Hi all,

so yer i was just basically wondering if the below temps of my respective components at the listed speeds (stock for CPU) under Load, (tested with Uni-engine Heaven and Prime 95 respectively, thanks:

Radeon 5970 both Cores at 725Mhz RAM at 1000Mhz

Load Temperature was Max of 31c on GPU1

Load Temperature was Max of 30c on GPU2

CPU temp was 38c Max on the highest core at stock 3.184Ghz

so yer please let me know guys and gals!


thx

Martin

Sweet temps, hope you are going to OC the 970 soon!
Also some pics would be nice

Peace

So are those temps well "safe" and "normal" and one other thing i know that LINX and Prime 95 will stress test my CPU, but how can i really stress test my radeon 5970 so i can see how far i can get it to over clock without making it too hot??????

thx Martin

It looks normal to me. But it's hard to say without knowing what program you used to test the temperatures and load, as well as how you're water cooling is set up.

How many radiators do you have? Could you specify a little?

[Martsmac]

OK well I have 1 360mm XSPC Radiator using 1 loop with my i7 970 CPU, Radeon 5970 in the loop and a single DDC pump with Tygon tubing , I use prime 95 to stress test the CPU and use Realtemp gt to test my CPU temps,
to test my Radeon 5970 temps I'm currently using the latest version of GPU-Z AND TO BENCH TEST / STRESS TEST THE GPU IM currently using Uniengine Heaven 2.5 and FurMark scores and temps I posted above are from uniengine, prime 95 and realtemp and gpu - z

[mihapiha]

Wow. Then your temperatures are really good. A single 360 radiator for a Core i7 970 + two graphic cards? Awesome temperatures right there...

[Martsmac]

Sweet but yer at the mo the 970 is only running at stock clocks at a later date i intend to try and push it to at least 4.0Ghz, (oh by the way whats the max recommended "safe" temperature for the I7 970???), also i just wanted to make sure you were aware that i only have the 1 graphics card, I mean yes it's a DUAL GPU CARD but it is just the one PCB.

the CPU's max temperature is 102°C on the cores before the CPU shuts down the PC, the save temperature is at about 80°C on the cores. I'd wouldn't put it that high though either because you have two graphic cards hanging in the same loop. Usually water coolings can handle about 1.4 - 1.45V for 24/7 usage, but in your case I'd not go beyond 1.3V to tell you the truth. After all the radiator is pretty much at it's limit as it is. You need more radiators for that kind of a setup or hang the CPU on another loop to overclock it past the performance of an air cooler.

The thing is that, while prime testing it will look fine and your CPU won't surpass 80°C, but you have to understand that the graphic cards will raise the water temperature. So if you're gaming and there is a game with heavy load on both you should leave it at lower clocks, otherwise it could happen that you damage the CPU.

If you can, measure the temperature of your water. What settings you use isn't really important, important is only that you take those measurements at full load. Meaning with Furmark and Prime95 running. If the temperature of the water surpasses 40°C you need more radiators. To tell you the truth, I'm not even sure if you can overclock with a single 360 radiator and such a setup. If you don't have some powerful fans on that radiator I'm afraid that the water temperature may surpass 40°C as it is.

Yer my initial plan when i built the water-cooled system (the first I've ever put together) was to have two loops and use 1 for the GPU and one for the CPU which i still intend to do , it was just that I killed one of the two pumps that i bought on arrival (not sure how but i had removed the pump top to install it in my dual bay res, which also has to separate res sections hence I'm future proofed for 2 loops which is nice), only reason I'm sill only going with one Rad is that i cannot fit another radiator into my CM ATCS 840 case without modding It which i don't have the time to do really, Ideally i would like a minimum of 2 360mm radiators but have had trouble locating a case beefy enough to hold em again without mods!

Oh when it comes to measuring the water temp, could i do that by just measuring it in the reservoir???

For GPU Temperature testing, use either OCCT's GPU test, Furmark, or, if you don't wanna use things that "dangerous" as some people call them:

Metro 2033 @ the highest settings continuous loop for about 10 runs will heat'em up nicely. Heaven 2.1 @ 1080p or higher with 8xAA 16xAF Extreme Tessellation (That'll make'em crawl cuz the 5xxx-series AMD cards are not that great at Tessellation) will also see some high temps. 3DMark Vantage using a continuous loop of GPU Test 2 would also get you some good ideas as to what your load temps are, if you own the Advanced Version, set to your screen resolution, and set all the other stuff to "extreme" settings.

Here's a list of what settings are imposed if you actually have a monitor capable of doing the "Extreme" preset, which is 1920x1200 on Vantage:

Default settings used: Yes
Preset: Extreme
Width: 1920
Height: 1200
MSAA: 4
Texture Filtering: Anisotropic
Anisotropy: 16
Texture Quality: Extreme
Shader Quality: Extreme
Shadow Shader Quality: Extreme
Shadow Resolution Quality: Extreme
Post Processing Scale: 1:2
PPU Disabled: false
PPU Used: true
Disable Bloom: false
Disable Streaks: false
Disable Anamorphic Flare: false
Disable Lens Flare: false
Disable Lenticular Halo: false
Disable Motion Blur: false
Disable DOF: false
Disable Fog: false
Disable Color Noise: false
Flush On Low FPS: false
Fixed Framerate: false

That'll make'em about as toasty as they're gonna get if you leave it on a loop for about 5-10 runs.

Measuring water temperatures within the reservoir is just fine.
I hope I've given you the information you were looking for though. Besides: The CPU doesn't need a 360 radiator on it's own. Of course that would be ideal, but a smaller radiator would be also fine. The important thing is only that the load on the graphic cards doesn't influence the CPU's temperatures. My CPU temperatures fell 10°C because I used two loops. I mean that says it all I believe.

Depending on where you live you could invest some money in a new case which would fit all the watercooling equipment that you need or settle for an external unit. My personal preference for the external unit is the WaterCool Mora-3 radiator. I used it to cool 4 GPUs. It was just unbelievably powerful even with only 700 rpm fans. The Koolance ERM-3K4UCU should be mentioned at this point too. Case-wise MountainMods (US) or LittleDevil case (EU) can't be beaten in my mind if you're water cooling everything, and need tons of room for radiators.

So just a quick update i just ran that occt program whilst monitoring my in resevoir water temps for an hour run and the water temp NEVER exceeded 33.8 degrees celcius, bear in mind however that this was only with the GPU'S outputting heat, what is the best way to stress test both the GPU'S AND the CPU at the same time???? would running Prime 95 AND occt at the same time work???

[mihapiha]

To my knowledge the best for stress testing is prime95 + Furmark. At the same time of course. Keep in mind that the 40°C water temperature doesn't mean instant death of hardware equipment, but it is a common indication that additional radiators are needed. I know of a few people who run @ 45°C water temperatures and power up only the fans if needed. But if you intend on overclocking you'd be better off if you used 40°C or less water temperature while the rig is under full load. The cooler the rig the less voltage it needs to be stable, and the more stable it is in the end...

After all summer is coming and because of that your water temperature will go up a few degrees. So it's up to you: Either a bigger and better radiator or lower overclock.
Personally I believe you should only check what is the max which could happen now and try to stay with Furmark running under 80°C with the CPU temperature.

If you monitor carefully you should be fine even if the water temperature reaches for arguments sake 44°C or something, since the amount of load and heat you generate with Furmark + Prime95 pretty much can not be copied in a gaming type situation... So your rig - if it's not meant for folding - should be fine at that point too. Just keep an eye on as many temperatures as you can - including the water temperatures - and take your time with the overclocking and testing....

Intel speed burn + furmark

key thing with this rig is test CF games wont heat all the gpus so hot they fry the cpu by accident.

So games that run great with CF like the source engine with vsync off are a good test.

Just tested with both Furmark (MultiGPU version) AND Prime 95 running (at the same time) and the temps that i have to report are a Max of 40 celcius on 1 of the CPU cores, and a max of 33 celcius on the GPU according to Catalyst Control Centre Temp sensor.


Any Good????

Martin

Also when i stopped Benching the GP's (I.e. stopped running furmark) my temps on the cpu dropped to 37 -38 degrees on the hottest cpu core, eventually I intend to move to a dual loop setup, and also a completely new build when sandy bridge EX comes out on the 2011 socket, but for now im only doing the one loop, does any body have any thoughts on the quick interconnects you can buy now at all?
