ThermaltakePacific DIY Liquid Cooling System CL420 64mm Thick Copper Radiator CL-W193-CU00BL-A

These are thick and have amazing flow. I'm sticking to these from here on in.They cool my system adequately, running two of these in a loop, one for CPU and one for GPU.I use Arctic P12 fans and my system is whisper quiet.No complaints about performance at all, both CPU and GPU are overclocked and they run cool.Only caveat about these is that you need lots of room in your case.

I ordered this model back in April. I don't know if I got a really good deal or if it was refurbished. Either way, it works great and is holding and looks good. Runs with high static fans awesome under load my 6950xt and my rysen 9 7900x are running COD MW3 at 2k 165fps at 50C

This rad in combo with 3 artic p12 fans and bykski pump keep my radeon 5700XT cool at around 80 degrees (C) max at the junction (radeon thing), 55 max where most take their measurements even running at 99% utilization for extended periods of time.Size makes it difficult to install but that’s to be expected with this size of radiator.

This thing is a beast so be sure you have the real estate because with a dual fan push/pull configuration, she THIIIIIICC. Couldnt be more happy with performance either as im sitting sub-ambient at idle and only barely over ambient temperature with 100% synthetic load (wPrime) on the CPU. If you have the room for this beautiful monstrosity, its essentially the core the of the last cooling solution you'll ever need.

I'm more than happy with this radiator. I have a 3900x and Radeon VII in a custom loop and it transfers heat very efficiently. Will be using their rads from now on.
