Height of retail Celeron 1.1A/1.4 Tualatin heatsink/fan?

[Eug]

My PEP66 is almost 2.5" over the chip. Blocks one of my RAM slots.

What about the retail Intel 1.4 GHz Celeron fan?

Are you using this on a slotT adaptor? The retail heatsink may be too wide for it because most of the ones I've seen are wider than the CPU socket.
