Overclocking: i5 2500k

[Tincel]

Hi, I would like to oc my i5-2500k (actually running with the base clock @3.3 GHz) 

My CPU-cooling is a gelid rev 2 tranquilo with a bequiet pure wings 2 fan (120mm) 

My mainboard is the Asrock z68 pro3 gen3 and my power supply is a Thermaltake berlin 630W with 80+ certification. I have 8gb of corsair vengeance LP @1600MHz (dual chanel 2x4gb).

The all system takes place in a Zalman Z11 and I think the airflow is correct. I also have a second bequiet pure wings 2 fan for the air extraction at the back of the chassis.

The CPU is running at 35° and at 55° in charge (after IntelBurnTest 2.50 running for 30 min).

 

Do you think I will be able to oc it correctly with this system? 

I was thinking about something like 4.5GHz with a V-core of +0,020V. Do you think this is realistic? What result did you get with such a system? What result do you think I can get?

Thank you for your help   !

Excuse me for my bad english, I come from France.

Sanybrdige chips overclock extremely well. I have a 2600k OC'd at 4.4GHz with only 1.34v on the vcore. I could go higher, but found no need/reason to. My CPU cooler is a Corsair A70, which is comparable to your CPU cooler.
