This bunch of neatly arranged copper rods caught our eyes at Computex. Called the "Blonde Hedgehog," the exhibit below is a new heatsink design concept, in which numerous copper rods bunch up inside a ring, which makes up the base, where they make direct contact with the CPU, and fan-out towards the top. A fan then ventilates the bunch. The copper rod design ensures extremely high surface area for dissipation, the down-flow of the air cools other components surrounding the CPU socket, as well. The rods are held together by pressure, and not welding. In fact, the designers are bragging about the design being weld-free.

Warm Tek has two variations of the design, the standard one, Blonde Hedgehog C120, has exposed copper rods, and measures 140 x 140 x 90 mm, utilizing a 120 mm custom-design fan. The exposed copper rods are put through anti-oxidant treatment at the factory. There's a variant with nickel-plated copper rods, too. Another, slightly different and smaller variation of this, is called Baby Hedgehog, which measures 90 x 90 x 30 mm, and is meant for low-power CPUs.

That's awesome, I want one.

Now they need to figure out how to mash together 100's of heatpipes the same way, rather than solid metal rods ;)

Blonde Hedgehog C120, has exposed copper heat pipes

Is that correct?

Either way i would like to know these perform and if there are no heat pipes then they should get working on the heat pipe version.

Also I am curious if it could be used passively on a low power CPU as i love the look and it may fit in my HTPC, although possibly only without the fan.

I was about to say the same...although I cant quite figure out why, could it be that it might have to do with heat not being properly moved away from the rods since they are positioned that way? Plus the base of the heatsink seems to have a very uneven surface, far from mirror flat with a lot of micro-holes that won't perform great even with excelent thermal paste (too many micro air-bubbles)

So what happens as it slowly packs full of lint and dust? As you try to clean it it pushes the debris further into the rods.

Plus fans have little to no flow at the center due to the motor, and this cooler provides little in the way of airflow directing to help cool the hottest part of the CPU.

Perhaps for a "look" build, but certainly not for a serious performance build.

are the rods randomly standing around? or is there a certain structure/design to it?

They did a bi-variate scatter plot of the people who think it's cool by the people who think it's efficient and came up with the rod placement. lol

Old design is old, and not very effective compared to heatpipe + aluminum fins.

If these were all mini heatpipes somehow it be a great new design.

(old design is cool though I wouldn't mind one)

we have brushes like that bottom one at work. THEY GODDAMNED HURT WHEN YOU STAB YOURSELF WITH THEM.

these heatsinks will cause a death one day.

So what happens as it slowly packs full of lint and dust? As you try to clean it it pushes the debris further into the rods.

Plus fans have little to no flow at the center due to the motor, and this cooler provides little in the way of airflow directing to help cool the hottest part of the CPU.

Perhaps for a "look" build, but certainly not for a serious performance build.

never heard of a dishwasher? besides from the look of it the rods can be pushed around by airflow (it's the only way i see the hot air escaping successfully) so a standard air can would work.


are the rods randomly standing around? or is there a certain structure/design to it?

It looks like they simply pressure bunch them at the bottom and the rods naturally flow outward in a circle. In order for it to work the cooler would need to be a bit more flowing than rigid so there likely isn't too much they could do to force them to stay where they are boyond the placement of the longer ones on the edges vs the shorter ones in the center.

Family: So how did he die?
Detective: We think he was killed by his computer.
Family: What! How?
Detective: Well it looks like it tripped him with the power cord and then the computer stabbed him with the heatsink...
Family: I told him not to do all that stress testing on his computer...
