The build was an 8700T/ Asus Turbo 1080 Ti setup I pulled from a dan case. The rads were dark side 240mm crossflows with 17fpi.
I had and wanted to use 25mm noctua’s originally but doing some measurements, I didn’t really think I had the room. The front rad would’ve easily been possible, but I would have had to move the pump bracket to the top fan. This would have worked but I liked it lower to give me more room to get to the reservoir top easier when the tubes and cables were installed.
As for the bottom, i made some brackets that bolt to the rad and raise the stock hdd bracket included with the case up 20mm from the rad. That hdd is a Seagate 12tb and it is thick. I plan to get another when I do an incremental upgrade this fall. The stock bracket can not fit 2 of them so I also cut some mounts to where I can bolt a second one on top of it. I will have a couple mm to spare from the top of the 2nd hdd to the bottom of the GPU support bracket. So I’m a bit too tight to fit in the 25mm fan. I could probably have shortened the hdd brackets to 12mm and squeezed it in there but I was worried about the radiator heat warming the drives up.
Edit: I also agree with your previous statement about having fans in pull but I’ve preferred push since I had a loop in an air 540. Plus I tried to hide that horrible color scheme and it makes it easier to attach tubes with them on the other side. During regular use the noise is inaudible to me, just gets a bit louder than I care for gaming. This isn’t a big deal because it really isn’t loud, no louder than the dan case at least, plus I’m 90% of the time wearing headphones when gaming.
