OK im new to this and it is my 1st build. I have everything here for my build but my as5 hasn't come in mail yet. Not sure when it will be delivered cuz I just moved and forward mail is taking forever. MY question is can I go ahead and build system with stock HS/fan and then later remove the hs and apply the as5? Will I need to take cpu off motherboard (Ithink this wil be best to cleann off amd thermal compund) and when I put back in the cpu will I have any problems with having to reload Windows? I hope since it is same cpu, it will not require reloading windows.
