Hi All,

My Thermalright Silver Arrow arrived today and I was able to install it on the AMD processor ( with difficulty frown.gif ), but not sure how tight the screw should be. There is still gap between the board and the heat sink holder.

Should i tighten them until X shape heat sink holder touches the motherboard or half way thru is enough. I do not understand that we need to apply 70lbs of pressure, not sure how to gauge this.

Please need ur advice.
