What is "shroud" when ppl talk about 80mm + shroud?

[cx32m4]

I cam a cross a post where people talked about 80mm case fan with shroud and socket cooler.
what is shroud? some kind of device that let you attack 80mm case fan to a socket cooler?

is there a picture i could look at?
thanks

 

[Wingznut]

I have one over my cpu.

 

[cx32m4]

Thanks,
is 80mm blowing directly on HS?
or is that just blowing out hot air from HS/F ?
thanks again.

There are simple 60-80MM adapters, which just mount on top the heatsink with 4 screws, then flair out a bit to mount an 80mm fan on it.

That is not a shroud though, that's a 60-80mm adapter


Ah...that's better...my description of a shroud sucked...
See Wingz's picture

Actually my shroud/92mm fan exhausts air. Air comes into the front of the case and exits out the rear. It's an Alpha heatsink/fan, so the cpu fan brings air away from the cpu.

Language......

Winznut's "shroud" is also a short "duct"...both used to guide flow from one specfic component or area to another component or area, for specific reasons such as "get rid of warm air so it doesn't affect cooling of other components"...or "bring cool room air from side of case directly to hs/fan for best cooling of cpu"...(or send warm air to bedroom). Duct is usually longer than shroud.

80mm to 60mm "adapter" is also a "transition piece" when just used to adapt one size component or area on one end to "different size" component or area on other end. Both usually short in length.

But both adapters and transition pieces can also be ducts if one of their functions is also to "guide the flow" from one location to another, and for specific cooling/heating reasons, as above. Then usually "longer".

So clarity should demand that both function and area change, if any, be specified.

Communication is man's biggest problem.;-)

The threads you read about probably referred to the Alpha Pal6035 HSF. The heatsink has a shroud that goes between the fan and the heatsink itself. It sorta channels the airflow upwards. Here's a picture. pal6035

Wingznut PEZ, that's a really tidy case you got there!

 

[Wingznut]

Thanks, man!

Wingnutz,

Sweet looking system. Your cards are set up just like mine (I think): AGP video up top, PCI sound in the middle, Network card on the bottom, each with their own IRQ, no sharing.

Looks like there is a power connector going to the video card. Is that a 3dfx card?

Mark.

 

[Wingznut]

Yeah, it's a V5-5500. I've since replaced that with a Radeon 64DDR. The V5 is destined for PC #2.

 

[cx32m4]

any one have pic of 80mm adaptor?
anyone using 80mm fan on cooler, is it better?
thanks

Wingnutz,

Wow, it is crazy how similar our systems are. Take a look at my system's page. Same processor speed, video cards, amount of memory, size of monitor, size and RPM of hard drive. . .

Twin computers separated at birth.

[Wingznut]

Wow, very nice. Except mine's not as quiet as yours. The two rear fans are much too loud. I'll be getting new, quieter ones next week.

Wingznut PEZ,

You sure are 1
Ugly Dude.:disgust:

 

[Wingznut]

LMAO! I forgot that was there. I tried to convince divinemartyr that the pic was of me. He didn't buy it.

 

[Budman]

hahahahahahaha

 

[CygnusX1]

You can always pull the fan off your Radeon. . . though I'm sure you wouldn't hear the difference over those two front fans. . .

[Wingznut]

Yeah, I can't hear my cpu or videocard fan over the PS and 92mm rear fan. I'll do those two, and go from there.

 

[etech]

Just in case someone want to see some pics and a review of the 80 & 90mm adapters.
