It worked perfectly when I bought it 3 months ago, now the fans and blue LEDs on the bottom stopped working. I've updated drivers, tried manuallly setting fan speeds, nothing works, still gets over 90 C during gameplay, then slowed performance, artifacts and crash. I tried running the fan health check in Trixx, but they both fail. I opened a ticket with Sapphire, they sent me to Althon Micro, who offered to warrranty the quick change fan assemblies, but I'm doubting that will fix the problem. Any ideas what else I can do to troubleshoot? Either I've tried everything possible, or they are not understanding the problem. Also, they want me to pay them a $20 deposit on Paypal before they will send the fans, then I would return the old ones and request a deposit refund. Is that normal?
