Are these temperatures safe?

Hi I've been overclocking my 4670k this afternoon, I've managed to hit 4300MHz with a vcore at 1.20v.

Under stress testing I've hit a peak of 75 degrees. Sits at about 38 idle (ambient temperature hot, maybe 28), I was wondering if this is safe for my cpu, and I can push it further, or whether I should drop the voltage and be happy with a more rubbish overclock.
