EDIT: CoolMaster Aero 7 - right headed thinking?

Just as I press "Post Message" something happens and IE give me "can't find whatever".

Ok, here's the site, you fill in the blanks.
Aero 7

EDIT: See my next post a few down.

Still wondering how the gerbil cage performs

 

[Lars]

How loud is that HSF supposed to be? (Did not see any db ratings on that site)

 

[HiTek21]

i bet its somewhere between 15 - 35dB. wonder how well it performs.

Ok, here goes again.

With regular fans,
1. the greatest velocity of the fan is at the outermost edges, so you can draw a circle, (kinda like the dripline of a tree for you horticulturalists) where the highest velocity and volume of air is deposited on the heatsink surface.
2. an air deadzone or 'shadow' is created in the center of the heatsink where the fan motor resides. These two points lead up to the next statement about heatsinks.

With heatsinks, the heat is deposited to the center of the heatsink (by the core) where it must first migrate outward towards the heatsink edges (thermal kill zone) before it meets the higher velocity air.

The ideal solution would be to not use a heatsink other than the core itself. (Hold on, let me finish.) To think of the core itself as the heatsink and to direct enough 'cool' molecules whether gas or liquid to the core surface to absorb the heat. This is the thinking of water cooling where the highest velocity of incoming water is directed at the center of the block and the return off to the side. Of course, water does not compress so this approach is questionable for water.

I personally just ordered a Thermalright SLK-900U with a 92mm panaflo which now feels stupid to me. Creating a larger heatsink to attach a larger fan while moving the higher velocity air farther from the center of the heatsink is like telling the problem (therms) to go chase the solution.

Conclusion: I think the CoolMaster Aero 7 is a big step in the right (thinking) direction. Now if only I can attach one to my SLK-900.

interesting design! What is the price?

I think this is also one of the reasons the zalman flower cooler works well with the new adjustable bracket, you can adjust the fan so its not directly over the hs. Wasn't this also the idea behind the TSD (?) fans, the ones with the motor on the fan blades?

Some heatsinks take this into consideration with their designs, the AX-7 comes to mind....

 

[Nerdwannabe]

Cage fans also has tons of "torque" (max air pressure). This is especially effective for those tidely spaced fins heatsink. Although cfm is not as good as the axiel fans, I think it should perform above average.

 

[bupkus]

If Axial fans are the most efficient cfm movers, I'm thinking of a case with a big fan on the side panel with a funnel attached directing the air down towards the center of the heatsink. From there the air would be forced sideways to cover the remainder of the hs. Anyone wanna start a company? I'll sell that idea for a CoolMaster Aero 7.

OBTW, the Aero 7 is only 70mm cubed, although the cylinder can be made longer without increasing the height.

I want an Aero 9, 92mm cubed with a room addition for my case.
Again, I crack myself up.

Somehow I think this overheating problem and it's solutions are getting bizarre. Maybe the chips should just run cooler?
Can I get an Amen, brother?
