Problem is pretty basic. I have 2 tubes running through my computer. 2 are 3/8th's tubing and the third is 5/8ths tubing. I believe I misclicked when ordered the barbs but I went to the hardware store and made it work (between the rad and res). the problem is the 5/8's tubing is thinning out, and by that I mean it goes from a perfect 5/8ths circle to maybe 1/4 tall and 1" wide. happens over the course of a weeks time and I've replaced the tubing twice already. thoughts?
