Default Do I still need a relay when using a thermal switch?

I am using this thermal switch for a fan on one of my fluid coolers: https://www.improvedracing.com/therm...00f-p-831.html


I'm so used to wiring up relays w/fuses to control electric fans (like for coolant radiators that draw 20+ amps), I didn't think that perhaps in the case of this thermal switch, that I may not need it.


The fan I'm controlling only draws 7.2 amps, that switch is rated for 10 amps.


Does this mean I don't need the relay in this case? I have a 25 amp continuous relay with a 30 amp fuse on hand, but if I can simplify my wiring, I'd like to. But on the other hand, if using a relay will make the strain easier on my electrical when it kicks on, then I'd rather go that route.


Thanks!
