Hey buddy, I pretty much made the same 'mistake' on my 2500K+212 EVO. Temps were pretty normal honestly, 31c idle and never 55c+ load OC'd @4.0GHz. This was after applying TIM that came with the HSF. Although I have now cleansed and reapplyed AS5 with far better results. So I would say it's safe for the time being, but certainly not for durability/reliability. Change that TIM if you haven't done so already!
As for monitoring, CPU-Z (as mentioned) works great for overall CPU details and CoreTemp works great for overall CPU temps. It monitors temps of all four cores as well as each cores' load %. These two are all I need for my CPU monitoring. Gl and have fun with your CPU
