First timer needing some pointers. Have a couple questions for 2080ti and i9 setup

Build Help

Ok here is some background:

Case: NZXT h700i
I have a i9 9900k overclocked to 5.1ghz @1.295 cooled with a x72 kraken with 6 fans in push pull configuration.
Temperatures are great. It never get past 50c while gaming. My 2080ti on the other hand needs to be tamed.

​

My 2080ti EVGA Black edition (reference pcb) cooled with EVGA hybrid kit (thin 120mm radiator with AIO) is averaging 65-66c while gaming. Fans also in push pull configuration with an aggressive fan curve. 80%. The pump is fairly quiet the fans are just annoying me but I have to keep it high . If i lower the fans temps get closer to 69-70c. I do have an overclock on it +100 on the core clock. After about a week with messing with settings and various fan configurations, I have had it and I want to go custom loop on the gpu at the least. I know the temps are acceptable but I want better performance and less noise :)

So my questions are:

Will I be able to get my GPU temperatures under 60c on load and What radiator setup will possibly help me achieve that? ( I was thinking a thick 240m just for the GPU)

​

I will most likely set up my custom loop (Soft tubing) on the GPU first and add the CPU into the loop down the road unless you guys suggest otherwise. Thanks in advance!

I did some tests a little while back and i have basically the same config you do, even with the case : https://i.imgur.com/Z6fSB4t.png

This will give you a good idea on the setup needed and temps at different RPM ranges.

Wow this is great info. Thank you so much for this. I am excited !

I have a 2080 Ti FTW3 ultra that came to me as a three fan. I purchased the Hybrid kit and was able to run the card with it at the same noise levels required to achieve mid 60ies on air down to about 55°C. The memory temps dropped from always clipping 90°C to about 65°C on the hottest reading bank. This was done with a Noctua NF-A12x25 fan fitted to the radiator in place of the stock EVGA fan. Up until about 1,700 rpm, the Noctua did acheived the same thermals for half the noise to my ear. At 1,750rpm to 2k, the EVGA fan became progressively and significantly noisier while being able to drop the GPU temp 3° lower vs the Noctua. My card in this situation with a +80 GPU core offset would typically hold 2,070-2,085 core clock indefinitely while fully loaded up. I liked to run the hybrid fan (using the noctua) at 1,400rpm.

Minus what you've said about the CPU temp, I would guess you have an airflow problem. Given you have a much hotter running chip than I do I am not sure what to make of your numbers with that factored in. Assuming your paste job on the GPU die is good, that is... once assembled, it wasn't too much of a pain to remove the AIO pump/block on the FTW3 and I am guessing it is the same for yours. If your GPU temp doesn't instantly drop 8-10° when unloaded, I would say this would be a good thing to investigate. What method of paste spreading did you use or did you use the preapplied on the pump block?

Yup my airflow was definitely messed up. I addressed the issues and now my hybrid temps are matching yours at about 55-57c

Right on, man. What did improving the flow entail?

Well, I had change my top fans to all exhaust and I changed my front to all ML120 fans and it dropped my temps about 6c all around the board. Idle temp is now 31c.

Overall pretty happy. I think going custom loop will get me into the 50s maybe lower? And less fan noise which would be amazing

Depends on your rads. With (2) 480mm rads and a 2700x I hold 2100-2115 GPU core, and +1200 memory with the GPU temp peaking at 42c in Xcom 2 or DX:MD... the two games i am playing atm that stress the card the most, by far.

I applied artic Mx-4 and cleaned off the original paste of course. Temps were great before but I am not sure why they are spiking.

The temps do drop when unloaded. It idles at 40c if I am not mistaken . I covered the gpu die completely. Hmmm I may take it apart again and see what I can do.
