FWIW, I, too, have heard that the rule of thumb is to try to keep the CPU's routine temperature below 50C for maximum life. But, we had an Athlon PC at work that routinely ran at 50-52C for several years (until replaced by an upgrade). In the BIOS of my home PC (specs below), the lowest possible warning temp is 50C and the lowest shutdown is 60C. It tends to idle in the high 30s/low 40s, but sometimes when doing heavy-duty 3D stuff for extended periods, it'd sometimes trigger the 50C warning alarm, so I've raised it to 53.
These are pretty conservative figures. One web resource puts the maximum temperatures at somewhere around 65C to 90C depending on the CPU: http://www.heatsink-guide.com/maxtemp.shtml . Your CPU is similar to mine, Regular K, with a max temp of 85C, so 50-60C should pose no trouble.
