I just installed a new heatsink/fan and when I look in core temp cores 0 and 1 are 7 degrees higher than 2 and 3. What could be the cause of this? Improper thermal paste placement? I used arctic silver and applied just like they directed. The heatsink I'm using is a scythe ninja plus. Edit: under a full load it's 2/3 degrees between 0&1 and 2&3 Edit: So like 30 mins in running with a full load 4 instances of Prime95 and RTHDRIBL Maximized core 0 and 1 are at 61 degrees and 2 and 3 are at 59 degrees. Is this running hot, I haven't over clocked anything yet. Or is it because it's a new system and hasn't been broken in yet.
