with fans at the highest rpm my readings are: CPU : 29 C GPU: 40 c System: 23 c are these temperatures cool enough, say if i wanted to do some overclocking?
those temps are very good mine look like this (see below) and I am overclocking: CPU: ~34C GPU(idle): ~50C [the same applies when overclocked] GPU(load): ~68C [the same applies when overclocked] system: ~32C HDD: ~32C why would you want to overclock? that system looks pretty good as it is.
Idle or load, those are fine. You can overclock, but take it slow and make sure to test it out with dual instances of Prime 95 or just snag Orthos (made for multi-core chips). Sure, it's good, but, why not overclock? That's fun too.
