EKWB EK-XRES 140 Revo D5 RGB PWM
Question about EKWB EK-XRES 140 Revo D5 RGB PWM
Is it made of aluminium on the inside or only on the outside because if it is made of aluminium it reacts with brass and copper.
I mean it is completely made of aluminium
No, it is not made of aluminium (logically in this price range). Nevertheless, you should always use liquid with corrosion and bio-protection.
