Can someone tell me the truth about this stuff? I ordered some AS5 and then while talking to some colleagues they told me to that AS5 really isn't that superior to the paste you get with a CPU (or in my case an Arctic Cooling ATI silencer). I still haven't gotten my AS5 so I am seriously considering using the paste I have now (its just silicon paste). Safe idea? or should I hold on and wait for my AS5?
