I got my Alphacool XT45 240 radiator today, and did a test fit of the important parts which i could have issues with. And the Define S had just enough room to house my hardware, my only real issue was/still is routing the tube comig from the 240 rad in top to the 360 rad in the front - isn't barely any room to route the tubes cleanly as fittings and tube bend radius takes up more space than i though, to combat that i have mounted the 240 rad in the mess top and not the predrilled fan holes, but it seems to work fine for the 5 of the 8 screws but the remaining 3 i'll have to drill some new mounting holes.
I'm tempted to cut the Define S's top moduvents so they fit around the installed fans, that way i avoid dust falling into the case through the top. I also have to think about cutting some of the mesh in the top under the fans away to improve their pulling force, the fans will probably be 2 of my 3 NF-F12 1500 rpm fans and not the NF-S12 fans though they would be fine on the low FPI radiator.
As for the one part of the build that have giving me the most worry, the clearance between the GPU and the pump/res combo. But it seems the case is just big enough for my plans to work out fine, as there is a good 3-4 cm between them.
And i'll have to make a 1 cm extender mount for the pump/res so i can have pull fans the inside of the 360 rad, but it's a easy and dead simple task of cutting a piece of plastic and drilling 4 holes in that, and getting some longer screws for the mount, but those are the same as the 30 cm long screws radiators come with and i have alot of those.
And here is the tight spot that caused me to rethink the mounting for the top 240 rad.
I also found some more pictures of the ram heatsinks i'm getting, just imagine those with a black base and red fins
That's all for now, i'm limited until i get my fittings and fitting + coolant, that should be some time next week.
