water flow rate

[guyonwater]

Hi,

 

i'm new here this is my first post, hello everyone

 

I'm running a water cooled rig, with a single loop cpu + 3x gpu + 2x 480rad + 1x 360rad + 1x 140rad

the loop is powered by a ek d5 bay res pump. current water speed is 220 liter per hour. (with max pump speed)

 

under heavy gpu+cpu load temps get to around 45-50C.

 

question: would i benefit from higher flow rate?

i'm thinking about adding a ek dual d5 pump to the loop and running the system with 3 pumps, but i'm unsure how much it would help regarding temps!

(or even dropping the bay res and going only for the dual d5 would also be an option)

It looks like you're just below 1gpm which is pretty good and normal. Most blocks don't scale very well above 1gpm so you probably wouldn't notice a big difference in temps.  If you want to be sure, find a review for your exact blocks that shows performance at different flow rates.  Some scale better than others

(xtremerigs.com and thermalbench.com are usually my go-to sites for watercooling reviews)

Edit: for example, ek's gtx980 block would maybe show .2°c improvement from adding another pump. Maybe .5° from 2 additional
