What you describe is negative pressure. For positive pressure, you need to push more air in then you take out.

Positive pressure may reduce dust a bit, as any air gaps will have air going out of the case (pushed out by positive pressure within the case relative to ambient outside) rather than being sucked in... but the vast bulk of dust is still being blown in by fans so it would be far more effective to have intake filters.

With positive pressure you can get deadspots of still air and weird airflow, in my day job where I design room ventilation we aim for slight negative pressure for this reason; we mechnically replace about 80% of the air we extract but the rest is left to natural draught infill to ensure proper air circulation around the space.

Amongst PC builders there is no concensus, some swear by positive pressure (with filters on intake fans) others insist on negative pressure. I'm on the negative pressure side of the fence (no prizes for guessing that correctly)

Ok, yes -- negative pressure is what I designed for.  I guess it's a LITTLE less dusty than if I hadn't bothered, but it's still dusty in there from time to time.

All that I'm trying to say is that we should not go to this extend to adjust and find a solution/fix for a game that has a problem like this while others don't have.

If you set up this sim/game correctly, you do not have to have any of the problems that you mention.

As I see it, there are two approaches you can take (your choice):

1. Run the system cool and give yourself some headroom.  You get this by using reasonable settings in-game, including limiting fps.

2. "You paid for this video card" and you want to run it flat out.  You get this by increasing the settings in-game, and not limit the fps.

The bottom line is that it should be investigated especially when there are so many complaints about it.

This sounds awfully familiar, somehow... 😉

Bert,

 

I hope that you can agree that many people are complaining about overheating situations and PC fans going crazy with this particular product.

It's not my case, you can see from the 2 pictures attached that show my temps. Which are pretty low on both cases. The only difference that is obvious is that one runs GPU hotter +38 C and +22 C on the CPU, quite a significant change.

Anyhow, I agree somehow to point 1 but changing to "reasonable" settings quality of the picture is no near to what was presented initially in the "showcase" before release and to keep on reducing settings just to stay within limits it gets to the point where it will not be close to what we initially witnessed.  Also, I fully agree that limiting the FPS will reduce the stress on the GPU and a few degrees less on the system.

But regarding point 2, increasing the settings and not limiting the FPS it's a perfect recipe for overheating and throttling down the GPU and CPU.

It's really disappointing to see people that refuse to acknowledge that there is a problem and imply that those facts are "theories out of thin air".

I am afraid that this discussion is going nowhere.

Like this?

if you have a 2nd monitor connected you can try to undock a cockpit screen e.g. the garmin by using ALTGr and + symbol to the other monitor. Then for me the the GPU load decreases and temps going down from 75°C to 65°C. I have the 1080Ti and would expect for higher GPU's no visual impact

Best regards

But here's where my build isn't working quite as expected -- I wanted "positive pressure" such that just a little more air was going out, than was coming in.  The idea being that dust is reduced inside the case.  My case insides still get dusty.  Maybe it's not as bad as it would be otherwise, if I hadn't built any positive pressure at all.  And maybe I didn't quite get that right.  Any of you know about positive pressure?

I think the dust argument comes down to what kind of dust filters (if any) your case has and how hard you run your fans.

Two systems as examples:

1. A Corsair case for a system designed for quiet operation that is simply used for browsing and emails that belongs to a relative. I opened the system up after one years use and it looked as clean inside as the day it was assembled. The dust filters were fully clogged though. The system has 1 fan in front and another at the back.

2. My own system in a Phanteks P500A - no dust filter in front, simply a mesh. It was showing noticeable dust inside after only 1 week of use. I use a steep fan curve that favours positive pressure. I don't mind the fan noise too much when the system heats up, I just crank the volume on my surround sound system. The FBW a320's avionic fan noise drown out my case fans in any case. 😆

Actually my 3060TI is running cooler and quieter with SU5.  

Cheers
