Bykski CPU-RYZEN-X-MK CPU Water Cooling Block - Clear w/RBW (AM2 / AM3 / AM4 / TR4)

So I wanted a water block for my custom loop that would be able to do AM4 and TR4 (as a possible future upgrade) and only a few that will do both.Even fewer will do both and not cost a whole bunch of money AND perform well. Bykski seems to make all them as far as I know. And the build quality and performance are, if not exactly top notch, are close enough to it not to matter. Typically in reviews its a ~1C difference vs a dedicated higher end AM4 or TR4 block.Other things like radiator size, fans, or TIM application will all make a far bigger difference in temps than going and spending more one of the more expensive blocks.As far as appearance goes beauty is in the eye of the beholder but I can tell you there aren't any burrs or scratches on the metal or acrylics and the fit and finish look great. Only thing I wish, and why I didn't give it quite 5 stars, is that the wiring for the RGB LEDS isn't detachable (well that and technically it doesn't quiiiiite perform as well as the very best AM4/TR4 blocks). But that is a personal aesthetic sort of thing and it didn't stop me from buying it at all. I'll learn to live with it.Current system:AMD 3900X @ ~4.3Ghz (all core peak, 1.32v, my 24/7 OC, too many volts needed for much higher all core, 1x die will get to ~4.5Ghz at 1.38v)X570 Aorus Master (BIOS f5g AGESA 1.0.0.3AB)32GB DDR4 3000 (DOCP for now, 2x 16GB sticks)2x m.2 SSD's, 2x hard drivesNvidia 1080 on its own water loop (AIO)My CPU water loop is a 56mm thick 4x 120mm rad with push+pull fans @ ~1000rpm, a D5 pump/res combo, and this waterblock. Ambient temps in my PC room are ~22-25C throughout the day and fully loaded in actual applications (Prime95 can get it to spike around ~78C) the CPU stays around ~69-72C which is good for this CPU. Idle is typically within 10C of ambient or less. In gaming it tends to run around ~50-54C or less. Actual water temps read much lower, ~30-38C typically, measured with a probe screwed on the radiator.Noise is minimal. The mechanical hard drives seem louder than the loop but I don't have a good dB meter to test. I'm very happy with the block and loop and I think it'll be the one I use for a long time.

Got this waterblock installed on my Ryzen 7 2700X. It looks great in my opinion, but it is rather large on an AM4 motherboard. My M.2 drive just barely fits as the RGB cable for the Block hangs out of the "Exclusionary Zone" of the CPU.Performance: This block does not perform nearly as well as the EK Monoblock I was previously running. With the old block my 2700x NEVER got over 51C under heavy load. With this Byski block (just cooling the CPU and not VRM) I get up around 60-65C. Note: I did change from a X370 Motherboard to a X570 board, so the voltage characteristics and boost frequencies may be different.Overall I am happy with this block. I bought it for the looks and for the possibility of going to a ThreadRipper CPU later with the same block. However after seeing the performance with just my Ryzen 7 2700x, I'm not sure I would trust this block on a ThreadRipper. I will likely just get a 3900x or 3950x instead and stay with AM4.

Update 1,After running some stress tests (Intel burn test) the block keeps my cpu (3900x) at around 65c.Previous bitspower block was at 75 to 80c.That’s a drastic improvement.While gaming in division 2 Cpu is at 55 to 58cWith fans @ 600rpm.Previous was 65 to 70cAgain another great result.Increased to 5 star. Definitely worth it.Seems like a good quality block. The Inlet fins seem to be positioned directly over the 3900x’sCCD’s. Should perform very well. I will post an update once I have it all running. I am using the X570 Aorus Master and the only fitment issue is the top m.2 slot’s heatsink. I had to use a lower profile heatsink instead of the original as the blockPartiality overhangs by about 2mm.Bykski does mention the incompatibility with the Auros Extreme however they should also add the Master and most likely the ultra to that list as well.Bykski and Barrow are turning out to be great alternatives to the other well known brands.My system specsX570 Aorus MasterR9 3900x64 GB Tridend z 3600 16-19-19RTX 2080ti

Its a great looking block. My knocks for it is the size(nearly takes up the entire cpu area) and the aluminum screws. I worry about whether with the amount of force needed to apply pressure on the plate to the cpu will hold up over the long term. Other than those quibbles the block looks great and appears to cool great.

So far so good on block performance.Ryzen 3900x , 270 photon res/d5 pump, 360 gts radiator. Temps don’t go above 50c. They idle around 38c.Rgb sucks... it keeps shorting and flickering. I’ve tried all my rgb headers. It’s the rgb strips inside the block. If you touch the wire sleeve it starts acting erratically.

It's mint. Works great and looks amazing.
