Temperatures too high with scythe ninja2 cooler

[Ma-Xell]

Hello!
I recently bought a scythe ninja 2 cooler, and my temps are waaay too high.
My temps go above 90 degrees celsius on max load with Prime95 on stock settings with my Q9550.
In this link http://www.overclockersclub.com/reviews/scythe_ninja2/4.htm they test the same cooler with a weaker cpu and get much lower temps.
I have an Antec900 case so airflow shouldn't be a problem.
I have also applied aftermarket thermal paste.

Any help would be appreciated :thanks:

Hi,

2 possible things to explore:
- check the clip system (or whatever) to attach heatsink to motherboard: it must be tight on all parts
- thermal paste: too much is inefficient: not enought contact between proc and base of heatsink !

Try a push pull fan setup. eg 2 fans, one blowing though the cooler the other on the opposite side pulling/sucking though the cooler.

May also want to check that the fan is currently mounted - blowing though the cooler.

-BigDid is exactly correct. Less is more when it comes to thermal paste. Check out this article. http://benchmarkreviews.com/index.php?option=com_content&task=view&id=170&Itemid=1&limit=1&limitstart=4

Don't bother playing with airflow ... unless you are trying to use it passively it's not seated right, if you are trying to cool it passively try not doing that :)

Take it off, clean it off, apply new paste and try again.

Don't bother playing with airflow...

Adding a second "low rpm" fan took 8c off my load temps with my bent fin scythe ninja... But sure ok don't bother...:rolleyes:

I agree with MfA. The temps are so bad that it indicates a problem more severe than airflow, particularly with that case.

That doesn't mean airflow can't be improved. It just means that if the temps are to be believed, then there is something wrong that's more important than airflow.

Yeah, make sure the heat sink is sitting really tight!

I once installed one of those Intel "boxed" coolers and apparently I didn't press all the "pins" down hard enough. Temperatures were far to high!

After I checked the heat sink again and made sure it is sitting really tight (and plane!) problem was gone immediately...

I realize his temps are BAD... Prolly worse than a stock cooler... I have a antec 1200... My 9400 @ 425fsb/3.4ghz loads at 45c-49c depending on the aimb temps.

Its a given he needs to re-seat the block... I'm just saying I've seen many people mount or re-mount the fan backwards - which could also cause the absurd temps...

Additionally both rev 1 and 2 of that cooler work very well with 2 fans...

Download Core temp (http://www.alcpu.com/CoreTemp/) and check the temp differences between the cores. Its the quickest way to tell if the chip is making poor contact with the block...

And as I said

Yea those pin setups are horrible.

Hi!

I remounted the cooler and temps are still pretty high..
I did remove the plastic cover from the cooler and I unlocked the clips pressed as far as they went and locked them.
Although the heatsink isn't very secure if I press it sideways the clips release easily..
(maybe I'll take out the motherboard and try to put in the cooler that way so I can see what is happening with the clips at the bottom)
I also reapplied the paste (AS5) but unfortunately I didnt have any alcohol at home to clean the cpu surface could that be the problem?


Thanks

That's a good idea.
Also after the initial setup run orthos or something to load all the cores for a few hours.
Thermal paste can take a day or two to fully spread out/setup. Sometimes temps get better, sometimes they don't...

It shouldn't be like that! Once the installation pins are engaged properly, the heatsink should sit pretty tight...

If you can pull the pushpins loose easily there is something wrong ... you did remember to turn the pins to the right position for pushing them tight right? (You have to turn them a quarter stroke again from the position you used to get them loose.) If they can really be pulled past the catch by hand they are probably buggered by this point ...

You can buy a retention kit/backplate for the cooler which is tightened with screws instead of pushpins.

[Blue_MiSfit]

I suggest getting the retention plate as well. You'll have to take out your motherboard to install it, but the ease of installation / tight fit is worth it IMO. I have a Scythe Ninja on my Q6600, and it was a PITA to install. The LGA775 cooler mechanism is completely FUBAR in my opinion.... I miss AM2/3 etc...

Its looking like its not seated properly, I built a system 2 months for a freind using the same heatsink and it was VERY cool.

[Ma-Xell]

I took out the mobo and the pushpins simply dont secure properly. not sure what to do at the moment.. I can simply pull out the cooler while scured :(

[MfA]

Well if you sure the pushpins are broke (as I said before, you have to twist them into the right position before pushing them in) then you'll have to get a Scythe Universal Retention kit.
