How to decide on a case for air cooling (warning - pics) - Page 177

Actually I think frozencpu sells shrouds like that. Or you can make your own. If you ever seen one of those small portable A/Cs, it's the exhaust "hose" they used. It's this flexible tube with ridges that make it bendy. Same idea can apply for this. I'm sure you can get these at a home improvement store.

That sheet styrene comes from several manufacturers and in several thicknesses. Model railroaders use it to make buildings.

Are those hard to remodel? Are they plastic?

Hmmm, can you link me to one?

How about the shrouds that go in between the rad and fan, what are those suppose to do?

Styrene is plastic.

 

Fan-to-something shrouds. Those are generally fan bodies. Some are purpose-built fan shrouds. They are used to provide the full width of a fan's output to the next place the air goes. Shrouds in general:

 

 

Quote:

shroud
[shroud]
noun
1.
a cloth or sheet in which a corpse is wrapped for burial.
2.
something that covers or conceals like a garment: a shroud of rain.
3.
Nautical . any of a number of taut ropes or wires converging from both sides on the head of a lower or upper mast of the outer end of a bowsprit to steady it against lateral sway: a part of the standing rigging.
4.
Also called shroud line. Aeronautics . any of a number of suspension cords of a parachute attaching the load to the canopy.
5.
Also called shroud·ing. Machinery .
a.
(on a nonmetallic gear) an extended metal rim enclosing the ends of the teeth on either side.
b.
(on a water wheel) one of two rings of boards or plates enclosing the buckets at their ends.

 

 

In computers, we most often use the word 'shroud' to mean anything that covers a region and keeps the air from mixing with the air outside the shroud. Usually we use shrouds to direct airflow, very much like a duct.

 

Sometimes we use the word 'shroud' to mean a cover to hide something, like 1. or 5.a. above.

I understand. But would fan-to-radiator shrouds produce any better temps?
post #1767 of 2110
Something like this: http://www.frozencpu.com/products/16138/duc-55/Akust_Extendable_Air_Flow_Thermal_Hood_-_70_80_92_120_Fans_-_Black_FG02-0100-AKS.html?tl=g47c121s442

They don't seem very clear on the diameter of the opening. You could always make something like this.

This is how you would set it up:


This setup will definitely get better temps than other ways of mounting the radiator. You won't get hot air mixing with cool air your CPU needs.

Now how effective whatever water cooler you plan on using is a completely different issue. To get the most of whatever rad you're using, you would want a fan attached to the exterior part of the case bottom then have the radiator flushed with the bottom of the case from the inside. Then have another fan on top of the rad for push/pull. I don't think there would be enough room to put these 3 items within the case and the duct.

This is how you would set it up:

Yup, I got the idea. Why do you need the diameter of that hood though? It is compatible with a 120mm fan/rad anyway, right?

It says compatible but you don't want the tube portion to be smaller than 120mm. That would be restricting airflow reducing possible cooling.

Hmmm, ok. How do you do a DIY of this? Not sure if it will be of significant improvement though.
