What's the best HSF combo for Durons?

[Dynamix3D]

I wish I could get a Taisol CGK but the heatsink is too large to fit on my motherboard (MSI K7T Pro2-A).

 

[Losty]

how about the taisol cek734?
i have it and it runs great
that doesn't fit, the cek733 is also good but you'll prolly do better with the fop

Dynamix3d,

It wsa probably leftover feelings from that intel thread of yours... No harm done, though.

Losty,

I would say they'd all perform in the same range on thermistor readings, but probably a 5C core temp spread between the FOP38, CGK, PAL, and FOP32(just a guess, haven't had real time to play with my CGK yet).

How's the HSF that comes with the retail Duron 800?
Is it good enough to overclock?

The reason I ask is because of the recent price drop from AMD. I could either get the retail box with provided HSF or get an OEM Duron and separate HSF and *maybe* overclock.

I say *maybe* because I hate a noisy pc more than I need 200 more MHz out of a pc.

Considering I'm still using my old P133, whatever I get will be soooo sweeeet.

Since the Socket A doesn't give an accurate temp reading how should we get around that problem?

I just wanted to comment on the "heatsink feels cool" comment
that I see here, and have seen elsewhere. Ideally, your
heatsink should be the exact same temperature as the core
of the CPU. Although this is an ideal that never happens,
it is an ideal. A cool heatsink is probably not a good thing.

A heatsink at the same temperature as your core would indicate
perfect heat conductivity. This would require a perfect
heat path from the core, through the thermal paste, and to
the metal of the heatsink. A clip that holds the heatsink
tight to the core helps also.

You have to remove the heat primarily through the air. Therefore,
you want your heatsink to have as much surface area as
possible. By increasing the air speed across the heatsink,
you remove the heat more rapidly. You also want the
air going across the heatsink to be cool, but that has more
to do with your case and your room then your heatsink.

So it a nutshell you want:


1) A heatsink made of a material that has good thermal
conductivity.

2) A heatsink that has a tight, solid connection to
the core.

3) A heatsink that has a lot of surface area.
(I think this a weakness of some of the Orbs)

4) Good airflow across the heatsink.

However, at the same time if the surface of the heatsink feels cool it may be a sign that your fan is just doing an excellent job cooling the surface. If this is the case, you can sometimes tell by feeling the air that is flowing out. If the air is warmer than the case air, then that would be a good thing.

Neoplasia,

THere isn't a way around it, except for perhaps the overclockers.com tests recently. they seal off teh socket with some closed cell foam and add another sensor on the backside, one that directly contacts the space beneath the center of the cpu core.

Differences between the backside center core readings and backside core-edge readings(ie KT7 readings) is about 25% higher for center-core backside readings.

Thanks. Too much work for me, I'll just stick to the way it comes I guess.

How about adding this info - what HSF fits on what board?
