OEM Socket A heatsink for “normal” cooling – Joe
SUMMARY: OEM Heatsink, OEM performance.
The fan is an AVC #F6010B12HS – a 60 x 11 mm unit rated at 18.5 cfm @ 4500 rpm. I found it to be tolerably quiet – I measured its noise at 56 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 – rated at 2.3 watts.
The copper plug is well finished:
When I ran my nail over it, I could not feel or hear any ridges. The clip is a good one – engages all three socket lugs – although considering it’s a light-weight heatsink, it borders on overkill. However, I’m sure you could drop a PC off a building with this heatsink and it would not come off. You must use a screwdriver to mount it.
In summary, a aluminum heatsink with a copper plug insert with a very secure clip – low noise.
The AVC #112C83 was first tested on the CPU Die Simulator which gives results that are unaffected by motherboard influences. I then tested it on a Shuttle AK31, modified to read AMD’s on-die diode, as an example of what users might see on their systems.

C/W = Delta / CPU Watts
Interpreting C/W: For every watt (CPUw) that the CPU
consumes, the HSF will limit the CPU’s temperature rise to (C/W x CPUw)
plus the temperature at the HSF’s fan inlet. For example, at an ambient temp of 25 C, a C/W of 0.25 with a CPU radiating 50 watts means that CPU temp will increase 50 x 0.25 = 12.5 C over ambient temp, or 37.5 C. The lower the C/W, the better.
Die Simulator results place the AVC in the lower ranks of heatsinks (Heatsink Ranking).
About what you’d expect – maybe OK for mom, or maybe grandma.
Thanks again to AVC for sending this our way.
