tried to do that now:
I'm not sure how long will it lasts like that without raising the temp too high
Anywho, I can still hear it, no significant improve, not as loud but its noticable enough
The case fans for instance, are dead silent, even at 100% I can't hear them, and I have 3 of them
edit: oh ok just checked, case fans can only reach up to 760rpm at 100%, so maybe they are not comparablle as such..
edit2: on the left window, currently it says: CPU=913rpm (20%) and CASE=1060rpm(100%), not sure if its correct but it seems that they are spinning at about equal speed, yet only the cpu I can hear
bottom line:
this cpu cooler is crap, I need a new one, no doubt
