how much can a d5 handle?

Ragnahex · 21 Nov 2013 at 19:34

ok so there seems to be varying opinions on this looking around so how much do you guys say one d5 can handle? i only ask because my loop keeps growing (it's amazing it has a life of it's own and grows new pieces every week).

What do you have currently in your loop and what might you add in?

Most watercooling pumps can go a long way. Days were different when there werent specific pumps for watercooling (and some people used things like aquarium pumps) but now the pumps we use are much more powerful and so we tend to worry when we don't need to.

it's not a worry in my current setup. cpu gpu 120 360 soon to be another gpu and 240. More out of interest than anything else

Should give you a fair idea how much you can get away with

I am getting a d5 with 2 240 rads to cool a 4770k, r9 290 , motherboard and ram.
Is that true that pump should be in highest point of the loop or is that only to make filling eadier?

You mean res at the highest point? It can help but whatever works best for you. Only real thing to make sure is the pump comes after your res in the loop, so the pump is feeding off the res. Otherwise it'd run dry when filling the loop and that can damage/kill the pumps.

As for how much a D5 can handle, not sure really but it can certainly do a great job

I use only combo's, D5+xspc cube for this loop.
So for me pump/res is same thing, thats why I asked about the pump location.
Sorry, brain shortcuts :-)

This confuses me, as according to their figures I should be running negative pressure, with my XSPC 750/RS240/EX120/Raystorm CPU/Raystorm GPU, and have been doing so for almost a year and a half now with load temps hovering around 40C.

It is handy though, since it confirms my thoughts that a new pump will be wanted as my next upgrade.

From just looking at your list without checking numbers I'd guess you'd be running less than the 1gpm mark.

Negative pressure? :confused:

It's a fair indication but its obviously not going to be perfect. would be interesting if you put an uprated pump into the loop see if temps get lower.

Edit: just done the calcs with the closest match I could find and it put the pump running at 0.1gpm :confused:

WTH happened there haha. Either early morning maths has failed me or your pump is a miracle
