possible to get more fans through pci-e x1?

My pc was bought premade (its an acer desktop) and no idea what the motherboard model is.

I want to add some fans (and get new case to support said fans) because summer approaching and pc temps rising but looking at the board the only fan connector is the CPU fan.

I have all my pci-e slots used except my x1 (pretty sure its x1) and was wondering if they make cards to plug fans into or not.

You can get fans that use the molex 4-pin connectors from your power supply, or from the SATA connectors (I believe). You will not be able to control the speed, but they should still work perfectly fine.
Or, adapters, such as this one: https://www.newegg.com/Product/Product.aspx?Item=9SIA4SR1PN3978&ignorebbr=1&nm_mc=KNC-GoogleMKP-PC&cm_mmc=KNC-GoogleMKP-PC-_-pla-_-HI+-+Conduit+%26+Fittings-_-9SIA4SR1PN3978&gclid=CjwKEAjwja_JBRD8idHpxaz0t3wSJAB4rXW54GFVEv8ed51Xw679PBCBj9XX98FiAerI9AAHBlGCyxoChBbw_wcB&gclsrc=aw.ds
