So I've decided to go water-cooling for my CPU for the summer. I am doing a custom kit, and I would like to know if I am missing anything crucial or if there are any incompatibilities. For my water block, I am going to buy the XSPC RayStorm High Performance Acetal CPU Liquid Cooling Block. For the radiator: XSPC EX240 Dual 120mm Low Profile Split Fan Radiator. For the pump: Phobya DC12-260. For the tubing: XSPC FLX Red UV Tubing 1/2in. ID x 3/4in. OD (19/12.7mm). For the reservoir: MCRes-Micro R2 SSF Hi-Flow Acrylic Reservoir. I know I am missing two fans for the radiator and the barbs. How many barbs will I need? Microcenter has what appear to be plastic barbs (http://www.microcenter.com/product/391535/G_1-4_Barb_Fitting_-_1-2_ID_Matte_Black_(BP-MBWP-C01)). I would like to know how many barbs I will need for my CPU loop and if they're the right size. I would also like suggestions for cheap fans. I don't care about noise (I wear a headset) so I don't need to spend money on silence. I would also like to replace the stock blue LEDs on the water block with red ones. If someone could explain to me how that is done and where to buy those LEDs that would be great. Thanks!
