The final results are better than what we have been seeing from similarly sized NengTyi heatsinks, and in fact offers relatively acceptable thermal numbers on the 100W small interface die interface. These are not the kind of heatsinks you would want to be using for any overclocked system, but for an older machine the NengTyi P326 offers decent OEM-level cooling.

It is difficult to say what the retail price of the P326 is these days, but at least users of this heatsink can rest a little easier knowing that the P326 isn't a complete right off. Temperature values are towards the lower end of the spectrum, but for such a small heatsink that is somewhat impressive in an odd way.

Bottom line, while the heatsink can do its job reasonably well for older processors, you'll be better off choosing something newer, and more thermally efficient.
