my CPU idle temp @ ~66C (~150F) is that OK?

[mr1c3man]

I have overlocked my Phenom 9750 from 2.4Ghz running at 2.66Ghz now.
I originally ran it at 2.8Ghz, and it was running sweet, but now that Summer's here...it was running tooo hot. so i downed it abit
So its at 2.66Ghz but problem is (i know its hot weather) but its idling at 64-66C.
Is this ok? or should i set it back to standard clock speed of 2.4Ghz?
In terms of performance, it runs fairly fine because i usually encode simultaneously 2 videos with ConvertX2DVD...dont ask me what the temps are then because i dare not look.

So my Q is, is this ok? or is my Phenom due to be doomed?
