Today we are going to round two with the EK Quantum Vector2 FE RTX 4090 D-RGB. A GeForce RTX 4090 FE is per se well cooled and the original cooler is actually also perfectly sufficient. So one would hardly have a valid reason as a buyer to disassemble and rebuild this collectible. Well, almost none, because the weight and space requirements of this card are the other side of the coin, although the board itself turns out to be quite small. Exactly at this point, however, such a card becomes really interesting for the water cooling fraction, especially since it is one of the somewhat cheaper specimens of this high-end family (assuming a bit of luck).
This is where the second tested water block comes into play in the form of the EK Quantum Vector2 FE RTX 4090 D-RGB (so there will be more follow-ups), which comes with self-confident prices starting at around 239 Euros, which is unfortunately also on par with Corsair. That’s really not little and you have to be tough when you provide the already very expensive card with such a topping as a conversion. We will see later today that this is definitely worthwhile, for the customer as well, of course. There is a three-year warranty anyway.
Scope of delivery and accessories
Let’s unpack the cooling block first and see what EK supplies us with. You get the water block including acetate cover and light alloy backplate, along with the terminal already screwed in place and the integrated ARGB LED light bar, plus a few other things. The very stable and torsion-resistant single-slot bracket and the replacement O-rings for the terminal are very positive. However, the pads are rather lower shelf and would certainly have deserved an upgrade at some point.
Other loose parts include a pack of screws and washers, two dummy plugs, two different sized Allen tools for screwing in the different screws, and a universal tool for loosening cables and connectors. An adapter for the connection to the digital ARGB of the motherboard is not needed, because EK uses a normal Preci dip header and thus 5V D-RGB. Unfortunately, you will not find a printed manual; you have to download a PDF file via QR code.
Unboxing and key data
The block turns out to be quite timeless because the acetate is soothing to the eyes. EK has installed a light strip with 34 D-RGB LEDs so that the cooler does not mutate into a black hole. The connection cable is a sufficient 50 cm long and not proprietary (see above)- Visually and haptically, this is all perfectly fine and the hexagon socket screws complete the picture of a solid implementation.
Although the PCB is short by design, the water block mounted on the PCB together with the slot bracket and overhang (cover) measures 23.63 cm in length again. The water block’s height of around 14.8 cm including the terminal is still moderate and customary for the class. The thickness including the backplate is around 2.7 cm. As for the copper block itself, EK says it should be the usual 11-gauge, nickel-plated electrolytic copper. The cover is again made of acetal, i.e. POM.
You have to do more with the assembly than you do with Corsair’s cooler, but I’ll get to that in a minute. At least the threaded sleeves of the spacers are already firmly mounted. The fact that you can see the machining marks of the tools very clearly is visually rather unattractive, but there is sufficient evenness on the relevant surfaces where paste is later applied or the pads rest. Only the recesses (e.g. coils) show the development during removal.
The backplate, on the other hand, is more of a purely optical nature and also serves as stabilization. The supply line to the RGB stripe is long enough to be connected to the RGB header of large mainboards. Otherwise, the plug fits without adapter. How the whole thing can be assembled now, you will see after the next page. First of all, the manual without QR code as a service for the curious. The full marketing salvo is available, as is the product, on the EK homepage in the store.
