Alphacool Eisstation Top Discoloration

[hhamama66]

The top on my Alphacool Eistation has been showing discoloration and today I noticed what could be a micro crack forming all around the top. I have no idea what could be causing this. I have a temperature probe in the bottom of the reservoir and the water doesn't exceed 35 C and my components don't exceed 45 C usually. I run my loop with about 30% antifreeze mix and have two hardware labs radiators, two Alphacool blocks, all my fittings are copper and I'm using the EK neoprene tubing. This is the second reservoir I've purchased, the first Alphacool Eisstation had micro cracks forming all around it. Since I've replaced this reservoir once already, I took apart the blocks and decided to check and see if there's any impurities in my loop and both blocks were clean. The reservoirs didn't have anything in them either and the coolant (distilled water with about 30% antifreeze) looked the same as when I first filled the loop. Any ideas on why this is happening or should I admit that the Alphacool Eisstation uses terrible plastic and get a different reservoir instead?

I really don't think you should be using any kind of antifreeze in a loop

Should contact the manufacturer and tell them what you’re doing, then they will tell you why it’s happneing.

Its probably reacting badly to the antifreeze.

Contacted Alphacool, they said nothing about the antifreeze and just sent me a new top.
