Fan replacement recommendations?

Hello all,

I just finished building my i9-9900k build in the Fractal Design R6 case. I have the H115i liquid cooler that does a good job cooling the CPU mounted to the front of the case with exhaust out the back.Seems right now that I have a bit of a neutral balance of flow at the moment and would like to get more of a positive pressure in the case. I don't really feel that much incoming flow through the rad even when those fans are maxed out at 1000 rpms. I would like to replace those with new fans and was wondering what your recommendations for that would be. Looking over the options on New Egg and there are a lot to pick from and I am not 100% sure what I would be looking at. The Noctua A14s look pretty good. Not sure if just anything that goes up to 2000 rpm would just be a better option or what would be best for that application.

The Noctua A14s and Corsair ML fans are great choices here for noise and static pressure. But truthfully, if you have no thermal issues on the build, just add a fan or 2 on the top of the case blowing down to increase airflow in the case as well as give airflow over the VRMs too.

Yeah, the VRMs seem to stay surprisingly cool. I have the Aorus Master X390 board which has great cooling on them. The only concern I have is my GPU is getting pretty hot. Gets up to 75c under load. Though I don't know if front fans will help a lot in this case. Even with the side panel off, it only dropped by about a degree.

Does opening or removing the front panel help? Are you using the stock case fans?

Ahh. Thank you. I didn't know that. Lurked this forum for a long time but haven't really posted much.

I am using the fans that came with the H115i cooler. The case fan is in the back. Going to try and put one on the bottom but that might not breath well. On the front with the door open doesn't seem to make much of a difference, even if I also remove the filter. Not sure if it matters (don't think so) but I do have the fans configured in a push config rather then pull. There was nothing in the manual for the cooler about which config would be better.

Oops . Needed to tap the quote posts button. I will learn this forum yet >.<

It is almost like I haven't used a forum before.

no worries on that, growing pains. Reading your reply, 75c is perfectly fine for GPU temps under load honestly.

Push is generally better. The case should come with 3 stock case fans. Did you remove the original front fans or are you using them in push / pull with the H115i fans?

What graphics card are you using?

Stronger airflow from the front could help that. I found in my case that if there isn't any horizontal airflow over the graphics card a hot air pocket can form there.
Gpu temp dropped 10C in my inwin 303 after I installed a fan that creates horizontal airflow. The 303 has vertical airflow design, though it doesn't quite work. I had a strong exhaust in the rear (NB eloop), and the card's temp kept rising, while the exhausted air wasn't getting warmer. Creating horizontal airflow was the solution.
Put another fan on the back of the radiator (as pull) so air from it flows over the card. That should boost the air just enough to clear the hot air pocket.

I did remove the stock fans for favor of the h115i fans. There is none in pull, only push. I have room I could add one back as pull but the upper one is blocked due to hard disks.

I have a 2080 in it.

Going to try that tonight as I have the case fan I can use and the space to put it. I'll probably start by just setting it to max on the motherboard. I think the board can also control speed based on pcie 16 temps.

The lower fan in pull is probably more beneficial for the graphics card anyway and adding the stock case fans back would be better than not using them at all. The second case fan can be mounted at the bottom for intake if you don't have cables or drives in the way.

That space is pretty open. I probably could put one there too. Just would need to use some zip ties to hold out the power supply cables.
