Scythe Orochi CPU Cooler Review

[trans am]

Scythe has been developing large fanless heatsinks that employ heatpipes for quite some time. Their original NCU-1000 found favor with many silent PC enthusiasts. The follow-up, the NCU-2000, was an improved version of the same heatsink.

Their latest product is a massive tall heatpipe device with a loosely spaced fins structure. the Orochi can be used with all modern desktop CPU platforms. It is more extreme than anything Scythe has put out before. This innovation is definitely worthy to be classified as XTREME!!

Scythe heatsink designs have always been unique. The Orochi is by far the largest cpu air cooler on the market today.

BASICS

Thanks to Scythe for shipping the test sample fast.

What's inside the box?

http://i239.photobucket.com/albums/ff94/jackalsmith/orochi/5.jpg


You get 1 multi language manual, 2 cpu brackets, mobo backplate, 2 fan clips, thermal paste, and mounting hardware.

First glance
http://i239.photobucket.com/albums/ff94/jackalsmith/orochi/6.jpg

this is huge!!!!
It's bigger than my beer!

http://i239.photobucket.com/albums/ff94/jackalsmith/orochi/7.jpg

http://i239.photobucket.com/albums/ff94/jackalsmith/orochi/8.jpg

Look at that thing! I've seen single stage phase compressors smaller than this thing!!!

I put the fan on for a second

A WHOPPING 10 HEATPIPES!
http://i239.photobucket.com/albums/ff94/jackalsmith/orochi/10.jpg

This also uses a second heatsink that connects to the base.

The Base of the Orochi needs no lapping due to its beautiful mirror-finish! Look at the beer in the reflection!
Holy Crap! Totally Awesome!

Installation:

http://i239.photobucket.com/albums/ff94/jackalsmith/orochi/15.jpg
Turn the heatsink over and pick your cpu bracket. I'm using 775....duh. :rolleyes:

http://i239.photobucket.com/albums/ff94/jackalsmith/orochi/16.jpg


get it on and screw in 4 little screws. easy enough.

http://i239.photobucket.com/albums/ff94/jackalsmith/orochi/17.jpg

http://i239.photobucket.com/albums/ff94/jackalsmith/orochi/18.jpg

next get a motherboard and get the plastic bag off. I'm gonna be using an Asus P5K3 Deluxe WIFI.

http://i239.photobucket.com/albums/ff94/jackalsmith/orochi/19.jpg


This cpu socket area is tricky.. Will it fit?
http://i239.photobucket.com/albums/ff94/jackalsmith/orochi/20.jpg

YES!
http://i239.photobucket.com/albums/ff94/jackalsmith/orochi/21.jpg

I thought ram clearance might be an issue but you can see there is plenty of overhead from this image.
http://i239.photobucket.com/albums/ff94/jackalsmith/orochi/22.jpg

http://i239.photobucket.com/albums/ff94/jackalsmith/orochi/23.jpg

http://i239.photobucket.com/albums/ff94/jackalsmith/orochi/25.jpg

Installation was a breeze. You will need to take your board out because you need to mount a backplate on the mobo.

http://i239.photobucket.com/albums/ff94/jackalsmith/orochi/26.jpg



Fan clips are on and Fan is installed! 140mm FYI 500rpm so the fan is virtually silent.

Testbed and Methods


The testbed was configured as follows:

* Asus P5K3 DELUXE BIOS 0910
* Intel CORE2 DUO E8400 CPU (overclocked from its default 3.0GHz to 4.00GHz frequency)
* MUSHKIN DDR3 PC3-14400 memory
* VISIONTEK 3870 X2 VIDEO CARD
* Western Digital Raptor WD740GD hard disk drive
* MUSHKIN XP-800 power supply
* ARCTIC SILVER 5 THERMAL PASTE
* Windows XP with Service Pack 2

I used my living room to maintain stable environment temperature. As for the software, i used orthos small fft test and core temp.

I used a UEI DT200 to monitor the ambient temperature and certain areas of the cooler.

Fan rotation speed was set. At the maximum fan rotation speed of 2,000rpm using a Evercool 120mm.

Ambient room temperature maintained a constant 25c
The cpu temperature in idle mode varied between 41.5 C and 43.5 C resulting into the average of 43 C.

http://i239.photobucket.com/albums/ff94/jackalsmith/orochi/idletempsevercool.jpg
During 15 minutes of orthos load test (small fft) cpu temp was about 70c
http://i239.photobucket.com/albums/ff94/jackalsmith/orochi/loadtempsevercool.jpg

also note I have a bad e8400 that needs about 1.5v to reach 4ghz.


The results are especially impressive if we take into account the fact that Scythe Orochi has some room left for improvement, i.e. it has not yet exhausted all its reserves. For example, you can polish off the footing and thus gain a little bit more on the efficiency side. As for the faster rotating fan, I would recommend a higher rpm 140mm fan to cool the board and memory a bit better. The stock fan doesn't move as much air as I had hoped for but if you are looking for silence this is the best solution. The height is 20c with a fan attached. I never installed it in a case but my case (coolermaster Stacker) is 21cm. from the top of the motherboard standoffs to the side door. This is really cutting it close and you can forget about it if you want a side fan over the cpu area but I guess it defeats purpose since the fan is basically right up against the door. This is really meant for caseless setups or good for cold air benching.

On a scale from 1-10 I would give the Orochi a 7.

pros:
-easy to install
-nice base finish
-10 heatpipes
-cools pwm and dimms
-quiet operation with included fan

cons:
-too big to fit inside 99.99% of cases on the market
-considering it's massive size results were a bit disappointing
-included fan isn't powerful enough

I'd like to thank Scythe USA for the review sample.

[Nelson92]

any temp test?

[GripS]

any temp test?

My thoughts exactly... How is this a "review"?

Also how was the heatsink mounted? The retention mechanism appears to be the hook type instead of the push pin or bolt through method.

[trans am]

Yes sorry guys. i'm still working on the temps right now. just wanted to get some pics up in the meantime. hang on!

[Cybercat]

Ouch, 70 degrees load? Am I missing something? I realize it's running at 4GHz but isn't that a fairly typical OC for that CPU?

[cabbspapp]

I wanna see a 140x38mm fan on it.

[celemine1Gig]

If this thing fits under my NMB 172x150x25,4mm fan that is mounted to my case door, then it's as good as already ordered. :)

[awdrifter]

Is the 70c temp with or without fan? If it's with fan, that's pretty high.

[[XC] gomeler]

Wow.. my Scythe Ninja Rev B performs better with my E8400. This is more a preview though, need to include CPU volts and graphs :p:

[GripS]

70C for a dual core seems a bit high no?

You might want to include the volts that you are putting through the CPU.

I can't see why anyone would buy this thing if it really does perform that poorly. Imagine the temps on a quad.:eek:

[celemine1Gig]

Guys you don't seem to get the most important point here: The included fan is spinning extremely slow and that heatsink has a lot of surface to be cooled. This fan is more or less just there to have any air movement and not having completely passive cooling.
Slap a high pressure fan, that can pump the air thorugh all the fins, on that thing and then you'll have killer performance. ;)

[nosboost300]

any chance of trying something like a 100cfm fan? this seems like an interesting cooler and i'd like to know :)

[ownage]

Can you compare the Orochi with another heatsink?
Maybe you're e8400 has a bad temp sensor. Someone i know runs an e8400 @ stock volts and clocks with a Scythe Ninja, and the cpu still gets over 60c full load. Even after a few remounts.
It would be nice if you could test this heatsink with an old dusty 65nm @ 3.6ghz or something close.

LOL!! :rofl:



Anyways, could you put a high CFM fan on that thing and see how it goes?

[ineedaname]

what we really need is another heatsink on that CPU to compare it with. Then another run with a high power fan.

lol this made me piss my pants! hahaha! FIXED

[[XC] NetburstXE]

Very poor results considering the size. Even something small like the Arctic Cooling Freezer 7 Pro ($25 on Newegg, and much smaller than the Orochi) still performs better.

[hersounds]

so what thermal compound use?

look this...remember here in buenos aires is summer time,so the Ambient temps are high obviously but but look this frecuency and load temps with thermalright ultra 120 extreme and artic mx-2 anything lapped!

http://img166.imageshack.us/img166/5241/4horas41minutosrq1.jpg (http://imageshack.us)

so,orochi lose with TRUE120E?

[zfactor]

i have a feeling this cooler was intended on being mainly a "fanless" option or with the fan they give you. sure you can add 3 total but imo i think their intent when creating this was for a fanless type sink and if that fan was really moving a small amount of air as he said it was then the results are pretty good. i would say to get a fan that moves some serious air then compare the two the true and this.. tough call

[JaYp146]

Somehow, whenever I see this thing, it reminds me more and more of a Kol Battleship from Sins of a Solar Empire.

Anyway, yeah, this looks like a gargantuan spiritual successor to the Ninja; not designed for stellar performance with a fan. Rather, good for low airflow/passive setups. Oh, and GIANT CASES.

[nijel]

Got the Scythe Orochi. Here are some pics and a quick test, compared to Thermaltake Big Typhoon with Scythe KAZE-JYUNI "SLIP STREAM" 120mm.

[Power5]

^^^^ Nice comparison, that helps this thread a lot.

The Orchi with the Kaze is :shocked:

[L'enFer]

I think you should attach two or three high cfm 80 mm fans to make it cool better.

[Asgard_thor]

its alot of metal to move air through, I think more fans would better


someone should try 2 of the 220CFM Delta's

[miptzi]

absolutely grotesque
too big, TRUE still more appealing

[fragmasterMax]

This hs is really begging for some high speed fans. Without them it's no good for oc'ing. If i ever stop using h20, i think i might pick one of these up.

[slugzkea]

i installed my orchi today, and the temps were amazing. my e8400 at 4.3 1.56v prime was hitting around 56c, and that is amazing.

good air flow with tons of fans in my cosmos s rc-1100 BTW.

but...all of the sudden, my system failed. it will not boot. i get a half second of power and fan spinning and then nothing.

i've tried:

- disconnecting everything but psu cpu and mobo
- tried a different working psu
- put a anti-static bag underneath the mobo
- re-seated the orchi

all have resulted in no change.

blown motherboard (p35 neo2-fr)?

i just bought my pcp&c silencer 750w yesterday along with a xfx 9800 gx2 and i know it's not my 9800 so...i'm guessing mobo?

maybe if i put back my old zalman 9500led, and see if it truely is the orchi causing a problem with it's ockward sitting..?

i still think its a blown board but info and input plz! thnx guys :confused:

blown motherboard (p35 neo2-fr)?:

I would have said PSU but reading your post it seems you have tried using another working unit....I believe you may have actually succeeded in frying your cpu. From what I've read wolfdales are more voltage sensitive than conroes. 1.56v is a lot for a 45nm chip.

Do you have the possibility of trying another working motherboard?

P.s. it could very well be both: motherboard and cpu but you will never know unless you trie another mobo and at least rule out your cpu.

[fng77]

I agree. 1,56v is very high for a 45nm. I try not to go over 1.4v with my 8400

[slugzkea]

its not the cpu.

the wolfdales shut down automatically once it hits 70c, and i had very good cooling in my system. plus, after i installed the orchi, load temps on prime were 56c, compared to 70 wit the 9500led which resulted in shutdown.

it's not the cpu, and lots of people use 1.5+ volts to achieve over 4ghz

[slugzkea]

confirmed, its not the cpu :)

i bought a GA ep35-ds3p and it booted. thank GOD!

so anyone with a p35 neo2-fr, don't put a 9800 gx2 in it with a high oc comp!

the mobo capacitors can't take it!!! lol

[STEvil]

Do the capacitors look dead? Pics?

[slugzkea]

I'm not too sure, I'm not going to take pics because this thread is about the Orchi and not my board :) reguardless, the board died. It was a budjet board that had "platinum performance" but that was all BS and i'm the living proof.

a wolfdale running at 4.3ghz at 1.56v with excellent air flow and safe temps + a 9800 GX2 (oc'ed as well) blew the board. the ram was slightly oc'ed as well.

--------------------------------------------------------------------------

BACK TO THE TOPIC!

I have successfully installed my Orchi, and I'll post pics soon. Here's my Little review:

The orchi to me isn't just a CPU cooler, it's also a RAM cooler and a northbridge cooler. I thought by judging the components that the installation would be a breeze, but it was not.

The installation was Hellesh. The screws screw upwards from behind the motherboard, through the backplate and into the brackets (kinda like a thermaltake design, which is crap if you ask me, and highly frusterating).

Scythe also didn't include any extra washers or screws so if you loose one, you're screwed! I lost one washer, and was looking on the floor about an hour when I finally realized it was still on the mobo LOL!

Once the brackets and back plate were installed, the rest was pretty easy. The manual was bloody useless. They don't include any specific details which are crucial and I'll get to those later.

So like I said, this thing is huge. HUGE!!! I have the cooler master cosmos s rc-1100 case, which is possibly the biggest case on the market right now, and it barely fit into that! I had to remove my 200mm side pannel fan in order for my side pannel door to close, that's a piss off.

Oh, and don't bother trying to install the Orchi while your motherboard is in it's case. You won't have the room to get your hands in there to clamp those latches. Install the cooler on the motherboard/cpu while the motherboard is completley OUT of the case. I had to learn the hard way.

Also, the fan cannot be installed ontop of the cooler otherwise my side pannel would not close.

So, Side fan can't be attached, CPU fan can't be placed on top, crazy installation....was it worth it?

....YES!!!!

my e8400 at 4.3ghz 1.53v on prime95 reached a load temp of 56c

that is AMAZING! once again I have very good air flow, and 6 antec tricool fans blowing in.


OVERVIEW

Pros
- Amazing performance under load
- 10 copper heatpipes is every OC'ers dream!
- Cools RAM and NB as well
- a REAL MAN's HSF!

Cons
- Requires good airflow for maximum results
- Hellesh installation
- Useless manual
- Screws Strip super easily
- No extra hardware (washers, screws)
- Cooler can't be installed while the motherboard is in it's case
- Fan will not fit on top of cooler if you want your side door to close
- May not fit in most cases, and some motherboards
- Stock fan doesn't push enough CFM, and the clips for it are incompatible for other fans.

RECOMMENDED FAN FOR THE ORCHI: Antec TriCool




I shall post pics very very soon :D


UPDATE!!!

Currently at 4.5ghz, 1.65v. Idle temps are 41, load 53-60c

[[XC] Synthetickiller]

Slugzkae, thanks for the info & pics.

These e8400 insane to crazy speeds on air and this seems to be the perfect cooler. I know you said there's barely any room to mount it, but do you think it would have enough space in a MM duality? I have a q6600 @ 3.6ghz that is albeit, fast, but wouldn't perform as well in most instances as the e8400 @ 4.0ghz +. Since water cooling is expensive, I was thinking this might be a good alternative since the duality is huge and has good airflow. I was thinking of dropping 2 San Ace Sanyo Denki's on top of it (since I would have the head room) and see just how cool I can get that cpu.

Any thoughts?

Slugzkae, thanks for the info & pics.

These e8400 insane to crazy speeds on air and this seems to be the perfect cooler. I know you said there's barely any room to mount it, but do you think it would have enough space in a MM duality? I have a q6600 @ 3.6ghz that is albeit, fast, but wouldn't perform as well in most instances as the e8400 @ 4.0ghz +. Since water cooling is expensive, I was thinking this might be a good alternative since the duality is huge and has good airflow. I was thinking of dropping 2 San Ace Sanyo Denki's on top of it (since I would have the head room) and see just how cool I can get that cpu.

Any thoughts?

What's an MM duality? I know it won't fit in the antec 900 with the side door on, hell my case won't even allow the side door on, as you can see in one of the pics, the orchi comes VERY close to the side door clamp bar at the top.

If you want to aim for high clocks like my system, make sure you have the mobo that can do it. I tried 4.5ghz on my p35 neo2-fr and it couldn't do it.

But the GA-EP35-DS3P board seems to be the best P35 board out there for high oc and good price.

Room temperature is everything, make sure your ambient isn't too warm (use A/C or OC high in winter) :)

EDIT:

Okay I know what a MM duality is. I really doubt it'll fit man, the fuggen thing is hulk size.

wonder how this compares with a Thermalright IFX-14 with a fan running at 500 to 600 rpm for both temps and noise.

I've been looking at the few reviews that are out, and I don't think it'll come close to pairing up with the Orchi.

It has a non flat base issue, like almost all thermalright heatsinks do (exacto blade test).

I say the TRUE is still the Orchi's rival, or vise versa

[Digz]

Only thing thats putting me off the Orchi is the clearance around the Northbridge.

If you've never actually handled this monster it's hard to grasp its weight and size. Petra included this heatsink in his Air Cooling Round Up.

Got the Scythe Orochi. Here are some pics and a quick test, compared to Thermaltake Big Typhoon with Scythe KAZE-JYUNI "SLIP STREAM" 120mm.
The system:
Q6600
Gigabyte GA-P35-DS4
Patriot EP 4 x 1GB DDR2 800
BFG GeForce 8800GT OC2

Nice comparison but why is there 3576MB of RAM free in the 3.6Ghz Prime95 screenshot for the Big Typhoon and only 2475MB free in the screenshot for the Orochi?

I didn't notice it then, but later I did and resiting all four RAM modules fixed it. Changing that big of a coolers doesn't go smooth sometimes...:)

[slugzkea]

Hey guys, I took some pictures of how much RAM clearance there actually is under the orchi.

Most have probably predicted that you would have to take the orchi off to install RAMs, well the truth is there's actually a finger's space left between my vipers and the orchi.

It was a lil tricky to install the rams without taking off the orchi, but it was do-able :)

[Catz]

How many fans will fit on this cpu cooler? (like without to much diy ;))

[tiro_uspsss]

does anyone know if the Scythe Orochi fits in a CM690? cheers!

[fragmasterMax]

ALRIGHT :banana::banana::banana::banana: IT I'M GETTING ONE
SLUGZ YOU'VE GOT ME CONVINCED
LETS HOPE MY NAKED E7200 WILL BE able to handle this thing.

TIRO- I'Ve got a cm 690,so i'll let you know.
these are going wicked cheap right now (http://www.newegg.com/Product/Product.aspx?Item=N82E16835185064R), i guess i'll forgo a true........

So, i recieved my orochi yesterday. Everything was going great until i looked at the mounting system. The mounting bracket was to long and couldn't be modified, so genius that i am decided to attempt a "capaciter relocation mod" where i would unsolder the caps from the front and mount them on the back of the board. After i removed the caps, i had to bend the bracket a bit to ensure there was pressure up against my de lidded e7200, and the brittle chrome plated shiiit broke! So i then spent the next 5 hours turning the back plate that they gave into a bracket. (it involved lots of drilling, and cutting, but in the end it worked great. I'm a little embarrassed about the cap removal,(which wouldn't have been necessary if i had just done the bracket mod) and it was a bit obvious that with my puny 20 watt soldering iron, they weren't going back on the board. So after i fashioned the bracket, i decided to test it anyway, and the board is still alive!!!! This ds3l is missing a total of 5 caps, has the vdroop hard mod, and one of the coils has it's plastic box thing partially broken off, and a motley bunch of heatsinks cover much of the top. Now all i need is the nbcore mod, and the fsb will be flying!!!

As for the orochi temps, i could not be happier. This is replacing a scythe infinity, which was giving me 83 Celsius degrees at full load. This tops out at 60 after about 30 mins and then raises along with the ambient temps. With EIST on, my idle temps are 28 and 32 degrees!

It fits in my case, a cm 690, but don't plan on mounting any fans on the inside of the case.

Well guys, I decided to replace my Orochi with a OCZ Vendetta 2. You can check out my Mini review HERE (http://www.xtremesystems.org/forums/showthread.php?p=3420904#post3420904):)

My cpu kept crashing, and I was fearing that the brutal weight of the Orochi was possibly causing my board to warp, or dent my cpu, or something. My temperatures kept going up...prolly due to dust, who knows.

I strongly advise that whoever is using an Orochi to have the gravity towards it's advantage. What i mean by that is, make sure your motherboard is flat on a surface is not in a tower position. The thing is just too damn heavy.

Also, when i removed the Orochi, I noticed that half the base wasn't even incontact with the CPU! fresh thermal compound (as5) wasnt' even smudged or attached to my Orochi! No wonder there was such a difference between the two cores in load temps, jeez.

Anyways, it was fun to experiment with. But technology is prooving that these days, bigger does not mean better.

yeah the included mounting is crap, but i guess the two lateral pieces of metal acts as struts, and absorb the weight the of cooler.
Anyway, the soldering from the fins to the heatpipes also sucked, but this is still a great cooler. it just needs extensive mods to really squeeze the efficiency out of all ten of those long heatpipes. I'm going to grind off most of the base pretty soon, b4 i do an i7 install. This should definitely be interesting. Will update accordingly.
