it depends where the card is hot.for me it's hot on the side of em,at heatpipes,but its fresh on rear and anywhere. I had a pushing side fan that was only helping me of 1c,and it was a 250mm fan.I think it was more pushing the hot air towards the card than anything else.Anyway removed it for a CPU cooler. Actually ,i'm curious to see the results but i'm pretty sure this side fan won't give you much better performance. Don't break the great airflow of the 4 other case fans!
Also, if u have a pull CPU fan, it would be bad.I'm not a huge "fan" of side fans...
Fan of side fan, hahahaha
