Currently I am running a single loop in this config.... Pump/Res>CPU>360Rad>2xFull GPU Blocks>240rad>(Back 2 original) Pump/Res and I noticed in my setup it is going to make it difficult to drain. So I am considering adding a t-line to help with that in the future. But I have never added a t-line and I had a few questions before I did.... 1. Is it a good Idea to use a res and a t-line in a single loop like this? 2. Will it cause a decrease in water movement? 3. Will it cause a lot of problems to bleed my loop because of it? 4. If all of these are not problems ..... where would be the best placement for it? Thanks in advance guys!
