i think freaky had the same problem as well and got his board replaced at rashi
@ thodoroukus .. hmm i read about that on i think overclock.net… anyways .. i got the fan replaced by i think the same size fan.. so i think i`ll get the same problem again.. though its been 2 months and no problems with the new fan as of now.. though i have seen this new one can reach as high as 11k rpm and stay there for quite some time. but its not as noisy as the old one..
hopefully i shouldnt get any probs now .. 
..
btw. what`s RMA? how do i do it? 
…
Thats why i bougth a Fanless Mobo
