Fractal R2 watercooled [pics inside]

A pump shouldn't get that hot to melt electrical tape. I know DDC's typically run a little warm compared to D5's, but even then, that's scary. I know a lot of people that use heatsinks for the bottom of their DDC's and then elevate the mount via standoffs and screws.

swiftech had an option for their pumps too :/

This is just one example, but what I was talking about. Swiftech does have something almost identical.

 

[Lutfij]

ay, ye be right matey!

 

[rubix_1011]

You think I'd lie to you guys?

 

[toolmaker_03]

+ 1 for NO

 

[Lutfij]

You think I'd lie to you guys?

:lol: nay matey!

The Gpu core temps are 55c and the other gpu 52c.

Looking at Laing specifications the pump has maximum system temperature 60c.

I guess I'm still on the safe side?

 

[rubix_1011]

Seems about 10C high to me.

 

[grandpatzer]

Seems about 10C high to me.

why is it bad to have 55c?

 

[rubix_1011]

My GPUs at load never exceed 45C at load for extended periods of time (4-5 hours) using GPU processing in BOINC @100%. This isn't as rough as Furmark or other benching software, but it's considerably more than most games push cards.

 

[grandpatzer]

I think Crysis 2 with DX11 texture or BF3 can push harder then furmark

 

[rubix_1011]

My point is that you still shouldn't see temps that high. If your GPUs are pushing 50% or 100%, they really shouldn't be more than 1-2C difference in temps; you aren't increasing the heat load in watts by a significant amount that would cause a difference of 10C.

 

[grandpatzer]

Ah ok I got it.

I think the only component that can take damage is the pump then?
I can't see how 55c harms the tubing or any other part of watercooling?

I'ts a 10w Laing DDC-1t that I'm running at 63% so it should be about 7.5volts or 6.3watts I think.

 

[toolmaker_03]

i dont think that is what he is trying to say, the problem is the temps are too high, and the way that the blocks are installed might be the problem. I have ugly computers and no air flow through the case, it is basically a passive system. not to mention the fact that the video cards I have, run hot, the 8800 ultra under air cooling ran at idol 135 F under water cooling 113 F. so there is defiantly something wrong here, but what it is I can't say for shore, without knowing how you installed the block and with what material you used for that perpose.

 

[Lutfij]

and with what material you used for that perpose.

i had to giggle at this

 

[grandpatzer]

well on air it would be 80c+, so 55c is atleast 25c less compared to air.

Considering the other GPU is 52c I would think the water temperature is 52c or less, so the pump should be safe.

 

[toolmaker_03]

well your right, if that is what it is on air, then that is about the best you will get on water about 25 F difference, that is a hot card, what is it again?

 

[grandpatzer]

AMD 7970

 

[toolmaker_03]

so you're talking about load temps then, and not at idol. and the card stabilizes at that temp, well that is pretty good.

 

[Lutfij]

no, the temps rubix was mentioning is that the temps between both cards should be a degree of two each other and not what grand is seeing is also high.

 

[rubix_1011]

Water temp isn't the same as the reported GPU or CPU temps.

 

[Lutfij]

true

 

[rubix_1011]

It was mainly to address the concerns here:

Considering the other GPU is 52c I would think the water temperature is 52c or less, so the pump should be safe.

 

[grandpatzer]

well it stabilized at 54c and 52c so I guess the cards are only 2c different then?

So what is the water temp, I would imagine it being lower then 52c or same so 52c.
It can't be higher then 52c because then the GPU would have to be more then 52c.
