how much can a XSPC 750 pump take?

post #1 of 8
Thread Starter 
I have a XSPC X2O 750 pump/res combo
Stealyh GT360 radiator
Delta V3 cpu block
GTX 480 full cover

all in my loop, however temps are getting high, and i am thinking of adding another radiator but i heard the pump might not be able to push water all the way round?

i am getting over 80C on my CPU (When i run Prime and furmark) and this is with AcRyans PushPull @ 50% (1000rpm)
- i think i will need another radiator, or is my pump just weak?

cpu block is mounted fine.

thanks, any advice much appriciated

just my personal opinion here. the RASA kits are amazing for simple tasks such as a single CPU loops or a single GPU loop. I think when you start adding more than just a single block, you start to head into territory where it might be prudent to upgrade to some parts with a little more head room.

Not saying the parts in the kit are not good, but your heading into needing a bit more flow and some more raddage.

you could always add the next rad and see what happens.

Yea you would be heading towards a low flow, however, what you could do....


Since you're in an 800D and not really overloaded with space for rads, you could replace the 360 stealth with a decent deep 360 rad and some high performance fans.


A little side note, what temperature is your water? If it's cool your temps could be due to your mounting or low flow flow already, in which case more rad wont help.

What is the temp on the GPU also?


Edit:

Missed your fan speeds, turn them up lol.

If noise is a concern I would strongly suggest having a look at these:

I think it's mostly due to poor fans. Low RPM fans that already have terrible static pressure generally don't work well for a radiator. I can almost guarantee that putting a pair of scythe gentle typhoon AP-15's on there would drop it 5C instantly on the CPU, if not lower.

It could potentially be multiple problems though. Depending on if you're using distilled water only or some sort of coolant, the coolant could be gunking up the water blocks and causing flow issues, I've seen this multiple times (not personally, but on forums). It could also be due to too much tubing being used, causing some flow restriction, or also the fact that you're using a full cover water block on a GTX 480. A GPU water block that only covers the GPU wouldn't soak up as much heat nor would it restrict flow as much. I've seen plenty of people running XSPC Rasa 750 RX360's even RX240 kit's with a GPU only water block (not a full cover) and their temps are more than acceptable.

Even if most of the above doesn't hold 100% true in your case, your fans are definitely contributing to the problem.

I talked to a guy on here, who ran:

CPU block
3 SLI blocks
a RX360
and a RX120

off of the XSPC 750 pump for month. He eventually upgraded the pump (probably because everyone on here told him to do so a million times), so we don't know the longevity of the pump. But his temperatures were very manageable.

I would add a new radiator myself..instead of replacing it..If you see your pump having hard time, just order a new pump and you're set

Tricky thing with sli is that when in parallel 3 blocks have less resistance than 1 block (one third in fact )

I very much doubt you could do 3 GPU blocks in series and the temps probably suffered on the GPU due to a lack of flow anyway, but GPUs don't seem to mind as much as CPUs do.
