Product Care

Backplate electrically isolated

The TechN backplates for our AM4 water block is equipped with a thin foil that protects electrical components on the back of mainboard against shorting. It is easy to overlook. Please do not remove this foil. 

We strongly recommend to use the TechN backplate for optimal contact pressure of the cooler. Even if the original backplate coming with your mainboard might fit. There are certain mainboards with incompatible circuitry on the backside like the MSI MPG B550I Gaming Edge WIFI. You can use the original MSI backplate on your own risk. 

Deposits, staining on the cooler coldplate

Some users reported stained coldplates after some weeks of use. In most cases we singled out not using proper coolant as the issue. When using distilled water, it quickly takes up ions from the inner copper surfaces of radiators and deposits them on the coldplate. The use of corrosion inhibitors prevents this.

Acrylic and Alcohol

TechN water blocks use acrylic components that are attacked by using alcohol based cleaning fluids. The alcohol leads to microfractures and cracking. Instead of Isopropyl/Isopropanol you can simply use soapy water and a toothbrush 

This also applies for diethylene glycol that is found in some anti freeze automotive products and might be used as a coolant for its anti corrosive components
