The ebay/no name fans need to go, 100%. Proper shrouding is a must with good electric fan or the stock clutch fan no way around it also. Consider mixing your fluid 80 water / 20 coolant with a full bottle of water wetter in. Coolant is actually a misnomer, the green stuff is antifreeze and acts as exactly that. It doesn’t aid in cooling. It does have anti rust properties tho so when you mix with a lower percentage of it DO NOT use distilled water. Tap water or hose water is better; the distilled water will be able to pull ions from the metal inside the block and cause corrosion faster.

This is what I’ve done on all 3 heavy track use race cars I’ve owned and never had a cooling issue ever.
