re-evaluating my loop - comments/suggestions?

post #1 of 8
Thread Starter 
So it's been about around 8-9 months since I got my water setup, I think it's time to flush it, so I'm thinking maybe I can take this opportunity to do some upgrades maybe. How good are the temps, what are some easy/cheap upgrades or changes I can make?

PC Specs:
i7-920 @ 3.8GHz 1.3V
GTX 285 SLi
(more specs in sig)

Water Specs:
CPU: Swiftech Apogee XT
GPU: Danger Den full cover block
Rad: XSPC 3x120 Rad Rev 2
Pump: Swiftech MCP355 Laing

Setup:
450

Water loop order:
pump+res -> rad -> CPU -> GPU #1 -> GPU #2 -> pump+res

Air flow order:
Front 140mm going in @ 60CFM
Side 200mm going in @ 110 CFM
Back 140mm going out @ 60CFM
radiator 120mm fans pushing out at @ 70CFM x3
top of the case 200mm fans pushing air out @ 110CFM x2 (not shown in picture)

Temps:

CPU:
Idle: 40-50C
Load (LinX, Prime, IntelBurnTest): 75C peak after ~50mins
GPU:
~40C idle
Ran BF3 on all max (>.<) ~30 mins
50 / 57 C with CPU around 60C
The second GPU is always slightly hotter due to the loop setup.

I have a friend with a 920 at 4.0GHz, he's getting 36C idle and 50C load with a 6870 OC in the loop. He's using the Rasa kit block (the Raystorm I think).

The main things I'd change are the CPU block (EK Supreme HF or one of the other highly rated blocks) and maybe add a rad if you can.

Neither are necessary as your temps are fine, I'd be a little concerned on the 75C for the CPU on water.

woah that's a pretty big difference there... wonder why, what about my gpu temps?
I don't know where I would put the second rad tho, I want to keep it all inside.

Could be the thermal paste, try re-applying (use a little less this time). Your GPU temps aren't too bad. My friend sees 45C on his GPU under load. I never go above 42C on my 5970 under load biggrin.gif

I'm not sure if you can add any more internally...

yeah, dunno what kind of temps your going for and why, but that looks just fine friend. Curious what kind of liquids you have in your loop as your run all that lighting. What kind of biocide you use and hows the water looking after 9 months?

I dont think changing your cpu block is necessary. You would see maybe a 2-3 degree difference tops.

You might consider running the two GPUs in parallel, they might increase in temp by ~1-2C but will both have the same temperature, and it will increase the flow through the CPU block, which could help lower temps there. Other than that, I'd definitely take a look at how your thermal paste looks on the CPU, it's possible it wasn't a great mount to begin with.
