Yea my VRMs when its 21°C in the room barely reach 60°C so not too bad. I raised my case off the ground a bit ill test it again in winter.

@AT-Edward
Any news on the Eiswolf availability?
Will the pump be built into the GPU cover block?

Thanks

2 weeks, than you can get the Eiswolf GPX-Pro.

There will be two versions. The AIO version and the prefilled stand alone version. Both have a pump on the block.

Thanks AT-Eduard!

My case is too small to fit the Eisbaer pump, do you know if the pump on the Eiswolf is strong enough to drive another 240 rad and cpu block?

Hi Acronynja,

yes, the pump is strong enough for a CPU cooler and a further 240mm radiator if everything is placed in a normal case. The technical datas of the Eiswolf pumps are the same like the Eisbear pump.

That's brilliant, thanks AT-Eduard!

Like AT-Eduard said, it will work.
But I would be careful about not getting restrictive CPU block and/or radiator. I've been told by people who know these things that the Eiswolf uses same basic pump as Alphacool uses in Fractal Design Kelvin (0.317 GPM / 72 L/h); which is a modified (no reservoir) Eisbaer pump (0.308 GPM / 70 L/h); which is based on the Alphacool DC-LT Ceramic Ultra Low Noise pump (31.7 GPM /72 L/h).

The Aisbaer pump is rated 70l/h (0.3082 GPM American)
https://www.inet.se/files/pdf/6912223_0.pdf

Thermalbench tested the Eisbaer 240 and recorded 0.3 GPM (67 L/h), within margin of error. wink.gif
http://thermalbench.com/2016/06/27/alphacool-eisbaer-240-cpu-cooler/5/

While Eisbaer has 3x or more flow than CLCs do, other AIOs with component pumps flow significantly more than it does.

For comparison,
CLC
H100i open flow = ~ 0.11 GPM (25 L/h). Keep in mind this is not loop flow, but free flow. This is typical Asetek pump performance
http://www.overclock.net/t/1371863/corsair-h100i-max-flow-rate-test-video-result/0_20
AIO
Eisbaer 240 loop flowrate is = ~0.3 GPM
EK Predator 240 loop flowrate = ~0.6 GPM
Swiftech H320 X2 Prodigy is = ~0.89 GPM

And these flowrates are middle to low side of what most custom H2O component pump flowrates are.

Actually, the newer CLC pumps hit 0.2-0.25 GPM in the coolers. Still nothing to brag about though.

My DC-LT runs a cpu+gpu+quick disconnect loop great so should work fine (although it's the higher speed version I have it controlled down to around the same speed as the low noise version). Avoiding high restriction CPU blocks is probably a good idea. Resistance not an issue for rads really, if anything I would avoid thick rads where there is more chance of the water slowing down too much. Only possible issue I see is filling/bleeding, guess the idea is to do it via the extra ports on the rad just not sure how easy it would be?

To give a feel for the flow 60 l/h with a 300W load still only means water leaving around 4oC warmer than it's coming in. Suggests to me a well chosen flowrate for a modest loop. Nothing wrong with a more powerful pump if you want the last few degrees of cooling but you may end up paying a lot for it relatively and probably only gain minor extra OC if anything...

Is this independent testing by adding an inline flow meter? Could you give us to this testing and data please? thumb.gif
