RX 240 / H220 Radiator
After seeing some great results with the RX 240 I stepped things up and added the radiator/reservoir combo from the H220 back to the loop. I mounted it in the top of the case and just used the Swiftech fans that come mounted on it. Again I had issues getting the loop running and bled of air, but after some persistence and lots of tilting the case in various ways I got it working well.
Here are the results:
Ambient temps: 21.66C/71F
Max overclock: 5.0 ghz/1.480V vCore (Did not lower, just a minute fluctuation)
IBT temps: 74.25C core average
With the same average results of the RX 240 by itself it doesn’t appear that adding the Swiftech radiator back did anything. However I did see a drop in the highest core temp down one more degree celsius from the RX 240 alone.
