Attention to Scarlet Red....
I have been using this liquid for about 5 months.
It has discoloured everything and has become transparent over time... This also means that the matt colour is stuck everywhere in the components and the expansion tank.
Including deposits...
Great colour but not recommended...
Had Scarlet Red in my Loop for 1 year without problems. Maximum temp. in my loop 34 Celsius and no aluminium components installed. If you have aluminium in your loop, this is certainly the cause...
Hello Fernando, this sounds like incorrect loop dimensioning. Have you checked your coolant temp. under full load and how long you maintain this temp.
If the coolant is heated too high over a longer period of time, it will start to decompose. This is especially the case if, for example, your pump generates too little flow. Then the CPU and GraKA get too hot, which causes the coolant to decompose and clog your components. This in turn leads to exactly the problem you describe.
This is a well-known phenomenon, especially with milky coolants. This also happens in cases where the loop is too small and therefore there is not enough cooling capacity to keep the coolant at low temperatures. If overclocking is then added and even more heat is pumped into the loop, this error pattern is pre-programmed.
I have been using Scarlet for almost 11 months now (max. 12 months prescribed by EK) in my TT Core P5 without any problems at an idle temp. of 28°C and 39°C under continuous load. My GraKa, CPU and MoBo are all in the loop. The system is overclocked by 35% overall. I have installed an EK Coolstream PE 480 and the EK-RES X3 400. This gives me about 1500mm of coolant in the system and, in combination with the large radiator, sufficient cooling capacity under all conditions, even in midsummer when it's a bit warmer in the room. The EK-D5 pump runs at just under 55% (constant) and delivers approx. 825L/h (1500L/h max.). Four Corsair LL's (120mm) flow through the radiator, running constantly at 750rpm (1500rpm max.). Both pump and radiator cooling still have free capacity.
If all this works for you, and you don't have any hot spots in your case, then you may simply have got a bad mixture.
