I bought the MasterLiquid ML240R RGB 2 weeks ago I have a new pc with an 8700k CPU this PC is mainly editing and rendering videos. I tried overclocking the CPU to 5 GHz and it worked I even got more 5.2 GHz but the temps were 90 when rendering so I got back to 5 GHz and the temps were between 65 to 75. Acceptable temps,I got what I want and moved on a few days later I noticed a 30% jump at idle temp from 35 to 50 so I checked and thanks god I checked I don't know why but I went straight to the pump and I noticed green water on 3 of the screws of the copper plate and some between the copper plate and the plastic .I contacted support they were really fast I got a response same day to send it back from where I bought it and I did now i am waiting for a replacement to arrive in a few days. I am telling my story here so you can learn and be more cautious with AIOs in general. CollerMaster support was very good they did what they should do.
