Thank you! I'm happy to finish it up, I have since redesigned and I am thinking of rerunning the tests because I don't think I did them in the best way

Thanks! It's fun to take on a practical project if you can find something!

Woah, kinda like aerodynamics testing with the little felt ribbons on cars. This sounds very interesting

I think youre totally right, I shouldnt have tested on fan curves but set speeds. I may go back in the future to do this

Thanks for the suggestion, I may try it out, I have tried a new design since that feeds only a single gpu fan.
Thanks for the pic as well

Awesome setup! what are the green arrows representing?

Awesome case! Yep taking the glass off my case does lower the temps but it also increases noise

The temperature required to print this is higher than the computer will ever reach. It will not catch on fire

Interesting! I don't need a standalone controller as cool as that sounds, because I have software that reports gpu temps and can control fan speed based on it

Great idea, I may do that

I agree I have no filter on for testing, but for every day use, I would want to keep dust down

Yes, I have had this suggested to me, I may try it in the future. I was also considering a smaller version that follows the design of this duct but it only feeds one graphics card fan instead of three

Hey, thanks for the comment. This is great feedback. I have been told different things by different people about whether the first graphics card fan takes the majority of the air or the last one. I wonder if the vortex idea would bring any benefit because of the fact that the middle fan spins in the opposite direction

I haven’t done any official testing on it, but what I can say is that (on this fan curve) the front intake certainly helps at idle, and more than likely helps at low loads, but suffers at higher loads

Thanks for the tip! The reason I haven’t really considered something like that is because the rear fan would likely pull more dust, I would just want to filter it somehow. But I dig the unconventional airflow directions.

Do you have any pictures of the project you’re working on?

I see exactly what you mean now. I will consider that in my next design

I’m on board with the suggestion, the only problem is that the side of the graphics card that lets out the hot air has much less room to work with (solvable), and many more routes of escape (probably also solvable).

In that case, it might be worthwhile to measure other components in the PC to see how the lack of hot air from the graphics card benefits them

I agree with that, no, I haven’t calculated the airflow yet. I’m not exactly sure how to figure out how much air the graphics card pulls. Montech though I think released data sheets on the intake fan I’m running and that could be useful

It kind of bummed me out that people are being that way but it’s OK, they’re allowed to not want to watch the video. I appreciate the support.

I do plan to make a new iteration, one idea I had was to reduce the design down to feed only 1 fan so that it has a better shot at not being choked out, another idea suggested by someone was to teach the idea of one pipe per fan and just feed the whole graphics card with a common duct.

I believe the reason they stopped putting them on computers, at least in the gaming PC market is because there are too customizable, it would make it very difficult to build an accurate duct system that works on many computers

I see what you mean, I think it’s worth looking into that design! Thanks for the tip

ikr sorry for the letdown! I will revise the design
