So I have have a ver 1 Corsair h100i that has sat on my i5 4670k since 2013. I recently upgraded using the hwlb to a mix of the high and midgrade system (2700x, x470f, rtx 2060). I was really wanting to reuse the h100 in my new system. Then I realized that the pump and all the fittings are 5 years old. I am just asking for an accident. I spent good money on these parts might aswell invest in their protection.
