P4 socket 423 or 478?

I'm about to build a new p4 system. I can't decide to buy the socket 423 or the 478 chipset. All I know is that the socket 478 is more expensive. Are there any advantages to getting the socket 478? Tell me the pros and cons please. Any replys will be appreciated.😕
 
Socket 423 has stopped production and will no longer be used. Go with Socket 478. The Northwood 0.13 micron 2.2GHz+ Pentium 4s will all be socket 478.
 
Another reason for the socket 478.

The Intel retail CPU comes with a well designed heatsink and a very quiet fan that is more than adequate for most normal operation. But the CPU still goes up to 50 plus degrees C under full loads. (It is well within the spec temperature range from Intel.) If you overclock and want to get a better HSF, all the newer and higher end design are for socket 478 only.

See this thread.
 
Yikes thermite. I was running my computer at 100% cpu utilization yesterday for about an hour and my temperature never went above 35' (its about 30' at idle). Maybe you're doing something wrong with your retail HSF, because mine is fine.

Jason, I am sorry to burst your bubble. You are reading the wrong sensor or your monitoring program is not setting up right.

The P4 will consume 60 watts or more at full loads. The thermal resistance of the retail heatsink is 0.53 C/W as measured by Dan at Dan's Data. Assume that your CPU is 60W (very optimistic) at full load, and the case is 25 deg C.

CPU core temperature = 25 + 0.53x60 = 55 deg C

It is consistant with temperatures measured by Visionary at VR-Zone. In fact, it is a little bit low.

I measure my CPU at 51 deg C full load. It is a little better than the theoretical predicted temperature. I don't know how you can get 35 deg C. It will take (1)a refrigerated heatsink, or (2) throttle back the CPU at lower speed.

Since your "CPU" temperature only went from 31 to 35 from idle to full load, I suspect that you call your MB temperature the "CPU" temperature. This confusion is easy to happen since popular program such as the Motherboard Monitor 5.1 would not support the AV40 and misidentify the sensors.
 
I have a Igloo 4300 with ASII. Under full load i am at mid to high 40s- the retail heatsink wouldn't do better than this
 
The Intel retail heatsink can keep it at the mid 50's in most cases. It is quite a performance for something you don't have to pay extra for.

The Igloo 4300 is a good unit according to Dan's Data. It best the retail unit by quite a few degrees.
