The fans are directed at dead space with a lay down radiator and no hood vents, especially with no air flow under the car when at a stop, perhaps consider re-orienting the radiator as near stock as possible
One aspect that is often overlooked, especially with shrouded fans is that fan efficiency is impacted by how far the fan blades stand off the radiator, if I recall correctly they are best at 3/4". I spaced my shroud off slightly to achieve that.
