92mm GPU cooling fan mount for PCI(e) expansion slot

I attached a universal waterblock to my GTX 1080 but I wanted more than just the little stick on heatsinks for the memory. With this, the fan is centered over the GPU and cools all the surrounding memory and also gets the VRMs somewhat. I'm using this now in my PC and it dropped my memory temps by 30 degrees!

Most 92mm fans should fit fine. There is a little notch that can slot into a PCI slot, or maybe the PCIe slot. I think mine rests on top of the PCIe slot, but it's nice and sturdy
