2002 Mazda MPV new radiator/then evap...now fan noise all the time freaking me out

I had the radiator replaced 2 mos ago. Then a week later, check engine light declaring that evap needed replacement. Done. NOw the van’s fan never stops working. Sometimes I stop for just a minute and leave the engine running and it sounds so loud like it can’t breath.

took it back to the mechanic, they said it is fine, normal.

All I know is before these two repairs the fan never went crazy like how it does now. I wondering, is this really ok? It does’t feel ok!
Thanks for any info
