I would like to emphasize these statements from an MSI rep. as utter nonsense, shame on them.
The details...
Basically our cards are designed mainly for one thing.. gaming (the clue's in the name). They are not intended for use under "industrial" load conditions where they would be needed to run flat-out continuously day after day, week after week with potential high heat levels.
^ What about all the people that have been Folding and doing SETI calculations for many, many years? Lets not mention them.
MSI HQ have been working on the fix since late December to make some changes to our Twin Frozr coolers to stop this from happening. At the centre of the fan there is a 3mm gap inside where a specially made gel is inserted to keep our fans running smoothly and quietly to give you the award-winning silent conditions during idle and gaming modes you have seen and/or heard about. MSI has since reduced this to 2mm. This doesn't sound much but has in fact solved one of the issues whereby there was extra space for air to squeeze inside the area alongside the gel to cause tiny air bubbles that
(while at 100% fan load for a long period of time) forces the gel to leak out onto the fan shroud and surrounding area.
The final issue that was fixed was simply not to put as much gel inside the fans core.
We intentionally put more gel into this area during production to ensure your cards would continue to run smoothly and that durability would never decrease. Sadly our good intentions came back to hurt us since many customers are using R9 Graphics Cards (and R7) to mine for coins jumping quickly onto the Cryptocurrency bandwagon. Our cards we're not designed for this.
Under normal gaming conditions this would not happen (rare cases it may). MSI HQ wanted (yet again) to improve our award-winning Twin Frozr coolers further by solving any and all reliability questions of the running of our fans... hence more gel.
People that knew about bitcoin 4 years ago have been mining way before the mainstream miners that jumped on the cryptocurrency bandwagon after the surge of BTC price went to over 1,000 USD last Nov- Dec of 2013.

Unlike our competitors, our bearing is made from a special ring made from a mixture of pressed cooper shavings and oil –
This unique design avoids the need of ball bearings so the fan can run quieter.
Ball bearing fans produce slightly more decibels but are way more reliable, and the reason they use cheap sleeve bearing fans is the cost, as they do not want to use more reliable fans, meaning more money for the shareholders. In actuality their choice is hurting them more than it is benefiting them from using cheap quality sleeve bearing fans.
Those customers with Graphics Cards pre-January that are worrying about oil leaking in the future causing harm to the fans.. don't worry.
The oil leaking is from the fans hub and not from the bearing, thus will not impact the lifetime running of the fans.
BS once the fan lube leaks the fan will eventually fail to operate and is a design flaw.
I'm done and sorry for the rants but it urks me when Reps of Big Corporations take advantage of customers by trying to hide their tracks by lying to customers for the poor choices made by said corporation and forgetting the customer is King as they pay their pay checks and salary's.
Good luck and happy times,
