Definitely going to keep this config and maybe get some better fans for the back so they draw a bit better.



See what you mean about the NVMe drives. They always seem to be blocked by something and the heat sinks they use aren't the greatest. I've thought about installing a floor fan in the case on the right to sit under the gpu. It would push air over the NVMe locations. But so far the temp on those has dropped as well. So maybe I've gotten lucky enough and should just leave it alone. But you've got a good point about rigging something up. Quite often the component designers work within their own designs and focus on that. But sometimes they need to look at the bigger picture. Motherboards are one of those. By the time the GPU, ram, cables, etc. are all installed that little heat sink for the nvme doesn't do much when the airflow to it has been almost blocked.



Anyway, just happy the airflow is much more effective now and it's not something that will sit in the back of my head poking at the engineer in me lol
I'm glad you're happy with it, that's the main thing!

I have always just gone with my gut feeling, decent flow with air/water, clean coolant, good rads and having block orientations correct the performance will still be excellent especially in today's cases built for water cooling like yours!

I made sure to dual loop and put the least load on the rear rad which is the GPU.

I use to run with the rear feeding in and it just didn't sit right with me, that warm air has to go somewhere and the turbulence inside the case made it more noisy....but i didn't have air starvation issues and the temp was negligible.

Oh, here's a good question...I also posted the same one in the cooling section of the forum. But I'd like to hear all of your opinions and why....



For a push/pull rad system, is it better to have it pulling air out of the case, or fresh air into the case? If you are pulling air out, it's helping to draw fresh cooler air in. But you are pulling pre-warmed air through the rad, making it harder to bring temps down in the coolant.



If you pull air from the outside, you are bringing in cooler air across the rad, but pre-heating the air inside the case and need a really good cross system in order to evacuate it so that it doesn't contribute to warming components.



Now as an engineer I've always been of the frame of mind that pulling cool air across the rad is more important (vehicle application). But after watching videos of people testing the airflow in the 011 dynamic box I set it up to pull air from inside the box across the rad. Because they claimed the air flowed better. But I'm thinking that I'm going to reverse the fans to my initial line of though. It's more important for the coolant to avoid as much saturation as possible and pre-warmed air passing through won't help. So what are your thoughts???

ThrashZone Hi,
Well that's thinking outside the box

dwolvin I do like enough color that I can find leaks, but yeah- 90% distilled.

That's exactly why I don't run colored coolant of any form. Last thing i need if there is a leak is stained carpet to top it all off. I stick with distilled for simplicity, cost and cleanup lol
