Got the system 3 days ago.

First impressions; with 1 case fan, 2 case fans if you want to call the top radiator fan on liquid cooling for the CPU a case fan is purely a joke.  

Next up, the ventilation for the RTX for the air to be pushed out of the card, though a metal mesh, then through plastic cut out slats, that doesn't even allow for airflow of the entire length of the video card is a joke. 

Putting two fans on this 10.5" card is joke. I don't know what Dell was thinking (its obviously they weren't). These cards require minimum 3 fans.  

If all you want to do with your Dell is do some lite gaming, buy it, as for some reason, the card manages to run cool enough not to trigger 100% GPU fan. I've only tried a few games on this, like Far Cry new dawn and they seem to run fine without affecting the 100% death fan effect.  

My problem comes in, that if I want to do anything more with my computer like say, some distributed computing, like and anything else, than the fans instantly rev to 100%. The noise is unbearable, unless you have the box in another room.  Even with the side cover off, for much better air distribution, and the GPU temps in the low 60's, the fans never ramp down, it's 30% to 100%. That's the options you have.

I tried to install a bunch of fan controllers, and the only one that worked was MSI afterburner, but, even then when setting the fan curve to come on to start ramping up at 55C, I notice it thermal throttling, for some reason even when at 58C. I've come to the conclusion, that this really short card with only 2 fans installed is factory set to ramp up fans when it's being loaded up to 100%. It can only handle so much heat since with no large backplate to soak up and dissipate the heat, the only option is to run the fans at max speed or slow itself down by thermal throttling to not fry itself. Such a nightmare. If you are thinking of using your card for research or playing future games that will load up a 3080 in the future, running the GPU at 100% isn't working out for me.  

So just keep this machine for lite gaming or return it? I bought this for one reason only, for the RTX 3080. I really didn't know it was going to be a custom Dell OEM card that will probably die an early death because it was never designed to be put in such a compact case. It was also not designed for a 2 fan setup. Bad move. In my opinion, I can not recommend this combination to anyone. Unless you need a really small footprint, and aren't going to push your computer to the max.
