Hi Guys,

I am considering buying 3x ATI Sapphire 5850 Extreme 1024MB graphics cards for bitcoin mining, however as these cards do not have a blower style fan, will the temperatures struggle a lot when three of them are sandwiched together in crossfire? Due to the design of my motherboard, there will be no "breathing" space between the cards.  A picture of the card is below:



I have been looking for some "reference" style cards but all the stores I have tried so far have been out of stock unfortunately. So that is why I am looking at these cards, hoping that they will be able to bare the temperatures and so suffice for my requirements.

If any of you have had experience with these cards, please do feel free to reply to this thread with your experiences and opinions.

Kind Regards,

Alec

ATI Cards are around 3-4 times faster than NVidia cards at the moment... I have dual GTX260s at the mo and they get 50MHash/s each, whereas a sinlge 5850 can get 300MHash/s or so! I am going to be upgrading to a triple 5850 system soon.

50MHash/s per card, so 100MHash/s total. I am using 2x NVidia GTX 260s.

I am looking to upgrade to triple 5850s very soon though!

Thanks for posting this. I use Windows 7 myself so am substantially more at risk than say, a Linux user.

Yeah it does seem kind of strict, but I can definitely see the reasoning behind it. So the slight inconvenience is well worth it in the long run in my opinion.

Hello, I have been doing bitcoin for around 1 week now and thought I should make an account here to say hi!
