My 11 year-old computer started dying and I haven’t been impressed with how current case designs deal with air flow from high powered GPUs. The two main problems I see are that:

• Some hot exhaust from the GPU gets recycled back into the GPU
• Some hot exhaust from the GPU gets fed into the CPU

For systems with high power CPUs and GPUs, this would seem to be a problem if you want to keep your fan speeds as low as possible. Given the current fan cooler designs of GPUs, I’ve wondered whether the system might be improved by providing a slit exhaust in the side of the case over the GPU. This would allow a significant fraction of GPU heat to escape from the case without being fed back into the CPU. This would also prevent some of the GPU exhaust from being fed back into the GPU. A potential downside would be that the slit might also allow more fan noise from the GPU to escape.






GPU shortages sabotaged my original plans for an RTX 3080 GPU, and I ended up with an RTX 3060 Ti to go along with my AMD 5950X CPU. I haven’t attempted to cut a port over the GPU since the standard case configuration seems adequate for the moderate power needs of the RTX 3060 Ti. However, I’m still intrigued with the concept of an exhaust slit on the GPU. I’ve seen some clever ideas presented here by others, so I thought that I present this idea in anyone thought it useful.

I can't see your images and I don't know what you mean by ,,slit exhaust". You mean this nowadays oldsql side panel grills for fan?

I personally don't see a problem with GPU noise if you buy just higher tier, oversized models - these are quieter than I would wish for and even then can stay definitely cool like 70C. Just make GPU 40 cm long and absurdly thick and it will nicely and quietly cool God only knows how much power - 3090 Ti shows how size matters (hehe). Other problems are high-end GPU's memory temps (which make fans running faster even when the chip is cool) and how these crazy amounts of heat exhausted from the GPU affect other components (their temps, so noise, but also lifespan).

I can see the images fine in Firefox on my desktop and in Safari on my iphone. I just looked in Chrome and they don't show up. The images are png files. Maybe Chrome doesn't support those. I'll edit the post and replace the images with jpgs. I'm going out of town, so it may be a week.

The "slit" I'm talking about is a hole in the side of the case in the shape of an elongated rectangle over the edge of the graphics card. It's obvious when the images are visible.

No images when viewing in Firefox, Chrome, or Edge.

I'm having a terrible time getting the original post edited. I can reach the edit pane, but the changes aren't being implemented after I press the Submit button. Here are the 4 images that are embedded in the original post.

Now I see what you mean. Thanks for uploading these pictures, because I would be too lazy to log here from other browsers :> Your slit seems to make sense, but the question is why nobody (from manufacturers) have never tried it (no sense to wonder). The problem with GPU's heat is mostly other (upper) components' problem and these are realitively easy to keep cool. Heat goes up, front fans' job pushes it thru back grill, but part of that goes up and cummulates here until back fan exhausts it and increases temperature inside the case. The higher temperature inside the case, the harder for cooling solutions of components to cool. This temperature comes from disproportion between fesh air coming and heat leaving, so the best way to fight it are top exhaust fans. Your slit seems interesting, but it would work only with half heat from one side of GPU and would be also noise-liberator.
