Hello,
I got a problem with my new Ninja Plus Rev. b

I installed the cooler on my gigabyte EP35 DS3P Motherboard with a intel Q6600 CPU (G0 stepping) @2400 Ghz !not overclocked!

My tempretures in idle after 15 min. fan@ 1200 RPM are( measured with everest + coretemp)

core1- 51°
core2- 52°
core3- 49°
core4- 50°

fluctuating +/- 2°

under Load with 4 Threads of prime

the temps jump within 2-3 minutes to

core1- 85°
core2- 86°
core3- 79°
core4- 81°

...and increasing

then i stop the test because i think thats hot enought

What i did so far :

took the cooler off and tried with more heat-conductive-paste
result was the same! temperatures to high

took the cooler off again uninstalled the motherboard, tried another heat-conductive-paste and applied an ultra thin layer of the paste, controlled the fitting of the f***ing pins (LGA775)

installed everything again ..
but the temperatures are still much to hot (maybe 3° cooler under idle; under load they would still increase till the CPU shut down.


Anyone an idea what i could do ? The temps with the boxed cooler was much lower .

I could provide later some pictures of my installation ,currently i´m at work.

OK I will try the Scythe Universal Retention Kit hope this improves the performance otherwise i have to downgrade to the boxed version and the ninja goes to ebay...

It basically improves safety. It doesn't improve temps significantly in most cases because the stock pushpin installation already delivers a rather good pressure.

Is the heatsink touching mainboard components around the CPU socket? Did you try with less thermal grease? Unfortunately on most Core2 CPUs the heatspreader is uneven which can lead to a really bad thermal transfer between CPU and heatsink socket.

You should also check your airflow.

Ok now i havr installed the kit and the temos are now better under idle but under load they keep increasing above 95°.

No mainboard componets are touched ! there´s like 2/10mm distance tothe transistors.

yes i tried with less thermal grease (the last test was with applied ac cooling mx2 grease thin like a sheet of paper.


If the headspreader wouldnt be even how could the boxed cooler have a better performance??

the airflow could be better when case is closed but the test was with an open case.


And i ound also a part of the problem:
the little cooler an top of the backplates(were no air
arrives is the hottest part of he cooler and theres no way to provide air with the standard cooler so i placed another by hand and could stabilize the temps at 75°
@ load which is a little success for me.

but it´still unaceptable for me

You should contact Shinigami / send a mail to Scythe support - those load temps with open case aren't normal as you already said. And if the stock cooler performs better there's surely something wrong with your Scythe heatsink.

Ok I will try that.

Thank you for your help so far.

Hi,

That's a sticky one, happens very rarely. Sorry for the inconvenience.

1. How is your temperature inside the case?
2. Does the whole Cooler getting warm?
3. Did you try to turn the Ninaj PLUS by 90° or 180°? It might change the contact area.

Worst case:
As you have tested a few different solutions, I can cut these out. The biggest problem is the IHS of the CPU. I experienced that all Intel IHS are taller on the outside. This means if Ninja PLUS has the tolerance of the base going same way (direction of the cooler) you get a hole between both and the contact is really bad. Even best compound would not help. I hope it is not the reason, but we will see based on your answers on above questions.

Thanks for your patience. Are you from Germany? If the worst case scenario is the case, we can do the direct RMA, so please have a bit more patience.

Hallo ich schreibe mal auf Deutsch ich hoffe das ist ok.

1. Das Gehäuse war offen beim testen ( Raumtemperatur ca.23° )

2. Nein nur der kleine Kühler über der CPU wird heiß ! Die Heatpipes werden nur direkt daneben lauwarm. Die Kühlrippen bleiben ganz kalt.

3. UM 90° gedreht ja Temperaturen aber ungefähr gleich. Um 180° bestimmt auch aber dann unbewusst.

Die Oberfläche der CPU Halterung und der CPU scheint plan zu sein aber mit dem Auge ist das schwer 100% zu beurteilen.

Ich habe an dem Kühler allerdings eine Veränderung vorgenommen damit der ins Gehäuse passt. Ich musste die Schraubenblenden abnehmen und ca 0,5 cm der Heatpipes abzwicken (siehe Bild). Meiner Meinung nach sollte dies jedoch keinen wirklichen Einfluss auf die Kühlleistung haben. (dachte ich jedenfalls )

Gruss.

Übrigens die dateigrössen beschränkung ist etwas knausrig.

Ciao Oli

Meister, da haben wir das Problem gefunden. Du hast die Heatpipes modifiziert, was ein absolutes TABU ist, weil du die damit zerstört hast! Nein, leider hast du keine Garantie mehr und den Kühler kannst du nun wohl wegschmeissen. Ich kann dir höchstens einen gebrauchten Kühler verkaufen, aber mehr kann ich für dich leider nicht tun, sorry
