Alphacool presents today the Core XP³ Brass CPU cooler. Due to the still high popularity of the very compact Core XP³ CPU cooler, Alphacool has decided to offer another variant. The Core XP³ Brass is, as the name suggests, made of brass. Together with the nickel-plated copper base, the waste heat from the CPU is even better distributed and more efficiently transferred to the coolant.

The high weight and perfect color coating leave no doubt about the high value of this CPU water cooler. With this full metal cooler you get a very compact CPU water block for all current mainstream sockets from AMD and Intel. It offers the typical high Alphacool quality paired with outstanding performance at a fantastic price.



For more information and to purchase, visit this page. MSRP: 44.98€ including taxes.

With all of the shortages it doesn't surprise me that they've gone to brass. I'm sure copper is getting hard to source at any kind of half way decent price. If it performs well, it will sell well at that price, IF they can keep it in stock!

The base plate is still copper, they just changed the acetal for brass (and raised the price by 5 euros)

Those who have made reasonable contracts also do not suffer from a shortage of resources. We have no problems buying copper and other metals because we have long-term purchase agreements with suppliers. Only companies that think in the short term have problems because the suppliers don't want to do that anymore. Prices have risen, but there is no shortage, except for a self-generated and artificially created shortage.

@Crackong
Yes, you can choose any orrentation you want, also with all our XPX (non Pro) cooler on every compatible socket.

With AM5 launching next month I'm curious why there's no support for it.

@EddyAlphacool Can you explain why brass is a better choice than Acetal or Copper for the top? FWIW I've been very happy with my Alphacool radiators but haven't used their blocks or pumps yet.

@ymdhis
That is correct. Since I live in Germany, I know the problems. But the bottlenecks in all areas are all, without exception, self-inflicted because people think too short-term when planning. It is pure stupidity because people want to haggle over every cent. The fact is, all problems of this kind are self-inflicted. We plan completely differently here and buy everything in stock for at least 12 months and make long-term contracts with the suppliers. That costs us a little more in the end, but it gives us planning security.

@Blaylock
We will say something about AM5 later. In general, it will be no problem to switch to AM5 with all coolers from us that have a bracket for AM4.

Honestly.... Brass doesn't really do anything better than acetal. It's better in feel, the weight makes it feel better, and some believe that a brass top makes for better heat distribution and therefore better heat absorption. But the latter is actually wrong. According to our measurements, brass tops do not provide any temperature advantages. Many still want a brass version because it simply feels better and is not "plastic". If you don't care, you can simply take the acetal version. There are definitely no disadvantages. (Unless you want to believe in it compulsively :D :cool: )

Hi,
Acetal is basically cheapest material there is but if you like black it's the cheap way to get that look.

Brass like copper, brass being the harder material is great for bodies of blocks seeing copper is softer so it's great for cold plates.
But brass like copper are great at transferring heat/ cold or at being heatsinks similar to aluminum but aluminum is supposed to be better but not good for water loops.

Plastic is not a good heatsink so enter acetal.

Personally I'd opt for an acrylic body at least you can see the inner working and if it ever gets clogged you can tell :cool:

@EddyAlphacool

Have you considered versions with shifted jet point? After experimenting with cuplex kryos NEXT it really does improve die temps.

@Ferrum Master
Yes we did, but I can't tell you much about that right now because I don't have the results in my head right now. It always depends on the CPU and the DIE how much this affects.

@ThrashZone
The material cost between acetal and brass/copper is not so much the big deciding point. They are higher, but the significantly higher cost of brass/copper comes more from the fact that the processing of the materials is more expensive and more complex than acetal.

I get what you're trying to say but I believe you might be slightly off. The reason copper makes a great cold plate has nothing to do with its hardness but has everything to do with its thermal conductivity. Brass is actually not a good conductor of heat at only 96 Wm/K, slightly higher than Iron. But that's not the point. The Water block top is not responsible for thermal conduction, that's what the cold plate is for. This is why the top can be made of Acetal, Acrylic, Brass in this case, or any material that is not going to react negatively with the copper cold plate or coolant used.

@Blaylock
I wasn't concerned with the cooler bottom, just the cooler housing. It does not matter whether it is made of brass, copper or acetal. Which material is used here has no influence on the cooling performance.
The cooler base is made of copper or nickel-plated copper, which is all we use for DIY end customer products.
Some people just believe that the choice of material in the case makes a difference in cooling performance. And that is not correct. That's what I was trying to get at.

@DeathtoGnomes
I haven't decided yet when we will release information about it. Either the end of this month or the beginning of next month. Timing is important here, so people don't forget about it right away.

Correct. That's exactly what I was trying to explain to ThrashZone.

That's great news that it may be AM5 compatible. Thanks Eddy.

Cooling performance of the Acetal version is only approximately 2°C behind the performance of the brass version
I'm more concerned about damaging using brass fittings with acetal. Durability.

Hi,
Nope copper has flexibly to be designed to flex to weird cpu shapes and bend easily with a little pressure.

If that is really what you think about metal then why do manufactures usually make heatsinks out of it rather than plastic
Most people know plastic is not a good heatsink whether it's water block or air cooler for cpu/ vrm/ pch/ m.2 makes no different all that is needed is good air flow so that makes metal a far superior heatsink even on a water block.

Acetal is an extremely hard material. If you destroy an acetal thread with brass connections, then you are fundamentally doing something completely wrong. The force required to accomplish this would be enormous.

Hi,
You kind of contradict yourself here
Brass is a hard product or at least a lot harder than acetal
Acetal is soft material
Otherwise milling would be no different but fact is they are very different products
Acetal is very easy to scratch even with a finger nail try that with brass or copper not easy.

I've polished both acetal and brass for the record because ek acetal you can see milling marks on it "I have some images before and after polishing not on this machine though" so I do know how hard both are and acetal sands so easily it's so odd you say it's a hard product
Here's the image
Acetal polished cookie.png


So you guys must do something to your acetal to make it hard is all I can say and if so what process makes it hard as brass ?
I will add your acetal looks light years smoother than ek's :D

Prime example
Use simple easy to get woodworking router bit
Acetal would be as easy as butter with one
Brass it would be destroyed as soon as it hits it.

Nope copper has flexibly to be designed to flex to weird cpu shapes and bend easily with a little pressure.

If that is really what you think about metal then why do manufactures usually make heatsinks out of it rather than plastic
Most people know plastic is not a good heatsink whether it's water block or air cooler for cpu/ vrm/ pch/ m.2 makes no different all that is needed is good air flow so that makes metal a far superior heatsink even on a water block.
I'm not suggesting any heatsink is made of plastic. Plastic is a horrible conductor of heat. Re-read my posts. I think what you're missing is this water block is made of a Copper cold plate (the part responsible for heat transfer) and a Brass top (this part just allows fittings to be mounted and helps channel the water over the cold plate along with the jet plane). The top has nothing to do with its thermal performance which is why most companies will use Acetal or acrylic also.

Much better than all the gimmick products from EK lately...

Yeah i don't know about that ... got an EK Quantum Velocity full nickel block yesterday for 33 eur , acetal/plexi variant was going for 23 eur ( summer sale ). EK still offers great value you just need to buy smart .
