WTH ?!?!

They actually look efficient.
Wonder how they perform.

I like the FB-176

[Barney]

It's very efficient, but it doesn't cool (nearly) as well as the larger coolers. I think I saw it in one of the cooler reviews on Tom's Hardware.

I just read a review (http://www.cluboverclocker.com/reviews/heatsinks/zalman_coolers/index.htm) ... VERY POOR performance! It's "all show and no go"!

[Szech]

Ah, the Zalman flower. The concept is good (Lots of copper plates = lots of surface area), but I suspect that the angle of the fins at the edges make it hard for air to flow over them.

Mabye if the fan was on the side somehow blowing though not over?

[jadison]

very interesting, I haven't seen anything like it...are u sure it doesn't perform well? I see that it's not compatible with a heatsink fan http://www.sysopt.com/forum/smile.gif

hey, i just said that they LOOK cute.....

btw, thanks for the review link.... i still like them... they look soooo cuuute.... maybe we can use them to make silent pc's with out old cpu's (the below 300's)

They are made for quietness.
If you put a huge high CFM fan instead of the default quiet 80mm fan, I bet it wouldnt do half bad. Also, The position of the fan is farther from the heatsink than most fans, so the heatsink is only getting a small taste of the wind from the fan.
Fan position was probably the first reason that no one ever attempted to make a sink like this before.

What if you found a thin fan and sat it vertically in the space between the 2 rows of fins? Either that or mount a fan horizontally on it. It would work decent but not perfectly because of the odd shape of the HS. It seems like a fairly good sink though because of the incredible SA on it- lots of fins!

If you look at the install instructions, there is a fan on a bracket that attaches to the rear slot frame. Appears to suspend the fan over the cpu. This could be good if you needed quiet more than extra cooling.

Hey, wait a minute... did you guys check out the 21 cooler review that was linked off the main page here? check this out:

The Zalman flower kept a Duron 600 1.9V at 51C under full load... with no fan. I'm pulling a 180 on this one! http://www.sysopt.com/forum/biggrin.gif This heatsink is pretty nifty for passive cooling!

If you're going to try this with no fan, then I'd definitely advise a micro-thin coat of thermal paste - otherwise I promise you - you'll toast something.

Otherwise - get a fan and suspend it from the case with a bit of angle iron attached with liquid nails on an unpainted surface - then the thing should get downright cold.

Very inspired design, but I think it needs a plastic hood leading to a draw fan to pull the heat out.

Only problem I see is that there are some motherboards that seat the memory so close to the socket - or the IDE ribbons, that the fins could be a problem. You'd have to be really sure that the ribbon cables were rounded and secured back out of the way <<< they should be anyway for the sake of case air-flow.
