The Glaciator is an excellent HSF. It is not as good as the MC-462A when the MC-462A is used with the Delta fan it was originally designed for. With all due respect to Joe C., I felt the MC-462A results in his article were unfairly handicapped by the use of the inferior Sanyo Denki fan on it. Here's some raw data, averaged over three runs with three tear downs, cleanings, re-application of AS and re-mounting. Core temps were measured with a Fluke Digital Temp Meter and a Type K thermocouple nudged up against the core, between the HSF baseplate and the CPU substrate. Careful effort went into making sure the thermocouple did not interfere with the mating of the core and baseplate and that the thermocouple did not touch the baseplate, only the core.
For this test, I used my trust 1000/266 AXIA "Y" Tbird

Observations:
Since I had lapped the MC-462A when I first got it, I likewise lapped the Glaciator. The graininess of the copper made it take some work to reach a near-mirror finish similar to the MC-462A.
The clip on the Glaciator was easy to use. Thanks to whoever suggested taking out the PSU.
The reduction in noise over the MC-462s Delta is a great attribute, but I sincerely believe more air velocity would make the Glaciator perform better. The fins and baseplate were constantly warm and the MC-462s pins were constantly cool to the touch. Perhaps if the copper fins were thinner, they would give up the heat more readily, not to menthion, you could fit more of them in the same footprint.
The "head room" difference is very noticeable between the two. Once the 1450 Mhz test was stopped, the MC-462A took the core temp down into the mid-20s C within 30 seconds, whereas the Glaciator was still in the upper 30s. It took 3 more minutes for the Glaciator to drop to the mid-20s.
As you can see from the MBM temps, the Glaciator does indeed register higher on the in-socket thermistor than the MC-462A. I believe there are two reasons for this. First, the MC-462A moves a lot more air around the socket area due to the higher air volume capacity of the Delta fan. Second, since the Glaciator holds more heat in the baseplate than the MC-462A, it radiates more heat back toward the CPU substrate and slows the release of heat from it.
All-in-All, the Millenium Glaciator is an excellent HSF. I have not compared it to the ThermalRight SK-6, or other contenders in it's Price-Point category, because I don't have them, but from other reviews and reports, I would stongly suspect that it is at, or near the top.
For people pushing their Tbirds and Durons up high and I don't mean a 1.33 or 1.4 to 1.54, I mean a 1.0 to 1.5 or a 900 to 1.45, (read >1.85Vcore) I would recommend the MC-462A, with the Delta fan[/b} over it any day. For the rest of you, the Glaciator is a good performer that is built well and should serve your needs.
I know you wanted some simple Glaciator temps, but this was from a post I did several weeks ago and didn't want to re-type it.
