5870 and 5830 water cooled.

My 7850 runs at 63C, a few degrees lower during winter. Fun times 

BGFMiner labels devices like that, I guess OCL = OpenCL device.

my 5830, before fan/sink clean and new paste = 75C @ 90% fan
             after                                           = 65C @ 30% fan

ambient around 25C.

I guess it was worth it

just using some ATI 5970s

using bfgminer on ubuntu, i think it might be labeling them as OCL because of the AMD drivers i am using maybe? not sure really.

All i know is it's working and stable, so it can call em UFOs for all i care

Hmm i think you are going to have some hard times in summer...

OCL what kind of hardware is that?

--------------------------------------------------------------------------------

finally got my cards semi-stable, need to add the 4th, then i'll try to maybe OC a bit

My rig is 3x 7950s, the temps are usually ~84 and then the one in the middle is like 90 because it receives less air flow.

Running non-stop for 2 days

When mining litecoins my 3 stacked cards on gpu run upto 76c with outside temperature reaching 30.
With bitcoin downclocked its usually 69, but fans are on really low settings then.

One of my fans start to make noises, I fixed it but, I started thinking... why not replace the original fans and store them, so we can sell the card later on when we no longer use it! and put two Arctic cooling F PWM F8 or F9 CO fans screwed to the heatsink directly? these are designed for 24/7 operation.

I will try this in a couple of days and post pics, the fans are 4 wire, PWM with speed sensor, and, removing the plastic cover, will not be too difficult to bolt them to the heat-sink at all, I will use F8 for 78xx cards and F9 for 79xx cards (F9 are 9,2 mm, more CFM )

Haha zipties ftw 

That poll needs tighter values...

Between 70c-90c = 158F-194F

30C is THE-UNICORN
35C is THE-GUY-PAYED-TO-GROOM-THE-UNICORN
40C is THE-GUY-WHO-RIDES-A-UNICORN-TO-WORK
45C is A-FREAKING-LIAR
50C is DAMN-NEAR-A-FANTASY
55C is PERFECT
60C is GREAT
65C is IDEAL *** (My temps)
70C is NORMAL *** (My temps)
75C is OK
80C is WARM
85C is HOT
90C is NEAR-LIMIT
95C is AT-LIMIT
100C is SOON-TO-BE-DEAD
105C is DEAD

My temps, as reported by the GPU... (In order)
75, 75, 74, 73, 69, 69, 69, 69, 65, 63, 61, 61, 61, 61, 61, 61, 61, 61, 61, 61, 61, 61, 61, 60

Actual temp of all of them... (Majority of the day) These match the above cards ordered.
67, 67, 67, 66, 67, 67, 67, 62, 66, 66, 67, 67, 66, 65, 65, 65, 65, 65, 65, 65, 65, 65, 65, 66

Ambient room temp being 29c (86F) {outside air, I live in Florida, it is 25c(77F) at night, and humid.}
Nights the cards run about 2c-3c cooler.

This is "running for days" temps. The cards do NOT report the actual temperature. They are "ballpark" at best. They are not calibrated or high-quality temperature sensors. The most important thing you get from them, is "increase over ambient", once you know the "ambient" temperature of the running card. The higher the temp, the more inaccurate the sensor, but it is consistently inaccurate.

I wish someone made a temp-program that let you "calibrate" the output of the sensors. (Even if it only shows correctly in that program).

I write the "ambient" and "running" temp on each card, and give them an ID, to tell when they are drifting into dangerous grounds. (Along with a cheat-sheet, at my keyboard.)

P.S. These are all 7970 reference-design (HIS series {the hot ones}), and PowerColor (The cheap 2-fan models {the cooler ones})

When the stock fan dies you just remove it and put a 80 or 120mm case fan on it with zipties lol

Mostly 80s and 90s. I have a couple 6950s that chill out around 102 and dont seem to mind.

They might be worth $30 each 30 months from now so whatever...

PSA: if you're mining bitcoins, you can lower your temps significantly by lowering your memory clocks. Your mining speed will not be affected. In some cases, you will actually gain speed.

Why would I put my my $400 GPU at risk of overheating, just to save a $5 fan from burning out quicker? Crank those fans for as long as they'll go, and you can always replace them later. It's a lot more expensive to replace a GPU.

Do you guys think that it is better to sacrifice a few temp degrees to lower the fan speed?

I dont know why but i have the impression that my fan is much more vulnerable than my card.

So I guess I am killing my poor 6870's

first is at 965Mhz slight voltage underclocke to 1.104

95
98
101

The second is at 945 same voltage

95
96
94


Running 24/7 flawlessly stable even at those temps.

Ill take the advice and down clock them till I get the chance to move it to the AC Cooled server room.


edit
dropped to 850Mhz, voltage at 1.000

82
84
88

and

85
83
81


Stupid blower card fan higher then 48% get's loud. past 60% is brutal.

hehehe yeah!, same here with my 7850 when I was in windows, If I lower the ram below 700 Mhz I start to see all kind of crappy blocky shit on the screen heehe.
that didn't happens in linux thought, also in linux , I get an extra 25MH per card at same settings and speeds.
