My GPU isn't cooled properly? Defective pump?

[dFine]

Hello LTT Forum!

 

Yesterday i finally got my GPU cooler home. An EK-VGA Supremacy (Copper Acetal), for my MSI GTC960 2GB.

 

I wanted to install it into my existing loop. In 2013 i bought a complete XSPC kit, 240mm.
It includes pump build into the resovoir, a radiator, a cpu block and tubing. However this setup is changed a little.

 

My setup is as follows:

Asrock Z97-M Anniversary

Intel i5 4460

12GB Kingston DDR3 memory

MSI GTX960 2GB Edition

 

CPU Block: XSPC RayStorm

Resovoir: XSPC X2O 750 DUAL BAY RESERVOIR PUMP V4

Radiator: XSPC EX240 240mm

GPU Block: EK VGA Supremacy (Cobber Acetal)

Tubing: Primochill Primoflex Advanced LRT

 

- I hope thats all info needed,

Now, the problem is, that the GPU is not cooled properly. It reaches sky-high degress in a matter of seconds if in use.
The block is seated correctly, and the therman compund is also applied correctly (rice corn) - I have also tried re-applying this.

 

The odd thing is, the CPU is cooled correctly, and is running at a smooth 34C in idle.

 

Some odd thing i noticed was, when i first made the loop, it looked like the pump wasnt powerful enough. It wound not push bubbles through the blocks.

The thing i did, was to remake the loop. Flush everything with demineralized water, changing how the loop is connected (From: Pump -> Rad -> GPU -> CPU To: Pump -> Rad -> CPU -> GPU).

 

So now the situation is, that the water is pushed through - It looks like at "good speeds" since bubbles fly quickly through the tubing. However, the GPU is still hitting 80+ temperatures in a matter of seconds if you just move a window around. However, if you stop moving anything around, and the GPU goes idle - The temperatures drops fairly quickly down to about 45C.

 

I am hoping some of you have any ideas what might be causing this issue - And maybe even a possible fix.

There is so many price matching issues with your build i don't even.

Might be, this system is build over several years, and not bought and build on the same day.

 

The watercooling is from 2013, mobo/cpu is from 2015, GFX is from 2016 - And i just got some money on hand, and thought i would watercool the GPU.

 

Since its a universal GPU block, i can use it on future graphic-cards aswell, if i am upgrading in the future.

[Xenift]

Universal? Then that is okay i guess.

But money should be really spent on something more deserving, like a unlocked CPU.

Even if this is build over the years, there is little to no planning to it for example having a 2GB card instead of a regular 4GB card.

 

It's my opinion i guess so do what flows your way best.

Did you watercool a 960?

Yes i did.

 

You might not think thats a great idea, since its a very inexpensive card - And it would have made more sense to just buy a better graphics card.

 

But the GPU and the waterblock is bought at seperate times.

 

Actually i watercooled it most for the looks, as i like the look of watercooled systems.

240 rad for a GPU and CPU is whats wrong.

I would have thought that would be enough. But that still doesnt explain my issue.

Do you want to try to cool the GPU first?

Tried that, same result

Is the vram also covered by the block?

on the MSI card, there is already heatsinks installed on the card underneath the stockcooler

For a non_K SKU and a GTX 960, 240mm rad is enough.

Since you're sure water is flowing in the loop. And the CPU is cooling properly. The only explanation would be a bad contact of the GPU block and the GPU die, for some reason. That's the area to investigate.

If you still have the stock Intel cooler. Try to mount it to the CPU. So the loop only cools the GPU to see what happens.

Which standoffs did you use when you mounted the EK VGA Supremancy?  The one for the bare die or the one for the integrated heat spreader?
