There is no side fan included...there's a spot to mount a 120mm fan though and I had one mounted there for a time and didn't have any problems....
Honestly it's not really needed...it has 2 120mm fans sucking in air through the front....1 120mm exhaust fan in the back....the PSU sucks air out the bottom back and a huge 200mm exhaust fan expelling hot air from the top...
When I added the 120mm fan on the side I didn't notice any difference in gpu temps...
Well I got it. Everything looks good and is running much cooler... I also swapped out my MB with one I ordered a long time ago and just got in today. After I got everything setup I ran 3dmark06 again and improved my score by a couple hundred points...
My tuniq tower should be here in a couple days. Then I'll be able to push it a little. We'll see...
this case is the best!! i mean it already has 4 fans, and u can still add another 1 for xtra cooling for ur CPU and GPU, i mean those will make ur system run way way way cooler!!!
