RTX 2080ti - High temps :(

[Meln]

Hello all,

 

I need some help with my system since I am getting abnormal temperatures for a watercooled system. The only thing that I've in the loop the is GPU.

 

My card is the Gigabyte AORUS GeForce RTX 2080 Ti Xtreme Waterforce with a custom loop containing the following parts:

 

Radiator: 240 mm radiator Alphacool ST30

Pump: EK-XTOP SPC-60 PWM - Plex

Fans: 2x120 mm Noctua fans

Reservoir: EK-RES X3 150

 

If I do a normal overclock like the air-cooled cards (2050 MHz core clock) I get to 80ºC (176 ºF) with only 45 minutes of full GPU usage.

 

I don’t know where to start to troubleshoot this. I know that it is important to measure the coolant temperature but I don't have the proper probe right know. However, I tried to measure the temps with a simple thermometer and all I know is that the coolant was atleast well above the 43 ºC (109.4 ºF). 

 

Thank you in advance.

80° sounds fine to me

 Yes sir, 80c is good, your griping about nothing lol.

80°C is fine but considering his cooling its rather high. 

 

I get sub 60°C on OCd 1080ti with 120mm AIO so he should at the very least achieve my temperatures. 

[WereCat]

What case do you have and where are your intakes and exhaust fans? 

RPM on the radiator fans?

Hmm, maybe just had a bad experience with that type of setup then, cause mine was fairly similar to OPs

[SpookyCitrus]

Considering it's a 240mm rad and not in push pull, I'd say the temps seem within normal. 100% usage for 45 minutes with a synthetic stress test, that water is going to get quite warm, 80c under that sort of load is perfectly fine. You'll more than likely not get that hot or even really near it when gaming or with non synthetic usage.

Sounds quite hot to me, does squeezing the card around the die improve the temperatures? I suppose since this is a pre-assembled block you don't want to dissassemble it, but this would be the next course of action unfortunately.

My RTX EVGA 2080 ti XC runs in the 80s underload. 

My RTX EVGA 2080 ti FTW3 Ultra runs in the 70s under load.

 

A water cooled 2080 ti should be in the 60s.

 

Also my normal overclock to maintain 2050 mhz is 72c on the 3 fan FTW3 Ultra. I run at 2070 mhz at 74c. It will go to 2100 mhz but the fans are too loud to maintain it.

With my XC (2 fan) card it is possible to maintain 2050 mhz but the fans are so loud that it is only good for benching.

 

I may get a third 2080 ti. A hybrid this time and going by the EVGA forums I should get 64 to 65c under load.

 

At 80c your loop is all show and no go because a 2080 ti downclocks well below that temperature.

Thank you all for the feedback well I see some people claiming that their watercooled 2080ti cards never go above 50 ºC under full load I don't know if they are real or not

The case is the TermalTake View 37. I have 2 intake fans on the front and a exhaust fan on the back of the case.

 

The fans of the radiator are at 1500 rpm I can post some pics of the build.

Yes, It starts at 2050-2070 and then it downclocks at every ~7ºC until it goes down to 1995-2010 Mhz when it reaches the 75+ºC.

They are, most GPUs take extremely well to AIOs or waterblocks due to the plate being right on the die, they don't have an IHS in-between that and the (usually copper) plate like CPUs do. Even my Vega GPUs stay cool, 53C max on the Vega FE I had, around 63C max (93 hotspot) or so on my Radeon VII if I pump in sliiiightly more than max voltage. A 2080 Ti will probably stay at around 55C max, most likely under. 

[WereCat]

@Meln

I looked at that case and it seems to have severely limited air flow.

Your radiator is at the front? 

[Meln]

@WereCat no, its on the left side (attached to this message).

[WereCat]

Nvm, I haven't noticed there is side intake. Airflow should be sufficient then. 

 

IDK what may cause the issue besides checking if the cooler is mounted properly as it may not be making a good contact with the GPU die. 

[Meln]

@WereCat I did some further testing and If I undervolt the card to 900 mV at core clock of 1960 MHz I usually get temperatures that stabilize between 58ºC to 62ºC under almost full load during 1 hour.

 

Maybe the OC that I was using was too high for the 240 mm radiator? Also, It is not possible to see on the pic above but, the flexible tubing that connects the pump to the reservoir is deformed and consequently tighter near the junction point. Because of this, the flow may be lower on the system which results on lower cooling efficiency?

It makes little sense to me to be honest.

I have no experience with a custom loop btw.

 

But my 1080ti is very simmilar to 2080ti in power and heat output and if I can manage sub 60*C on a little 120mm AIO then I see no reason why you should be getting such high tempes with 240mm radiator on a custom loop.

I know my AIO is only contacting GPU and your water block also has to cool the VRM and VRAM so thats an added heat but I dont think it should make that much difference to the GPU temp.

[Skiiwee29]

I know my 2080ti in a full custom loop with CPU and GPU doesnt get above 55c at max load temps so hitting 80c under load with just the GPU sounds more like a mounting problem with the water block than anything. 

[Meln]

@Skiiwee29 Yes, I also have the same suspection and it is still on warranty (4 years), I don't want to open it since I am not experienced enough

Its either that, or not enough water flow. Even though the pump has PWM, it should also have a molex or sata power cable. Try removing the 4 pin PWM header from your motherboard, presuming you have it plugged in, and just run it at 100% and see if you still get the same temps.

Eeeeeh no, that GPU shouldn't be that hot on any reasonable custom loop. They usually stay below that on air AFAIK.

^^^ If your coolant is hot then you're not moving fluid properly, and/or not getting the heat out of the fluid. Sure there's no gunk in the loop and everything is flowing right? 

[Tristerin]

You do loops to avoid those temps when overclocking, as noted by a few of the experienced folks here - the temps are bad.  I agree with the likelihood of the block not properly touching the GPU die.  Also agree that the pump could be operating at a very slow speed - I run all my pumps on max, you should never hear them imho.

I tried to adjust the loop in the lower point near the pump and the OC is stable at 2025 MHz (core) with 0.943 mV. Now I am getting 61 ºC under full load for 45 minutes. Not the best but it looks a bit better.

Those are much better temps indeed. Still a bit high, but only about 6C off the target of 55C max.

Still not great and over temp IMO for a custom loop. Do what I had suggested. Remove the PWM header from your motherboard and just let it run full of the sata/molex power plug. I have a sneaky suspicion that your running at to low of an RPM to effectively move the fluids around. Running it straight on just Molex/Sata power will run it at 100% speed. Then test again.

SPC pump is powered solely by a fan header.
