Static vs ramp-up AIO pump.

[ivanrcks95]

More of a curiosity question than anything else as ive heard mixed responses about this topic. Is it better to keep an AIO pump running at the same rate all the time, or have it ramp up with the fans? Ive personally ran my AIO pump at 50% locked all the time, with only my fans ramping up as temp goes up. This way the temps are still perfectly fine (76c max after 10min R23 on a 5800X3D, 65c or less in games), and I dont hear the pump at all, its dead silent. Ramping up the pump does help drop these temps by another 5-6c, not an insignificant amount, but then the pump gets very loud, louder than the fans. Is it worth it though? Does the pump experience any extra wear when constantly ramping up and down compared to being locked at 50% speed? Would be curious to get some extra insight.

At what % cant u hear it at all? 60?  80?

 

keep the curve between 40 - * your answer *

Anything above 50% i start to hear it, as soon as 55% its audible. My fans are dead silent even under some load, so it makes any pump noise more obvious. Thats why ive kept it locked at 50%. Is there any benefit of having it go down to 40% and ramp up to 50% instead of just having it fixed at 50%?

40% is a " my pc is not doing anything" type of speed  (aka idle)  while using it i would maybe go over 50

What's that AIO? Never had a pump louder than fans at 50% speed, mine runs 95% and I can't hear it

NZXT Kraken X63. Ive had it for 3 years now, and the noise it makes above 50% has been the same since day 1, so I know for sure its not a recent issue.

 

I run Arctic P/F fans all the way through, the case is a Lancool II Mesh Performance, so the fans, even under load, dont need to go above 50% fan speed, which is around 1040rpm based on my fan software, and at those speeds theyre dead silent. The pump makes like a humming noise above 50%, and yeah it is louder than the fans.

Either you are noise-sensitive or that pump is crap. Leave it at whatever the highest speed is that doesn't bother you so that the pump lasts longer.

I decided to look into X63s online, and seems like its the crap pump part.

 

Pretty much every video or post I come across is people complaining about them being noisy above 60%, same exact noise mine makes. So seems like its just a noisy pump in general. Its lasted 3 years, so no reason to switch it, and if its completely silent at 50% with the temperatures under control, seems like theres no reason to leave it running faster anyway, or set up pump curves for it to ramp up/ramp down.

Weird..

My P14s start humming around 900rpm, my pump is constant 3200rpm no noise  

Methinks your pump is defective

Yeah ive heard about the Arctic hum, maybe I got lucky, but my sets of P12/P14s and F14s dont do it, or I cant hear the frequency they do it at lol

 

Also see the comment just above about the pump, after a quick research session, seems like its just a X63 thing, no reason to suspect its faulty if its been 3 years, I think theyre just noisy pumps in general.
