Has anyone out there reviewed this heat sink?(see link) Tested it? I didn't do a very thorough search but I haven't found anything, looks interesting. I'd like to see if this design merits any consideration.

http://www.keypad.com.hk/ok/blackhole1.htm

Information from website:

Features:

* High performance , pure copper material
* Low noise thanks to "flower design" , reducing
noisy air-resistance
* High heat capacity due to thick copper base
* Good mounting clips with equal force
* Provided shim enhanced the overall performance
* low profile design


Product specification:

Net heatsink wt: 385 GM

Total wt with fan: 456 gm

heatsink material: pure copper

net Heatsink dimension: 60 x 60 x 25 mm

From the pictures, I can tell you that it will not be all that and a bag of chips as far as performance goes. The low fin density, and low surface area, will make that heatsink a poor performer.

If you want an all copper sink I recommend www.millennium-thermal.com products.

Hmm, I bet a copper end cap would fit nicely over that . . that'd make for one hell of a behive now wouldn't it . . . .

Wghoever made that had obviously taken a look at Alpha's website. I contacted them a while ago about those style heatsinks, alpha did something i thought very grown up for a company, told me that one of their products suck for what us guys would use it for!

i really would steer clear of it, and as to the beehive idea, im not so sure about that, a "regular" beehive probably has a higher surface area.... i've used one of surlyjoes "snailhives" ( a modified beehive) and it was VERY impressive

There is more to waterblock design than surface area my friend.

oh god lets hope kaitain doesnt see what you said jeff!

surface area is good, but also the less material its made of the better, really u just need enough distance between core and the deepest point in the blocks channels or wotnot so the heat can spread out more and so have more surface area being effective

I was speaking in terms beyond just base thickness. There are factors to consider such as fluid velocity, fluid entry and exit points, fin/pin/wall size/shape/thickness, and turbulator size/shape . . .
