AVC Z7U7408001 Heatpipe P4 Heatsink Review

Abstract: The AVC Z7U7408001 is an amazingly powerful heatsink, the name isn't very consumer friendly, so bear with me as I get used to typing out a 10-digit product number...

Home > Reviews > Page: Final Heatsink Temperature Comparisons

You'll note that I've dropped out the actual test figures, and so FrostyTech is only showing the final rise above ambient temperature results in heatsink reviews from now on. With the number of heatsinks we have reviewed, the list was simply getting too long; and given the choice of keeping one long list of comparative heatsink results, or two shorter ones, I chose the former.

Information not expressly stated anymore concerns the pre-applied thermal pad (we remove this for testing any way), the number of fans, general fan noise and clip force observations, and ambient temperature.

As always, Frosty's Synthetic Temperature Test results for the Socket 478 Intel Pentium 4 platform are grouped according to the results of the 100W test die.

The radically designed AVC Z7U7408001 weighs in with high-performance results in our list of reference heatsinks. In the comparison above, which illustrates final rise above ambient temperatures, the AVC Z7U7408001 heatsink manages a respectable 25.8 degrees Celsius - just 5 degrees warmer that the current top rated cooler/fan combo we have tested.

With figures like this, I think it's easy to agree that AVC are more than just another OEM company producing heatsinks under another brand name. The AVC Z7U7408001 isn't the quietest heatsink in the Pentium 4 inventory, but it handles the task admirably for something of its size, and weight. Virtually all the other heatsinks which have managed to produce thermal results under 30 degrees are constructed primarily from copper. That makes them heavy; 600 grams, 700 grams - a big load by any estimation. This heatsink is much lighter than any heatsink above it, except perhaps the Thermal Integration Ti-RV104N.

Bottom line, with its twin heatpipes, and twin sets of cooling fins, the AVC Z7U7408001 Pentium 4 heatsink is a pretty good high performance cooler, and an excellent one considering its mass. Although it creates upwards of 64 dBA noise, it should easily find a home in high end systems that need Prescott FMB1.5 cooling capability.
