It has been awhile since my last post, but I check in daily at TPU. I’ve searched around but I don’t really see any builds done with rigid tubing used to water cool, well not a full build as far as I can see. But I know the idea has been mentioned from time to time. So, I’ve been toying with the idea of completing a build with stainless steel tubing and since the opportunity has arisen I plan on putting this plan into practice. The build is overkill, but being a somewhat enthusiast, I couldn’t help myself and have already purchased all the gear. Build: Corsair 800D X58 Saberthooth Corsair AX1200 Gold Power Supply Intel 980x Palit 580GTX SLI Corsair CMP12GX3M3A1600C9 12GB (3x4GB OCZ 80Gb Vertex II (OS) WD Caviar Black 1TB (Storage) Samsung SH-B123A 12X Blu-ray DVD Combo Drive EK-CoolStream RAD XT 360 (TOP OF CASE) EK-CoolStream RAD XT 240 (BOTTOM OF CASE MOD) EK-Supreme HF Acetal+Nickel (CPU) EK-FC580 GTX Acetal Nickel (GPU’s) Laing D5 pump (INSTALLED IN DUAL RES) XSPC Acrylic Dual 5.25” Reservoir I plan on installing 3/8” stainless steel rigid tubing to all blocks accompanied with Swagelok compression fittings, 1/2” will be too bulky. Since the compression fittings are a tapered thread, I will have to re-thread each of them to a parallel thread and also cut them down a bit as the thread lengths are a little too long. I can get the tube and fittings for free, too expensive otherwise. Being rigid, there are a few negatives, mainly being non-flexible and also the conductivity properties of the tube. So in order to maintain the loop periodically I’ll also need to tee off a drain valve. Filling the loop will be done at the res. The water blocks will be in parallel purely for aesthetics and for temperature evenness across the GPU’s. As for the conductivity issue, all piping will be done in a fashion which shouldn’t cause an issue. The loop will be RES/PUMP – 360 Rad – CPU – 240 Rad – GPU 1&2 – back to RES/PUMP So I’ve spent some time in google sketchup to lay it all out with the closest dimensions and all should fit and hopefully look alright once completed. Let me know what you all think and any criticisms are welcome. I'll commence the build in about a week.
