I just purchased my first AMD CPU, a Athlon II x4 630. Pretty sweet so far! Anyway, one thing I'm a little concerned about, I'm using the stock heat sink/fan and it seemed WAY too easy to put on. The little plastic lever you push to lock down the HSF barely had any resistance when I pushed it down. Coming from Intel 775s where you have to jam down much harder to get those spring loaded plastic pins into the motherboard, it seems like the AMD HSF doesn't have tight contact with the CPU. Is this normal? I thought these CPUs were supposed to idle in the low to mid 30s, but my idle temps are in the low to mid 40s with ambient temp around 24. No overclocking either and I'm using the thermal paste that came with the stock HSF. I'm using HWMonitor to read the temps by the way and I'm running a Biostar A760GM2+ mobo.
