Scythe Orochi CPU Cooler Review

[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

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

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


UPDATE!!!

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

[slugzkea]

Here are my first set of Pics...

2nd Set...

a line from Shrek comes to mind... " your a MONSTER!!!"

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.

[Digz]

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.

[melanko]

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.

900rpm fan will not cooldown da system. T-T

[decayed.cell]

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
OCZ GAMER XSTREAM 600W





Idle, no overclock, low voltage:


Prime95 for 10 min, no overclock, low voltage:


Idle, 3.6 GHz:


Prime95 for 10 min, 3.6 GHz:
BSOD after 7 min Prime95 with no fan at 92C.

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!
