Those load temps are a little on the high side, so are the idle, but it's not really a problem. However, as long as you aren't running prime95 all the time and keep your temps under 70C, you will be ok, but personally, I'd try for 4-5C cooler.
It is not recommended that you use turbo mode when overclocking. You still get to have speedstep, which underclocks your system when not under load, and since you are overclocking already, you get control of the peak load. Your system should be more stable as well, it may even become cooler at load.
