I am sorry, I would be more careful and clear from now on. I tried to respond to psot 7 in post 15.
The sound definitely is coming from the cpu fan because of it's spinning, nut it's not the usual hiss or hum. It's high pitched, low volume sound. (The sound is beep like not from pc speaker, probably can be compared with the sound from water motor from a neightbour's house
, low decibel though)
My complete Config
Core i7 920
Gigabyte X58 UD3R(got msi eclipse exchanged with this)
patriot 6gb 1600
palit nvidia 9600gt 512

corsair tx750w
1tb seagate 7200.11
pushpins are inserted properly, checked it.
This is the first time I'm going for higher end system
. Previously was using amd 4850e(which had a quiet fan) in antec sonata 2 which is a great silent cabby+psu. It was so silent that, it's difficult to say whether it's on from a 2m distance without looking at ledseven at midnight.
I was planning to overclock this a bit, so planning to get n aftermarket cpu cooler. Hope that would solve my problem.
One of my friends suggested that in general intel cpu fans do make more noise than amd's. It it true? If the sound I get is normal, I am not bothered, I can live with it. But if that's not the case, I would like to fix it.
Thanks all.
