Not sure whether this CCI copper performs any better than the Sunon copper I had previously, but neither the CPU or GPU are thermal throttling. But I am using Conductonaut now, where previously I was using Kryonaut, so I was expecting it to be good.
The CCI version is a little less finished than the Sunon one, there's some minor padding missing around the exhaust fins and less black tape, but I don't know whether it impacts the thermal performance. It simply looks less premium.
Much cooler than the original heatsink, which enables 1080 to run at its 100% continuously.
My 17 R4 have been used for 4 years, with this product and thermal grizzly, can still run Metro Exodus at 50 FPS, under very high graphic of 1440p.
After installing, temps went down from 95° cpu and 91° gpu to 78 cpu and 70° gpu on full load.
I did overclock level 2 on cpu temps went up about 3~7°
Note: product may seem bended in the middle but I guess it's on purpose, I was worried too but it was worth it.
