Can you use two pumps in parallel or series in order to use more rad's ?

Wanting to use more rad's in my system for when i purchase a gpu and chipset water block so that it does not raise my temps too much but i'm concerned the flow rate will be reduced and wondered if putting to pumps in series or parallel would work ? . Thanks steve
 
It is normal to put pumps in series when doing this, one straight after the other, they have to be an indentical spec also. If you have DDC pumps then there is a specific replacement top deisgned to combine two pumps into one, which only has the standard one inlet and one outlet barbs so it is a much neater assembly. However, if you're buying an additional pump and an additional rad then you only have to buy an additional res and you can dual loop. To me that is always going to be preferable to putting eveything in one loop as there is no risk of temperature of your first loop being affected. Sure there will be a bit more tubing involved compared to going for a two pump in series single loop but the extra hassle is worth it imo.
 
The other advantage of a two pump loop is if one fails your kit will not fry.
But pumps don't fail that oftern and there are other ways to protect your hardware if temps start to rocket.

Use martin liquid labs flow calculator to check out the various flow rates of different combinations and duel pump loops

Xspc have just released a Bay res with needs 2 DDC's

Thanks guys will take a look at the link. At the moment i have the thermaltake big water 750 setup and temps are ok but putting a gpu block an a chipset block in the loop would raise my temps and would have to increase the day speed's which would increase the noise and i leave it on overnight so would prefer to add an extra rad to the system. Thanks steve
 
Lol was cheap enough at the time only paid £75 for the full kit over a year ago
 
I guessing that was aimed at the bigwater...
In all honesty a tower air cooler is better that the bigwater, if you want to upgrade your loop you might as well sell it and start again (sorry)

Whoops-a-daisy.

Scrap and start again tbh. Not possible to add a second pump to that system I'm afraid, unless you can source the exact same pump used in that bay res thing, which if even if you could would be a waste of time.

edit: OR, if you are satisfied with the performance of the Thermaltake on your cpu only loop, then I go back to my original reccomendation that you add a dual loop for your gpu and NB. That is your ONLY option, unless you rip out the thermaltake and replace with custom kit, and even then I would still reccommend dual looping for what you want to do.

Agreed your just wasting money really trying to better a loop that's weak in every way. Better off trying to pick up some 2nd hand parts. Theres a DDC ultra for sale on the MM for a very good price on a brand new top of the range pump. Also PaulyD has a TC PA120.3 at a decent price.

Thanks guys no offense taken, funds are limited at the moment but will start an sorce the parts from the mm over the next few month and change my setup for better quality parts. But it has served me well and will prob use it for something different or build a second system and put it on the bay them use the money towards a new custom setup. Always new it was not much better than a decent aircooled setup
