Best strains for hot temperatures

[Northlight®]

Hello there.
1.st of all I apologise if some thread allready exist (I was unable to find it).
Im new in this business.
I have problems with high temperatures in my grow tent.
The temperature goes over 86F (30°C)over the day even if i open all the bottom air strips.
1.st ... If i put a small fan to rise the circulation of air will be helpful?
2.nd ... Can you please suggest me some strain that is viable for hot temperatures?
At the moment im waiting for my Auto Northern Lights to pop out
3rd ... Is this strain good for hot environment?
My set up is the following :
Grow tent 4*4*6.5ft (120*120*200cm)
Hps light 600w
Air extractor is a TT 125 with up to 280m³/h with charcoal filter.
Air intake (forgot the brant) up to 155m³/h
