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.
The reason your temps went up after you replaced the tubing was because you used smaller diameter tubing. Also, I’d be interested to see the results obtained with the full loop (sans second radiator) if you used tubing matching the original dimensional specs. Using smaller inner diameter tubing adds significantly to the flow restriction of the loop, which can (and will) negatively impact cooling performance secondary to degradation of pump pressure. A good article, though. It’s refreshing to see a review site hold a manufacturer to their word. Swiftech’s was that you could add cooling blocks to the H220, and, indeed you can. I’ve been wondering when one of the AIO producers would quit screwing around and switch to copper radiator. Kudos to Swiftech for taking that next (if obvious) step.

Glad you enjoyed the review!
Actually though we did use the same inner diameter tubing as what came with the cooler. Ours simply had smaller outer diameter. This really should not have any impact on temps or flow at all. It was very interesting that the temps were negatively impacted by the change.
