PS3 Slim Temps good or bad?

i recently opened my ps3 slim, applied new MX-4 thermal paste and cleaned it, the temps are:

GTA V for 1 hour: CPU:56c GPU:59c fan speed:51%

XMB: CPU:62c GPU:67 fan speed:31%

are these temps good for a slim model? is 51% fan speed too much for the fan? and are these XMB temps good compared to the fan speed
