2080 ti + 1080 ti running hot

[Chrober24]

I have been running a system with a gigabyte 1080ti turbo mostly for 3d modelling and rendering. My primary software is cinema 4d and octane render. I recently decided to buy a gigabyte aorus x 2080ti  to use in addition to the 1080 ti. However, I did not realize that my motherboard did not have much space between the pcie slots and the two cards are almost touching. the issue might be solved if i could put the 2080ti on the bottom, since the 1080ti is a slimmer blower style card. However, there are some necessary connectors on the motherboard getting in the way. 

 

I ran octane bench just to see how bad the heat would be and it was pretty bad. the 2080ti ran about 86c and the 1080ti ran 90c for most of the benchmark. However, my score increased from 313 with just the rtx card to 428 with both. from what I understand about octane bench this is a pretty significant increase and took almost half the time.

 

I am worried though that these temps could severely damage the cards (especially since the 1080ti does not have a backplate) and I am considering using only the rtx card or replacing it with a slimmer blower style rtx card. 

 

Can someone tell me what would be the best option? thanks

Just remove the case side panel?

What case is it?

nzxt h700.

 

I thought about that but I live in los angeles in an apartment with no ac so i have my windows open all the time. can't even keep my desk clean so i don't want all of that getting in my pc.  

 

it's also 34c outside right now and will probably get hotter as the summer goes so those temps would go down a little in a cooler climate

Case is really closed off for airflow, could always get something like an H500 mesh with 2 200mm fans for intake.

 

Should also totally come buy my 1950X system down in san diego for a dedicated rendering workhorse...

take side panel off and put a box fan blowing into the case for added airflow on low. This will solve your temp problems

would love to but I don't have money for more new parts right now. I'm in the middle of my thesis. Also, I do mostly graphics rendering so threadripper would only help a little

To be honest, the temps are fine. I had two GTX 980s running in SLI for over 1 year at 94°C and 98°C under load.

Of course you would want them to be lower for better performance, but if you're fine with the current performance you get, then leave it as it is.

 

Personally I would get a new case with better airflow.

High temps are going to impact the lifespan of the capacitors

True.

I don't think it matters.

2080 ti down clocks at those temps. 

 

My FTW3 Ultra has to stay in the low 70s to get good performance. I average 2040mhz with the defult fan curve and 2100 mhz with a custom cure. I could not do that at 86c.

 

As for it hurting no. Not unless you have messed with the bois. 2080 tis throttle at 84c stock and 88c with the power limit all the way up.

Perhaps it could help to get some more airflow through the case?

Update: I was able to rearrange some cables to get the 2080ti on the bottom allowing for a good bit more space between the cards. Now i'm seeing slightly better temps: 70c on the 2080ti and 83c on the 1080ti. 

 

I did run into an issue where my renderings were crashing with the monitors plugged into the 2080ti (bottom pcie slot). to my knowledge both slots are pcie x 16 so i did not think it would be an issue. seemed quite odd to me. but connecting the monitors to the 1080ti in the top pcie slot solved that issue. 

 

for all the people suggesting to remove the side panel: i did that and did not receive any better temps. The issue with that is that I live in los angeles and do not have air conditioning so the ambient temps are around 30-35c during the day.  I am planning on getting a small desktop ac and point it at the intake for my pc. maybe that will help some.

i live in s fl. so i do have worst temps  in house then you. but that front case is not helping at all.

i've started removing the front panel while rendering to get better airflow. it doesn't have any effect on temps. it runs about 10c cooler in the morning and late at night so the outside temp is definitely a big factor. i think the reason the 1080ti is getting so hot is that its a blower style card so its just sucking hot air from the gap between the cards now. the only thing i can think of now is to have actively cooled air blowing into the case.

What motherboard are you running, also what CPU?

It looks like a "Tomahawk" motherboard...?

The bottom slot could be PCI-E X4 (electrically) instead and coming from the motherboard chipset, again, depends on the motherboard.

That might be the cause / factor of the crashing issue.

 

70*C and 83*C doesn't seem to bad now.

83*C might cause the GPU to fall out of max Boost state, though.

 

How does your case fan / airflow set-up look like?

Have you considered removing the front dust filter to improve airflow?  -- just temporary, to reduce the airflow restriction coming from the front intake fans.

Motherboard is x299 tomahawk ac

I would much rather have the rtx card in the top slot to maximize its performance, but for the reasons listed above, that is not possible. I'm still getting about 1935MHz with stock settings so it seems to be performing okay

cpu is i9 7900x (not the best, but this was my first build and didnt quite know what I was doing yet)

airflow setup: 3x 120mm intake fans on front, 1x 240mm exhaust fan on back, x62 kraken aio on top with fans pulling air out of case

 

I tried removing the filter, the top panel, and the glass for better airflow while rendering. temps did not change. 

I'm pretty happy with the performance now (gpu rendering is about twice as fast). would love to have cooler temps though so I'm not sweating all day while working

Ah okay...the two PCI-E X16 slots are definitely running at X16 / X16, and directly through the CPU's PCI-E data lanes.

Weird you are encountering that issue...

 

Okay if the temperatures don't change, then case airflow is not the problem.

35*C room / ambient along it enough to offset the temperature.

35*C and 48*C delta over ambient is pretty good .... with crappy airflow cases you can be seeing 50*C ~ 60*C+ deltas.

 

Have you also tried setting up a custom fan curve, or a more aggressive fan speed?

THAT said, given that the GTX 1080 Ti is a blower style card, it will inherently run warmer...compared to an open-style cooler, like the RTX 2080 Ti.

I emailed otoy (rendering software company) as well as gigabyte (gpu company) to see if they knew the cause, but i have not heard back

 

both of my cards have curves set to reach max rpms at 50c. this is pretty aggressive and loud, but i don't care much about sound. I expected the 1080ti to run a bit hot because it reached into the low 70s on its own. I imagine the culprit now is just the fact that it is pulling air straight off of the 2080ti backplate so the temps aren't going to change much unless i blow cold air directly on the cards. 

 

I guess i could return my aorus extreme and get the waterforce version haha
