Not tested on AMD platform. Why?
$180 should warrant a full copper build. Sadly, not the case here.
No AMD build because when this test bench was originally built AMD didnt have nearly the market penetration and OC as it still is was shit making it a not useful test bench. However the latest batch of processors are far better in that regard. So as I literally posted just above your post, AMD + Intel updated test benches are coming along with noise normalized performance.
As of right now I have the largest overall data set of CPU coolers tested on a modern platform. Right now reviews sit at 66 coolers tested.
As of right now I run 4x tests 3 times at stock and OC thats 15 mins per test. That works out to 6 hrs of benchmarking per cooler.
New benchmarks for both AMD and Intel platforms will take 14 hours. Now I am carrying forward 15+ coolers to start that works out 210 Hours just benchmarking coolers for new platforms. If I carry over more coolers that means more testing. I feel 99% of users have no idea how much time it takes to acquire this much data. So yeah no I was not about to add a friggin AMD bench halfway through a cycle just for shits and giggles so I can retest 60+ coolers at 6 hrs each its just not gonna happen lol.
Also keep in mind I maintain a set ambient temperature, have photo work, writing, then of course if there are issues I have to work with companies etc. Even for something like coolers its not a super easy process. I check thermal paste spread, how well the mounting process works. Issues like Corsair's A500 not mounting properly due to capacitors on the mobo hitting the heatpipes etc. They all add more time / complexity etc.
If you want AMD results, I would suggest waiting for other reviews for the time being. Someone will undoubtedly test the cooler on AMD. For those wanting AMD testing from me well your just gonna have to wait patiently.
