Question 1

What is the W/m.k rating?

Accepted Answer

While NT-H1 had a thermal conductivity of 8.9 W/m.K and a density of 2.4 g/cm³, NT-H2 has a density of 2.81g/cm³, although the thermal conductivity is unspecified (should be around 9 W/m.K. Do note that Noctua is still sending NT-H1 with their coolers, which is why you can get the NT-H2 only through the stores.  ~posted from the first result in my google search... (throws hand in the air)...  Noctua doesn't list the W/m.K officially.  From use I would agree with this information.

Question 2

hello, what thermal conductivity does this pasta have? ...

Accepted Answer

I don't recall exactly. About 3 years ago I tested several using a 5960X overclocked to the max and it was producing about 260 Watt running Prime 95. The NT-H2, Thermal Grizzly Kryonaut, Thermalright TF8 and Arctic MX-4 performed the same +- 1 to 2 degrees which is margin of error. I did not like the Kryonaut Because it was messy when you dismount the cooler you better lift it straight up and hold for a few seconds otherwise it pulls strings of it all over the MB. Arctic Silver 5 definitely did not work as well nor did any of the standard white compounds.

Question 3

Why can't I buy nt-h2 in Washington's State?

Accepted Answer

Washington State has a law that any disposable wipes have to be labeled, "Do Not Flush" on the package. If a product has disposable wipes without the required statement, they will be barred from sale in the state of Washington. The NT-H2 10g package comes with disposable wipes that are not labeled with the proper label; they cannot be sold in WA. I think it's ridiculous, but I wanted to give you an answer.

Question 4

isn't Thermalright at 14w/m.k a L0T better ?? that is IF U CAN AFFORD IT.

Accepted Answer

The only product that will perform better in any meaningful way is a liquid metal.  Otherwise, all decent compounds perform within a half a degree.  Instead, you should be much more concerned with “run out” which is a measurement of longevity. A good compound will last several years without showing a reduction in performance. Noctua makes excellent compounds.
