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

Looks really nice in my thermaltake view 71 case. Took slight modifications to fit it. Would recommend.

I Run an all copper loop, this rad is copper aswell.The good,Great performance, this cools an 8700k overclocked to 5.2ghz, max temps 65~70C in peak moments, drops to 40C or under regular use. idles around 30C.Doesn't restrict flow fate.Thick, at 64mm thick this rad is only for cases that can manage it.The BadIt's so think im surprised its not multiport, 4 on top and 1 drain on bottom. (my Phobya rad is multiport, 8 on top with a drain on the bottom)Painted a little too well. the first 3/4 inch of fins is painted black, i'de rather see the copper, and have only the very edge painted.Needs a serious clean new, make extra sure to flush it well before adding it to your loop, mine had a bunch of particles in it.fin density is pretty high, Make sure to get high static pressure fans for it.conclusion:Great performer, would be nice if it had a few more ports for routing options. Overall this is a good rad for my setup.

I purchased three Thermaltake Pacific CL420 64mm thick copper radiators January 15th, 2020. The serial numbers on the radiator boxes were CL-W193-CU00BL-ALS000266, CL-W193-CU00BL-ALS000267 and CL-W193-CU00BL-ALS000276. They were manufactured within 10 radiators of each other.Heavy soldering was completely blocking the copper chamber ends on approximately 1/3 (16 out of 48) of all chamber ends seen from inside the brass end tanks looking through the G1/4 ports. This solder prevented liquid from flowing through the copper chambers (the channels that allow liquid to flow from one side of the radiator the the other). The center row of chambers seemed to be the chambers that were most likely to be completely blocked, where as, the chamber rows above and below were more likely to be either partially blocked or unrestricted.Additionally, one of three radiator's paint flaked off in big chunks from the edge corners of the brass end tanks simply handling it. If I had to guess, the copper and stainless steel surfaces were not prepared properly prior to paint application during manufacturing.I have used Alphacool, XPSC, and EK radiators in the past and did not have either of these issues.You MUST inspect the chamber ends within the brass end tanks for solder blocking them. If you don't, you run the risk of unknown decreased thermal cooling performance, and decreased flow rate causing unnecessary motor stain on your pump.

Great radiator for the money. Lots of surface areas to dissipate heat. With the opening at the top the radiator can be filled like a reservoir thus eliminating the need for a separate reservoir system.

It was easy to use this radiator especially because flow direction doesn't matter.I recommend you change the plastic stop fittings though. I was doing leak testing and they were the only thing leaking in my system.
