Heat Concerns with GTX 970 SLI in Air 240 case

Build this PC recently, and trying to get the air flow in this case possible. Originally my idea was to pull cool air in from the front of the case with H100i, then exaust from the top. And since the gigabyte gtx 970's exaust heat vertically so it make sense to blow cool air from the right side. However when I'm gaming the top card got max temp @ 81C while the bottom one is only around @60C, and the cpu runs cool always below 40c when gaming. So I changed the direction of the fans of H100i to the picture below(blow air out), now I'm getting temp @74C top card, bottom is still around 60C, but the cpu is 50-60C for the same load (which is not even max load so it lowers cpu OC potential).

While I understand that 74C is probably OK for gpu but I want to use this PC for a long time and want it to run low temps during load times. And four outake fans makes the case has very negative airflow. So any suggestion of fan config will be greatly appreciated.

For those who doesn't know about Air 240 case, I'm using mATX so no fans at bottom, max two 120mm fan on top, two 80mm fan back(which I don't have), and I have my H100i in front(can't be on top otherwise would be perfect)

Also is bending the pipe slightly like in the picture fine??

Any help would be appreciated!!

You can give it a shot. But the Gigabyte cards are highly clocked and putting them in SLI and in an mATX case is just not ideal. The cards will turn their clock speed down in order to maintain a temperature so you actually aren't getting the full potential out of both cards.
I literally just had a thread with a guy about the same problem with the same 970's in the same case. Only he had an H80i. I will find the thread in a second. It ended up being that no matter what fan config he used he could not move the temperatures from 80c.

Sorry I don't know why my tag following doesn't work anymore.

Yeah I saw that thread, but it didn't really help my situation so I decide to post mine. I wish I have gone with a H80i so I can have cool air for the GPUs. Now I think I will stick with this config (front out-take) cause it takes a lot of work to switch back and forth to test, and also I'm getting a 80mm intake to put on the lower back slot to see if it help lower the upper card temperature a little bit.
