r6v freezing alot, any tips?

while playing r6v myxbox has been freezing alot, so i have to restart it again, anyone got any tips on how to stop it freezing? i think it may be overheating but its not near anything and has got room on every side. i have read before that the "brick" gets hot so it freezes, is there anyway to cool it or any tips in general to help.

thank you

I placed my 360 on a grill cage therefor it gets ventalation from all sides and collects less dust.

You may have dust cloging up your fans try using a vacume to get rid of the dust but do this with caution.

I agree probly a scratched disk although with my xbox it seems to freeze less the more spare memory i have.
