I've got 3 pumps that are 100%. I get over 300lph with a mora iv 600 and koolance quick disconnects. It would be easy to change the mora pump to 80% as its controlled with a quadro. I guess it wouldn't be hard to change the bios to 80% for the ek dual pump top either.
Do you run your pump at 100%? Does it shorten it's lifespan?

Your best bet is to first run all fans at minimum speed so you can hear the pump. Start going by 5% increases, until you’re happy. Then tune the fans. You may notice that sometimes you can increase the pump speed without noticing it over the fans, but sometimes even if the fans are louder, sometimes the pump can be noticeable, specially some screamer’s high-pitched from Corsair and similar.
Better still, find the point (%) where the pump is quiet, and keep it at that speed until the CPU needs all the flow it can get. Mine will only go to 100% of reaching 80C, which never happened in games. Setting the speed gaps too low, the pump changing speed constantly will be way more annoying and noticeable than a constant speed.

Thank you so much mate, that's very informative! I am really looking forward to getting this now! Hopefully end of the month!
I'm using a Lian Li Galahad II LCD which uses the Asetek gen 8 pump.
The pump is too noisy at 100% so I run it at 40% most of the time, including gaming. Then when I do encoding over night using ffmpeg, I set the pump to 80% because CPU usage will be pegged at 100% and I won't be around to hear the noise it's making.
People say this pump should be quite quiet, but the pitch of the buzz it makes above 70% gets under my skin
Temps are fine doing things this way

I guess it's just a matter of finding that sweet spot between temps versus noise

This might not be the best idea - dedicated pump headers are typically rated up to a 3A maximum current draw, whereas fan headers tend to max out at 1A.
It may work out fine in practice depending on the individual hardware, but in an absolute worst case scenario you might need a fire extinguisher handy

I honestly doubt an AIO pump will be pulling more than 1 amp.
A Laing D5 is rated for something like 22-24W which is 2 amps max. Even then, I've never seen a "proper" i.e. discrete, water cooling pump, that didn't have its own Molex or SATA power connector.
Nice that motherboard headers are being uprated but I wouldn't worry about fire! They should burn out first.

A molex or sata power connector
So can run off a 1A header for speed control
Most pumps probably aren't that low powered though which is
Why they also have sata or molex power
In my case I have 2 x 3A headers
And although it's very unusual also 2 x 4A headers
Doubt there's a pump out there this board can't handle
Though I still wouldn't connect one to a 4A header without also using
The sata/molex power anyway
But I did say depends on your motherboard
Just in case
But should always read your motherboard manual first
Before planning where to connect stuff
Especially if want to daisy chain fans off a 1A header
Without a powered hub

IMO It's unlikely to make any noticable difference to the lifespan of the pump. BUT running at 100% is generally noisy, with minimal performance difference, so depends what you want from it.
I run my D5 at ~20% as standard, but it does ramp up a little bit if the temperature differential (before & after my GPU) in the loop gets bigger. Around 20% is when my pump is quietest, and much more & it starts being audible.

I love how, no matter what model it is, I hear nothing but good things about the ALF range; I'm genuinely excited to finally get mine, but due to deciding to change cases and 'do it once do it right' and go big boy 420MM size, it's going to be awhile before I do. It'll be my first ever watercooling or AIO experience, and I hear nothing but great things!
Thanks for your input mate
It's appreciated!
I've got two 360 rads and a 480 with CPU and GPU in a single loop. I have run my D5 on 100% since day one and don't plan on ever turning it down.
Same for my last D5 that was about 10-12 years old and still worked just fine. It was just old and more versatile pumps were available.

Thanks mate, wow 10-12 years, that's outstanding!
Cheers dude, I'm all about the silence versus temps.

No, never run mine at anything other than minimum.
I asked Corsair about this and they told me that it really doesn't make much difference to performance, but it does make a lot of difference to the noise it makes.
Running them faster will shorten their life, but they are designed to last a looong time. I think it's more likely to die of just random failure than actually wearing out.

Thanks for your input, I like to air on the side of caution, but also 'if' I'm switching to water, I want my cake and to eat it, otherwise what's the point; so to be able to utilize the pumps efficiency versus noise ratio the best, is critical to me. Otherwise I may as well stick to air. I appreciate that there's always a trade off, but I'd rather something be over compensating and last longer than intended, and live upto it's reputation/abuse from a high wattage CPU, than have to be babied.

Some of them have variable speed. Probably the best solution.
