Bykski GPU Waterblock Water Cooler Copper GPU Liquid Cooling Block Liquid Cooler Graphic Cards GPU Block Backplate for Gigabyte Radeon RX 6800 XT Gaming OC (12V 4-Pin RGB LED Lights)

They emailed me and confirmed I had the right card. (I do appreciate that.) Once confirmed, sent the card from China. I expected it to take 3-6 weeks to come from China, but I was pleasantly surprised to have it in my hand 10 days later. Even better, unlike their competitors, they included a backplate, fittings, and extra thermal pads and screws. (I appreciate that even more, as I lost one screw and one thermal pad got squished into uselessness when I stepped on it while trying to find the screw I dropped.)It cools fabulously, much more stable and cooler than the air cooler at a nice, cool 49C/61C peak while mining, while overclocked by 350MHz. (I mine with it part time when not actively using the system, and decided to test with mining first. While mining on air, it was sitting at 80C/85C with no overclock.) The EKWB block on my 980 Ti wasn't even that cool. I hadn't heard of Bykski before, but now that I have, I'm impressed with them. Considering this is the only waterblock for this model (Gigabyte RX 6800XT Gaming OC) I didn't have a choice which block to go with, but I'm not regretting it at this point. This block is good.I haven't hooked it into the RGB yet. I'm not real big on RGB in any case. The added remote RGB controller seems very nice.

This block was part of my first custom water cooling loop. I've never felt I've really needed to turn to water before this card but I'm glad I did. Stock temperatures on this gigabyte card were pretty bad even in a case with great airflow. Undervolted at 1040mv left me with low 70s edge and mid 90s junction temps which I thought was pretty awful especially undervolted with fans approaching liftoff at 100% and pulling about 40 watts less than stock. Pretty poor cooling from Gigabyte.Now onto the block. Very nice looking product but the performance is amazing. From 73/95 Celsius to 40/52c in a 78f room. The VRM and VRAM run warmer than the junction but are still very cool in the high 50s. Even with an overclock to 2545mhz at 1.15 volts, it stays about 48/65c.ProsTemps, nice led lighting, looks and fits great ***ConsCame with instructions for a CPU block but it's pretty self explanatory especially if you've messed with GPU heatsinks beforeBlock hangs too low for the PCI slot latch to lock onto the PCB but it's still not going anywhereIf you're like me and settled for a less desirable 6800xt model and are looking for a block, this block gets the job done and I am pleased with my purchase.

So I ordered this a month ago or so and end up it was only for the 6800 XT. Contacted the seller to explain problem I got a swift and great answer end up they care about customer satisfaction and sent me a new model straight out of factory it wasn't even manufactured yet for the 6900 XT.OverallCustomer care:15/10Cooling: 10/10 as expectedLLooks: 20/10 the you can see the PCB thought unlike corsair amazingRGB : 1/ 10 very weak led for my opac liquid unless I'm doing it wrong.
