Hi all I have my parts arriving today for a new Gaming PC. I’ve got an i7 9700k, cooled by a Corsair H150i in a Phanteks Enthoo Pro case. The only place big enough to store the radiator is at the top. I’d assume I’d be best using this as an exhaust. My question is - 1. If not ideal for the CPU, is this okay to use as an exhaust? Or should I change it to a H115i or different case? 2. If okay, should I be using a push or pull configuration to exhaust the air? Thanks, Connor
