They can be throttled back for noise, but WFO is how I've always ran all the pumps on a AIO
Would I do that using the voltage control option in the BIOS, since this doesn't have a 4 pin connector? Do some pumps come with PWM control? Thinking maybe I got the wrong on, here, damnit.
yeah, that's how I do it, just set that header to 100%
So does everyone just run pumps wide open?

Depends on the AIO/pump. I ran my Kraken x62 and H110 at 100% at all times because they were quiet even at max. My current one becomes louder than any fan I have at anything over ~60% so I keep it low for the quiet.
How do you adjust pump speed? On Amazon, Enermax answered my question:
Q: Is the pump suppose to run at full speed, or can you control pump speed thorugh the bios using the bios 3 pin votage control?
A: Pump is always on full speed to maximize heat dissipation. Fan speed is controllable through BIOS however
Really a stupid answer since you could run every everything WFO to "maximize heat dissapation."
Can you BIOS voltage option to control pump speed, or would that damage the pump? People report teh pump is dead silent wide open at 3200 RPM, but I just hate running anything WFO unless it is needed.

You can control the pump speed by reducing voltage, but you shouldn't on an AIO. Don't worry about running it full speed. It's designed to run that speed, it's not like you're redlining an engine here.
LOL, yeah that's how I feel about it! Anyway, the manual says to plug the pump into the CPU fan header, so I did. Booted to BIOS, and the MB immediately controlled the pump speed, using the default fan profile. The pump was running at 1850 RPMs, and the fans at 1450. Idle temps was 30C in a 22C room. So, for now, since the manual doesn't say ANYTHING about setting the BIOS to run full speed, I have a speed controlled AIO pump. If it fails due to undervolting, that's their problem. They should state that in the manual.

That's... a pretty cavalier attitude. I seriously doubt that they will consider it to be their problem.
The reason they tell you to plug it into the CPU header is so that if the pump fails to turn, your motherboard will see the 0 tach signal and react accordingly.
You should probably not leave it like it is. Set it to 100%. I've seen cases where the voltage controlled header dropped below the run voltage of the pump and it stopped with the machine running.

all mine run full blast.
no, that would be a you problem, but i doubt it would happen. leaving it on auto is going to be fine just potentially not optimal. but its your call. you can balance performance noise to your taste.
ps: you should keep your post in one thread. you have so many going its hard to keep track of and they all pertain to the same system/aio.
There is nothing on their website nor the manual that warns about adjusting speed in the BIOS. When I contacted the company about it, they simply said it is suppose to run full speed to "maximize pump flow." I asked if it would harm the pump to slow it down using voltage from in the BIOS when connected to the CPU fan header, and got no reply. I'm not violating any usage requirements the company has published.
Well, for warranty, it would be their problem because they do not say anything about adjusting the pump speed.
If it doesn't create a problem, then I'd like to spin things down during lower stress. I don't think the pump makes any noise. Anyway, the fans at 1450RPM make a LOT more noise than anything else in the case. I'm not sure if it is the fans, or the fact they are slowing into a radiator, which would mean airflow over the radiator is making the noise, and really no way around that given equal airflow - even if I replaced the fans, the airflow would be the same all things being equal. So no benefit in that. I like a very quite system. My old air cooled OCed X58/Core i7 system was almost dead silent under stress, but I had the advantage of using two 230mm intake fans spinning at 1200 RPMs, one in the frontand one one the side blowing directlyonto the video card and DPU cooler/VRMs, a low speed Roasewill 140mm back fan, and a 230mm top exhaust fan, plus a very efficient tower cooler using the Gentle Typhoon 1850 RPM fan.
The ITX case I have has the ability to mount 7 140mm fans, two are taken up by the new 240mm radiator. Not sure how I will do this yet. It depends on when I get my system up and running and can check temps in a closed case.
Anyway, will low voltage harm the pump? I have no idea. Some electrical devices are meant to run at low voltages to control speeds, some are meant to allow for some voltage drop, but only a specific amount, and some are not.
As far as keeping everything in one post, I hear you, but I think a new thread should be posted for each single question. Yeah, we always digress in threads, but ideally, it should be one question/subject per thread. Otherwise, the thread topic changes over time, and anyone looking for specific answers to problems will never find it buried 15 pages in a thread where the title has nothing to do with the ongoing, mutating posts. I know I have talked about pumps in other threads, but I try to remember to post "one question, one thread." I trust you can see the logic behind that?
For instance, I'm going to post a new thread about voltage and fan risers, even thogh the fans are on the same AIO system.

web searches will bring people to a thread regardless. for people trying to help you, like myself, it get confusing when there are threads allover.

I'm telling you - they will not accept responsibility for anything, regardless of what they have published.
This is a backwards expectation on your part. I'll take a guess that Nvidia has never published a warning about pouring soda onto a running GPU - do you think that means I could do that and get full warranty replacement from them?
You came to this forum to post a question asking for advice. If you're going to argue with every answer you get and do whatever you want anyway, why did you even post?
Although i am very apprecaitive of you ongoing help, we'll have to agree to disagree about the one question, one thread deal. I think ti makes the most logical sense. Many forums even specify one question per thread. Otherwise, they call it "thread hijacking."

you can hijack you own thread but whatever.
To answer your question, I post and ask questions, or disagree (You call it arguing), in order to find factual information or to come to some tentative conclusion.
I'm just disagreeing with you about warranty and pump speed. Pouring liquid on electrical devices is obviously abusing the product. Running an AIO pump slower than max is still up for question. Some people here DO NOT agree with you, and have stated they do adjust their AIO pump speed.
Comments like this, "I'm telling you - they will not accept responsibility for anything, regardless of what they have published" deserve to be "argued." How could you POOSSIBLY know that?
I appreciate your help/advice/opinion, but I will question you if I feel the need. Now let me ask you a question: If you don't want to be questioned, why do you post?

Fair enough, but why not try to keep it "one subject one thread?" Isn't that just good housekeeping?

By your own admission you have zero experience with AIOs. I have lots. You asked what might happen if you undervolt an AIO pump, and I told you - from personal experience - that letting the motherboard undervolt the pump might result in the pump not turning at all.
If you want to let that fly and assume that Enermax will accept liability for whatever happens, power to you bud. I think you'll be unpleasantly surprised.

I took that information as valuable too. I don't want to undervolt it enough to cause it to stop running.
This is my first experience with AIO, but I have a bit of experience in other areas and I understand about undervolting and damage to certain motors, or them failing to even turn at all. Some will run with really low voltage, but it will wear out the motor faster or even cause it to fail:
This is a good overview:
- The device might have a starting circuit that’s only designed to run for a short period of time. Due to the undervoltage, the device may fail to start and thus leave the starting circuit on all the time, quickly destroying it. This can happen with some motors or lights.
- The device might have a regulator that supplies only the amount of power the device needs. With a lower voltage, the same power requires a higher current. The higher current may cause a device with a fixed resistance to overheat and fail. This is common in laptops and other digital electronics.
- The device may have some circuits that should never operate at the same time. Due to the undervoltage, the device’s control system does not properly start up or initialize, allowing circuits that must never operate at the same time to operate at the same time. This can happen with H-bridge motor controls and inverters.
- The device may use MOSFETs to switch high-power electronics. With an insufficient supply voltage, the MOSFET may not turn all the way on, leading to a higher on resistance than normal. This higher on resistance causes high power consumption in the MOSFET, causing it to overheat and fail. Source
I read on some review the pump speed was 3200RPMs, but the Enermax specs do not state the pumps max RPM. I'll find out tonight. It's max power draw is 0.7V.

i would recommend that you take it off auto, put it to full blast and see if the noise is ok. if not, turn it down a little at a time until it is and then leave it there. then you wont have to worry/overthink this silly non issue.
I was thinking about doing the same thing. I'd just have a flat fan curve profile at whatever speed is best. I cold also make the profile flat unless it starts to rise above X temperature, tehn allow it to run fluu out when or if needed. It's a good option. Thanks.
The max RPM is 3200. I set min state at 2400. I tested it at idle in the bios and no diff in temps all the way down to 1500RPMs. After 50C I have ramp to full. <shrugs>

that should be fine it will just go to full when then cpu is actually in use.
Finally got a reply back from Enermax:
"My motherboard does not have a pump header. I'm just asking will controlling the speed of the pump in the BIOS harm the pump?"
"Bios control pump speed won't harm the pump."
