Title is basically the post.

I've went ahead and built my PC ahead of getting the GPU and have realised that I'm going to potentially need more space for my GPU as there's little to no room for most AIB GPUs out there aside from EVGA and the Gigabyte Eagle. I currently have about 41mm-42mm of space for a GPU which means the GPU will be sitting on the fans pretty much - Way too close for comfort that. If I get a 15mm fan, I can comfortably fit 41mm-52mm GPUs. (RIP the other three A12x25 I bought)

Between these two fans (Arctic P12 v NF A12x15, how do they perform? I've looked at videos and while that's all well and good, I want to know people's experiences with these fans, if they've had any.

Many thanks in advance!
