Is it overeating ?
If so, someone had the great idea to turn the SP20 on the side so the heatsink doesn't stand on the side but on top. You can try that.
I know the new version SP20E has the heatsink glued so ... not sure if yours is glued or not.
You can try, it's free

Thanks herb not over heating and heat sinks glued on had it on side b4 maybe give it another go
