Review on GOOFIT Square Radiator Cooling Motorcycles by Tony Wilson

This was an experimental addition to my bike to complement the standard 'open air' oil cooler. My bike is the latest Triumph Bonneville 865cc vertical twin air and oil cooled DOHC engine. Unfortunately, I think the manufacturer's specifications for this fan are exaggerated. Although the airflow rate isn't disclosed, I'm estimating it to be around 175 cfm. I tested the fan with a 12V-3A DC power adapter before installing it on my bike. It runs from 8V to 14.5V DC and of course the fan speed is proportional to the applied DC voltage. The current consumption at maximum voltage is only 1.0 A. The specifications state 2.4 A; apparently much higher than it really is. Due to this reduced operating current, I protect the fan in my application with 3 A. There is another rather serious inconsistency in the manufacturer's description. This fan is NOT designed to pull air as stated in the product description. The exhaust fan mounts flush with the rear (engine) side of the radiator. This fan is actually a "pusher" so it should be front mounted. This is done so it can draw in a high pressure airflow (cold outside air), which forces more air through the radiator and removes heat from the other (exit) side. cooler heat exchanger. I installed it on the front of my bike's oil cooler on the fresh air side where I could mount it and also keep it away from the hot exhaust pipes on the other side of the cooler. This mounting configuration is still not ideal, but can be more efficient for general thermal management purposes. The added benefit of front mounting is that it avoids overheating the fan from radiant engine heat and hot exhaust fumes, but is now fully exposed to rock chips and other dangerous debris being lifted off the highway. This fan does not come with a finger guard, so it also poses a potential safety hazard. In the end, this fan "works" (or can be made with a little ingenuity) and is only $19 with free shipping. However, I wish it had a more powerful 12V DC motor and a slightly larger diameter and/or thickness. As it stands, I think the airflow will hardly be enough for my application. I'm also ordering a 5-7/8" all-metal fan from the same manufacturer, part number 038-016, offered by Revain PRIME. for $22. This alternative fan promises to be tight with a more powerful DC motor - still doable. It probably would Better control the temperature of my bike's air/oil cooled motor.
