Jmke,
If you want, I could do the S478 and S462 in one article.

would be cool

Took a few close up pictures; I am impressed with the quality and overall finish; especially the close to mirror finish; smooth contact areas to the CPU on both S-478 and S-462.

S-478 has "bulb type" temp sensor.

I will just compare them with Arctic Cooling 4 Pro and 2L, since both they are in the test rigs.

Done with all pics...data from current systems (re-ran everything to have all current data). Should be done by tomorrow if not, may just be another day. Hope they deliver as they did in looks.

Problem already..... the thermal control fan in well ventilated case refuses to turn over 1600 rpm; when it gets to speed around 2400, the CPU temp has already jumped to over 68C. With a 70mm fan @1600 rpm, I'm not going anywhere using 2.8C.

Switched to 70x70x25 fan that came with the AXP cooler with no thermal sensor - running now; called the manufacturer and left the guy a message to call back.

that's indeed a bit hot

More news/problem

Design overlook - Heatsink won't sit flush with CPU due to the 4 plugs that hold the P4 retention are protruding on certain boards. Manufacturing tests were done with Intel, MSI and Tyan boards with the plugs flushed (recessed).

Both Asus and Abit are with the plugs protruding (not flushed).

Jmke,

Please check PM. Both reviews done. What a mess.

Rather intesting with the A64 Cooler -

1) Preliminary dimensions show 80mm fan could be installed instead of 70x15 that came with.

2) Can't say why a retention bracket is included.

3) Base finish is nothing to write about; machine marks could be seen and felt.

Frostytech came back and I notice the data listed on the 66IC was reversed.
