6800 Ultra temp questions.

[Kosmic71]

Yo guys, I just removed the stock cooler on my eVGA 6800 Ultra
and putted a water block. My temp at idle is 55C and 61C on load (BF2 3hrs).
Stupid me I didn't take note of the temp with the original
cooler.

I find that 55C is kinda high for water cooling, don't you guys
agree? might be the block that don't make perfect contact, I don't
know.

Here's my rig spec (water cooling loop):

3500+ Clawhammer oced to 2.6 at stock volatge (1.456v) on a
6002-64 sweftech waterblock.

eVGA 6800 Ultra stock speed on a N20 Gun waterblock.

All 1/2" ID tubbings, Swiftech pump MCP650, HW Black ice blue
Xetrem-2 rad. I used AS5 on the gpu and ram.

Now, any info on that 6800 Ultra temp would be appreciated.

Thanks :D

Here's a few pics of my water system and my new video card
water block.

Thats not bad at all for an ultra but going over 65 is to high. 55-65 is normal oced temps with water.

[chunkylover77]

That is a real nice system. Did you build that yourself?

[Kosmic71]

Thanks man. :D Yes, I build it myself click external water cooling box in my sig.

So, running 61C on load without been oced yet is too high?

mmmmh! I will have to disassemble everything to give it a look. That suck. :mad:

[xtatdsm]

well I am not too sure, but those temps seem a bit high for water.

I get 42 idle and 47 max load (D3D) with my BFG ultra OC to (455/1.17)

room temp is about 24C and water temp is 25C-26C (2x dual heatercores) that's with preshot OC to 4.0 too.

I'd say that's pretty high for an eVGA 6800 Ultra, but again, I saw lower temps on my 6800 GT AGP compared to the PCI-e version. I switched to the copper heatsinks provided by them, and it dropped it more than watercooling probably could have. I even tried the Arctic Cooling NV Silencer 5, and it was just poor as can be... 75c under load, 53c idle.

Doesn't suprise me with those temps actually. I have a eVGA 6800 GT and my load temps unoverclocked are in high 80-90 C range.

[MrBean]

Thats a tad high...I had 2x eVGA 6800U's in SLi, and with 6693 drivers, watercooled temps were idle 42 deg C, full-load around 47-50deg C.

That is with high ambient temps, Durban, South Africa, and only 10mm od 8mm id tubing, 3x 120mm Aquacool rad, and Eheim HTTPS 12V pump.

Far weaker than your setup. How is your seating of the block on the GPU? Enough clamping pressure? Not too much AS?

Few small things to check, but worth it.

Also, you could run a straight-edge over the spacer plate surrounding the gpu core, just to make sure the core is not below the surface of the spacer, then it would mean bad/no contact - I guess this must be your issue.

What drivers though?

[Kosmic71]

mmmh! I'm at 55C idle and 86C max temp (RivaTuner monitoring) with 3Dmark03 at 400/1100 (stock).

I'm wondering if its my ClawHammer that send dang hot water to the gpu or its a bad installation from my part? :mad:

Driver 77.30

Edit: I few runs with 3Dmark03

2.6Ghz - 400/1100 - 12840 - 86C max
2.6Ghz - 405/1105 - 12935 - 85C max
2.6Ghz - 410/1110 - 13093 - 86C max
2.6Ghz - 415/1116 - 13179 - 88C max
2.6Ghz - 420/1121 - 13304 - 88C max
2.6Ghz - 425/1126 - 13347 - 89C max

I stopped there because I don't want to get over 90C.

Doesn't look good right?

ur gpu temps are WAY high.. its possible due to the way the gpu block works, that its not making god contact with the gpu itself. im guessing ur memory chips are slightly high or that the block had a slight manufacturing error. I suggest getting some high grit sand paper and sanding the memory pads down a bit. 800-1000 grit would work well, as it would not scratch up the surface of the coper and would take very small amounts of material off at a time.

[Kosmic71]

Didn't ppl say that N2O Gun block rocked? :p:

Anyway, I will disassemble and give it a look. Im sure that my ClawHammer in the loop doesn't help either.

Temps are definitely high. I'm on the 6800GT overclocked to 431 as in the sig, and it idles at 39C and loads at 43C.
