Alright guys I got my Water cooling system up and running. It works wonderfully and with no leaks. It dropped my temps by an average 15c to 20c While overclocking and stress testing. Heres my Question though..... my Bard Size that came with this water cooler is G1/4" to 1/2" barbs x6. Since my Cooler Came in a Kit it came with 7/16" ID x 3/8" OD Tubing. But I would like to switch over to some 1/2" Tubing because of the fact that 7/16" is hard to find locally. Would this cause any problems???? If so what would be some other suggestions of sizes that I could use? With out hindering Flow or worries of the tubing slipping off? Sorry if this is a noob question but I have always had hard time visualizing sizes.
