GTX 470's @ 95c ?? Temps high ?

[Markfw]

OK, so I have 2 GTX 470's both stock voltage, but OC'ed to 700 mhz, and both in the same box, side cover off, both fans@80% (sound like hair driers) and one runs 85c, and the other 95c while running F@H (100% GPU load).

Sound too high ?

 

[happy medium]

Are they both the same model? Evga, Msi? They will vary depending on model.
I read somewhere that they will run cooler with the case closed due to air flow dependency.

95c seems a little warm even for gtx 470's. 85c seems right on the money.

 

[Markfw]

both exact clones, MSI

 

[Capt Caveman]

Mine tops out at 76c with the fan running 70% at standard speeds

 

[happy medium]

both exact clones, MSI

Same system ,same case, same airflow,same ambient temps in case?
All this stuff will change you gpu temps.

The only other thing I can think of is the stock voltage of the cards being binned differently.

One card could be .095v out of the box and the other 1.01v, that could make a difference. Just like a cpu's vid.

 

[Markfw]

same case obviously same airflow and ambients. I put the case cover on, and the temps went UP !

 

[CitanUzuki]

Its the top card right?

 

[Markfw]

And how would I know that ? I have not figured out how they determine that yet. Its GPU1 in egva precision (GPUZ reports the same temps)

Yes, way too high for a single card, but for SLI it's probably what is expected. Mine does not exceed 77-78*C at 66 percent fan speed. I have good airflow in my enclosure - Azza Solano. This may be part of the reason. My CPU temperatures dropped full 10*C at load by switching to the Solano from Thermaltake Soprano (which is unbelievable considering people spend $$ to shave 2-5*C on ultra-high end super coolers). My load VCore is 1.0V. How high is yours?

I put the case cover on, and the temps went UP !

Also, do you have adequate air flow in your case (or is it cramped?) Do you have external fan exhaust CPU cooler or does the heat from the CPU get trapped in the case? Sounds like either cables or hard drives in your case prevent good airflow or the case is simply inadequate (for example Antec P182s have horrible air flow compared to say Antec 1200).

When you are running 2 cards in SLI in the same box, it's natural for one card to run much hotter than the other. I remember someone (happy medium?) linked all modern GPU temperatures compared (in CF and SLI too). It showed much higher temps in SLI modes.

 

[Nirreln]

The GF100 is a hot chip and running a high load on that SLI setup is going to create a lot of heat, no other way around it.

 

[Grooveriding]

Do you have them right beside one another, or with a space between them, space meaning a space the size of one of the cards.

With my 480s side by side, the top card would hit almost 100C. The 470s and 480s are terrible directly next to each other in multi-gpu on air cooling.

So I'm guessing they are right next to one another ?

 

[tweakboy]

70's and 80's are ok. But not 95c cuz once it reaches 100c , Go fry a egg on it, put foil and put egg on foil watch it bake giving you a create yellow and white pour some salt and eat it.

No but really ,, 95c is probably because the other card and this card is just too much heat going on. Imagine eliminating one card,,, ull should go past 85c Since your SLI then that two hot products side by side. Room ambient temp should always be 74F no higher or lower.. If your room is hot since its summer then thats the reason for high temps..your side case is open but if your room is 78 or 80F Then your gonna have to use some kind of AC for your room, for hot summer nights LOL gg and gb

Well, whether it's too hot or not has been debated since the card's release. A lot of people think that it is. nVidia seems to say it's ok. What else can they say, really? It's not unusual.

Yep, the mid-90s are within spec according to NVIDIA. However you had better get a lifetime warranty to cover your butt just in case.

As others have said, case, card proximity, fan speed, and load are all factors.

I'm having very good results using a HAF-X, lots of air moving across my 480s:

Spacing is a factor too, I have to run them in top two slots. Case helps a lot though.

Regarding load and fan, here's Metro 2033 with fans on auto hitting about 75%:

Heaven benchmark (more demanding/load = higher auto fan speed):

Heaven with 70% fixed fans, big temp jump:

Load is your biggest factor. As you can see from my Heaven temps, fan speed is a big factor. You could increase fan speed further, or try moving more air across the cards.

Again, it has been mentioned many times before that almost Fermi reviews mostly use automatic fan profiles. NV intentionally created a conservative fan profile which means that a lot of cards will not scale fast enough to appropriate fan speed at load. This is why you are seeing 92-95*C temperatures for GTX470/480 series. For example, my eVGA GTX470 will never exceed 55 percent fan speed at load in games and then my temperatures rise to 93*C!!!

In reality, in a well ventilated case, a GTX470/480 will run about 10-15*C cooler compared to the temperatures posted by almost every review website (of course 5850/5870 are far superior for temps this gen ). I can tell you that my GTX470 runs at just 77-78*C at 66 percent fan speed, both cooler and quieter both than my 4890 did.

The problem OP has is that he is running 2 cards in SLI. This means the heat of the 2 cards situated close to one another is exacerbating the problem. The 470 is no hotter than a GTX275/280/285/4890 are if you set a manual fan profile. I can't stress enough the importance of a well ventilated case and having a CPU and PSU fans that exhaust air out of the case.

All in all, I would say that the heatsinks on 470/480 are just poor quality given the heat load.

 

[OILFIELDTRASH]

Mine runs low 90's under severe loads. I have the stock fan profile. Just gonna run it as is. Nvidia says it's okay and evga is backing it up with a lifetime warranty. I have an awesome case and airflow. Cooler master atcs 840.

 

[Petey!]

Sounds like terrible airflow in your case, especially if removing the side panel creates a big temperature difference. Also if the cards are sandwiched together without at least a space between them, then the top card will always run 5-10 degrees hotter then the bottom card because its sucking warm air in through a tiny gap.

Get a better case, and see if you can put them in more spaced out PCI-E slots. What is your MOBO and Case?

 

[RussianSensation]

Have you tried setting a manual fan profile to say 70 percent fan speed at 80*C or above and see what happens? I have mine set at 32 percent fan speed all the way to 50*C for idle use and then connected that straight line to 70 percent fan speed at 80*C, and to 80 percent fan speed to 90*C (but it never goes this high, just a precaution hehe).

So the fan profile looks like this ___/

You need to reread the OP. He's not running stock fan profiles and he's still running that hot.

I don't think it's poor quality heatsinks. I think it's from dissipating ~300W.
