An excellent balance between noise and performance – Joe
SUMMARY: An excellent balance between noise and performance.
The kind folks at Vantec were nice enough to send a sample of their latest heatsink, the Vantec Aeroflow (model # VP4-C7040). This is a sawed aluminum heatsink with a copper plug insert which sits on the CPU core. Airflow through the heatsink is quite good – air exits from all four sides.
The copper plug is 25mm in diameter, about 18mm long and is well finished:
When I ran my nail over it, I could not feel or hear any ridges. It sits in a “well” about 20mm deep, surrounded by the aluminum finned base. Only the copper plug contacts the CPU core:
The fan has no identifying label (99% sure a YS Tech PD1270155B-2F) – a 70 x 25mm TMD unit (small fan hub – drive magnets in fan perimeter) – rated at 36 cfm @ 5600 rpm, 38 dBA. I found it to be tolerably quiet – I measured its noise at 63 dBA with a Radio Shack sound meter 8″ from the fan’s intake, substantially less than a Delta 38 (about 69 dBA). It’s also safe to use a motherboard fan header – 3.8 watts.
The manufacturer’s noise rating is 38 dBA, typically measured 3 feet from the fan.
The clip was a easy to mount, but very stiff – push down on one side, engage the retention base, then push down on the other and it’s on – simple and secure, as long as you have strong fingers.
In summary, an aluminum fin / copper plug heatsink with a very secure, stiff, easy to use clip.
I tested the Vantec on an Acorp 4S845A motherboard with a modified P4 1500 to read CPU case temps.
