Please remember that is this is a 1U P4 heatsink being compared against full sized desktop P4 heatsinks. We are only comparing results because we honestly have no other P4 heatsinks to put the Dynatron DC1206BMV up against. In case, keeping that in mind we can see just where 1U heatsinks come with regards to performance in such constrained environments. With such a small fan there is little for the DC1206BMV to do so the results are a little higher than we are used to seeing, but probably pretty good for its class.

Where these results actually come in handy right now is in the realm of the small form factor cube system, like Shuttle's SS50 for example. The ultra-compact computers use either 2U or 1U heatsinks because of the limited room available.

On the 100W test we see a 45 C degree rise above ambient temperature raise which is a lot for a standard desktop P4 cooler, but probably not too bad for a 1U P4 heatsink - we'll have to wait until we have another 1U P4 heatsink to confirm that however.

Given that most of the other heatsinks are too large to fit in a small form factor cube system we can't offer any really good points of comparison at this point, but given the small size of such systems even this heatsink seems like it is under performing compared to a 2U aluminum P4 heatsink for example.... we'll have to wait a few days to find out the answer to that question however.
