Testing Results, Maximum Fan Speed (12 Volts)
The thermal performance of the Alphacool Eisbaer 240 in relation to its noise level output is impressive. With an average thermal resistance of 0.078 °C/W, the Eisbaer 240 does perform about on par with other similarly sized AIO liquid cooling solutions, falling only slightly behind the Corsair H100i and NZXT Kraken X60, and overtaking the Reserator 3 Max Dual and SilverStone Tundra TD02 (first version).
| Core Temperature, Constant Thermal Load (Max Fan Speed) |
Even though the thermal performance of the Eisbaer 240 is very close to that of these coolers, there is a world of difference in terms of acoustics. The sound pressure level emanating from the Eisbaer with its fans running at maximum speed is the lowest that we have recorded from a dual 120 mm fan AIO liquid cooler up to this date and many dB(A) lower than that of nearly every competitive product. The EKWB EK-XLC Predator 240 is the only dual 120 mm solution that offers slightly better thermal performance at the expense of some additional noise, while the dual 140 mm Corsair H110 offers about the same overall performance but with a 280 mm radiator and larger fans.

This idea just doesn't die.Quieter and cooler and cheaper than a Noctua NH-U14S.

He should have said best noise/thermal performance for 240mm radiators. Because larger radiator and larger fans will always win in this metric. (H110 is a 280mm)BrokenCrayons - Monday, August 1, 2016 - link
Pass on the water cooling. I don't like the idea of mixing liquid and electricity for no tangible benefit over the HSF that was included in the box. Yes, sure the temperature of the processor is lower, but who cares really? As long as it's not above the manufacturer's spec, temperature makes literally no difference to me. I can understand wanting to cut back on noise and that might warrant an upgraded air cooler over the retail boxed one, but even then, a lot of the reasoning behind that ignores ambient noise of HVAC, other people, and blaring televisions which would drown out the relatively small amount of noise from a stock cooler.ikjadoon - Tuesday, August 2, 2016 - link
Why are you even reading this review? LOL. It's like a guy who drives a Camry walking into an aftermarket parts store: "A turbocharger? I don't like the idea of mixing more air. Sure, the horsepower is higher, but who cares really?"Wrong review and maybe even wrong website, dude. :D

What is it with men and comparing everything to a car? Is it really that ingrained into the brain wiring that guys who were given little toys to push around as toddlers that then grow into grade school students who drive imaginary cars down the hallway while making engine sounds with their mouths end up seeing their world as adults through the view of a windshield? Nah nevermind, let's not delve into psychology here, it'd be a waste of time.Anyway "dude," have you read many articles on this site? AT doesn't cater specifically to the audience you think it does and perceive that you fall within. In my opinion, that's one of the nice things about Anandtech. It's writers explore a wider range of technology in greater depth than do the dinosaurs of the desktop computer era that have yet to realize that overclocking and tinkering is now well controlled by hardware manufacturers that manage even that experience to the point where it's basically a walled off sandbox that only leaves buyers with the impression their extra expenditure is giving them something more rather than genuinely rewarding them with something worthwhile.

I used to liquid cool and overclock, until a tiny leak destroyed a motherboard and CPU years ago.These days my PCs are so fast that I don't need to overclock, but if I wanted to, I wouldn't even try it unless the cooling liquid has a low enough boiling point to be MUCH more effective than air-cooling, like the liquid cooling used in some tablets.

"like the liquid cooling used in some tablets."You mean vapor chamber technology, which has been in use for several years in the PC space already and is in pretty much no way comparable to water based liquid cooling which is typically meant when talking about liquid cooling? Totally different technologies which shouldn't be conflated at all.

And I forgot to add to your "MUCH more effective than air-cooling" point. If you indeed mean vapor chamber technology, that is only effective in drawing heat away from the chips that create the heat. That heat needs to be transferred to somewhere where it can be taken out of the system (unless the heatsink attached via vapor chamver is literally the size of the wall around your room) and that is usually done via air cooling, i.e. having a lot of metal fins oriented in a way that a fan can push or pull air through them to cool them. So nothing magical about it.maximumGPU - Tuesday, August 2, 2016 - link
I'd appreciate if anyone can answer this:Can you make a custom loop cool better AND be quieter than a high end air tower?
Unfortunately I can only find contradicting opinions on this, anybody with direct experience cares to pitch in?
