High Flow NEXT issue

Monday, May 1st 2023, 2:28pm

Hi,
i'm an happy and proud user of an High Flow Next from this december, but now i have a strange problem:
When I start my pc HF Next show about 200/150l/h, but than immediately start to drop, sometimes until 40l/h, sometimes untill 80l/h and sometimes to 0.0l/h!!! Always. From more than 1 month.

But i know that it's wrong because when it show 0l/h the flow goes on, i have no cooling issue, even with more than 500W of heat, and the rpm flow signal from the same HFNext always show about 2500rpm.
I can make a video if necessary.
What can I do? RMA?
PS: anyways it's possible to know how many L/h mean 2500rpm?
thanks in advance for the support, Nick

Hey Nick :)


on my D5 Next 2500 rpm is 66 liters.


I also have the problem that my HighFlow Next shows 0 liters at system start if the flow is below 80l/h.
Only when the pump delivers higher speeds for a short time (increase flow) does the HighFlow display values ​​again.


I've had my pump run at 85% since that's where the noise bothers me the least.
Faster and slower the frequencies are too annoying for me personally
