Mines also a DCE model that's recently been sent to France for repair, subsequently turned out my 4000 mobo that was dead.
Anyway I thought while it was there I'd ask JJ to replace the fan and service the card, so now I'm really glad I did!
Recommend anyone with a DCE cyberstorm to change the crappy fan immediately!
We should point out this particular card is now a fully functional CS MKIII with no such worries :-)
