Alphacool Eisbaer 420 Liquid CPU Cooler Pictured

[btarunr]

Here are some of the first pictures of Alphacool Eisbaer 420, a closed-loop AIO liquid CPU cooler by one of the few manufacturers that doesn't sell re-branded Asetek wares. The cooler is designed for extreme overclocked setups using HEDT processors, and supports upcoming HEDT sockets. The cooler consists of a copper-base pump-block plumbed to a 420 mm x 140 mm full-copper radiator, with three 140 mm fans. One of the coolant tubes has a quick-disconnect fitting.

Random, casual user's lament:

Try and compare this to top dogs of the casual market such as Corsair's 115i. Nope.
i) most sites literally steal other sites' information tables, use them to post comparisons as if they've actually done the work themselves. You google enough, it's more than evident.
ii) because of the above -and- the half-assed job most sites do, the tables of comparison one finds are usually outdated, in the sense of their not including the latest models from other companies and/or useless as often enough the frame of comparison is schewed or incomplete (comparing 'x' model's default fan curve with 'z' model's top RPM curve, different CPUs tested with each model, etc...)
iii) profit? Nada, zilch, nicht. Wait until the model is old, or pay now and pray.

And that's being kind, as we occasionally (lol, make that almost always) have to deal with the bias/hype. Won't get into that though, no point. So much knowledge and time, gone to waste because.. humans.
This also makes one want to comment on the joys of the cheap Internet and everyone's "having a voice" only to the detriment of everyone else's, but that too is pointless. Again humans.

But to leave all that aside as no one gives a damn, isn't this radiator a bit too thin for a push/pull config?

why would a 27mm radiator be not suitable for push/pull config? there are other single radiator solutions with two fans being sold. i have different question: it is successor to Eisbaer?

 

[Caring1]

I'm not a fan of the hoses sticking straight out from the pump top, it would be better from the sides to allow fitting in smaller cases without looking cramped.
It just looks messy.

There is a reason i did not use the word suitable, as that would entail what they're selling is unsuitable, ergo faulty.
What i did wonder was whether and i quote, that rad was "a bit too thin" for a push-pull config. Thinner rads, due to fins per inch, usually don't benefit much from push-pull and/or benefit to such a small extent that it's not worth the extra cost.
I hope that helps.

there are other single radiator solutions with two fans being sold

Is that an argument for what is right or wrong, beneficial or excessive? Really..?
Some sell RGB lightzzzz and disco effects. Some sell according to looks and style rather than performance; look at Caring's post, no clue if it's a better cooler than others, their only comment was in regard to its 'looking messy' (why should anyone care if something hidden inside a case looks messy? Since when should that be a deterrent to purchasing). See my point?

FYI, the current description is for the Eiswand. This Eisbaer has a single set of fans only, I have let them know.

That said, thin rads is not necessarily an indication of anything. Push-pull helps most with high airflow restriction radiators no matter the thickness of the core- you can have high FPI fins, thick fins, louvered fins, short fins in multiple rows and so on.

 

[huguberhart]

There is ..

yes. i didn't know, because i have no experience in water cooling yet. however, i'm interested in that Eisbaer for my next build (even if in my dreams - money ) and i try to learn. didn't mean to sound condescending..

 

[Aenra]

..

Before we take this to the moon and back for a simple damn question.. why reply when you don't have an answer, lol?
Or if you do have an answer, why not come back and state it clearly? Say that 'x' rad used in this 'z' config is of 'i' FPI, ergo yes, it matters, or no, you're right and it's superfluous.

Why the nerdy theoretical merry go round..? Just act normal.

@huguberhart it's why i thanked your first post, before replying, so you'd know i'm all good either way. No worries

The question itself was ambiguous since all you mentioned was the radiator thickness, and I provided some more context to it. If you want specific answers, ask specific questions

...

Don't do this, we're just gonna derail it even more. I did ask a very specific question. You went all encyclopedia Britannica on us, but failed to actually provide one (a reply that is).
If it's hard, let me repeat it, so you can judge for yourself how specific i was or i wasn't.

I asked if a push-pull config is necessary in this specific cooler given this specific cooler's radiator's thickness.
This cooler.
This rad.
This fan config.
Is it too much or not?

What more do you need? A diagram?

Ah, I assumed you read my earlier post. The description is currently incorrect, as this particular AIO cooler only comes with one set of fans. That description is for an external cooler which has a 45 mm thick radiator with a very different core design.

But to answer your question- the specific radiator used here is the Alphacool NexXxos ST30 360. The radiator core has a single row of 12 coolant tubes that are 2.1 mm thick on average, and a single fin stack that comprises of 45-50 micron thick copper, louvered fins at ~18-19 FPI, and are serpentine in design. It is ever so slightly higher than average in airflow restriction, and I have actually tested the 480 mm version of the same radiator with fans in push-pull. Assuming the fans are not a factor (some fans do not do as well in push-pull as others, even on the same radiator), this does scale fairly well with airflow and push-pull will give you a good bump in heat dissipation at similar or even lower noise levels compared to push or pull alone. Hope this helps!

@VSG awesome

@VSG If you don't mind the follow up; do you have any impressions you want to share about Alphacool's fans?

The fans in that picture are new to the Eisbaer lineup, so I can't say how they perform. The previous models used the Eiswind which was a lot more noise optimized at the expense of static pressure and airflow performance through that very radiator, and reviewers in general did not like it as much even though I was a fan (heh) of it. So I assume these ones either have a higher max RPM or are more performance optimized.

The current best retail fans for radiators from Alphacool are their Susurro which are pretty good. One potential quirk with those fans is they come with a rubber shroud (removable) that goes all around the frame and the resulting fan thickness is such that you will not be able to install a middle fan between two others with the usual 15 mm fan hole spacing. They did say they would be addressing this, but I am not sure if the current batch has the fix implemented or not.

@VSG misunderstood you. Please post more often.

Thank you

*Eisbaer
Interestingly, that means it has 3 x 140mm fans per side, which will restrict it's placement in a case even further unless it allows radiators over 360 to be used.

 

[EddyAlphacool]

Out of the box, it has 3x 140mm fans.
