Watercooling Temperature Issues

[lonewolf1508]

Hi,

I had been using the XSPC Raystorm rs240 kit for past two years and decided to add a GPU block and 2 additional 120 radiators to the loop but i'm getting high gpu temps with my new setup. I've listed my setup below and the temps i'm getting, please advise me on troubleshooting this.

CPU : i5 2500k at 1.35V at 4.8GHz
GPU: MSI 970 4G Gaming overclocked

Pump/Res : XSPC D5 Vario Res/Pump Combo
CPU Block: XSPC Raystorm
GPU Block: EKWB 970 TF5
240mm Radiator: XSPC RS240
2 x 120mm Radiators : Alphacool NexXxoS ST30
Fans: Corsair SP120 Quiet Pull
Tubing: Roughly 2 metres of 19/13mm tubing

Setup as follows: Pump/Res > 240 Rad (Top of case) > CPU > 120 Rad (Rear of case) > GPU > 120 Rad (Bottom of case) > Pump/Res

Idle Temps:
CPU 30 degrees
GPU 27 degrees

Load Temps:
CPU 60 degrees
GPU 75 degrees

Any thoughts, are my temperatures normal for my setup or should i redo the loop and re-seat the GPU block?

Thanks

CPU seems fine but that GPU temp is super wrong.

I'd redo the block.

i assume you have overclocks... looks about right.
if no overclock then you may have air in the gpu block

Put the pump at max speed and start tilting the case from side to side to work any trapped air round to the res.

Keep an eye on your water level in your res.

As above there lots of potential for air pockets. I've not properly water cooled for a while but do you have some sort flow indicator in the loop so you can see how the pumps performing. I always found them a useful diagnostic device in longer loops.

You say load temps? Loads on what? Is your CPU load from Prime95 or IBT? If so its very good, however your GPU temp is appalling. Shouldn't be that high under water.
