If you don't mind a little bigger, I've build 2 computers for my twins using NR200P. Fits very well on their desktop. You can add some extras with money saved and there is a huge community on Reddit for help or whatever. At first I wanted to get them a M1 each but shipping was done separatly so...
Interesting, do you have a picture how you made it? I wanted to do the same initially when I was planning my build but in the end I only ducted the exit of U9S to outside of case. I wasn't sure how to properly fit/attach a duct on blower hole and on bottom of case.
Depends of configuration, the blower push air in a closed space with heatsink in it way, no escape. While 2 fans blows air on a large surface but I know what you mean.
One possibility is that when blower revs fast, it's like a vaccum, sucking surrounding air and can interefere with case air...
I have a 660 Ti blower in one PC and a 1080 Ti blower in the other one. I don't hear any as I control the fans speed with a curve, it's a must or you'll end up with noise. I guess the same need to be done with dual/triple fans cards to better manage noise but like everyone know, at least with...
Dunno if you can try my setup? I'm curious. My main idea was to exhaust 100% air from the CPU heatsink with a duct which I did using tunnel tape but maybe you don't have something to replicate the duct.
I would keep it like this, rear on the case and duct the rear to the heatskink... That's what I did so I'm sure that all hot air is going outside with no weird recirculation.
Tis is a 3D picture, if you can manage to cross your eyes until the 2 dots on the top overlap perfectly you'll see the...
It works for me... MSI 1080 Ti AERO. I use a fan curve to keep it pretty quiet, I have it set at 52% if 88°C is reached then 100% if 90°C is reached and that never happened or I would have heard it. It sometimes goes in the 80's but again never heard the fan goes 100% so to me it's all good.
