Tuxing Official Store in the US just brought in the TXEDT033 model. I've had my eyes on it for a while but finally ordered it today when I noticed it was reduced to $999 with free shipping on Amazon. This model is just like the 032 but it has 3 fans behind the radiator instead of only 2. I know there have been multiple posts on these but I have a few questions. Lubrication - Royal Purple, SECO 500, or SECO 800? Cooling - Royal Purple ICE, Water Wetter, or 50/50 anti-freeze mix - or some combination? Distilled water? What is the unmarked on/off switch on the top for? I did see Brian Thurman's posts on the 032 and will follow his lead or contact him if I have questions, like for the "T" fitting. What should I do initially like hose rerouting, tightening of fittings, etc? Any answers or links would be appreciated!
