Enermax pump (flow rate?)

Hi guys, the other day I found out that the Enermax LIQTECH II pump has a flow rate of 450 L/H, which goes way beyond the standard of the common AIOs like Corsair, Cooler Master, which apparently have a flow rate around 60 L/H.

That sort of block would be perfect for me to purchase and modify my Maelstrom block mod and Alphacool XT45 360 radiator (just arrived, I'm currently using a Barrow 360). But the only 120mm unit available is the The LIQMAX III, which has no specification of flow rate (completely different pump). The cheapest LIQTECH II (240), with taxes for my country, comes out almost the price of a full loop. So it won’t work for me.

Does anyone know if the Enermax blocks have the same pattern, same flow rate? I wrote to them a few days ago, but still got no response.

EDIT: Enermax responded me after a couple weeks and the pump of the Liqmax III is on par with regular AIOs such as Asetek (OEM units for Corsair, NZXT, Thermaltake, etc.), Cooler Master and DeepCool. Just the Liqtech II has a more powerful pump (as advertized on the website).

Hi,
Third of the rated speed of a normal D5 which is 1500 l/h
Ideally 50% of a D5 would be a better minimum 750 l/h seeing most people slow down D5's to half their speed.

Even ek has low speed pumps like that that are stand alone pump reservoir combos.

You mean the flow rate of the LIQMAX III? My post was a bit confusing.

Hi,
I was just commenting about 450 l/m pumps in general
Most regret buying them eventually
1 rad and cpu block okay but add another water block and rad flow will drop a lot.

But 450 L/H is twice a gallon per minute, which I read here in this forum that 1 gallon per minute is enough for a loop. I think it said that more than that gives marginal temperature gains.

If the Enermax block can deliver that, I can have a custom loop with a block that will give me more or less the same performance of a custom block with a pump. I’m trying to keep it simple. I might never get a GPU block. I’m just might upgrade my i5-9600K to an i9-9900K.

The 360 XT45 is a bit overkill for that, but I was curious about it and I'm keeping it outside the case (I can leave the fans at low speeds as well). It looks good, I can control the fans with a knob (modded a fan hub with a voltage controller), that sort of thing. And I love the black soft tubing.

When manufacturers list specs they pretty universally use the best numbers they can find even if they have no bearing on real life.

In this case the pump flow rate is for the pump itself if there is no resistance to flow at all, like not even any tubing. In a real loop the flow rate will be much much lower and in the sort of pump and block combos like the Liqtech the flow will be a fraction of that 450L\H figure. I would doubt it would be much different to any other similar AIO

It might give the loop a bit more pressure / flow. The regular AIOs have basically no flow rate. Someone here said that the old Thermaltake 2.0 (Asetek pump) had advertised its pump as 60 L/H, which is just a fraction of the Enermax. The Maelstrom block that I'm using is basically the same as the Asetek one (the plastic cover even looks similar). It has basically zero pressure.

If I can get a block with more pressure / flow, it might prevent me from getting a separate pump / block.

The pump might be slightly better than some other AIO models but they still use very very fine cooling channels in the cooling block.

Modern water blocks from EK, Watercool etc use wide channels and low flow resistance to allow typical loop flow rates of around 200-250L/H
Its a high volume system

AIO's use high resistance, low volume systems so their flow rates will always be much lower.

So Enermax is not answering my questions (Facebook as well), just telling the pump has 3000rpm. Which then makes me think the Liqmax III have a regular AIO pump and they don't want to say it, differently from the Liqtech.

But I found that the Brazilian post office has a purchase service abroad with warehouse in Miami to rerout the package, so I can buy by Amazon (I wasn't finding a seller for the Liqtech that ships to Brazil). With taxes, the Liqtech II 240 (which has a pump of 450 l/h) will come out the same price as the Liqmax III 120 that I found before. The good thing is also that the Liqtech II 240 has a 40mm radiator. I can sell later only the radiator and the fans, because these mods are kind of popular here.

Even if the block has flow restrictions, and I imagine that if the pump has such a high flow rate for an AIO, they might have made a different design, it will be better than an ordinary Asetek pump.

I really don’t want to mess with blocks, pumps and reservoirs (even a small one to check the flow). I’m really interested just in a good block / pump combo and forget about it. The radiator that I built outside and the fun hub with manual control (six Akasa fans in push pull) that I modded is enough.

Shame the Swiftech Apogee Drives are no longer available. Would have been an easy solution for you.

Yeah....the little girl hentai avatar is really creeping me out....
