Where as I've got a chip that idles at 50-60'C and hits 95'C when given any challenge (normally Handbrake but also hits 85+ gaming) with the Wriath Prism cooler even after replacing the thermal grease and making absolutely sure the heatsink is well seated :-(
My case airflow is 2x140mm fans in at the front, 1x140mm fan out at the back. The upper front fan is almost level with the exhaust fan. The lower one is set with it's top about level with the top of the graphics card so in theory it is sending cold air to the GPU fans.
The more I'm reading about AIO coolers, the more I'm leaning towards getting the Noctua NH-D15No need for the expense and hassle of an AIO, in my humble opinion!
