Unresolved Prints on one side warping

I will have to order some fans. Anyone know what CFM I should be looking for?

 

The higher the better. Quiet fans are nice but they don't put out much CFM ~3-4

 

Ok, proof is in the pudding, except I can't truly tell, it was going so good until I unplugged my laptop to plugin a power supply to run the 4 inch fan, and low behold, my battery did not last 30 min and I forgot about it and my print stopped, almost finished. Least I can compare it to the one I am printing now with just the upgraded fan shroud.

 

Let me know what you find for fans, I think the stock one could be alot better at cooling, I am defiantly going to put a front fan on also.

 

Ok the results are in. The print that is not finished is the one that I held a fan on, you can definitely tell the fan helped the front edge, as that was the problem on this model. When I printed the full one it had a flap in the front about 1/8 inch long before it finally settled, so the fan is the answer to some of these models. The full one was printed at 200c/50, the unfinished 197/45, as I tried to compensate for cooling, I have not flashed my robo so I cant go below 197 as it could error out on extruder temp to low.
Here is my setup for a front fan for now, does not blow overly hard, but should get the job done.
