*** HELP water cooling with generic water block

[Roman Mandeleil]

Hey Fellows,

I am trying to cool R9 280x like that:

I see that the effect is minor and very fast the temperature
is going up over 90C. Has anybody succeed to
cool with that kind block ?

Thanks in advance
Roman

the problem is the lack of ram and vrm cooling with that blook. usually water blocks for a gpu cover the ram and vrms. that one does neither. you're going to have to get some ram heatsinks and a fan to move air over the card to keep that thing cool.

that or use a different waterblook... one made for your gpu.

That's wrong direction,
I am getting notification
about the main chip only.

The vram can be cooled
by passive coolers, and
it takes a lot of time to
it to get hot.

well if your only getting temp warnings from the gpu, then i'd say you have poor contact. Did you use thermal paste? is it applied correctly? clearly there is a heat transfer issue.

Yeah I used a thermal paste,
even tried different quantities
of the past, also tried to put
some piece of metal between
the block and the chip. No success. 🙁

Ok. well i'm gonna tell you something i haven't said in 2 years on this site.

I'm not qualified to help you over the net. This is the type of problem i fear i'd probably have to have in front of me and a weekend to work through. There are dozens of things that could be happening in a custom loop, that all need to be checked out.

here are some thoughts

1) could be poor water flow. Did you flush the radiator propperly? Are you sure your pump works right? All the air out of the lines? no air in the block gumming things up?
2) the block doesn't make good contact with the chip, perhaps it has a bad contact surface that needs to be smoothed.
3) my original thought could be right, and your overheating parts that need good airflow. try using a fan and blow air across the board, see if temps come down.

Thanks a lot for you help ,
but unfortunately I've tried
all of this and I don't see any
cooling.

Is there anybody who actually
tried it with the generic water block ?

 

[Roman Mandeleil]

Any body else ?
Really need help on this.

🙁 sorry i can't help. figured you'd have all the bases covered, since the mod you're doing isn't for a beginner. Since you tried blowing air on the board, I am of the mind there is a water flow issue caused by air, debris or a bad pump.

~Check the temp of the water in your reservoir. If it's basically room temp then we can eliminate the radiator from the issue (if it's hot then we've got a problem with the rad you're using or the fan)... next i would test the pump and make sure it's actually moving water in the system (disconnect the whole rig, run the pump to pump water from one basin of water to another. you can check if it has a strong water-flow this way). Finally i would blow water through your block to make sure water can flow through it... if after all of this, you still have issues i'd say it's an issue with the heat transfer from the gpu to the block that is the issue.

This does sound like a flow issue, not necessarily a block contact issue, but I do not want to rule that out. What block is that being used? What pump? What is the water flow? What other loop components? Is there an airlock? Are CPU temps normal or also high?

Found the solution:
inserted copper disc
between water block
and the chip, it seems
to be stable.

 

[ingtar33]

in short the custom mounting bracket wasn't giving you good contact between the block and chip.

glad you found a solution 😀 i was wondering if you had fixed it.

 

[Roman Mandeleil]

I think it's not a contact
(I've double checked that)
but a metal quality , I suspect
that the water block
is not really made of
copper

 

[ingtar33]

urk... is your rad copper or aluminum? you'll need to find before you start to have a problem in your loop.
