As the title says, in your opinions can a 200cfm fan efficiently cool a 4x4x6.5 grow tent? Im using a 600w light if that matters
 
Im using the same size tent and light. 200 cfm is definitely not enough. Keep that fan and use it as an intake booster fan. You can find some 400 cfm fans pretty cheap now but remember you get what you pay for.
 
I use the same size tents. When I ran 600s I used a 190cfm 4" inline to exhaust the tent and cool the light in each tent.

Now I run 1000s and use the 190cfm fans to exhaust each tent and have a 500cfm fan to cool each light. its all depends on the temp of the room the tents located in but I never had a problem with temps when I ran 600w hps/190cfm fan combos.
