Hi I have had my wc for about a year now putting 3 drops in monthly I have noticed my water stoping where the CPU block is and it gets hot to the touch I have also noticed it gets so hot it makes the hose leak(killed my psu) I also noticed that I do not hear my pump res but my rad is working fine... What can cause this? Is my pump done? It's a xspc raystorm x20 750 v4
