[SOLVED] Need help for GTX 1080 SLI cooling???

[hermtm2]

Hello,

This is my system

• CPU: AMD 3700X
• M/B: ASUS PRIME X570 PRO
• RAM: SAMSUNG DDR4 16GB x 2 (3600 O/C)
• GRAPHIC: GTX 1080 x2 SLI

I just make the 2 GTX 1080s SLI, but there is only 10mm spaces between them.
I have no idea how to cool the 1st. 1080.

The temperature of the 1st card is 83 Celcius (72 for 2nd one) after Time Spy and Fire Strike tests.

Can you guys help me out?

The image is locked or something, so I'm unable to see it, but with the info you have provided...

Are you using a 2-slot bridge? If so, this combined with 2 and 3-fan aftermarket cooler models will always result in the top card overheating. 10mm is simply not enough space for those models.
They need BREATHING ROOM - about 25mm. The solution for this is getting a 3 or 4-slot bridge.
2-slot bridges demand the blower style cards; this is where they excel.

NVIDIA RTX Graphics Card Cooling Issues

With the RTX series of GPUs, NVIDIA has moved to using dual fans as the standard cooling layout on their GeForce and Titan video cards. This is a big change from past generations and has even bigger implications for using NVIDIA graphics cards in multi-GPU workstations. Let's look at what...

Sorry for losing the image.

Since there is no space for graphics on my ASUS X570 pro M/B, the 2-slot bridge is only available.

I plan to make air holes from the side panel which I already replaced from tempered glass to a plastic material(PC). If I modify the panel further, I could put 2 of 120mm fans on the panel.

I am not sure that the 2 fans can blow enough air through the 10 mm space.
Otherwise, I will give the SLI setup.


Thanks,

Ryan.

83C after a benchmark in a confined SLI setup is entirely normal, and acceptable for use.
If you are really concerned, you can go ahead and add in the side panel fans.

The distance between the PCIE x16_1 and x16_2 looks like it needs a 3-slot bridge from the images I looked up, so how are you using a 2-slot? From x16_2 and x16_3?
