Excellent Socket A heatpipe performance – Joe
SUMMARY: An excellent heatpipe solution for Socket A cooling.
A heatpipe is basically a closed tube:
Inside is a liquid that evaporates when heated. As it travels up the tube and condenses back to a liquid, heat is released. The liquid then travels back down to the heatpipe’s base, evaporates again and the cycle repeats.
A look from the side
shows the heatpipe in the center – the aluminum fins radiate off the heatpipe for cooling.
The base of the TTIC Heatpipe is fairly smooth:
When I ran my nail over it, I could not feel or hear any ridges.
The TTIC Heatpipe ships with an Everflow fan #R127015DU – a 70 x 15 mm unit rated at 31.5 cfm @ 3600 rpm, 31 dBA¹. I found it to be tolerably quiet – I measured its noise at 52 dBA with a Radio Shack sound meter 8″ from the fan’s intake, substantially less than a Delta 38 (about 69 dBA). The fan stands off about 5 mm from the fins, which lessens noise. It’s also safe to use a motherboard fan header – 2.8 watts.
The clip engages all three socket lugs – I found it fairly easy to mount – and it does not require a screwdriver.
The TTIC Heatpipe was tested on the CPU Die Simulator which gives results that are unaffected by motherboard influences.

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 TTIC Heatpipe in the top rank of heatsinks tested to date (Heatsink Ranking).
A very effective, relatively quiet heatpipe solution for Socket A cooling. To date, this is the best heatpipe for CPU cooling I’ve tested.
¹Note that manufacturers usually measure fan noise 3 feet from the fan.
