EKWB has introduced its third-generation water block for AMD’s Ryzen Threadripper processors. The new EK-Velocity sTR4 uses EKWB’s latest advances in cold-plate design and therefore promises somewhat better performance when compared to predecessors. Following the latest trends, some of the new water blocks for AMD’s Socket TR4 CPUs feature controllable RGB lighting.

The new EK-Velocity sTR4 water blocks feature a redesigned cold-plate that covers the entire surface of the IHS of AMD’s Ryzen Threadripper processor. The new cold-plate features 91 micro fins that span across all dies within AMD’s CPU, thus ensuring proper cooling for each of them at all times even when certain cores work in Turbo mode. Traditionally for EKWB, the cold-plate is made of ‘purest copper available on the market’ that is nickel electroplated and polished to a degree that it can be used as a mirror.

EKWB will offer six versions of its EK-Velocity sTR4 water blocks with tops made of CNC-machined POM Acetal, acrylic glass or nickel-plated brass. In addition to regular water blocks, EKWB will offer models with RGB lighting (can be controlled using software from leading makers of motherboards) featuring tops made of POM Acetal or acrylic glass.

The new EK-Velocity sTR4 come comes with a pre-assembled mounting mechanism that is installed directly onto the Socket TR4 (or Socket SP3) mounting holes. The water blocks use standard G ¼ inch barbs for tubing and therefore are compatible with an extensive range of custom liquid cooling systems.

EKWB’s EK-Velocity sTR4 products are already available directly from the manufacturer and shortly will be sold by its partners. Depending on the version, the water blocks cost from €99.90 to €129.90.

    ... I really don't get the point of (all of these) coolers for CPUs. Back in 2004-2007 when I used watercooling, this trend with special conical channels and nozzles and stuff started and even then it wasn't clear what the actual benefit was. I'd rather have a simple cooler with extra fins to dissipate a bit more heat (typically you'll have a fan somewhere to cool chipsets/RAM/whatnot), but I'm not aware of anything like that

    While I'm no cooling expert, water has many advantages that air coolers don't.

    Water can dissipate heat faster by bringing the heat away from the CPU really fast. Water absorbs heat better than air, and takes longer to heat soak than air does. and a water cooling's performance is dictated by the radiators, which one can fit as many as they want. Plus, the added bonus for me was the noise. While yes, I have 4 fans and a pump, I can have each spin at 1000RPM, which is practically silent at idle. Fans only ramp up to 1500RPM on 100% CPU load, which even then, is hardly audible. Plus, Watercooling just plain looks amazing.

    Downsides of water cooling is maintenance. It's not as easy to maintain than a good air cooler.

    And in the 10+ years since you did watercooling, manufacturing and R&D have improved for them. Give it a shot again. It's fun and well worth it if you like that sort of stuff!

    When is EK going to listen to customers? People have been complaining for years now that their in-out port design at mid-block allows bubbles to form in the heatsink because their out port is halfway down the block. Even a closed loop with good design can generate a water vapor bubble that can shutdown flow.

    Their 2 year old monoblocks are designed better with the out port at the top edge of the heatsink so any bubble get sucked through the line and dissipated into the reservoir.

    I just don't get why EK has been ignoring customer feedback on this. This port design is prone to bubble formation and people have been telling them that for years now.
