Ninja rev.B @ E6600 default - over 80°C under load

[Caderom]

Hi,
I have a problem a problem with cooling my E6600 at default voltage and frequency by Ninja rev.B. on Gigabyte GA-965P-DQ6. The temperature achieves over 80°C under Orthos load. With Intel BOX the temperature stops between 68 and 70°C. This problem I had with the original substance and have also with a few other thermal coumpond. When I try press the cooler down, the temperature fall down max. about 2°C. I cropped the edges because I had thought there was a problem with mosfets on MB, but nothing changed. It look like the cooler is defective. Have anybody some problem like this?

I'm going to buy a new Arctic Freezer 7 Pro because I use loud Intel BOX now. Ninja is in a drawer.

Hi Caderom,

Thanks for the detailed explanation of the problem with your Ninja PLUS.

I would like to solve this problem because it can actually not be that you have such high temperatures. Let's go over some possible reasons and solutions.

1. Have you used original silicon thermal grease?
2. The print of the CPU IHS was identical to the one on Ninja base?
3. The supplied fan is running at full 1200RPM?
4. Please list all components which youa re using in your system. In some cases the VGA card is heating up the environment and also has influences on othzer temperatures and heatsinks.
5. What is ambienbt temperature and the one in the case. Do you have any fans supporting an airflow inside the case?
6. Did you make sure that all Push-Pins were fitting and were hooked-in correct?

In some cases users have similar problems but in most cases it can be solved. Please answer to the mentioned questions.

Greetings,

I think all is OK. With Intel BOX there isn't a problem.

// The first installation was made by an IT shop. Maybe they installed the cooler in wrong angle, that caused a small deformation of Ninja holder by MB mosfets so now there isn't a pressure between CPU IHS and Ninja base. //

Well unless you are not interested in solving this problem, I would go on and try to solve it

If it is about the clips, we can send you a new Socket 775 clips kit if. Send me your full address via PM, that should be safe and fast.

Thanks for your answers

I'm from Czech Republic and I'm not sure where the problem is. I'm searching for somebody with AMD AM2 CPU now, if it will work fine I sell it to somebody for AM2 CPU or else I try sales return.

I have bigtower case with one front and one back 12cm fan and 7900GS VGA, so the ambient isn't very hot.

This high temperature problem with the new Ninjas, on socket 775, seems to be very common all over the world. It is definitely a fitting problem with the retention bracket assembly, causing one or more push-pins to loosen, which then causes uneven pressure of the heatsink to the CPU.

The first post in this thread indicates it. When he pushes down on the heatsink, the temps go down.

Scythe should make some attempt to fix the problem, or at least post a warning about the problem. On a socket 478 board, this problem does not happen.

Hi,

There are usually 2 sides of a story...

Push-Pins are easy to mount and even we sell a huge amount of Ninja PLUS CPU Cooler worldwide and the problem appears sometimes. Most users like the Push-Pins and for those who like metal retentions, backplates and screw around, we have the Universal Retention Kit again on the market. We are working on a new Mounting Mechanism but still it is difficult to develop a completely new mounting which is better than what you have on market already.

The most convinient way is using the Push-Pins because you can not give a normal user screws and tell him to screw everything perfectly to have it not too tight, not too lose etc. We try our best to improve and solve problems in the best way, sometimes endusers can not really see the difference or improvement even there is one.

Yes, just recently I've seen in my friends repair center a MoBo with a capacitor in that a screw was pushed. Funny picture.
Seems a Zalman user used quite a big force to make this.
But the pushpins don't make a good pressure, for what are often blamed by enthusiasts.
The gold middle if hard to achieve.

Errr... what evidence do you have that "most users" like the pushpins? On all the tech forums I visit, it seems they're almost universally loathed. The universal retention kit (at additional expense) is no real solution, as it usually requires the copper spacer between the heatsink and CPU heatspreader to provide enough pressure, which obviously means less efficient heat transfer.

Even your "easy to mount" argument doesn't hold water in practice, as it's usually physically impossible to get all four pushpins to engage properly without taking the mobo out of the case anyway.

I would just like to say that I would gladly buy a Ninja if it had a proper (bolt-through) mounting mechanism. There is no way that I'd use something heavier than the stock Intel heatsink with pushpins. As nick705 said above, you have to take the motherboard out of the case, anyway, and there is no guarantee that it would work properly and have enough pressure (plus, it's often extremely hard to get the last pin to fit properly, MBO out of the case or not). This thread can attest to it. I really don't understand why you can't provide BOTH mounting mechanisms.
