Hi, with this case I've currently got 4x BeQuiet! Pure Wings 2 (1000rpm) setup like this:

Are those the optimal positions for airflow and low temps? Have seen temps get quite hot recently in past few weeks. Rest of PC is 3770k + hyper 212 and RX 570.

I will be interested in this thread as I am looking at potentially buying this case. The Pure Wings 2 fans are very low speed though so I guess this impacts airflow. The top panel also seems a bit restrictive without the magnetic top panel replacement.

Low airflow indeed. When I put my hand behind fans I can barely feel anything (when front panel is on). In fairness everything is silent when idle/light gaming but after heavy gaming the CPU and GPU fans get loud as I assume the case airflow is too low.

Ok, I have just ordered the case and also 3x extra 140mm fans (same as come with the case so that the soud profile is all equal) so I will have 2 pulling air in, 1 out the back and two out the top.

Have you tried taking off the top panel and using the black filter panel that comes with it instead?

I will be runing a 3700x and a Noctua NH-D15 so hopefully heat will be decently managed with a CPU like that that is efficient. I will be putting a 3080 in there though when they are released, so lets see how it handles that.

Yeah I've experimented with swapping the top panels. Slightly quiter with the dampened one, but hard to tell the temperature difference. I've also taken out the 2nd layer of filters on the front panel, seems to help airflow a little bit. With an NH-D15 it should be really quiet as it's a much better cooler than a hyper 212.

Good way to start might be to read basic guide to how airflow works and how to optimize case airflow in link below:

Link below about how airflow and static pressure specifications relate to real world use might aldso be of helpful:
https://www.overclock.net/forum/22644574-post11.html

Pure Wings 2 120mm fans are really not up to the task of case intake fans. Even at 1500rpm they only make 1.25mm H2O static pressure or 51.4cfm. By comparison, Silent Wing 3 120mm at 1450rpm make 1.79mm H2O static pressure or 50.5cfm airflow. Fan airflow specification is how much air fan can flow at full speed with no resistance .. a fan on a stand with nothng around out. Static pressure is how much pressure fan can push into a sealed container at full speed. Neither of these applications is a way we use our fan.

Static pressure rating is key to fan's ablity to flow a decent amount of air by being able to overcome resistance of things like grills, filters, cables, etc and be able to flow a

High static pressure rating is key to having good case fans. Case intake fans need to have 1.5mm H2O static pressure rating or greater at 1300-1500rpm so they have high enoujgh pressure rating at speeds we normally run our case fans to overcome grill and filter resistance.

3x 120mm high pressure rated intake fans with all openings not covered by fans in fan mounting panel blocked so air can't leak into front of fans and go in circles but must flow on through case and out the back. Remove all PCIe back slot covers to increase rear vent area so more air can flow past GPU and out the back. With this setup of high pressure rated intake fans no exhaust fans are required. End result is a cool and quiet running system.

I would suggest PH-F120MP fan 2-pack for £14.99 so £7.50 a fan, but they are our of stock. :( While their pressure rating is not super high at full speed, they make more pressure between 600-1200rpm than others so move more air through grill and filter applications in speed range we use our fans.

Thanks for the tips there. As I would prefer to not buy extra fans, would you suggest the best thing I can do is remove the PCI covers for GPU and remove 2nd mesh layer on front intake but keep the fans orientated how they are? I think I currently have a slightly negative airflow in case - as the 2 front are more restricted (by mesh) then 2 exhausts which are not mesh covered.

I read it but I'm not sure if the ones I ordered will not aI guess I was just in doubt if the fans were basically going to have no effect.

Anyway, I have been thinking and in the end I think it may be better to order the Be Quiet 500DX with USB-C and mesh front as my room does get very warm in summer. It also comes with 3x fans so I just need to order another two.

The Phanteks P400A / P300A are two other options that perform similarly for temps to the 500DX. The 500DX would be a better option for temps v 500, and in hindsight I would have probably got that if I saw it. Although it does have the same fans the regular 500 has.
But you don't get the sound-dampening with Phanteks, so a trade-off there.

Just found and watched this video and it was very interesting how the different fan configs affected temps with the 500DX/ I just configured mine with the 2x intake and 1x rear exhaust.

Are you going to run yours with or without the removable dust filter at front for better airflow? Seems as the stock fans don't have great static pressure performance they could benefit from it. In my standard 500 it makes a slight difference
 
To anyone who has had a similar issue to me (temps) I've found you can just purchase just the mesh front panel from the 500DX seperately. Costs ~£20 delivered from Germany. I noticed a change from the swap, and can now run all fans at 500rpm for the same temps (inaudible).
