The stock fans that came with the case, although I installed filters on the fans and took off the acrylic cover because the cases airflow isn't great. haven't upgraded anything yet, as I didn't start working until about a month later then i expected. will be starting to shop for fans in the next month or so.
I will be getting fans and a better cpu cooler soon. I dialed back a couple hours after posting past night as well to stay below 75!
