Oase alphacool AP1510 Kreiselpumpe 12 Volt

[Shocker003]

Hi,

I am ready to upgrade my pump, so i will like to know if there is an issue or problem(pump failure) with this pump(Alphacool AP1510 Kreiselpumpe 12 Volt). It´s cheaper than the D5 and i intend using it with the Swiftech MCRES-Micro. What do you guys think about it:shrug: . I will still be using the other watercooling components in my sig(the old pump has to go). sorry for my poor english.

Hard to say about reliability since not a lot is using this pump. However, performance-wise, it's a great pump as Martinm210 found out ;) If it is cheaper in Germany (which should make sense), get it and you won't regret it.

Thanks Xilikon for the quick reply,
It´s about €89 here and the D5 goes for €106.
Am just afraid of failure:confused: , does it mean that there is no one in this forum that has been using the pump.

Personally I prefer the D5 or DDC though, the imo misleading advertisement (6 m, 17 W) really annoys me and the few loops i build with the 1500 and 1510 were all run at 12-15 V in the end as customers found noise on the higher levels unacceptable (they wanted WC for a quiet system in the first place).

Has any of your costomer reported of pump failure and at 15v how much head do i still have.:confused:

Like Fairydust wrote; It´s too loud pls what do you think and at what volt do you run yours. it good to know their is someone out there using this pump, at least i can get first hand infos from you:D .

[eva2000]

yeah it's loud.. but i'm not after quietness but performance with my dtek fuzion + 4.5mm nozzle.

i run it between 12v, 15v and 18v when i need it to :)

[Shocker003]

Thanks Eva2000, am equally after performance too, i will like to reduce the speed of my rad fans as i pushed the voltage up to compensate for the weak pump in my sig.

Does nobody like the Swiftech MCP655??
It is nearly the same as the original D5 but costs about 79,99€ at Aquatuning.

Isn't it a good choice??

[eva2000]

MCP655 is good too.. i have several water cooled rigs 2 use MCP655, 2 use MCP650 and one using AP1510 :)

[qujck]

ok because of the price i would suggest it for Shocker003 instead of the Kreiselpumpe for 10€ more.

[Xilikon]

MCP655 is just a rebranded Laing D5 and for that price, it's a much better choice.

[qujck]

yes i think so, too :)

I have order the Alphacool pump already and i intend giving it a shot.
So what do you think eva as you have both pumps in service:confused:
NB: I can still change my order:rolleyes:

[qujck]

i do not know the Kreiselpumpe, do you have a link??

[Martinm210]

The motor on the pump seems to be of very high quality. It's very heavy and efficiency overall is very good. The only part I think would have durability problems is the plastic shaft mounted impeller. If you can find a source to replace the shaft and impeller, I bet that's all that would wear out on it.

The pump does have a tendecy to vibrate a little more than the D5 or DDC, but once put on a nice thick piece of foam and isolated, I didn't think the noise was really that bad. Performance was really good though...it suprised me.

I'm just not sure about the DC-DC converter, I think it has very poor efficiency and I wouldn't be suprised if it draws 100watts at 24V. It kicked the circuit breaker on my cheap PSU (65watt max) at only 18V.

I would probably use a true dedicated 24V PSU if I was going to run this pump.

[qujck]

but do you think it is really necessary to use it with 24V??
It is a very powerful pump, and 18V will do it.

[Martinm210]

No, you don't need to.

15V is pretty darn close to DDC 3.2 with top or D5 performance, but 12V would be less performance than a D5 or DDC.

I would at least run it at 18V if you wanted to make use of the performance advantage it has:

Meanwhile thanks Martin for the advice on the pump. I will start searching for a better pump shaft and impeller. I equally read your review on the pump, am more than impressed with your work. keep the good work up:up:

[Shocker003]

I want to thank everybody that contributed in enlightening me about pumps. Am still waitting for the postman. I will still ask for help if i run into problem later. I wish you all a nice weekend.
NB: sorry for my poor English:::

:clap: :cheer:

Now you should get some slightly better temps Shocker :up:

;) How re you doing? I hope so too:yepp:

[Shocker003]

Hi Gents,
i finally got everything working and it´s a monster, compared to the tiny eheim 600. Well am a little disappointed with the temps am getting.
Am running it at 18v and my temps are almost the same with the eheim 600 station:(

AP 1510
Core 0- 37,
Core 1- 34,
Core 2- 34,
Core 3- 32,

Eheim 600
Core 0- 35,
Core 1- 33,
Core 2- 33,
Core 3- 30,
Am confused:confused:

My question is should i run this pump with 24v to get this super cooling effect that i have been hearing about. Room temp. 20°c:shrug:

[Boogerlad]

well, eheim has low heat dump. alphacool has high heatdump. unless you add more blocks and more rads, the difference is minimal. even then, the difference will still be quite small.

[Waterlogged]

Yeah, I think the dump from the 18v might be doing you in Shocker, have you tried 12V or 15v yet? Pic of setup?

[Martinm210]

Yeah, sounds like your flow rate gain is fighting pump heat dump. But now that you have the extra pumping power, you should consider tinkering with more restrictive nozzles. It's been shown on the EK that an RD30 at up to 21V is gaining temps over lower volts, so I think the Fuzion and really restrictive nozzles would have a similar behavior.

[Shocker003]

Here are some pics and am running it at 15v for some time now and it idles at 36°c, i will still get it down to 12v and check if the temp will still drop. I presume it´s dumping a hell lot of heat in my loop, DAMN!!!
What can i do to improve my temps.:shrug:

So what should i do to improve my temp. Most people in this forum, went like i should get a stronger pump to get better results but i haven´t seen any lower temps. yet:confused:
I have a 12v converter from my old Eheim 600 station pump, will it work with the Alphacool AP 1510? It´s converter is tripping my computer off..GGGGRRRRRRRRRRRRRR!!!!!!!!!!!!

[Shocker003]

Thanks to all that helped out, i lost 5°c after dumping the converter and connecting directly to the computer power. You advice(12v-15v) worked like a charm Waterlogged:up: :up:

Room temp at 20°c
