My 280 arrives today, and I have the EVGA Hydro Copper 16 Waterblock!

[Section8]

Yeah you have it correct right side in and left side out no matter the barb position. Now lets see some load temp

[Talonman]

My cover is on the PC, and I have moved my fan up to 100%.
I want to know the best the fan can do before I go water cooled.
I'm trying to give it every advantage, to see how much my block can actually lower my temps.

Current basement temp is 70.3F

I ran 3DMark06 at default settings, and kept Precission open taking a GPU temp reading after each test completed.

Temp after Return to Proxycon: 59C

Temp after Firefly Forest: 59C

Temp after CPU1 test: 51C

Temp after CPU test2: 49C

Temp after Canyon Flight 59C

Temp after Deep Freeze: 60c

Not too bad...

3DMark06 on water... Current basement temp: 71.6F

I kept Precission's on screen display active, and watched the screen like a halk recording the highest temp I reached during each test.

3DMark06 at default settings:

Temp during Return to Proxycon: 43C (16C cooler!)

Temp during Firefly Forest: 44C (15C cooler!)

Temp during CPU1 test: 39C (12C cooler!)

Temp during CPU test2: 39C (10C cooler!)

Temp during Canyon Flight 44C (15C cooler!)

Temp during Deep Freeze: 44C (15C cooler!)

I have to say that I am impressed getting up to 15C cooler temps, with no fan noise under load. I had to run the fan at 100% to generate my first set of numbers.

I am thinking that keeping my loaded temps below 50C means I'm doing pritty good.

Another thing was when I was re-filling my loop, my flow still seemed plenty strong jetting my water through the lines. I was consirned about having enouigh flow for the 3 blocks. I now think it's a non-issue.
It still looked plenty strong to me.

If the question is asked if you can cool an OC Q6600, a 280, and NB all on a Thermochill PA 120.3, my answer would be yes...

It might also be said that as expected, the full block shines under load, rather than just at idle on temperature reduction.

The 4C cooler temp is nice at idle, but 15C less under load stands out to me as more valuable to the OC'er...

[Talonman]

Are you gonna watercool the PWM/mosfets?

Nope. I am a 1 loop guy, and don't want the extra resistance on my pump.

[JacobF]

Nice How about OC'ing?

[Talonman]

Very soon...

30 minutes of Prime let me hit a high temp of 60C.



Before the block install 59C was my max on the same test...

I guess I can roll with that!!

[Talonman]

1 Hour of UT3, Max detail settings 1920x1200 and V-Sync on 57C.
I do have the UT3 Physx Mod installed too.

62 FPS non-VSync Mode
60 FPS with V-Sync on.

My new MAX temp for UT3 with the same settings is 44C.

That's 13C lower, than what I had with the fan set to 100%.

[Talonman]

This will be my last report on the stock air cooled 280.

For testing I went after the big dog of heat generation, Crysis.

I set it up at 1920x1200, all high except Object Quality was Medium. (4xAA no V-sync)

With the fan set to 100%, and playing from the beginning for 1 hour, 70C was the max I could get GPU temp up to.

I am convinced my card is functioning within normal paramaters. (Time to mod it!)

I am taking it back out, and will be beginning my block install shortly.

Using the same settings, but only for about 30 minutes, 48C looks to be about the most heat Crysis will now generate...

This is right after exiting the game, and the highest GPU temp I have been able to generate since the install:



That's a Mighty 22C lower than my air test playing Crysis.

How does this performance sit with you boy's?

I think it rather ROCKS myself!


The End!

[Yeknom]

OC results! Please?

[Talonman]

OC results:

I used Precission's on screen display and recorded the highest temp I could hit during each test of Vantage.
Even if the temp only displayed for a micro-jiffie, it was recorded if it was a new high.
I kept upping my clock settings, to see how it would change my load temps.

Vantage using default settings:

280 Set To: -- Stock --- SC --- SSC --- FTW ---- HC
____________ Speed _ Speed _ Speed _ Speed _ Speed
Jane Nash ----- 44C ---- 45C -- 46C ---- 46C --- 47C

New Calico ---- 44C ---- 46C -- 46C ---- 47C --- 47C

Airplanes1 ----- 39C ---- 40C --- 41C --- 41C --- 41C

Airplanes2 ----- 42C ---- 42C --- 43C --- 43C --- 43C

Colors1 -------- 44C ---- 45C --- 45C --- 46C --- 46C

Colors2 -------- 43C ---- 44C --- 44C --- 45C --- 45C

Mountains ----- 45C ---- 46C --- 47C --- 47C --- 47C

Flags ---------- 42C --- 42C ---- 43C --- 43C --- 43C

Dots ---------- 42C ---- 43C --- 43C --- 43C --- 44C

Fog ----------- 46C ---- 47C --- 47C --- 47C --- 48C

Stock 280 scored= P12178 (602/2214)

280 to SC speed scored = P12567 (621/2268)

280 to SSC speed scored = P13013 (648/2322)

280 to FTW speed scored = P13586 (670/2430)

280 to HC speed scored = P13878 (691/2430)



I have not noticed any screen artifacts so far...

My 280's Vantage score set to HC speed:


I have added almost 2K on to my Vantage score just from the OC!

[Talonman]

Still running at HC speed, I ran 3DMark06.

45C was the highest temp it could generate on my GPU during the entire run.
Most of the time it ran around 40C.

[InputUsername]

Very, very nice results. Really tempts me to go water on my 280, air does a surprisingly good job though.

Congratulations on a gem of a card as well. ^^

[Talonman]

Thanks...

[Yeknom]

OC results not bad! Nice temps too

I bet you could go higher :P

[Talonman]

I decided to run Core=702MHz, Shaders=1512MHz, and Memory=1269MHz on my 280.

Still no artifacts, and Vantage is still not taking my GPU temp above 48C.

My new 'Keeper' settings gives me a 14K score in Vantage.


Once again, what my 280 scored using the default clock speeds:


A difference of 1,823 Vantage Points!
Ya gotta love the OC!

[Section8]

Temps look great. That block seems to be a great performer. Props to EVGA on their 1st in house design.

[septim]

hmm Talonman, i think you forgot to show us the internals of said water block...

other than that, it performed really well, nice temp drops, nice OC you got going...

I love the block. Understand too that keeping your 280 below 50C is not this blocks performance limit. One of the boys at the EVGA site is keeping his OC'ed 280's load temp below 40C. He is running in the 30's under load, but dosen't have a CPU in the same loop.

Keeping a OC'ed 280 below 50C is just my limit. Well, it is for now until my cold a$$ basement returnes to about 59F come winter! (Snicker...)
The RAD is really going to love it this year.

I am ok with this setup and my 1 loop. I think it should keep me out of trouble...

Thanks on the OC. I can't grumble too much. It was just a stocker...

I can't open mine...

But they have some E's inside.

Great score mate ! Nice colour of coolant. Keep going

[Talonman]

I think I'm done OC'ing my 280.

There can't be too much left in the card to give me with my Q6600.

I don't want to hurt the card in any way. This baby has to last me for a while!

I am just going to keep what I got out of her and grin.

She's about all the Xtreme I am willing to make her...

Core=702MHz, Shaders=1512MHz, and Memory=1269MHz producing 14K in Vantage with loaded temps under 50C is the end of the story for me.

[ShoNuff]

A difference of 1,823 Vantage Points!
Ya gotta love the OC!

Impressive clocks!
