New CPU cooler from Scythe, "Orochi"
http://www.scythe.co.jp/cooler/orochi.html
That's a lot of heatpipes. What a monster.
Designed for fanless or slow fan use, like the Ninja.
Tech stuff...
120mm x 194mm x 155mm (height)
140mm x 25mm fan, 500rpm (12cm mounting holes)
weight 1155g + 130g fan

Ninja's 10 is effectively 12.
Talk about equilibrium, it may not happen with 10 heatpipes. Ultra 120 has 4 (times 2 = heatpipes while TRUE has 6 (or 12), and we see... 6 degrees difference and higher overclockability.

And with the way the mass is distributed, the cantilever effect on a vertically-mounted motherboard must be horrendous.jaganath wrote:even with a backplate, i would never hang almost 1.3kg off my motherboard
Really, can't heatsink manufacturers come up with anything more imaginative than just throwing more and more metal at the problem?
If you scroll down the product page a bit there are some pics of one fitted onto a motherboard.
The problem with that cooler appears to be that the vanes don't line up with a typical ATX case exhaust fan. With this new "Orochi" the solid side of the metal vanes are facing the exhaust fan, unlike a Scythe Ninja where airflow from an exhaust fan passes through the CPU cooler.
Even though it's heavy that could negatively affect performance.

Especially if you have room for the 155mm HS and the 25mm(?) fan, at least 180mm total, even not allowing a space for the fan to get its input air.borc wrote:Looks like that's going to fix one of the problems of tower heatsinks: not enough airflow on the motherboard surface. The orientation allows you to place a fan on the top.
Obviously, this HSF targets the HTPC market.
The vanes do line up with the airflow for bottom-feeder PSUs though so it might be good in a configuration in which you use a single 120mm fan to cool the CPU and PSU.WR304 wrote:If you scroll down the product page a bit there are some pics of one fitted onto a motherboard.

This cooler is obviously not going to fit, or be 100% effective in all setups. So it's a matter of building a setup around the thing....unless you get lucky.
Plunk it down in an Antec 900 case, and you shouldn't need any fan on the heatsink. Coolers like this are not intended to fit every conceivable situation, but when setup properly, could be the quietest/coolest around.

actually I'm pretty excited about this. I think a lot of you are envisioning this thing hanging off of a vertically mounted motherboard, but in an HTPC/Desktop style case where the motherboard will be horizontal, the weight most likely won't be a huge problem.
The only thing I'm worried about is the overhang on the side of the motherboard. My case is almost flush against the mobo's edge on the side of the cpu socket, so if the orochi's footprint causes it to extend beyond the edge of the mobo I might not be able to use it.

There's a pic near the bottom of the Scythe product page of it fitted into a case. The heatsink is largely offset from the PSU fan, as the vanes extend to the right overhanging the memory. It doesn't look like the PSU would contribute much as it only covers some of the vanes.nutball wrote:The vanes do line up with the airflow for bottom-feeder PSUs though so it might be good in a configuration in which you use a single 120mm fan to cool the CPU and PSU.
That's not really the point though. If it works really well with little or no airflow I'm sure I'll end up getting one or two.
You could even have two in one PC: one for the CPU and maybe one for the GPU too.
It would be do-able so long as you used a supporting strut like the one yamahaSHO used with his Thermalright Ultra 120 Extreme cooler:

It can keep an E6300 (65W) cpu at 58C without a fan on an open testbed in case with some airlow it might be better, which is indicated by the fact that a store demos a rig with Phenom 9500 cooled by a fanless Orochi in Akihabara ( see bottom of the page).
