Help with case airflow

[Ultam144]

I'm pretty sure this belongs in this section. Earlier this year I put together a build with a Cooler Master Silencio 352. I really like the case, but recently upgraded my GPU from an r9 280 to an MSI r9 390, and it appears to have issues providing enough airflow for such a hot card. When I run a taxing game such as Witcher 3, the GPU runs up to the mid-90s (at which point I quit the game). However, when I take the side of my case off, it tops off around 82 degrees.

The case comes stock with two XtraFlo fans (one intake in the front, one out in the rear). I added another (albeit small) fan to the front for better intake, but it didn't seem to help. There isn't much room for other fans (the one at the top would be blocked by my CPU cooler).

My question is this: could the problem be remedied by simply replacing the stock fans with higher quality fans, or should I look into getting a new case better fitted to deal with the heat? If so, what might be a good case to look at purchasing (mobo is mATX)?

Let me know if any more info is needed.

First of all, you have to check the fans points the right way.

Assuming there´s they do, you want to check fan settings (automatic or locked speeds?) also physically inside the cabinet, inspect it for bad airflow (cables, dirty fans and filters, un-nessary PCIe cards etc).

Fans mounted on the side of the case can be useful - but they can also cause problems for proper airflow. If they are set too high, the airflow goes into a turbulence instead of pushing the hot air out. More fans doesn´t necessary mean better cooling.

Then you want to open the front door so the intake fan gets free airflow.

The rear exhaust should also have space to push out the heated air, so it escapes properly

The fans are definitely pointed the right way. The two front fans are plugged in directly to the PSU, so they're running full speed. The one in back is plugged into the motherboard, but it's also set to run at full speed. When I put in the new fan, I freed the space of cables and such, so there's nothing blocking airflow (other than the drive bay blocking part of the lower front fan, but that doesn't move). Opening the front door has little effect on temps, and the rear fan has plenty of space to expel air.

I did, however, notice that the new fan I installed pushes significantly more air than the stock fan. I can hardly feel the air moving from the stock fan, but the new one moves quite a bit. Might try swapping spots so the new fan flows more directly onto the GPU.
