Mini-Chiller For My 3Litre Shrimp Tank?

[AquaPit]

Currently im using a cooling fan to maintain the temp at 26deg celcius..

Should I be using a mini-chiller instead?

Appreciate if anyone can share the pros and cons of both a cooling fan and a chiller.. TIA!

Aquarium chillers do exist but I have never heard of one sized for anything below 10 gallons.  A Peltier cooler would work but I don't know if any are made for small aquariums.

I saw one online..

But it must be used with an air pump..

Im still unsure whether I should use a mini chiller...
