Thanks for reply,
Zalman cooler fits there but width of heatsink surface slightly shorter than width of processor so in fact there is processor surface without cooler!!! and zalman 7000 runs with bios q-fan controller maximum at 2700 rpm!!! and i think this is the main reason for higher temp!!
Yes, you are very right about lower temprature. I am going to put back that stock cooler, a little noisy but safe!!
Thanks for advise
