Almost bought this card on MM, good thing I found out about this thread before. It's absolutely ridiculous that Powercolor or any manufacturer can release an unfinished product like this then expect users to spend so much time and effort to make it work "somewhere" near advertised.
Flashing bios is not a procedure everyone can do and follow, let alone the chance of bricking it and RMA is also void.
I would avoid Powercolor from now at all costs.
ok gang uve all moaned about this card and i found the solution, well for me anyway but im sure it can help

Hi guys,
Noticed last night the odd grinding-type noise at idle. Modded the fan profile in the bios to 5% initial speed, and this got rid of it - must just be an odd thing that only happens at certain rpm.

First post
Like most on here I was initially dissapointed with the fan solution on this card as the default fan profile is rubbish. However flashing the bios or any one of several software utilitys (I am using rivatuner) will fix that no problem.
My card runs really quite cool at idle and only needs the fan at about 8% for no increase in heat in long surfing sessions and at that speed is really very quiet indeed.
As for performance while gaming I was happy from day 1 as it performs very well and so far I have had zero issus.
