D5 Pump question

[HaKN !]

Is it okay/safe to run this pump on 100% speed all the time ? i was just thinking about its life span. im using my pc ca 12 hours a day

EK-Quantum Kinetic TBE 200 D5 PWM D-RGB - Plexi​

Yea, cooling wise it's internally cooled by the loop water. Just account for the 30-35w extra heat in your loop. However, its a PWM pump so it kind of defeats the point of running 100%... right?

I’m on pump 2 over a span of 11 year and 365/24. It has been running 100% all the time.

Ohhh okay wow damn, didn't know they were that reliable, but thanks !

Okay didn't know that either , thanks !

If you were going to run max speed all the time just get a regular D5 and save some cash. It depends though on the noise. Some ppl can't hear it some are bothered by a the slightest setting like a D5 at #4 or #5 is audible, etc etc. A PWM D5 however will let you decide when and where it runs max speed so it can be as quiet as you want.

It's already in my system and i thought just to set it at 100% and i was really impressed by the noise as in almost none to my ears , i can even hear my Noctua nf 12x25 more then the pump. its vibrating a little. the only time i can hear it , is when i power up the pc, but thats just for a second

You would be fine to run it like you want, but you will want to do some testing.

Many will say that there is a point of diminishing returns with flow rate. In other words, you may get better performance at say 50% than at 100% RPM of the pump.
Point being, just because you can do it, doesn't always mean you should

I don't think there's a point of diminishing return on a D5, those things need all the PWM (DC) scaling it can get. They're not DDC's that get 95% flow at 50% DC, duty cycle.

I dont know if its me or my brain playing games with me but i tried manye settings, all the way from 25% and up to 85% ,it just feels like my gpu just keeps climbing , but when im in 100% it stays flat 44c no matter what , and cpu tops out in 69c ( Aida64 FPU stress test )

D5 pumps have lower head pressure so they really need max rpm to compensate.
