Overclocking should always come with a disclaimer as follows:

Cooling always plays a role, when you can get it running cooler it will usually do better clocks even at the same voltage, leaving more headroom.

Ok.It's runnig at 835 mhz now!!! increased from 1100 to 1113 runnig stable.But temps now reaching 88°C. I strapped a 120mm cooler directly on the heatsink.
Anything else I could do to cool it even more?

i'm still concerned about my PSU. Is it enough? My 2500k is runnig at 4300 mhz.
