Millennium Glaciator II problems

[Kent]

Is anyone else having problems with this heatsink? No matter what I do I can't get my idle temps on my 1800+ below 47C (116F)!!! I have applied ASII several times, each time cleaning the cpu. I'm thinking the small feet on the cpu are not letting the heatsink "sit right". Any ideas?

well, if you apply even pressure (read: all 4 corners) on the heatsink, (while the box is running) do your temps go down? Maybe try putting your case on its right side, with gravity helping out the G2. If your temps dont change, then the problem is with something else.

What's your Mobo and OS? This might help.

Running an Abit KR7A-Raid and ME. Not overclocked yet. Want to get the temps down before I do! I'll try "reseating" the sink and see. If I don't tilt the sink to around a 45 angle when sitting it on the cpu, could the feet get "bunched up" and not let it sit right?

[Kent]

Well, it remounted the sink and still the temp was around 45C-47C idle. I've been building my own systems for 3 years now and I have never had this much trouble with a heatsink. I may order another one and see how it does. I got it because it was getting decent ratings. Maybe I'm not holding my tongue right. :) Any other ideas. Thanks, Kent :)

first off dont take the little black standoffs off.

secnod off have you ever taken that clip that goes through the center out. I did once and my temps skyrocketed. I was not sitting in the same groove when i placed it back it and only applied pressure to basically one side of the chip. I noticed this because i could easily pull on one side of the sink and it would raise up off the chip. Finally got it fixed when back in the same slot.

Try another HS and see if it does the same thing, maybe you need lapping, or myabe you have way to much AS2

Try lapping it.

You sure its making full contact?

Try a bigger size than average of ASII.

Kent, I didn't see you post what the temperature is inside your case when you are getting that CPU temperature. A good temperature T.S. procedure is to run the same setup with the case cover(s) off and see what the difference in CPU temperature is. If you know the speed, core voltage, air temp inside the case and CPU temp, you can calculate the c/w you are getting from your setup.
More than once, I've seen someone who was disappointed with a particular HSFs performance and once we examined his specifics, the HSF was actually delivering the c/w it was supposed to.

I noticed on my roommate's box that ME tends to idle at about 65% CPU utilization. That's pretty dang high for doing absolutely nothing. kernel32.dll is what takes all the CPU cycles, according to ATM (Win98/ME Task manager proggie). I never found a remedy for this - I'd suggest trying WinXP or Win2k if you can. I bet your idle temps will drop.

ya NTFS partitons and OS's seem to manage the cpu cycles and memory comsupmption WAY better

[Kent]

I reapplied ASII, lapped and must have got it right. My idle temps are now 38C. Case/Mobo temp is 28C. Still, 38C seems a little high, but it's better. Thanks, Kent :)

Kent, is that an idle tempersature because it does not sound right. Here's why:

You said you were not overclocking your XP1800. That means you are running it at 11.5x133 (1533 Mhz) and at 1.75V stock core voltage, that is 70W of heat. Now you said your case temp is 28C and at that temp, the HSF holds your CPU at 38C. If you do the math, CPU temp-Air temp=10C and your power is 70W, then the c/w of your setup is 10/70 or .14c/w and the Glaciator II can not deliver that kind of cooling. At full CPU load, under ideal circumstances, the Glaciator II should hold your CPU at 45C for a case temp of 28C. That is based upon Joe C's measured cooling capacity of the Glaciator II of .26c/w here:

One of your specs, core voltage, speed, air temp, or core temp must be wrong, or you were not running your CPU at full load. This is an easy process to calculate, with the right specs.

His core temp measurement is probably not accurate if he is just using the socket thermistor.
