Airflow improvement help

[mbaron623]

Hi, 

 

So I have a Ryzen 3800X, on a Aorus Pro Wifi x570-I in a Phanteks Evolv shift, cooled by a NZXT Kraken M22, and a GTX 1080.  I have been having issues with thermal throttling on my gtx 1080.  I attribute this to airflow because the Evolv Shift has  basically no airflow.  My solution is to add an additional fan and maybe CNC some front panel cut outs.  When the front panel is off, I get full gpu usage and get up to around 80C.  When it's on, I hit 80C at 65% usage.  My CPU runs pretty hot too either way, but it's ryzen and not nearly as bad as the gpu. 

 

So my issue with adding another fan is that I am out of fan headers on the motherboard.  I already have a splitter on one of the headers.  I'd prefer not to add another where the pump is located.  I'm concerned that it could cause some issues.  I'd also like to switch over to an AIO gpu at some point so I feel like the fan controller would be necessary.  The only issue is that my only usb 2.0 on the motherboard is used by my Kraken M22.  I would really like a software controlled fan controller.  

 

I know phanteks makes a few and I saw one from corsair as well. I know they all require usb 2.0.  Any help would be welcomed

Shift has shitty thermals to start with.

Why not just get a fan splitter?

I already use a fan splitter.  Only other header on the Aorus x570-I is the CPU fan/pump header that I'm using for my Kraken M22.  Concerned it would cause issues with the pump.  Also have plans of changing my gpu with a gpu with aio, so I'll need the more fan headers.

What issues are you afraid of? Most headers can handle 1A. So 5 fans should offer no problems unless you use some server grade blowers.

The pump will be okay on a splitter?

Use the other one if you are afraid?

The other one already has a splitter.  I was hoping to remove splitters from the equation, but if it won't cause any issues or put too much stress on anything I'm not concerned

It's also a kraken m22.  The pump runs at the full 3000rpm all the time.  If I split it with a fan, won't the fan run at full all the time as well

Hello,

    I am new here and have actually just built something similar. All over the web there are ideas about the original shift case as far as air flow. I am in no way an expert.

 

I have been tweeking mine for the last month and have finally come up with what I think is a decent fan solution. I am not saying this will work for you but it seems to be working for me. I have the same MB with a Ryzen 5600x with the Corsair H60 cooler and and 1080ti turbo.

 

I use this setup for mainly SteamVR and OculusVR games. I originally just went with what Phantex suggested which was based on the idea of taking the complete water cooling  path. I added a bottom front intake fan and the rad(CPU) as intake at the bottom. The CPU averaged at 39C with GPU at 81C after playing forty-five minutes of each of the following: Phantom Covert Ops, Pavlov and Robo Recall all on ultra or high settings. So the CPU of course was fine and the GPU was a bit higher than I liked.

 

After messing around with the fans I have arrived at this:  Top front and bottom -140mm intake daisy chained to the case fan header. The rad  is now  setup in a  push pull config with two 120 mm fans daisy chained and ran to the CPU fan header. Of course I was unsure about this as heat of course rises but this has actually yield good results. With the un-modded front cover on after the same gameplay/settings listed above, I am getting 34C on the CPU and 76C on the GPU. So these are pretty good from what I can tell from literature online and the kicker is when I take the front cover off, I am getting 28C on the CPU and 62C on the GPU.

 

So once I do get the front of the case modded overall temps will get even better.  

 

Fans used are Stella HP ARGB 120 PWM and 140mm variants. After doing the math the headers can handle them no problem. 

 

I hope this gives you ideas and perhaps helps with your cooling.
