Annoying fan noises in mini itx HTPC
Hello !!
I bought this really nice and small Mini-Itx case :

And bought an intel mini itx G41 based board for this case.
Now...The case's fan are quite quiet, But although I can put an regular 775 cpu fan, It seems to be quite noisey. All intel boards I used so far (g31 based mostly) have this thing that spin the cpu fan to high RPM, And I could'nt find a workaround this (Bios update, Bios setting doesn't change it).
I used Intel 2180 cpu with this babe.
What I did is replaced rear fan with quite quiet glacialtech 80mm fan (This is maximum fan size for rear of the case),And connected it's 3 pins to the case fan connector which spins the cpu at a lower RPM rate than the CPU fan connector, And built a cartoon tunnel than drive out air out of the case.
Temp looks fine when not under load (Around 40 deg cel.), But it goes to about 55 when playing HD movie.....
I tried to made the glacial work with 5 Volts, Although it's quiet, It doesn't cool well (Around 46 deg. cel when not under load).
I don't know right now how to improve cooling/noise ratio.
I think of getting some silent cpu cooler and making the glacial tech rear case fan to work at 5 volts again....Any suggestions ?
