I did some looking, and I determined that my HSF is the
Vantec CCK-6040. According to MBM5, it runs around 6,100 RPM, and cools my CPU to about 131 F, 55 C (motherboard temp reads at 109 F, 43 C, for reference).
I'm thinking that I'll take the guy up on the offer for the kit, but without the peltier and coldblock.
