I had exact same problem. Images are included. Solution is: a) Clean cooler block and all parts from rust and dirt. b) Get rid of original yellow liquid - it contains water. Clean well whole Enermax system either with air compressor or water from bathroom hose. c) Put standard G12 red antifreeze instead - without water (this is tricky because you need to fill whole system - pipes and block and cooler) and to avoid air holes. I used suringe for that boring job. Explanation: 1. Water is THE best coolant. However it conducts electricity and that's the reason of dirt (bimetal corrosion). Algae or microorganisms can develop inside water. 2. With pure G12 red antifreeze there is no electrical conduction, and no algae or microorganisms can develop inside. 3. CPU temeperature with G12 may be max 1-2 degrees higher than water (eg: 62C vs 60C - on lower temperatures is 1 degree) - however G12 has less pressure on tubes regarding high temeperatures than water. 4. G12 + water is better on very low temperatures (less than -10C) but water is problem (see 1). I hope you will not have less than -10C in your room. (Pure G12 sustains temps at about minimum -10C to -12C, but mixed 50/50 with water can sustain less than -35C. But, as I said water is big problem!) 5. With original yellow coolant water pump max rpm was 3000. Now it's 2500 because G12 has higher density than yellow coolant mix (viscosity). Before cleaning my CPU temp was about 40-45C - normal work. Reason for that was dirt inside block. After cleaning and replacing original liquid with G12 temperature is between 30C and 36C. I hope someone will find this helpful...
