Aluminium case vs. steel - temp. difference?
Does using a alu case REALLY lower overall system temp? The whole thing is supposed to act as a heatsink to lower internal temp to ambient, which makes some sort of sense, but does it work? Any good comparison reviews anywhere?

I don't believe that it does, and if there is any effect, it would be negligeable.
Aluminium is the prime material for air cooling though, but since it's not in direct physical contact with a heat source, all it would do is receive heat from the air in the case, and transmit it to air outside the case. Steel would do that too, but less efficiently. All in all, there are other factors that are far, far more important in keeping the inside of a case cool, like airflow. The hype about Alu cases is blown way out of proportion, In My Opinion... |

And, of course, one of pHaestus' 5 myths about cooling...

Let's say you wanted to fry some eggs. How long would they take to fry if you were holding the pan 2 feet above the stove? That's how effective Al cases are at cooling your system.

I wasn't comparing the two, but you make a good point

ive had two aluminum cases and three steel cases and I haven't really noticed much of a difference in ambient temps as forementioned above; however, I would never go back to steel after having aluminum for the sole reason of weight, which makes a huge difference especially when watercooling (if you plan on moving your case around)

Thanks everybody.
Looks like it'll be steel then! Som |

Thinking about it...
The only cooling advantage might be in the hard drive mounting. If the hard drive rack was of at least somewhat decent thickness, it would help draw & spread out the heat from the hard drives, creating a larger surface area to dissapate their heat. Probably wouldn't help overall temps much, but might help keep the drives just a few degrees cooler. |

What I want to do is see the weight difference...
Thats the only reason why I'd get aluminium...as I've come to find my Antec SX635 is quite heavy...if they make a Aluminum version...which will most likely be Black or Silver...i'd like to get my hands on just the chassis and transfer my beige parts over...

When I went from an Antec 1000 to a Coolermaster ATC-201, my temps dropped... but I couldn't conclude that it was based solely on the material of the case. Structural, there's a big difference between the two.:shrug:

Copper is heavy, harder to work with and easy to warp/distort.
That means a heatsink that can be more expensive and weigh more than half a kilo (this on a fragile cpu). Most people just aren't willing to go this far for cooling. edit: forgot to mention i was talking about copper

Of course u could always do something crazy like this http://www.geocities.jp/numano3/backhe.html of course and hook up your CPU to the case, this would work probably VERY well in a Al Case

Nice link, Quokked. I like the idea of adding a heatsink on the back of the mobo. |

Aluminum: 237 Copper: 401 Silver: 429 Steel: 15.1 higher is better, all measurements in (W/m*K) You can see from this that for heatsinks, silver would be ideal, but for price/performance ratio copper definitely wins. |

Oh right ease of manufacture and all that!, I thought you were gonna give me the "Alu gives up heat better than Cu" speel ...
I dont think putting a HS on the back of the CPU would do alot, but it's something I've been meaning to do to my GPU for an age!, GPU is actualy mounted so there is some conduction, the air under the CPU socket makes it pointless IMO :shrug: ... The NB would benifit too... I thought about putting a small quiet(40mm/50mm) fan under the mobo drawing air under and venting through the mobo mounting panel/tray. do you think it's worth it?, would it cool the PCB/components down worth a damn?... |

HOw about mounting a small fan on the outside case wall just as is done for side blowers on the other side of the case. It would draw in outside cool air, through a small duct to the MB plate, then have a hole cut into the MB plate to let that cool air hit the back of the MB and spread out from there.
I have to think some have done this before, outcome? |

Same difference! ...
I was thinking of doing it mainly because I was getting higher system/mobo temps than I was CPU temps!!!, found out it's cause the thero' is at the usual bottom left of the mobo and I have a SoundBastard 5.1 in the lowest PCI slot. those S(o)B's get very hot!, for what they are anyways ... Sys/mobo temp : 31DegC CPU/Socket temp : 32DegC Ambient/room temp : 22~23DegC |
