GPU Temps

[DaxInside]

Hi guys

Below is my new rig which I received on Saturday. Im happy to say its well put together and running smoothly.

Im hoping someone can advise me on acceptable GPU temps. One of my cards runs 10 degrees hotter than the other, which is to be expected as it has a sound card next to it. The hotter card reaches 90 degrees which sounds a little hot to me. The PC makes a lot of noise at this temp and takes quite a long time to quiet down after quitting games. Its been a hot weekend so that can't be helping.

At the moment the only exit vents are the CPU cooler fan and the GPU vents. The only inlet for air is the 1 case fan on the front.

Can you take a picture of your PC? Are you increasing the fan speed? is 90'C under load?

Well the maximum safe temperature for your card is 95 degrees although I am not sure what the average temperature should be but I know it is bloody hot at the moment so I would expect it to run a little hotter, 90 is at the high end of the temp scale but I would not say its really worrying.

90'C is very hot, even on this weather at full load I don't reach those temps. I suspect that the gpu fans at not at full speed and the quiet case is likely to influence the temps slightly.

which is to be expected as it has a sound card next to it

Is the soundcard on the PCI-E slot? on top of the first GPU? if that is the case that shouldn't influence the temperature of your gpu.

It was the increased noise from the PC that alerted me to the hot temps. It reaches 90 degrees after about 10-15 minutes of play BF3 at max settings. It runs the game very well indeed!

I can take a picture of the PC when I get home at the weekend. I think im going to add an extra inlet fan on the front as there is space for it. Also one at the top as a 2nd vent to allow some of that heat out. The air blowing from the CPU fan is really hot but I guess thats the air from inside the case being vented and not heat directly off the CPU.

Do the Corsair watercooled CPU fans vent case heat as well as CPU heat? Its hard to tell as the fan is a solid unit.

 

[DaxInside]

I think the sound card is at top, above the first GPU.

Ive not touched any fan controls but by the sounds of it they speed up well enough on their own.

 

[tom_gr7]

like keynes says post up a few pictures of inside the rig, and we can give you some pointers to help with cooling.

90c in my opinion is a bit toasty, but im sure we can help you out.

I'd suggest using msi afterburner to control the gpu fans, set up a custom fan curve so the fans kick in earlier than normal.

It's probably worth looking at your case airflow, you have a very high end rig inside a "quiet mid tower case", so things are going to get a bit toasty. The twp gpu's are going to give of alot of heat, so its important to ensure that said heat is exhausted swiftly. I'd suggest adding some more intake and exhaust fans to the system.

 

[tom_gr7]

oh, it would be worth turning on nvidias adaptive vysnc - you can read about it here - http://www.hardocp.com/article/2012/04/16/nvidia_adaptive_vsync_technology_review/

in short, it will limit your cards to the refresh rate of your monitors eg 60fps. So the cards aint working at 100%. which is probably not enabled at the moment.

nvidia control panel, manage 3d settings, global settings, scroll down and to vertical sync and set it to adaptive. This will massively help with the temps.

 

[DaxInside]

Thats an interesting read and definitely worth trying out. Thanks.

Ill see if I can get my fiance to take a photo of the pc for me.

I do agree, even with my 690 I would barely reach 85 degrees on the gpu and that's after hours and hours of gaming

 

[Boozad]

My 780 hits about 80°C in demanding games on ultra settings so 90°C does sound quite hot. I'm sure this lot will help you get things running cooler.

Another reason of concern, which I mentioned in another thread, is that my build was ready for dispatch after 2 days from order. I don't believe it went through 24 hours of testing followed by 24-48 hours in a hot room. And if it did then at what temperatures would PCS say its too hot and recommend a fan or 2 be added?

As I mentioned in your other thread it might be the case that there was a delay updating the build process, for peace of mind you could contact PCS to clarify the situation but I am pretty sure they have done any adequate testing since it is not in their interest to get the system back for repairs.
You need to provide more information regarding your set up (cables or other parts obstructing the gpu fan) and whether or not you are increasing the fan speed of the gpu at full load. Quiet cases also compromise in cooling but I am not sure how significant that will be in your case, for a SLI set up a quiet case is not really ideal if you are concerned with cooling/airflow.

 

[DaxInside]

I posted that I have not altered the default fan settings for the GPUs or any fans in the case.

There couldn't have been a delay in updating the build progress as the order was placed on Sunday so couldn't have started until Monday morning. It was ready to ship on Wednesday morning at 8am.

Im trying not to jump to conclusions but you should also try to be objective rather than automatically defending PCS. I appreciate your help and your passion in PCS so don't take this the wrong way.

Ill contact PCS later today.

Sorry didn't mean that. Just talking from experience. Didn't notice the fan speed post so maybe that could help, I use MSI afterburner and it pushes my gpu fans to 80% at full load helping a lot the temps. I also notice that you could add 3 additional fans in your case, that could probably help.

 

[DaxInside]

Ive ordered a couple of fans for the case which is going to help. It won't be quite so quiet in general use but I don't mind that. It may actually be quieter during gaming with more fans.

Ill engage the vsync option in the Nvidia control panel too. Plus ill have a play with the fan settings.

It should be much cooler after all that so thank you for the advice.

Ive contacted PCS to ask what temps were measured during testing and at what temps they consider needing attention. Ill post back when I have an update. My fiance didn't fancy taking the side of the PC off so photos will have to wait.

 

[JakAttack]

Sorry to hear you're having trouble Dax.

It has been extremely humid over the last couple of days so you might want to make sure that this isn't causing the issue, after all, we'll be back in our jumpers for the other 350 days of the year I say this as mine personally has been a bit of a bugger recently, and I've even had to rewire it to allow more air!

When we dispatch a system they don't get a 24 hour test, it is usually about 4-8, but does spend about 24 hours being checked over in other bits, you've also got to remember we update them manually, sometimes they can be updated a bit later on, if our QC software detects anything awry, be it incorrect/missing components, faults or high temperatures the system kicks up a warning and will not allow us to dispatch it before sending.

Sadly though, we do not keep records of temperatures before we send them we just make sure they are safe.

For 2 x GTX 770's however, I would expect 30-55 on idle, and 60-80 on peak load, one of the cards will have a higher temperature, as either the fan will be partially blocked by the other card, or it may be pushed at the bottom of the case, which is normally the case for SLI and why we require people to choose a different case on occasion.

If it is running hotter than this, the extra fans can always help, a bit of airflow never hurt anybody, but if it keeps running hot even after this current procedure we may need to take a look.

I also notice you mention that your fiancé has not taken the case side off yet, can you do this? As there may be some blue foam used for protection inside the Pc pushing up against the cards, which will not help temperatures, this will need to be removed if it hasn't been.

 

[DaxInside]

Thanks for the reply.

The blue plastic was removed It would probably blow up if I didn't.

I just got a reply to my email from PCS but the techie read my email wrong and asked me to check the pipes in my CPU cooler to check if its causing my CPU to overheat. Doh! I checked and made sure my original email said GPU, which it did, several times.

Anyway. Ill have more of a play with it at the weekend and ill post a picture up too.

Its a shame you don't keep a record of the max temps reached during testing, it would only take a second for each system and give you a guide to which temp levels cause customers to return their PCs. How hot is the hot room? Surely as warm as a hot summers day in the UK? If not then whats the point? I did ask about the QC in my email but all questions were ignored or answered regarding to my CPU not my GPU.

 

[DaxInside]

Ive not heard from PCS since Tuesday. As I mentioned they replied regarding my CPU rather than my GPU and ignored my questions about QC. I replied asking them to re read my email and pointed out it was my GPU that was over heating.

Not great service although I know I can phone up today before 1pm.

I added 3 new fans to my case and this brought the temp down to 87 degrees according to GPUz. Not much of a difference. Ive also added adaptive vsync on but again that only brought the temp down by a couple of degrees.

Im wondering if the temp sensing in GPUz isn't that great, any suggestions on other programs to try?

Ive added 2 pics as requested. Any thoughts then please let me know.

Kind regards

The fans are the fractal R2 silent series. I added one on the front making 2 fans facing inwards. Then outlet fans on the top and side of the PC.

Im thinking of adding some better fans as I guess these are designed to my quiet rather than effective. Obviously id like to have a mix of both.

I downloaded MSI Afterburner but im not sure what im doing with it. I don't want to overclock, just make the fans go a little faster when they heat up.

I dragged the fan speed bar to 100% and wow, it sounded like it was going to take off! lol.
