Will the heatsink/fan from my 1.8Ghz p4 celeron sufficiently cool a 3.0Ghz p4? They are both socket 478. It is the heatsink/fan that came with the celeron.

Thanks!

Maybe just sufficient, but you'd better get another one.

do they include a different heatsink/fan for different processor speeds? I looked at a few retailers and it looked like intel only has 1 heatsink/fan for the 478.

Depends. Intel made 3 different heatsinks for socket 478. A Prescott 3.0GHz cpu (commonly referred to as 3.0E) originally came with a "X" style heatsink with copper core and aluminum fins quite similar to those used on Intel's LGA 775 Pentium CPUs. The Celeron D for socket 478 came with a heatsink similar to the Prescott P4, but smaller and in a "spiral" pattern mimicking the LGA 775 CPU coolers. The older Williamette Northwoods only came with one style of heatsink, a plain aluminum heatsink with vertical fins. That's probably what your Celeron 1.8 has. A Prescott P4 at 3.0GHz will not like that old style heatsink. You can get by using the older heatsink, but he CPU will be idling higher than if you used the newer Prescott heatsink. A case with good airflow is key.

This information comes from my own observations with a Celeron 2.0 Northwood and a Celeron D 310, and trying both the old and new Intel heatsink designs to see their affect on temperature. The Celeron D's heatsink was superior to the old Intel design, lowering the idle temps of both chips ~4-5 C over the older Intel design.

In case anyone is interested:
the two styles of heatsinks using the LGA 775 Pentiums/Core 2 Duos. The left came from a Pentium 4 EE 3.73 (and is the same what came with my Pentium D 805), the right one came with a Pentium EE 840.

Type of heatsink used on the LGA 775 Celeron Ds, note the aluminum core (which is solid aluminum, not hollow in the center like the copper core in the Pentium 4 LGA 775 heatsink):

Yeah, you have to be careful. My 2.4C came with the regular (all-aluminum) rectangular HS/F...with a basic fan, while my 3.0C came with a HS/F (also rectangular)with a ~3/8" thick copper base, and aluminum fins(also more-thinner fins) and a temperature controlled fan...which can get quite noisy at full speed. :?

If that in the picture is the old celeron HSF, then absolurely NOT. I must have had a P4 HSF on my 2 GHz celeron because it had much taller fins and had a 80mm fan.

I tried a celeron heatsink to my P4, it would cut the power after 20 seconds. It happened almost all the time. Going back to original p4 heatsink made it work okay. So i guess, celeron heatsink is not able to tolerate the heat produced by p4. Luckily, the processor signalled shutdown due to overhead, but was not worth the risk.
