Are my temperatures OK for an overclocked i7-3930k?

[Niokiryth]

Hello, I have an i7-3930k overclocked to 4.5GHz at 1.44 Vcore on a GIGABYTE X79-UP4 in a Corsair Carbide 400R with the stock fans and a fan from a 212 evo as a bottom intake and most hard drive mounts removed. When running Intel XTU stress test I the temperature is average of 66 Celsius. The idle temps are around 37 celcius. I am using a Noctua NH-D15 with both fans with NT-H1 Thermal Paste.

Those are good temps. I wouldn't be worried. Tj max is at 91c, it will start to throttle at that temp. I'd say you've got plenty of headroom
