The Scythe Ninja is officially THE MOST ANNOYING HEATSINK TO PUT ON. Were the instructions translated by a fucking 12 year old kid in Malaysia?!?!?!? (Probably). But man on man, it is annoying. About to go test right now. Oh, btw, its enormous.
 
Update!

I told it that it's going to hell.

But quite amazing results.


With Zalman 7700Cu: Idle: 36C Load: 43C
With Scythe Ninja + Fan: Idle 28C Load: 35C


That's quite a difference.
 
Please don't make thread titles like "Holy Mother of God".

Thread titles should be descriptive and not involve brash religious references that are irrelevant to the issue. Umkay?

Its not that difficult
 
its not hard to put on...but i thought i was going to break something when i had mine.
i sold it promptly.


the ninja is not made for uncapped cores btw ;)
 
Sorry about that Lethal, forgot :rolleyes:

QFT, I thought I was going to crush my CPU lol, you really need a lot of force to put the clips of the HSF to the retention bracket.
 
I just put mine on a couple days ago and wasn't a fan of the mounting crap. The backplate is metal (ok, so it has a thin layer of foam). You could potentially short something out with it, although it's unlikely. The adhesive didn't help it stick to the board. It was slightly curved, so it didn't lay flat against the board until I cranked the retention bracket down from the other side. Then as has been mentioned, the four retention clips work, but aren't the easiest thing in the world to clip on. I even had a somewhat hard time clipping the fan onto the heatsink, since the little clippy things are thin and like to bend themselves out of the grooves on the side of the ninja.

I got it all put together and fortunately, it cools well. Heatsink design, good. Various retention designs...eh.

I agree 100%. Wasn't it scary with the four clip things? Didn't you think you were going to crush your CPU?

Wish my temps were that good. Idle ~40C. :-/

That doesn't sound right....I'm running 27-28C idle and 33C load.... granted not dual core, but that sounds odd. You did only use a tiny bit of thermal paste, yeah? If you've remounted it and you get the same temps, I'd venture to say that your diode is off.

Either way, I really didn't find it to be THAT big of a deal to get the thing on. A couple of screws here, replace em with another set of screws, slap that fucker on the top and press down the clips. TBH, I don't think that instructions were even needed as most of it was truly just common sense as to whats supposed to happen where.
 
is it harder to put on than the zalman 9500? What im asking is for someone who hasnt installed a hsf before, what would you reccommend?

I'd say that they're probably both about the same difficulty, because with both of them there is a chance you'll need to remove the motherboard and change out the bracket (the biggest job of all of it). It seems that some people have trouble pushing clips downwards to install the Ninja, but not only did I not have any issues, but neither did these guys or these guys or these guys . In fact, SPCR even made mention that:
The Thermalright XP120, the Zalman 7000/7700, Scythe's earlier models — all were more trouble to get on. The Ninja was much easier.
Meanwhile the zalman screws into the mobo, which is also simple and easy to do.

Morale of this story: It's going to be just as easy to install either, as they share the hardest part (replacing a mobo bracket if need be).
 
I agree, the instructions were not needed. I thought that I might snap my mobo though with those clips. Snap it or crush my CPU lol. I was hoping if something happened, it would be my mobo :rolleyes:
 
i thought you had to remove the mobo anyway. I have a removable mobo tray so it shouldnt be that hard, right? Also, if i do remove the mobo, should I take off the hsf that will be installed on it already, remove the grease, add as5, install the 9500, and then add the mobo back in with the 9500 already on it?
 
Yes, most heatsinks except the ones that clip into the retention bracket (stock HSF) you need to remove the mobo and add the backplate. It isn't that hard, but it can give you a backache (at least it does for me because I work on the floor, bad idea).

I'm not sure about the 9500, but I know that the ninja fits on some stock brackets.

As for installation, It's a better idea to remove the HSF with the motherboard still screwed into the standoffs (I find it easier that way). Once you've removed the stock HSF, remove the motherboard, clean off the old paste (with rubbing alcohol and a lint-free cloth), and unscrew the stock bracket. Install the new bracket, add a DROP of AS5 (if you doubt how much to add, follow this picture and these instructions starting at #9 if you get lost). Now install whichever heatsink you bought, and slap everything back in your case. boot up the puter and enjoy your oc'ing headroom :D
 
I find Zalmans to go on easier than the Ninja. Ninja was a fucking pain in the Butt.

i read that, is it bad if i use something other than my heatsink to spread the arctic silver? my friend used something flat to spread it

let me know, i'll be doing it on my own this time :) muahahaha

go 9500!!!
 
Ahhhh the age old question: To spread or not to spread?

I usually just drop the AS5 on the CPU and then mount the heatsink. It spreads itself and in every direction. I fear if I spread it myself I'll make tiny air pockets or bubbles and THAT, my friend, is bad.

hm, i'll try that :) i'll post my results and if they suck i won't love you :p

lol

The best way is to experiment yourself. If you find a better result with either method be sure to post back - I'd be interested. The whole "air bubble" thing has me spooked to no end 'cause I don't want me multi-hundred dollar CPU burnin' itself out.

somone do them both and post back here asap please
i don't get my 9500 till thursday :( i'll do both for fun and post my results

1 day just a dab, the next spread

It's already proven that using just a small dot is the best way to apply thermal paste, as not only does it ensure that there are no bubbles, but it also allows for the thinnest coat. Search around the forums a bit if you'd like, but I guarantee that you'll get better temps by only using a dab of paste.

Also, to whoever was worried about killing a cpu, just by spreading the paste you won't fry your CPU, you just won't get the best temps.

You'd probably be surprised to find more chances of air bubbles if you do not spread it. After I install my heatsinks, I always rotate it a bit, both directions, to smooth out the AS5 between the CPU and heatsink. Just a thought. Oh and I use my plastic smoother that I still have when I used Nanotherm. A razorblade works well too.

its proven that not spreading the as5 and just leaving it there for the weight of the hsf to spread is the best way?

yeah, and as the post just above mentioned, twist the HSF say 15 degrees either way and then install. its the best!

I wasn't really too worried about crushing the core(s) since the heat spreader seems pretty sturdy. I was worried about getting the heatsink lined up right though, because the fresh AS3 between the Ninja and CPU made things a little slick, and it was hard to only push down on the clips without getting any sideways motion going. Eventually I got it pretty well centered and got a pair of clips on opposite corners to click in, and that held it ok so I could push the other two down.

It wasn't OMGHARD! to get the 4 clips into the retention bracket, but it took a lot more time and effort than the stock AMD heatsink had.
 
Yeah, but I must say that the results are E-Mazing. Okay stock voltage for X2 3800+ is 1.3V I believe. That idled at 25C. I upped the voltage to 1.5V (To cure the AS5 and because my chip OCs to 2.9Ghz with 1.5V). It idles at 34C!!!! Load at 42C. That is pretty amazing. I guess it is also lucky that I have a true Manchester core and not a half cached Toledo because the heat output is enormous

Manchester: 89W
Toledo: 104W


Right now I am running at 2.8Ghz @ 1.5V
 
My idle temps are higher than your LOAD temps lol. I know it can't be running that hot. I heard Asus boards read high so I'm not worried.

that sounds right. btw, nice rig you got there!

i didn't find the Ninja too tough to install -- but i'm glad to hear yours is on and the temps are sweet.

besides, what fun is there in doin' things yourself if there isn't a little fear involved. that's what makes it fun! :eek:
 
Different core, different wattage.

Opteron has heat output around 102W

X2 Manchester has a heat output of 89W

Big difference.
 
Good. Thought I was doing something wrong here :D Totally stable rig so I wasn't too worried. :cool:
