WTB Looking for a few basic 120mm fans


I recently got a barebones ATX case for 1.8k and am looking to add some cheap fans to it.
Don't need anything fancy, just some basic 120mm fans if someone has lying around.
Case currently only has 1 x 120mm fan which isn't enough.

Looking for at least a pair, though more are welcome. I'm low on budget, so not looking for expensive fans at all. Just something basic ones.
