Has anyone added any form of cooling fan to keep the charger cool?

I'm thinking of adding a couple of 12v PC fans to add some cooling.
 
Renogy DC DC 50A

Not having any issues but monitoring it on the app, it can get quite hot when running at 50A.
Do you need the full 50A? I have my Victron version wound down to 40 but it probably doesn't need to be as high as that really.
 
The guide for the battery says to charge it at 50A, but yes I could reduce it to 30A or 40A.

It's never indicated that there is any issue, always charges fine.

Just an idea I had was to add some air flow.
 
I the XS50 in both vans.

I run them 25-40A. And they stay cool.

Agreed at full 50A they get hot.

FYI, they have a xs70A version coming out.

I wonder if that runs cool at 50A?...20A under the 70A max?

Nothing stopping you from doing, but you’re probably solving a problem that doesn’t exist. If the kit is happy as it is, don’t over think it.

Does the app tell you how hot they get?

I've seen the Renogy at 65-75c
 
I wonder what temperature the Renogy would get to before it started to throttle the output.

I'm going to drop it to 40A on my way home and see what temp it gets to.

My plan is to add a couple of 12v PC fans above the heatsink of the charger to see if that makes any difference. Shouldn't take much to do, the power is already there.
