Tiny power supply external fan

My tiny converted server power supply tends to run hot!  About 120F according the temperature of the air coming out of the exhaust fan.  

So I decided to add a 12v brushless fan to exhaust the air below the charger stand.  To power the fan I added a 3rd pair of 4mm bullets to the output tabs of the power supply. 

I added a small tab to the charger stand to mount it with Velcro, so I could detach the fan and store it for transport. 

The temperature under the stand only seemed to lower a few degrees (90F to 88F?). I guess I'll monitor it more to see how effective it is.
