About this part
This full coverage block directly cools the video cards core (GPU), graphics memory (RAM), and voltage regulator modules (VRM). By directly cooling these components, you can achieve great temperatures along with the ability to reach higher overclocks or extend the overall lifespan of your card by running at below factory temps.
The block is constructed of high-purity copper that is nickel electroplated to prevent oxidation. A high-flow design is used to allow multiple blocks to run in series. Top and bottom ports can be used to configure parallel or serial designs in multi-block setups.

Customer Reviews
I purchased this product with excitement. Although, I've never heard of this company before. But since they offered this water block for my ZOTAC 4080, I decided to give them a shot. And let me add that this company ships out products very fast if you purchase early the same day, they will ship it out same day. And when you receive it, You will be pleased at the packaging. Not to mention you get 2 free Sour Patches. Yes, I did say Sour Patches (The Candy). Anyway, I am super pleased with the product. Easy installation. The In-N-Out holes, are embedded onto the plexiglass. I am super pleased with this company and I will purchase from them again. So far I've purchased this GPU Water Block, I've also purchased a CPU Water Block, and 2x 360mm Radiators all BYKSKI. If you know what you doing, You will be content with this product and company. Sadly, there are not that much reviews of this company out there on YouTube. BYKSKI, if you're reading this hook a brother up with some products I'll definitely start a YouTube to review them. :)
It would be very easy to get the rating to 5 stars by including the RIGHT instructions with the water block. Mine arrived with instructions for a motherboard. The QR Code sent me to a Chinese version of the website that did not even show the 30 or 40 series water blocks. So yeah, had to go online and search youtube for videos on where to put the thermal pads and get everything properly assembled. The other thing that needs to be addressed is better markings on IN/OUT ports.. They do it in WHITE and it is very had to see when surrounded by clear. I had to re-arrange half the tubes in my loop because of that poor marking. It probably would have been stated in the PAPER IINSTRUCTIONS had I gotten the right instructions to begin with.
Other than that, it is working amazingly well. This being my first hard line water cooled build, I have had NO leaks of any kind from the water block. The RGB lights up amazingly well, and it works great at keeping temps well under control.
