Would you class this as a stable O/C?

Hi,

I have just fitted the EK Supreme HF 240 watercooling kit and clocked my i7 2600k to 5Ghz

I ran Intel Burn test on very high for 40 loops, and then prime blend for 8 hours, no problems.

Temps are 68,75,75,74

Do you think this is enough testing to class as stable?

1.45v in the BIOS but around 1.40 within Windows after vdroop

What's the hottest you would be comfortable with on an i7 2600k?

I am assuming it won't get as hot as IBT when encoding or gaming
