearing fan systems evaporate faster.

Warranty or rejuvenation your call as always . . . MECH WARRIOR!!!

I agree but don't use to much you will just end up flinging lubricants all over the inside of your case.
