Scythe Orochi 10-Heatpipe 1.1Kg Super Silent CPU Cooler

jmke · 17th March 2009, 22:05

Day 3 of the Heatsink tests at Madshrimps brings the behemoth Orochi from Scythe to the test bench. This 1.1kg monster (1.25kg with fan) has no less than 10 heatpipes! It dissipates heat to a monster surface area which can be covered by several 120mm fans if need be.

You'll get a 140mm inside the package which spins at 500rpm; special thing about this fan is the mounting holes, which line up with a 120mm version, so you can use the included clips with any flanged 120mm fan you have lying around.

Compared to Intel's "larger" stock HSF:

Orientation is key with the heatsink, you can mount it every way you want, to avoid is having the heatpipes pointing upwards; for optimal airflow they should be point down; but the huge size of the Orochi prevents this from working out in many mainstream ATX cases. We installed it sideways, there's no room for the 140mm fan to fit on top (it exceeds the case width in that case) so we had to mount it at one of the sides. Good thing to know is that this fan is dead silent; you wouldn't know if it was spinning or not, unless you put your ear next to it. So golden rule: always use it with the 140mm at least; no point in using it passively cooled.

Our tests were done with the 140mm stock fan, as well as our reference GlobalWin NCB 120mm. Here are the results, compared to two other very quiet heatsinks from Scythe

compared to the stock Intel HSFs the main difference is the absence of noise

If you have room inside your case and want to have a dead quiet PC; this heatsink should be near the top of your list, its 10 heatpipes have plenty of cooling power to spare; the Rev.B of this Orochi will add Core i7 support; so that will be a hot potatoe you can almost passively cool down with this Scythe Monster cooler.

Is it alu or cu ? I'd say alu because of the dimensions and total weight

jmke · 17th March 2009, 23:16

base & heatpipes=copper; fins = alu
wouldn't want to imagine all CU

all CU would be great man :P

The density of cupper is 3 times the density of aluminium, a full cu Orochi would weigh about 3kg (and probably cost €150 or more)

and it won't make a big difference in CPU temps

no?
I thought that CU was a better conductor for heat than ALU?
(i could be very rong about this sow if you don't mind care to explain how come

)

nope; 2-3°C tops; contact area is where the action is at, and there it's already copper

nigel · 18th March 2009, 16:16

ah

hmm it makes sence in a way that where it makes contact that that is the most important spot

Every day we learn somthing new ^^
