Scythe Readying Big Shuriken CPU Cooler

Friday, May 29th 2009

Japanese cooling specialist Scythe is readying a new variant of the Shuriken CPU cooler, this time of a slightly larger built, while respecting its design ideology that it should be slim form-factor friendly. The Big Shuriken differs from Shuriken in its dimensions, fan size, and number of heat-pipes. It measures 125 × 135 × 58 mm, and holds a slimmer 120 mm fan, in comparison to the Shuriken having a 100 mm fan, and a height of 64 mm, which is slightly higher.

The basic construction remains the same: from a CPU contact base that doubles up as a heatsink, originate four copper heat-pipes, that convey heat to a dense array of aluminum fins, which is directly under the air-flow of the fan. The PWM-controlled fan spins at speeds of 650~1600 rpm, pushing 15.77~38.05 CFM of air, with noise outputs ranging in 12.91~28.89 dBA. The cooler weighs in at 405 g (around 0.9 lbs), and is compatible with most existing desktop CPU sockets including LGA-1366/775, and AMD AM3/AM2+/AM2/939. There is no word on its global availability and price yet.

Is that the Zotac Ion in the last two pictures?

No, it's their LGA-775 GeForce 9300 ITX.

Yeah I just checked. Nice cooler mind.

It's huge....No tall RAM please :P I'd love to see how well it performs, from the looks of it it'd add airflow over the MOSFETs :)

CPU, ram, NB... one cooler to rule cool them all. If i was going mini ITX, this cooler would be on my list for sure. it solves 99% of the cooling issues you get in those systems, assuming height is not a concern.

You know I have the Mugen and the Mugen II, the Mugen 1 works better, and with the MII fan it is even better yet, plus the MII is ultra heavy.... why mention it. Because they are not using copper bases anymore, and I suspect a lot of the new coolers may not be so great.

Looks like they are showing it on a mATX board... was surprised that it's just a 120mm fan, and the dimensions are only 4.5" x 5". Would be great to see a version with a 200mm+ fan on it, and taller - would work like a champ to cool the entire board.

with only a single expansion slot, thats itx, not matx. if the fan was any bigger, it'd block your expansion slots.

That motherboard looks like it is bent in the middle.

I like it! In fact, I was hoping to use that board in my NES project.

OK, I never really understood how these things work so about a week ago I did some research. Apparently, the pipes are filled with some sort of inert gas. The cooling happens as the gas is heated, moves up the pipe, dissipated by the heat fins and then sinks back to the bottom again. It's the same way old-style radiators work. You send steam up the pipe, it releases heat at the radiator, condenses, and the liquid water then drips back down to the boiler. However the trick with steam radiators is that the pipe runs have to be on a slope, otherwise you get water pooling which then blocks the flow of steam. Now since there is no phase change with a gas - just different temperature gradients - do you still need the pipes to be on an angle? Or are you just relying on the gas expanding and contracting? Either way though, it would seem that having heat pipes exactly parallel to the base would reduce the efficiency of the heat transfer. Right? Or have I got this all wrong?

Yea, I think you're right. Did they do that to make it look gigantic, or a possible HTPC solution? If larger, offsetting the thing could solve clearance problems.

I've wondered the same thing... if the pipes aren't sloped right, is it less effective?

There still is a phase change with a heatpipe. Here is a good diagram of how a heatpipe works:

Becuase a wick is used to transport the fluid back to the hot end, orientation of the heatpipe does not matter.

i cut open some heatpipes on a thermalright cooler recently for the heck of it, and its not open air inside. they had this... moist coppery powder inside. not all heatpipes are created equal!

This is very true, some have not wick at all, and do require gravity to work. These are usually found on cheaper coolers, where the heatpipe is only there for show mostly.

i got one of these

and broke it in half, so i could use it on my DFI board where the CPU heatsink was conflicting with it. It was almost solid inside, i can only describe it as "moist coppery powder"

Just listed in Japan @3,570 yen (26 euros)... Great cooler for a power HTPC rig.:rockout:

Holy Crap that thing is huge, talk about an almost all board cooler.

Wow a really nice low profile solution that can cool RAM.

hey im REALLY impressed with that somones always thinking right?

The moist coppery powder is the wick. A wick is just a material with small gaps in it so that surface tension/capillary action is maximised.

this is cooling the hole mobo , nice

by jamesrt2004 (6:48 AM) - Reply

do people not understand how small mini it is :S??? this cooler isn't that big at all it just looks it cos' of the mobo' it's on. If it was on a mini atx or atx it would just look..... normal :) great cooler though Im looking into building a nice mini itx system and this will fit the bill greatly

the fan IS acualy big and the system IS acualy mini ;) its a great idea to have it reach all the way down like that.
