With this blower, I only unzip about 4 inches of the top to allow heat to exhaust. Works great when using PLA and wanting to keep temps reasonable and keep dust / pet hair off your prints. When placed at the front top of the enclosure like i show in my pic it makes a nice stream right towards the print head, should help with part cooling some also.
This uses a 75mm USB Fan, 75mm x 15mm Blower Fan, 5V DC Brushless Cooling Fan $9.00 USD. You can get from amazon. https://a.co/d/1ACZiB8
