My FX5700 has dual fan heatsink, albiet both fans are quite small (about 1 inch). One of them has been extremely noisy for a year or so, but seemed to function ok. Apparently, it has now met its maker and stopped working altogether. The other fan is still running ok, but the metal of the heatsink is quite hot to the touch. Question is... how long do you think it'll last before the card bites the dust once and for all? Also, what other bad sorta things do i have to look forward to when it does crap out as far as the rest of my system is concerned? And no, a new card is not an option quite yet... gotta pay off my new phone first.
