will i get problems with heat?

HI. Im setting up my new grow room but im woried i'll get problems with heat.Im using a 600w hps in a sealed room that is 2mx2mx2m i have a 150mm inline fan witch will be extracting air through a carbon filter,i will have a passive air intake coming from outside(uk )so its going to be cool air. Any thoughts .

As long as you got an air coolable hood bro with the exhaust going outside of the room your growing in you should be fine bro specially with cold fresh air coming from outside ya know. that room really isnt that small so oyu should be fine...thats my opinion on it
