Case Fans - what to do?

So I bought this PC here a while back and from the start I found the cooling fans to be extremely noisy which I traced to the AIO pump not spinning up properly when plugged into the CPU Opt header and a large amount of negative pressure within the case as a result of all the fans sucking air out. I've fixed the pump by plugging it into the AIO Pump header and recently I've taken out the rear fan which has helped with temperatures enormously. Seems that the fans were fighting each other and all the GPU heat was going straight up into the AIO rad but now I've got a decent stream of warm air from the front fans and a much cooler AIO rad.

The question is what to do about the back where the fan was. I don't think Kolink make a reverse version of the installed fans but the gap looks quite big with nothing there. Does anyone know of a suitable reverse fan that would look good in that space so I can set up a push pull system?

Leave it without one.

Definitely an option - maybe I'll get used to it.

Or flip fan around so it flows in the opposite direction?

Tried that - didn't like the look of the back of the fan.

Thanks for the suggestions. The Antec one looked pretty good but they're not easy to track down. I found this one that might work though and could look ok at the back. For filtering I've got some filter mesh thats already applies to the bottom half of the back and I can put that right up. Hopefully with a fan pushing in I can increase the case pressure a bit more and optimise the flow further.

I suppose I could flip the AIO rad fans. Maybe not ideal since the rad is at the top but it's free and since there is already a mesh filter on the top it would improve dust management.

It is perfectly fine to do that.
You could also consider placing them on top of the radiator, so that the RGB is (presumably) is more visible on the top of the case. I'm guessing about that, since I don't know your case. Fans are also sometimes quieter when they are pushing rather than pulling, so it may also make a sonic difference. Try all the options.

Might do that then. If I have to take the cooler out it's would be an opportunity to repaste with some better thermal paste too so it would probably be worth the effort overall.
