If you’re reading a heatsink article, then you no doubt know that CPU heat is increasing steadily with each new clock increase. The need for greater heat dissipation has advanced to the point that aluminum heatsinks can no longer cut the mustard, as we are now seeing copper coolers and aluminum/copper hybrids. Today we are looking at two products: The AeroCool VP4-C7040 and CA4-C7040 (for Socket 478 and Socket A/370 accordingly). Vantec tries to set their product apart with custom features, namely their AeroFlow Technology and TMD (tip magnetic driving) fans. We shall see how well their design stacks up.
The packages are plastic blister packs to show off their cool design. No doubt they look sleek and sturdy, and the fans look very sharp. The fan wiring is protected from the housing’s metal with some plastic edging.
Opening the package was much simpler than other blister packs, as you can just pop open the top without destroying the entire thing with scissors. Enclosed is a small manual, a syringe of generic thermal compound, and the heatsink/fan combo with standard 3-pin connector. No 4-pin molex power adapter was included. I was particularly impressed that a reusable syringe of compound was included rather than a one-use “ketchup-pack”.
On the inside of the packaging are the fan specs which are listed below.
I had to get a closer look at what the TMD fan and Aeroflow design was all about. So with screwdriver in hand, off came the fan! Unveiled was a cooler that is mostly aluminum (so it is very light) and has plenty of fin area, with a small copper core in the center. The unique four-side aluminum fins are designed with a slope inside the heatsink. You can see that the Pentium 4 and Athlon models differ slightly in layout, due to the different tension mechanisms. Both are pretty much the same design, though.
Despite the minor design difference, you can see the shiny copper center. It is well machined, and no lapping is necessary to achieve an entirely smooth surface. The copper is tightly fitted within the aluminum, and I couldn’t tell if it was soldered together.
