Palit GTX 970 JetStream - fans issues - Page 2

post #11 of 19
It might be a fan hardware error / problem as Palit says. If that is the case, then can you live with it? If not, then I would return it.
Makes me happy!

Just tried it with fixed fan speed at 55%, as soon as it reached 78 degrees in furmark, the fans spiked to 2300 rpm (100%).
It surely has something to do with the thermal trottle those cards have, set at 80C in bios, when the boost turns of and it starts downclocking.
The reviewers never mentioned this because they had older drivers, or different bios, who knows.

If it bothers you then return the card after the holidays, this doesn't annoy me, I have a bit of coil noise, that's what bothers me.

I would like to return this card, but I had 10 days to do it... I think now is too late, I bought it about 2 months ago :/

Have you tried flashing your BIOS?

That's what I posted yesterday, but then edited the reply, there is a new bios released by palit, unfortunately it doesn't fix the problem.
I've emailed them too, they said it's a fan hardware problem, send the card to warranty and get it replaced, this can't be fioxed by software frown.gif

Hi guys, I have the same issue, however with 980. I have these random spikes as well (see screenshots) and if I set constant fan RPM, the fan speed fluctuate +/- 200 RPM like crazy and you can hear it, pretty annoying. Can anyone of you try to set duty cycle at 100% an monitor fan RMP in afterburner and check if your fan speed fluctuate? According Palit it is normal, but I don't know. In my previos card when I set a constant fan speed, RMP did not change like this, maybe +/- 10 rpm but definitely not -200....

In any case there is definitely something bad with fans voltage control. I've asked Palit and they've said it is abnormal and I should claim a warranty. So I'm going to replace the card, just a bad luck I would say...

Here's answer from palit about fan start/stop cycle and spikes:


When the fan duty is low the fan might repeat start-and-stop action.
It’s a normal status.

About the short spikes of high fan rpm it’s an abnormal status.
Please kindly contact the store where you bought the graphic card to claim warranty.
Sorry for all the inconvenience this may have caused.


And this they've told me about RPM speed fluctuation:

Yes, it’s a normal status.
The fan can’t fix at specific RPM it will spin around a range near the specific RPM.
The minimum RPM of the fan is about 500, but it has some tolerance (maximum +/- 300RPM).


Also it is not mentioned in all those reviews but Palit has one not very nice feature. They have zero fan mode, that is what we know and it's nice but also a minimum duty cycle when fans are on are about 23% which is around 500RPM. And then they have one ugly feature - instead they will switch off the fans completely below this threshold, they constantly make start/stop cycles for maybe 30 second. I'm asking why ? In my opinion if temp is below 67, they should keep fans running for some time to let the card cool down a bit and then switch them off immediately and not doing start/stop cycles because it is very annoying.



Also this is interesting, look at this graph - you can see the fan start/stop cycle until the card reach 25% duty at about 69C. So from 63C to 69C the card run in start/stop mode which is preeeeety annoying. Imagine that you have an application with low GPU load where the temp vary from 63C - 69C - then you have those start/sop all the time. They should definitely alter a bios so the fan kicks in at 63C right on the 25% duty cycle.... Do you also have such start/stop cycles on your card ?



This is cooling down graph, also at the end start/stop cycles.

Hi, this is purely issue with PALIT cards. I had ASUS STRIX and it worked like a charm. But once I've switched to POLIT I'm annoyed with fans noise during this warm state, when fans go ON and OFF. I've never seen this issue on other brands. and this is not normal for sure.

Yes, I had the same issue. Got rid of a card and problem solved. Never ever want to see Pal(sh)it again...

But I will give you one advice. Modify the bios and set your fans to minimum RPMs they can handle when idle. The fans are inaudible and you will get rid of those start/stop cycles wink.gif
