Temperatures Q6600 and Ninja Rev.2

[parkgarage]

I don't have a thermophobia, I just want to make sure, that my Ninja is installed correctly and the I get the maximum out of the cooler. Now if read correctly your statement, Ryan:

With a Vcore of 1.3750 (9*300) you have temps in idle at 37-43 and exactly here is what I don't understand, as I have a Vcore 1.22 (9*333) and have idle temps of ~40°, i.e. much less Vcore, Q0 and still close to the same temps as you have.

And I also think, that if I want to OC 9*355/Vcore 1.29 with the Q0 the temps shouldn't be at 70° under prime load. So my guess is, that there must be something wrong with the cooler or with the thermal paste I applied or just the whole installation or I may have bought the wrong cooler...

My goal was and still is, to have a stable 9*355 with a quiet set-up, i.e. the fans shouldn't do more than 800 - 850 RPM.

Next step is, that I will take off the cooler and apply the thermal paste again, this time according to the instruction of Arctic. Let's see if this will work out better, if not I'll have to go for another cooler...

You assume 70°C but if that will happen is not sure. You should check the imprint of the base on the cooler because that shows if you applied the thermal grease right or not. It might be the thermal grease, it's the medium to improve the contact of both components.

What RPM do you have now? You should be possible to improve it if you try it

I took off the cooler and applied again the thermal grease (this time much less) according to the instructions from Arctic.

Then I've installed a second fan on the Ninja for a push-and-pull airflow towards the back of the case where there's anoter fan pulling out air.

Fan/Case set-up
Ninja: 1 x 1300 RPM blowing air / 1 x 800 RPM pulling
Case (all fans at 800 RPM): 1 x top pulling, 1 x back pulling, 1 x front pushing, 1 x bottom of the case directed towards to the PSU pushing (the PSU always stays cool and quiet)

The push-pull set-up on the cooler and the newly applied thermal grease only gave me an improvement of 3-4°, which is not much considering the set-up. Under prime load @ 9*355/Vcore 1.29 the 4 core are now at 62-67°
Improment at idle is even less (1-2°). If I lower the RPM on the pushing fan at the cooler also to 800 RPM then the temps are over 70° on full load.

So, I belive I've done everything (beside lapping the IHS) to improve the temperatures and my assumption so far is, that the Ninja is not made to cool OC processors, but is excellent when it comes to have a quiet non-OC set-up. Maybe I should switch to another cooler for that reason. I've seen other reports and tests, cooling down a Q6600 Q0 to below 50° with a OC of 9*333 or higher (not water cooling).

I recently switched to a thermalright 120 extreme, gave the same temps as ninja. and took alot longer to return to idle after loading.

now back on the ninja, my bros getting the tt120e for his e4400.

Good luck!

That's not surprising: Ninja is a low-impedance heatsink so there's not much sence in increasing pressure.

What's wrong with 70C if it doesn't cause stability issues?

as we have said, and from what I posted on this very thread, here is the temperature scales for a g0 quad:

Scale 2: Quad
Q6x00: Tcase Max 71c, G0 Stepping, Tjunction Max 100c, Vcore Default 1.372, TDP 95w, Delta 10c

-Tcase/Tjunction-
--70--/--80--80--80--80-- Hot
--65--/--75--75--75--75-- Warm
--60--/--70--70--70--70-- Safe
--25--/--35--35--35--35-- Cool

see that 70 is in the safe range? yes? enough said really.

70c is safe.

Hi,

You can only improve a bit, but the Ninja is basically for silent use, OC is best with Mugen. As the other guys said, below 70°C should be fine, maybe you want to use the normal thermal grease. Every time I hear complains about the temperature, it is Arctic Cooling thermal grease. I wonder if there is a change if you use the normal silicon thermal grease. Can you check that?

[parkgarage]

After trying everything with the Ninja, I decided to go for another cooler. So I bought the Mugen and just installed it. With exactly the same setup as written above with the Ninja the temps are now idle 7° / load 10° lower. In a few days, when the thermal grease has burned in, it will probably go down another 3-4°. My conclusion: don't use the Ninja if you want to OC your PC.

In a few weeks I need build a quiet server, I will then probably need the Ninja again for a fanless installation.

Ninja is definitelly not for OC.

[Shinigami]

Hey,

Well, Ninja is possible to give decent OC, but some people expect the wrong thing from it. I hope you are going to be satisfied with both coolers, parkgarage. Mugen is the OC Cooler indeed
