Will My Case Airflow Keep Temperatures Low With This Setup
Posted by Coralyvexin@reddit | buildapc | View on Reddit | 15 comments
I am wrapping up my first high end gaming build and I want to make sure my cooling and airflow plan is solid before I order the last fans. The PC will run long 1440p sessions in a room that can get warm.
Parts list so far
CPU AMD Ryzen 7 9800X3D
GPU RTX 5080
Case Lian Li Lancool 216 with mesh front
CPU cooler Noctua NH D15
Fans three 140mm intake front two 140mm exhaust top one 120mm rear
Will this give me good temperatures and quiet operation or do I need to add more fans or switch to an AIO for better results?

I ran two front 140mm intakes and just one rear 120mm exhaust on a similar case with a 13600K and 5070 Ti. Temps were fine - a lot of heat will just get blown out the top mesh anyway.

My 7800x3d was thermal throttling like crazy, idled at 60+, 90 under load. Thought my old AIO had problems/bad contact with CPU. So I switched to Arctic Liquid Freezer III and now it idles at 44 and maxes out at below 80.
But when I was swapping, I unscrewed my AIO fans from the radiator to reuse the extra fan on my rear, and realized between the fan and the rad it was completely covered by dust, no air could get through it. https://imgur.com/a/GtMTi8h
I often clean the mesh parts of the case fans but it never occurred to me to unscrew the AIO fans from the rad to check in between... I guess what I'm trying to say is that as long as you thoroughly clean your components it would definitely be enough.
My setup has less fans than yours if that helps, small case Fractal North

what are you doing with the two 160mm fans the case came with? (the 216 won't fit 3 front 140s)
just use those, the rear exhaust and maybe one top exhaust at the very rear position. If you really wanna go crazy put 2 140s on the bottom.
That's it for an air cooling build.
you won't get any improvement from any of the other top fans

That's plenty of fans and way more of an air cooler than the cpu needs.

Very helpful, thankss

you might have better results (and a cleaner case) by having more intake fans than exhaust. if there is a filter on top, set those fans to intake as well.

Not sure if you looked closely or maybe confirmed elsewhere that 3 140mm fans fit up front. Their site says only 2. I have a similar sized case that I've had for years (Fractal Meshify 2) with 2 140mm front, 140 top and 120 back. I also have a similar cooler (bequiet pro 3 or something) and my cooling is fine.
So I think if you keep the 2 160mm front, and 140mm top and back you will have a nice slight positive case and not worry about 120mm fans.

Man that's more than enough. Ryzen CPUs run pretty cool(even with PBO), the only people who should be using AIOs are Intel overclockers

I would lose the 120mm rear and replace it with the top front-most 140mm fan. When using an air cooler for the cpu, having multiple upper fans can pull/divert the air that should be hitting the cpu fan away from it. If you do want multiple top fans, you can tune them slower but it's easier to just use one top fan or go liquid.

Hint, when you have a 100w component and a 350w component, it's not the 100w component the cooling of which you should be worried about. I'd remove at least one top fan (or turn it upside down to blow air into the cpu heatsink, not rob it) for better pressure balance. And then watch if extra fans are needed to keep 5080 fans quieter.

good temps and quiet operation are kiiind of on opposite ends of the spectrum depending on what you are running/quality of your build.
That being said, you should be cool enough away from danger, room might get a bit stuffy but thats dependent on many things.
SexBobomb@reddit
Well I mean a 140mm fan is both quieter and more effective than a 120mm fan...
SexBobomb@reddit
you're fine - asterisk next to quiet operation as the gpu is probably going to be the loudest component regardless of additional case fan

The 9800x3d will boost to thermal limit by default when you run a stress test no matter what cooler you have and it's OK that it does that. Because of this behavior, in hames that are harder on the CPU, you'll get decently high temps compared to what people are historically used to while gaming. Again, this is perfectly fine and expected. Just make sure results line up with what's expected out of the CPU to rule out the possibility of not mounting the cooler correctly. As for the GPU, make sure you give it some airflow with a front fan moving the air it'll be blowing downward in front of it and it'll be fine. If you only have one front fan, try to put it towards the bottom for this reason. Most temperature issues with GPUs are generally caused by conservative fan curves but good airflow can mitigate a runaway temperature situation which I've had in a case before. Hope everything runs smooth for you!

Should be fine, but we can't predict thermals. You can determine this by building your PC, using your PC, and monitoring temps.
