Is this GTX 590 defect? - Loss of frame rate.

[paul3000]

Hi all,
I have a problem with my GTX 590 (Point Of View), which seems to be independent from the driver or the game.
Basically it's a loss of frame rate, happening after some time I start a game.

I have made some graph with Afterburner and you can take a look at them below. I started recording just before starting a game.

gpu Temperature and Usage:
https://docs.google.com/open?id=0B5Y-26dYjamXbUNGNE84OGZjcm8

As you see, gpu1 reaches 100 degrees.. that sounds not good to me..

Fanspeed and coreclock:
https://docs.google.com/open?id=0B5Y-26dYjamXeDVoLTFhTnBMVWs

Here I see gpu1-Fanspeed to be 0 the whole time which of course would be bad, but it is also true that I can see only 1 fan on the card and gpu2-Fanspeed seems to be ok. So I'm not sure if I actually should see values above 0 for both graphs here.


Memory and shaderclock:

I don't see anything wrong with them.

What do you think?
BTW, the frame-loss seems to begin more or less when the gpu1 temperature reaches the 100 degrees.. That makes sense.. As far as I know there is some kind of mechanism to protect the gpu.
Also, I very suspect that the gpu reaching such temperature is a sign of a defect.
In any case, as I'm pretty newbie, I wanted to hear the opinion of you experts out there

Thanks for any advice and greetings.

Was wrong about the gpu1 fan

It seems your gpu1 fan is not running at all and hence the high temperature.It may also happen if heavy amount of dust settled in, use a blower to cleanse your card.If everything fails rma it.

The 590 only has one fan, which is mapped to fan 2. Fan 1 will always read 0.

Thanks Virge was not aware of that.

 

[paul3000]

Ok, thanks.
Then I still don't understand why gpu1 reaches such high temperatures in comparison to gpu2. As said, this seems to be the trigger for the frame-rate "stuttering".

The second part of Jaydip's advice was still sound: you need to look into dust and other problems that would be impacting your cooling.

Definitely too hot. The card has got to be throttling. Could be packed with dust. Could be poorly seated cooler that is only now manifesting itself due to dust buildup.
Way too hot though.

Yes any one of these things. Maybe point a fan towards the cards.

Thank you everybody.
I have found the actual root problem: too much dust on my brain circuits.
This has caused a malfunctioning of my brain elementary deduction logic area, which, in turn, caused me not being able to see a connection between the very hot gpu and the dust layer gently overlying the front of one gpu shaft.

Solution: after vacuum cleaning the above said brain circuitry (going through the nose... a painful but cathartic experience), I almost suddenly reached a higher level of understanding and enlightenment: I could finally *see* again, and the problem was now clear like my nasal conducts.
I vacuum cleaned the dust on the graphic card and now the gpu seems to be quite cooler as before.

Just a final warning: there is still the (not very remote) possibility that the vaccum cleaning action could have unfortunately removed some cerebral matter, along with the dust. In this case, please just be patient if one day I will post another question like this
