Alphacool today presents the brass variants of the Eisblock Aurora XPX Pro and XPX Edge CPU coolers. Due to the high popularity of these very powerful CPU coolers, Alphacool has decided to offer these additional variants in black and chrome.

The new XPX Aurora Pro and XPX Aurora Edge models are made entirely of brass and are specially designed for processors with particularly large processor cores. In combination with the nickel-plated copper base, the waste heat of the CPU is distributed even better and transferred more efficiently to the cooling liquid. This is further supported by Alphacool's Subzero Thermal Grease, which is included with the coolers. With 16 W/mK, Subzero is currently one of the most powerful thermal pastes on the market.



The high weight and perfect color coating leave no doubt about the high value of these CPU water coolers. The matte finish gives them a noble appearance. Behind the Alphacool logo, two digital aRGB LEDs are installed, which create a unique illumination. Both of these features make Alphacool's XPX Aurora Pro and XPX Aurora Edge brass coolers particularly interesting for users who prefer a discreet appearance and do not want to use extensive aRGB lighting.

Features
  • Material cooler base: nickle-plated copper
  • Material cooler housing & top cover: brass
  • Illumination: 2 digital aRGB LEDs
  • Threads: 2x G1/4"
  • including Alphacool Subzero 16 W/mK thermal grease
Compatibility:
1. Eisblock XPX Aurora Edge
  • Intel: LGA 115x / 1200 / 1700 / 2066
  • AMD: AM2 / AM2+ / AM3 / AM3+ / FM1 / FM2 / FM2+ / AM4 / AM5
2. Eisblock XPX Pro Aurora
  • Intel: LGA 115x / 1200 / 1700 / 2011-3 / 2066 / LGA 3647 / LGA 4189
  • AMD: TR4 / TRX40 / sWRX8 / SP3 / AM4 / AM5

I understand the value would be limited, but why arnt there ever benchmarks included of this waterblock vs others?
Or is it because they know they are just releasing "new" products to be new, to receive some mindshare again, without actually improving much?
I mean you can be sure some inhouse testing has been done, why not share that?

These coolers are only a brass varinate of the normal XPX and XPX Pro which have been on sale for some time. The differences in performance are small and rather in the range of measurement inaccuracy. It is more about optics and design.
And honestly, who believes a manufacturer's performance data? Even if it's against their own products?

How does brass compare to pure copper in terms of thermal conductivity?

Only the housing is made by brass intead of acetal. The cooler bottom is the same, nickle plated copper.

It's less for brass since it's an alloy of copper and zinc. Copper has ~4X the thermal conductivity of zinc. (depending in the composition of the alloy).

Ah, I see. Thanks to both of you!

I'm a bit sceptic for plastics, so brass/metal tops are better suited to my needs. Always nice to have a choice, though.

Edit: now looking at the title, it could definitely be phrased better, @EddyAlphacool
'Made entirely of brass' - you can understand my confusion.

Well thats why I started with the data being of limited value.
But just a general idea of performance vs competition seems a logical thing to include imo.

Techpowerup requested today if they can have samples for their next roundup. Then you get independent data instead of data from us.

Now I'd love to see an Eisbaer with similar minimalist, metal design. Metal housing for the pump and cooling array at the base, and the reservoir top remains in plastic (for a bit of weight-saving) but with a steel or aluminum exterior cover. Or go further with a full brass reservoir on top, and G-1/4 outlets out the sides instead of the top, similar to the new EK pump-block combo revealed today. Basically to allow for a cleaner top-down profile while still clearing most RAM sticks or VRM heatsinks thanks to the tall height of the Eisbaer.

Do you believe in brand's benchmarks? Yeah, me neither.

do I have to repeat myself again?
"I understand the value would be limited"
"Well thats why I started with the data being of limited value."

Benchmark Scores My system matches standard results. I use benchmarks to set fan curves; I don't care about scores.
I understand the value would be limited, but why arnt there ever benchmarks included of this waterblock vs others?
Or is it because they know they are just releasing "new" products to be new, to receive some mindshare again, without actually improving much?

Testing wouldn't be practical since a lot of the thermal performance is tied to other parts of the loop: tubing, fittings, reservoir, pump, radiator, fans, coolant, whatever. It would have to be an extremely rigid test environment to ensure all the other variables remain constant. And it takes more time to properly fill a loop and work out the air. It's not like testing tower coolers or AIO coolers where you clamp on the device, plug in a cable or two into a fan header and off you go.

And what if a competitor's products fare better? Does Alphacool admit that Dodgy Bros. OMG-420 CPU waterblock is 0.3 °C cooler and is 15€ cheaper?

Does anyone believe Apple's claims of Apple Silicon's superiority over an unnamed competitor's product?

Eddy's right, this is not a useful exercise.

The most believable statement a manufacturer can make is that the new product is an improvement over its predecessor: thermal performance, size, weight, aesthetics, price, environmental friendliness, etc.

This isn't specific to PC hardware. Can a pizzeria claim theirs are better than the pizzeria a block away without sounding completely arrogant? Or a company that makes knitting yarn? All purpose flour? Trash can liners?
