does pump max speed = reduce life

[BirdyTheMighty]

is it ok to run the pump at max settings 24/7  (d5 vario on 5th setting) or will that kill the pump quicker. thinking on getting a second pump but temp never goes pass 60c

[Devon_Pearce]

it will kill the pump faster, however you should still get like 2 years out of minimum even doing that

[Enderman]

running the pump faster does not make your temperatures lower

adding a second pump does not make your temperatures lower

ya if anything cooling will be worse since the fluid is going to spend less time in the rad  where the cooling actually occurs

[BirdyTheMighty]

no its that the flow meter does not even move a inch unless i set it on max setting but  if i say leave it around 1-2 the temp does not go pass 60c when stressed .

Having an increased flow rate is actually ideal.  http://hardforum.com/showthread.php?t=1671889

On top of that, some pumps will actually become ruined if you run them below max speeds.

Anything run on max load will guarantee reduced life expectancy. Unless it is designed to be run on max setting and states it as so. You can always run a system of either push, pull, or combination of both pushing and pulling. Fluid dynamics is applied whether it is water or air. Dual pumps can reduce load but really is not needed in most cases and having a low pressure/high flow is better as more heat transfer/exchange occurs vs a High pressure/low flow system as you reduce the load but still maintain that desired cooling you will need.

but increased flow rate does not affect temperatures

unless youre comparing to a flow rate which is extremely low, like below 100L/h

 

Also the D5 is a variable speed pump that doesn't get damaged by running slower

[BirdyTheMighty]

thanks for the reply i was just wondering cause my flow meter is not moving until it hits 5 on the pump

 

The temps been fine real temp has been on for 20 hours

the D5 Impeller floats on a hardened ceramic bearing. its Lubricated by water and the top plate that balances the impeller on the bearing is made of a Hardened plastic.(not sure what Kind)

the Impeller is the wear point and its replaceable. a D5 has a MTBF in the range of 100,000 hours at max speed. there is one moving part, its replaceable. 

i have one that's from 2003... runs 8 hours a day.  hope that helps. things to keep in mind. dont use it in salt water, don't run it dry if you can avoid it. and Dont move the computer/pump while its running.
