Disappointed in temperatures.

[Draceus]

So, built my first Water cooling loop yesterday and was really excited to get to see the low temperatures on the GPU I was hoping for. Problem is, the temp goes all the way up to 70 c on load on the GPU... Its allot higher than I first anticipated building this loop.

I'm not sure I got 100% of the air out of the system yet, probably a little bit left, but does that effect the cooling more than a few degrees? 

Running the following components:

R9 290 cooled by EK-FC R9-290X- Acetal + EK-FC R9-290X Backplate
i7 4770k cooled by EK-Supremacy - Acetal
1000w platinum PSU
Alphacool NexXxoS UT60 360mm Triple Radiator with 3x Noctua NF-P12 1300

The reservoir is directly above the pump feeding it with water, from the pump to the GPU, GPU to CPU, CPU to Radiator, Radiator back to reservoir... All connected with compression fittings and 19/13 mm hose.

probably a bad mount.

[Draceus]

Talking about the gpu mount? 

Have mounted allot of gpu coolers in the past, no waterblocks but I followed the instructions precisely

yeah well you can follow the instructions as good as you want

maybe not enough/too much thermal paste, screws not tight enough etc.

 

Edit: Also, please use the quote function

So you would recommend me reinstalling the GPU waterblock? What kind of temps should I expect if it was working as intentional?

it should be at like 50°C under full load.

 

You could check some other things first:

Are the fans spinning?

How are the cpu temps?

Pump running at a good speed, check the flow rate of the water?!

[SpyRosL]

Draceus

Definitely a bad mounting on the gpu.What's the temps on the cpu on full load? Is it overclocked?

The 290 should run at 45-50C at full load.

My cpu is at like 80c full load, 4.2 no voltage increase... Sorry if forgot to add what pump Im using, running with the alphacool D5 on speed setting 2. Fans are spinning for sure

woah 80°C sucks as well. Try the pump at like 4 or 5. and turn up the fans. if that doesnt help remount both. What thermal paste are you using?

Using the one that was included, might have been stupid but I thought I had some good left home, turns out I dident and was to impatient so just used what I had.

Let me try for a sec to turn pump and fans to max, will report back with results

Woah,something is definitely wrong here.

Either the mounting for both cpu and gpu is bad or the fans are not blowing air in the radiator properly. But you have a ''leak'' somewhere.

[Draceus]

Ok so CPU temp is still like 70c when I max the pump and the fans. GPU is even idle on 40c

[Draceus]

 Would you say the nocuta fans are enough? 3 of them pushing air from the outside of the case into the radiator.

 

edit: Its defiantly not air in the system?

Can you give a pic of you airflow layout in the case and where everything is mounted?

Pretty sure its not the air.

CPU is fine at 70° but still not really great.

 

Re-Mount that gpublock for sure.

Hmm.

Let it there for now,get a good thermal paste(arctic silver 5) and re-mount cpu and gpu.That's what i would do.

Gonna go remount the cpu and gpu block, will take pictures of everything and post them back here when Im done

yeah do that. make sure to clean the chip correctly, apply right amount of thermal paste, tighten screws good and dont spill any water over your stuff.

You have to remember the 290x produces lots of heat normally so more cooling would be needed to drop those temperatures. Now there could be air in the GPU's water block and or a bad mount of the GPU's waterblock. What is the CPU's temperature on load?

[Draceus]

Ok, so I phoned a mate up and he had some arctic silver 5 as recommended earlier by Spyrosl.

Coming back with load temps soon

[Draceus]

10 min of testing after remounting.

GPU 56c and slowly rising.

CPU 80c

I see lots of air bubbles in the system, very small ones but lots of them... How much would this affect the overall performance? 

[Leonard]

It would depend on where the air is trapped. If it is trapped in the CPU's block which is quite unlikely as CPU blocks don't have much restriction or the GPU's block or radiator, which is highly likely, it would affect it quite a bit.

 

What pump are you using? D5 i suspect.

Yes its the D5

[Leonard]

Yes its the D5

Then you have more than enough flow and pressure for your loop. Have you tilted and lightly shook your PC while the pump is running to help dislodge the air? 

 

You would want to tilt the case to the opposite side or where the fittings are on the radiator so all the air goes to the out let of the radiator and then it is sent to the reservoir.

I have shaken and turned the case all over the place.

Right now the case is stood on its front with full speed on the pump.

As you see on the pic that causes the fittings on the radiator to be on the top
