I considered making a build log, but I got too excited and just started putting stuff together. Ordered 3 st30 radiators and strangely 2 of them came in early. So I got all the stuff in order to put together. Here's just a quick progress picture:
This is my first time with Alphacool and I have to say I am very impressed. Build quality is truly the best. My only very minor complaint is with the logo stickers, just wish they would stick better. I am excited to see what kinds of performance these ST30's can do. Looks by the size I could have easily gone with the XT45 series however I will be happy with the thinner radiators. Having experience with the phoyba g-changer which is essentially a UT-60, I don't think thick radiators are really necessary.
Other notes: My first 540 build I had a few issues finding a good location for the pump. I am using an XSPC D5 tank reservoir which is just sitting on some foam pads on the power supply. I need to likely figure out some better way of attaching it (perhaps adhesive). Also my first 540 build I managed to scuff up the outer plastic fairly bad. Going to try to not do that again...
I have 8 AP-15's and 2 XSPC 2000 rpm fans. I could potentially use all 8 on the 360 and 240: 360 in push/pull and 240 in pull. Then use one of the XSPC fans on the back single 120 radiator. However I will need to order more screws as I don't quite understand Alphacool sending 35mm screws (too long). But my thinking is that push pull performance on the ST30 isn't really necessary. I plan to bring the ap-15's down to around 800-1000 rpm. My current plan is to have one set of fans on the radiators which leaves me with 2 spare AP-15's. Perhaps I will order additional screws later.
Final thoughts: this case truly is a masterpiece. I was so excited when the Phanteks Enthoo Primo came out and I never even considered the size of it to be a problem. As amazing of a case the Primo is, it is just entirely too big for me. The 540 seems so much better over the newer cases like the h440, corsair 450d, for reasons like it's unique design and gigantic window.
