Phanteks Cpu Water Block Acrylic Cover RGB Led Ph-C399A_Bk01

A CPU block thats is build with quality, highly recommended

Acrylic on this is the thickest I've ever seen on any water block. It's also polished, which is nice. It gives it the appearance of one solid block of cast acrylic. RGB (not addressable) is subtle. If you are using anything other than a clear or translucent coolant, the RGB lighting is near useless. Otherwise, pretty good.PROBLEM: Do NOT tighten the screws all the way down. This will put uneven pressure on the CPU's IHS. This will cause odd temp spikes. Tighten the screws down enough such that the spring pressure is what is putting force on the block. Again, DO NOT TIGHTEN SCREWS ALL THE WAY DOWN. You will thank me later.

It's beautifully crafted, and a nice touch is the magnetic bits to adjust the name. it is very high-quality craftsmanship, and with my set-up of 96cm's woth of radiators and a DDC pump at low rpm (so slow you can watch the find go round and round the flow meter), it keeps my 2990wx at a cool very cool 35c idle temp at 20% overclock. flow is nice and even inside as can be seen if there are little air bubbles during first fill.. i actually have one on the TR-4 and one on the 9900k inside the same corsair 1000d case.17,000$ computer i paid 13,000$ for all the kit.. i wanted it protected by quality, and luckily, that's exactly what this beauty is.. Top Shelf product. with a pretty lovely look when it glows.

The build quality is great—I’ve used Phanteks water locks on intel cpus, and those were good enough for me to try this model for an AMD threadripper pro. Unfortunately, I could not get the waterblock to reliably mount on the cpu and socket with the “universal” mounting screw setup of the waterblock. The mount is such that each of the four mounting screws can slide into one of two positions so the waterblock can be rotated 180 degrees depending on how the user wants to mount the waterblock. Unfortunately, the mounting screws keep getting skewed and were difficult to align to the mounting sockets on the motherboard. I tried two different waterblocks of the same model, so it’s a design flaw and not a one-off defect. I returned this to order a different brand waterblock for my threadripper pro.

I'm building my ultimate white, chrome, and ice blue system. Zenith Exteme Alpha, 128gb G.Skill Trident Z Royal silver, Asus strix 3080ti white edition gpu, AMD Ryzen Threadripper 3070, Asus 850watt pcu,white,...etc, etc, etc. This piece of carefully crated art compliments my rig perfectly!If you're on the fence about getting this cpu cooler..., don't sleep! Get it!
