bad Ninja Plus RevB AM2 mounting?

Techno Pride · Post by **Techno Pride** » Thu Mar 08, 2007 5:46 am

Hi, I've just gotten a new AM2 system plus the Ninja. My previous setup was a SocketA mobo with the Zalman 7000A.

I can't help but notice the dumb installation method on the AM2 system. When you hook one side of the clip, the ninja will lean over to that side until you secure the other side. Will this affect the thermal paste spreading? I put 1 drop (rice grain size) of Arctic Silver 5 onto the IHS.

The Ninja also barely feels warm to the touch after 2xBurnK7. It still manages to keep it at 51c though. After taking off the Ninja fan, the max temp rises to 57C. But for a ~35w processor, that still *seems* kinda high.

Setup as follows

x2-3600+ (Windsor, 2GHz, 2x256kb, 1.05v)
Ninja w/ D12SL-12 @ 5v
Abit NF-M2 nView w/ integrated GF6150
Antec Sonata (2x D12SL-12, front 5v, rear 7v)
FSP Bluestorm 350w (fanswap w/ 1200rpm max fan)

room temp is ~29C. any ideas if there's bad mounting?

My guess would be either not enough pressure between the cpu and the base of the heatsink, or the sensor is reporting a faulty temperature. What are you using to measure the temp? Try Core Temp.

Hello,

If you open the side, does the temperature improve? Have you modified the front intake on the Sonata?

hi,

I'm using AbitEQ utility and Core Temp to read the temps. Both give the same readings.

I've tried removing the side panel. The temperature does drop from 57C to 55C. The only "mod" i did to the Sonata is to remove the front filter. I've 2 HDDs mounted in front.

Anyway, I've removed the Ninja to see how the AS5 is spread out. The layer of AS5 seems to be *too* thick, which points to the heatsink not applying enough pressure on the IHS.

I've worked with AthlonXP(bare core) + 7000A and Tualatin(IHS) + Thermalright SK7 and in both cases, the AS5 spread was perfect with a very thin layer.

Even though 57C still seems to be a safe temperature, it's still too high for a ~35w processor. I'm thinking of bending the Ninja's AM2 mounting clip so that more pressure can be applied.

Techno,

Any progress on AM2 Ninja 1100 setup?

I ordered a similar setup 3600+ Brisbane, Ninja 1100 and AS5
that I will build soon.

Any others have tips on this setup?

thermal sensor or program might be bit off too. I have abit A8V-MVP and Abit's own program reports my cpu temp: 33, 51 and 60 degree's C it rotates those figures in 10 second cycle. So I use SpeedFan for checking temperatures.

Hmmm, I don't think Rev B's AM2 mechanism is that bad. You might have contact problem due uneven base, which lapping would solve. Or then its just bad program for measuring temperature as Asus or Abit's program are not as good as SpeedFan IMHO. Or then temp sensor is faulty, like my old Via board, my 3000+ sat steadily on 44 or 47 degree's idle. And never got passed 52 degrees on load. so 8 to 5 degree rise betwene idles and load suggested it has faulty sensor. ( temps were with C'n'Q )

You seem to have a bit too much Artic Silver on there,you should not rely on pressure to squeeze out the excess.

While there's frequent hassles mounting to a Core 2,usually AM2 mounts okay.

What is your ambient temps?

krusty · Post by **krusty** » Thu Mar 22, 2007 2:24 pm

Just got my Ninja 1100 and the bottom surface didn't look good.
Some residue left from the plastic cover on the base. Might just be oxidation but when I did a fine lap, I can tell the edges are high. You can see the Triangle image from the plastic cover on the base, but that could
be oxidation.

Maybe that's preventing the AS5 from spreading on yours.
MAybe your edges are high.

Also, I think adding a touch of AS5 or Silicon Compound
from the heatpipes to the copper base might help,
provided the base is flat to begin with.

I'm gonna lap mine. It's awkward to hold though.

I can't believe you people... When did 57c become a bad temp for a dual core processor running a burn software? I remind you, this is with passive cooler and his room temperature is 29c. If someone really thinks there's something wrong in here, he needs to get his head checked. It's a cooler for crying out loud, not a miracle machine...

Its not a bad temp, but I would expect better temps when your talking about an undervolted 65nm chip.

My stock Ninja 1100 was not flat.

After lapping my Ninja 1100, I can now see my bloodshot eyeballs in the mirrored finish of the base.

I used 180, 400, and 1500 grit sandpaper.

A four beer lap job

I also applied a bit of AS5 from each of the 12 heatpipes to the copper base.

Will post temps and maybe overclocking this weekend on my
Brisbane 3600+...

For running a burn program, these temps are fine, i thought he said they were idol.

Hi all, thank for your replies.

I took off the ninja and the outer edges have scratch marks. This shows that either the IHS or Ninja (or BOTH!) aren't flat. I've cleared out the AS5 and used applied ShinEtsu all over the IHS, but temps seem to be the same.

I'm fine with the temp, though it just feels weird that a sub 35w processor would run at that temp passively. Or maybe it's just my crappy ver1 Sonata. BTW my processor's 90nm, not 65nm.

Here's a sketch

I don't how well the stock press fit transfers heat from the base to the
heatpipes so my thinking is adding some heatsink compound from
the SIDE of the base to EACH heatpipe ensures some heat is
transfered to EACH heatpipe. It can't hurt IMO.

I agree the AM2 mount makes it IFFY at optimal placing of the heatsink compound.

Also, after lapping my Ninja, I did a quick fit check without AS5 and
got a faint mark in the middle of the IHS. When I did test fine test lap
on my Ninja, only the edges were touching.

I eventually used about a BB sized AS5 in the center of the AS6.

It looks like your 90nm 3600+ is good for about 70c, so if your 55c temps
were at load, you should be OK.

I'm running 34c at idle, but have a very low flow & low noise setup - Brisbane 3600+ Fanless Ninja, but the 140mm 5v PS fan sits about an
inch above the top of the Ninja. No case fans. A second 140mm 5v fan
cools a 7600GT AGP (I unplugged the noisy stock 7600GT fan).

Cheers!
