i think i got my answer. i dont have a northbridge fan and that could be the only reason for such high motherboard temp.
41°C could be normal for my motherboard in such high summer temps but still m gonna slap an 80mm fan on northbridge and tweak it with "Speedfan".
i wil also update the changes in motherboard temp after installing the NB fan.
Thanks n I really appreciate the help from you guys.
