Default Vacuum Case Cooling. Ideas?
The title may be misleading. I don't want my case to produce a vacuum such as space.

What about hooking a ShopVac up to your case? Reverse the flow of air, so the hose blows into your case. Then suck the air back up with an outlet hose, put it through the filter and then out again into your case.

Haha, as I type this up, I reveal a flaw in the plan. The hot air just circulates within the closed loop. How about if you were to place the tubes in cold water, or pass them through a fridge or outside in the cold?

Well, this is turning out to be quite an idea, I don't think it has any hope after typing it up. Anyone have any ideas?

Basically.... you want a high-speed fan for you case. Just get a 4000RPM Delta fan.

Haha, I'm not serious about the idea. I'm just wondering what everyone thinks about it. The noise would be ridiculous!

yay u figured it out
hot air recirculation

sticking the tube in cold water won't do anything; what's the flow rate vs cooling time in the tube? even a radiator won't do much

so in the end, it's just like saying blowing cold air from outside into your case, which may cause condensation

Yup, oh wells. I was hoping for something...

The bong cooling is a sweet idea. I thought of using evaporation cooling, but couldn't figure out an apparatus to do it. I'll definitely do some research on bong cooling now.

If you didn't have an "in" hose, and just had the vacuum accelerating the exhaust I think it'd cool pretty well.

it could interrupt any airflow your case has; intake fans in front, going straight to the vacuum hose
i.e. your GPU may never get any air at all, and overheat
that's why the majority of users have more intake than exhaust fans

if you can figure out how much air the vacuum is sucking and put even more air in with a bunch of high speed fans, that may work, but then you'd just go water if you did that

That also crossed my mind [after I realized I would just be circulating hot air]. It would act just like a high powered fan except much louder.

I suppose... lots of turbulence too.

Without air in your case, you will not get any cooling at all.

But you want as much air going through your case as possible to get the heat out.
