anyway to stop the hdd noise changing?

[double t33]

i have a macbook pro 2011 13" 320gb hdd and only just started noticing it but its really annoying me now, whenever i rest my palm on the right hand side of the touchpad the hdd noise will stop then when i remove will start up again, not a really loud noise but an air blowing noise that sounds like its cutting off when i press on it lightly, i wouldn't mind if the noise was on constantly its just on/off on/off cutting in and our whenever i type when i rest my hand on it

will any covers stop this or is their a fault or something with my mac?

you can try opening it up and see if the hard drive is loose, if that is the case you can try tightening the screws around it, see if that helps. You can always get an SSD too

Yeah stated above open it up and see if its loose from the housing.
Mine makes no noise and its really quiet

It should make the same noise whether your palm is on it or not. Something is loose. Check the casing screws, then pop it open and check the hard drive bracket.
