I'm seeing a lot of fan failures on my cards. I've had to RMA two cards that both had fan failures and stopped hashing correctly. It's taken two months to finally get one advanced RMA, and I had to send the other card BACK to the factory again because it was returned to me with the same bad fans I sent it in for, plus it won't hash without crashing.
I have (15) Asus R9 280x's, and today I've discovered that FOUR more fans have failed on 4 other cards. That makes for a total 9 fan failures out of the 30 fans on my Asus cards. The failures aren't limited to a specific rig, or a particular fan. 3 of my rigs were built with Asus cards, and have seen failures in cards in each rig.
They either spin slow, or are so stiff they don't spin at all. There is so little spare lubrication in the fan bearings they are dying left and right. I've been trying to find replacements from anywhere I can get them, but the size isn't common (93mm?), and the Asus store doesn't carry them or won't sell them to me.
OTOH, I have 5 cards from another manufacturer that have been running without issue, and no fan failures. The sample size is smaller, but I saw my first fan failure on an Asus card within two weeks of using them. If there are any Asus reps that follow these forums, I could really use some assistance. With the headaches of just dealing with two RMAs, I really don't want to send these cards back unless they stop hashing. I've put about $9K into Asus cards, and with the warranty service being what it is, I'm seriously regretting my choice.
