Subject: Re: Question about thermal paste NH-U12P SE1366 / Core i7
Dear FlyBock,
first of all many thanks for choosing a Noctua product.
You are right, the FAQ entry is a little bit confusing as it originally comes from
the NH-U12P and thus is not completely right for the NH-U12P SE1366.
We will fix this in the next few days but thanks for you pointing that out.
Regarding the thermal paste it is sufficient to place a drop on the heatspreader of
the CPU,install the NH-U12P SE1366 on it and let pressure do the spreading.
We've conducted numerous tests about this topic on the Core i7 platform and found
this method to produce good results.
If you want to ensure slightly better distribution you can also place a larger drop
in the middle of the heatspreader and four smaller drops 5-6mm away from the corners.
This way you've already spreaded the thermal paste a little bit, but in our tests we
haven't experienced differences large enough to be noticed by the internal thermal
diode.
So however you do it, both methods should give you good results and proper contact
between CPU and NH-U12P SE1366.
