I have this pool going in another forum but since OCN is my favorite forum..
ok i got this bug called "more pump" ,i'm sure many of you know what i'm talking about
Here is my question .. do i really need it and what can i expect from additional pump ?.I want to shave off around 2~3C
I was against all type flow /temp sensors but i want to add some now,this is where i'm at now , i try to take water temp reading with digital thermometer Range31C~43.9C) but
couldn't so i figure the water is under 31C ,ambient 80F (27C)..below 4º Delta

Bigger rads first, the additional D5 will dump extra heat into the loop.

I don't plan on additional/bigger rads right now just pump
Thanks theseeker

If you add another D5, do it in serial and turn it down to 3. Just my 2 cents.

+1 Extra pump = more heat. Even turn down, it would take a lot of flow to offset. Add more rad.

The only reason to use more than one pump is to increase reliability or if you have a super restrictive system. You really won't find that adding pumps ever decreases temps unless you're running cpu, 3x gpu, ram, and mobo blocks as well as multiple radiators. I always run multiple pumps per loop since they are always quite restrictive and way under 1 gallon per minute without a second. If your flowrate is under 1 gpm then a second pump will help decrease temps, but minimally. I ran my current setup on 1 pump for a long time and after adding the second pump in serial I saw no temp differences. The rig I'm building will be using 4x uber d5s, but the only reason for that is 6 radiators and 13 blocks and to look awesome.

Yes stall i know all this and should apologize for not asking direct question which should be.. can i jump over 1.5 Gpm hump considering my set up with additional DDC 3.25 ..the problem is i don't know exactly what my Gpm is right now ,something similar to this:

P.S. I slowly getting to the point of giving up,don't think is worth the effort and the lettuce ,love my temps ..it's just that urge for even better

most likely not, with 2 pumps, whether 655s, 355s, 35Xs or the like you won't be seeing over 1.5gpm unless it's just a cpu with 1 rad. You'll probably be around ~1.3gpm with two DDC 3.25s. 3x DDC 3.25s will get you over 1.5gpm for sure tho with your loop.
