Thank you Beer, will try

But there's another problem - i have mistaken the models due to my stupidity. So the temparature for the above model is only 58 C in real life. So i gone digging :)

Thank for a reply.

No, i dont, but i do not know if its necessary, because it's having a temp of 250 C and i dont think that it would fall to 60-70 C. But i should try giving it some 300...
