Cooling Fan for Finned Neu 1515

[VintageMA]

Not saying that I will need to for general short time (~10min) running, but for a setup that can run for 30-40 minutes I may need a fan to help keep the Neu from getting too hot in a setup with not a lot of air flow.

Anyone have a recommendation for a fan that can be mounted on a finned can 1515? Any fans that push a lot of air?

I saw this link for a Muchmore Racing HiRPM fan here:
