or this:
the fans in my antec 300 are vibrating the case a little bit and creating noise.
for instance if i put my hand on top of the case, it reduces a little bit of the whirring noise and sorts of smooths out the white noise a little. The same effect happens when i leave a book on top of it.
I'm keen to try and fix the fan noise by rolling out the rubbers onto all my fans. I was wondering which of these two methods pictured above quietens the fan more.
