A competitive aluminum heatsink for PIV cooling. — Joe
SUMMARY: A competitive aluminum heatsink for PIV cooling.
which are spaced to allow the 70mm fan to breathe; airflow through the heatsink was quite good.
is not well finished – I could feel the machining marks by dragging my fingernail over the surface; lapping should improve performance somewhat.
I do not have a PIV system (and won’t until things get more reasonable), so I modified the CPU Die Simulator to accept PIV heatsinks for testing. C/W is representative of potential on-die performance, although the interaction of the heatsink with motherboard heatpaths will modify each user’s results somewhat.
|Vantec GSN 7025; 76 watts|
The Vantec unit is competitive with other aluminum PIV units tested to date. I have not yet seen a PIV heatsink that comes close to aggressive Socket A/370 heatsinks.
