On this used gpu running 2 wu's per gpu I was getting a temp of 80C. I was using the automatic adjustment for the fan which came in around a speed of 24% of max. When I turned it up to 40% using the manual control the temp dropped to 72%. This is my 2nd or 3rd used gpu. The prior ones I have had no trouble.

Should I turn it back in or give it a negative rating on ebay or just keep watching the temp over a few months time. It's a lot cheaper buying used than new and I hate to spend so much money. At the same time I don't want to be fussing around with returns or hassles.

I know that some of you guys have had a lot more experience with this sort of thing than I have. Any advice would be appreciated. Thanks in advance.

I was using the automatic adjustment for the fan.

Using Speedfan I surmise?
Why don't you configure all of the applicable fans in the system to work together? Tell the system which Fans are in it and actually used, then set max desired temperature per fan and in Speeds set minimum and maximum fan speeds, automatically variated.

Do set in Options that Delta value for fan speeds is 1, else it'll increment in swats of 10.

Configuring takes a bit of time, but if done to your own liking, and Speedfan set to start at system boot-up through a scheduled task, you don't have to adjust it much anymore by hand.

In my case I have set that the AUX fans and GPU fan work together, when the GPU goes over 60C the AUX fans start pulling in more cool air. Makes it that my AMD HD7870 maxes out at 65C before going down to the desired 60C again. All with max fan speeds of between 30 and 40%. Quite silent.

The only time I hear my fans are when playing a game like GTA V.

I just use the controls that come with Catalyst Control Center of amd. Nothing fancy or complex. The question is really is 80C ok for a "new" used fan?

80°C is to much for 24/7.
I wouldn`t go over 72°C.
When the card is build in reference design its normal but not good for crunching.
Lower temps will extend life.

Well I should have asked also: Is 40% of fan usage OK in order to get my temp down to 72C. I only use it about 24/7 for 3 months (coldest mos.) out of the year. For 2 months maybe 50% of the time and the rest of the year very little usage.

Its fine yes.
I have my GPU fans running at 50% all the time to get better temps.

Marle my fans run 50% min I set fans so 70% at 70 degrees and 100% for any temp higher than 70 this can happen on a hot day .

So first TURN THE FAN UP TO AT LEAST 50%

and second yes the temps your getting are ok even for a second hand GPU .

Did you clean the heat sink and fans before using it ? if not do so

The question is really is 80C ok for a "new" used fan?

No, that temperature isn't good for any fan, new or used.
Then either your system has a bad airflow in the case, something else is throwing out a lot of warm air into the case or the GPU itself has trouble with the cooling on it.

Is it a single fan videocard, a double fan, a triple fan, which brand is the videocard, does it have special cooling gadgets the brand added, e.g. like Sapphire Vapor-X?
How many fans does your case have?
Does that i7 CPU have water cooling and if not ever thought of getting that?
Taken all the dust-bunnies out of that system?

But really you ought to try Speedfan for a bit, it truly does work wonders. Even on systems that only run for part of the year. I have noticed that the Catalyst Control Center can read the temperature wrong, or doesn't follow its own setting of fan-speeds.

From what I have been able to find over the weeks since I built my rig is that AMD GPUs to tend to run very warm, especially under load. 80C is about the maximum temp for longevity, they will function up to 90C, I've proven that for myself. Mine run at around 78C at 99% load 55% fan speed. I am running 2, R9 280Xs.

My Sapphire HD6950, 4yrs old now, runs either 2 MB or 1 AP, it's currently at 90% load, 90C (control is automatic, not manual), & 43% fan speed. It's been that since I got it almost..

Yeah, I run with 2 gpu's which run at about 96% work load. I took care of those obvious questions eg. dust and cleanliness. The card has a double fan. It's a Sapphire. The case was a cheap one; it was my first build. The one after that one I used a much better case and fans and it runs cooler and quieter.

I got a lot of good advice here. I'll keep my eye on it and make sure the temp doesn't get any worse and increase my fan speed a bit. I already notified the seller that I'm not real happy seeing that 80C temp so I'm probably ok with ebay and claiming a refund if it doesn't work out in the next 30 days or so.

Thanks all.

OMG Merie some advise for you and others
Be careful leaving bad comments at places like Ebay and trashing some ones reputation when the product they bought works fine does what you expect .
Recently I have found out company's are fighting back and suing ppl that leave bad comments that are false at web sites like Ebay

Merle, you're running Windows. Just download Afterburner and set the fans to whatever speed you're comfortable-with.

It's the opposite of what it was back "in the old days" and the AMD cards are burning more electricity and getting hotter than the NVIDIA cards.

I've got four R9 270X cards (crunching another project) and every one of them has the fan manually adjusted faster using Afterburner. Not one would stay below 80C on "auto". That was in well-ventilated cases and in not-so-well ventilated cases.

Mine are XFX cards, so I really cannot comment super-specifically about yours, but I suspect the temperature targets are going to be about the same.

I don't think there is anything wrong with your hardware, but I would not run the cards 24/7 at 80C, so I think you need to find a way to increase the fan speed.

That's 100% of my advice. I don't even LIKE MSI Afterburner, but it's easy.

Glenn,
All I said was, as a message to the seller - the temp was 80C and asked him if the card was overclocked a lot and that I would have to watch it. If it turned out that within 30 days the temp started going to 90C or so I would have to give him a negative rating but I wouldn't say anything (bad mouthing). But thanks for the comment it's useful for everybody.
