EVGA Pascal cards hotspot problem

I see that my thermal pads have now moved to "Awaiting Shipment ".

Wonder if they are being shipped from somewhere in the UK, or coming from Germany?
 
Great news about the shipping, thanks for your efforts Ben :)

I'll be sending mine off I think, mainly because I won't have any system downtime and save any risk by me doing it :D

Well... I've update my primary VBIOS and the new fan curve is still very quiet and not that overly aggressive. So much for some folks thinking that the fans would be spinning at 80% ;)

On my 1070 FTW:
- Now runs passive up to around 50C, rather than the original 60C
- By 60C the fans are spinning at approx 20%
- By 70C the fans are spinning at approx 45%, was 30% originally.

Not sure above this temp, as 70C is the highest that I reached with my quick testing.

Take note that the fans are all but inaudible up to 60%

So looks to me that they have still tried to strike a balance between cooling and noise levels. Appears to me like they've managed it. Certainly doesn't sound like a hoover at gaming levels like some were worried about.

What we now want to see, is someone do some serious testing with some decent thermal test equipment, to see what effect this has on the VRMs.

As to me. I shall go back to my own custom fan curve, as this is set up to suit my case/average ambient air temp/acceptable noise levels. My curve is slightly more aggressive than the new one and maybe overkill, but it suits my personal preference/s and setup :)

PS. Though I shall still fit the "optional" thermal pads when they turn up.

If this is the case on the 1080 FTW, and based upon the test posted previously, this will aid the issue but it still isn't anywhere near enough to be sufficient to keep the temperatures in check with what you would expect of a premium card or against the competition. 45% will still be hopeless for 1080 vrm cooling as the test at 70-75% fan speed shows. I couldn't care less if mine hit 85c and other cards managed 75-80c on the hotspots, but 95c+ is unacceptable. Had I not ran mine from day 1 at 70% for 70c core and used a custom profile, I'd be sending it back.

Did you watch that video? Ignore what the reported temps are, because there is NO temp reporting on the VRM's. Your GPU could be at 30 degrees C, but those VRM could be 110 degrees C..

Yes I did watch the video thank you very much.

All my post was intended to do, was demonstrate what the new fan curve does. I've been reading these damn posts on here and Hexus, EVGA etc. etc. till my eyes bleed. So thanks for your very informative post ;)

Plus a more agressive fan curve will have a certain effect. As the air being blown over the card will be obviously cooler. And there will be less heat bleed across the PCB from the GPU with the lower temp. But as I stated:

I'm NOT trying to say that this is a total solution for this issue. Can't see that any where in any of the "many" posts that I've made on this thread.

Obviously the thermal pad mod is also necessary. Hence why I put the word optional in "quotes". Implying that I think it's anything other than that.

Have a nice day:)

PS. Maybe I should have made my comment clearer. And instead of saying "what effect this has on the VRMs" ... said "what, if any, effect this has on the VRMs"

Another vid showing thermal pad application:

So the top thermal pad covers the chokes and the edges of the vertical heatsink fins touch the pad. As I mentioned before, it seems that the top of this thermal pad is going to get clogged up with dust. The VRMS are under the baseplate, presumably with existing thermal pads making contact between the VRMs and the plate. Does this mod actually cool the VRMs, or just give better results when a heat detector is used to take temperature readings ?

The larger thermal pad that's placed on the reverse of the PCB might help lower VRM temperatures, but the PCB is going to prevent good heat conduction from the VRMs to the thermal pad.

A well designed heatsink would have the VRMs cooled by a plate directly in contact with the heatsink fins.

I seem to remember reading that the amended fan curve will be tailored to the different cards. So the one for the 1080 will probably be more aggressive I would have thought..

But as you say, this isn't really the total solution. As I tried to point out to the chap above, I like many (and I expect your good self) consider the "optional" thermal pads, as anything other than optional.

I think this issue still has a way to run yet.

You make some VERY good points there. As soon as I saw where the top thermal pad was to be added, my first thought as well, was about dust collecting and getting stuck between the fins of the cooler.

Be very interested to see some fully independent tests done on cards with both the "optional" thermal pads fitted and the amended fan curve.

I think this issue is just going to run and run.
 
Just found out about this problem and have asked for the thermal pad kit,.
As I have to replace the thermal paste I would like to put a good one on,any idea what I should get.

Uh oh. Just had my first black screen on my FTW, lasted a good 5 seconds before it came back with a "driver has recovered from an error" etc.

Wonder if the card is about to detonate any time soon.

edit: ok so decide to update the BIOS to the latest. Went to the EVGA site, found the bios revision... check. Check against the s/n on the side of the box (which I still have thank goodness)... check.

Flash the Bios as the instructions say... no errors. Reboot. Oh joy. No fans. Yep they're not spinning at all.

Was the card set to master bios... yes. Did I download update for master bios.. yes, its the only one available for that revision. Its aint working. Check the BIOS revision number in Nvidia CP and GPU Z... yep identifying itself fine. Still not working. Had to switch to slave bios to get the fans spinning again as Afterburner was the only thing stopping my card from frying.

You couldn't make it up. :rolleyes:

Another reply from EVGA:

Hello,

I do apologize for any confusion this matter has caused as I would like to take the time to clear up the any issues you may have about the 1080/1070. First, Our CEO has not come out about anything related to this "issue" and these incidents are isolated to a small amount of customers. Any electronics are going to have a probable rate of failure and this is no different but has been completely blown out of proportion. The EVGA GeForce GTX 1080 and 1070 do in fact have thermal pads as air alone could never cool this area enough to operate properly. The test that was run causing people to be worried was with a benchamark that has been known by Nvidia to damage cards in the past called Furmark and is not even compatible with Nvidia Pascal cards. Due to this the drivers by Nividia actually have it built in so that if your are running this program the card will throttle down. Some people know how to get around this and will run the card in extreme environments.

We are offering extra thermal pads to customers that want to see better temps when pushing the hardware however this is not necessary and is COMPLETELY OPTIONAL These additional thermal pads will be installed between the backplate and the PCB and between the baseplate and the heatsink fins only as these add additional support to the card for extreme use. These cards are within spec and will run under normal circumstances with no issues. We are here to support you and if there is any issues with the product you are still covered under its available warranty.

We have also released a VBIOS update to fix the issue as well along with the Thermal Pads we are offering. You can download it here http://forums.evga.com/EVGA-GeForce-GTX-10801070-PWM-Operating-Temperature-Update-m2573491.aspx . If your card does not have one available yet then it will be available very soon.

If you would like to have the card replaced with a model that has the pads installed we can support you with this request. Please make sure that you are logged into your EVGA account and then go here http://eu.evga.com/support/rma.asp to submit the RMA request.


Please read more about the thermal pads in the link I have provided below. Once again I would like to take the time to apologize for any inconvenience and confusion this matter has caused.

Regards,
EVGA

I'm done with this now.

I'll apply the bios update and suck it up.

EVGA won't be getting any more custom from me.
 
I really like the support and warranty provided by EVGA and how they work on that front and they probably offer the best service in regards to this.

But I do find their build quality to be sub-par in terms of coolers and material compared to that of other brands.

It is an odd place to be as it seems to be of two extremes like you have one CEO going we need to give all our customers all this as it is what is best for them and we will do at a cost that isn't too extreme. Then the other CEO goes, hang on we will only make 'X' profit then and it just isn't enough, lets only use this material and don't worry about those pads, we can see that the card works within spec as long as no one pushes too hard so let's save those pennies there and OK we are good to go.
 
I updated my EVGA GTX 1080 SuperClocked ACX 3.0 SLi setup with the new Vbios yesterday, and with no issues at all.;)

I used to have a custom fan profile with MSI Afterburner, however I now noticed with the new Vbios and using the custom fan profile, that the custom fan profile actually never really worked with the former Vbios !:eek:
I realized this with the new Vbios when the fans suddenly made a wooosh (hoover) sound when hitting the 68~70% fan curve I made when the GPU would hit 70°c, and having GPU-Z logging the rpms I could see the fans hit around 4400RPM. This never happened with the old Vbios where I never heard such a noise when hitting 70°c, and checking the fan speed it would sit around 2400RPM and MSI Afterburner would still report 68% fan speed.
Quite odd indeed :confused:
