Hi everyone, first time here. I currently have a koolance exos (1/4" one) and was planning on upgrading away from it. It was my first time at WC, seemed easy, and I have ZERO room inside my case. Had pretty good reviews so I went with it. However, the exos is just not cutting it when I start upping the vcore. I was looking to go with a 1/2" setup using the mcp655 but the pump wouldn't fit inside my case. That leaves me with the mcp350 with a 3/8" setup. Was going to use the BIPII (low noise) with a radbox and put it on top of the case but that has 1/2" fittings. I believe the PA120.2 and MCR220 both have 3/8" fittings but it says they have brass cores?? Wouldn't that cause the same corrosion problem as with the exos's and it's aluminum core (aluminum rad-copper block) ?? What would be the best block to use with the mcp350?? Read the Storm is best used with the mcp655. Appreciate any help/advise with setup. Silly question, will temps be that much better compared to the exos even though I'll be using 3/8". TKS.
