One thing I soon noticed after switching to a FCPGA type P3 was the small size of the heatsinks available for these processors. They are half the size of the slot type heatsinks and just don't work as effciently.
I installed an Alpha PAL35t a couple weeks ago which works much better than the Thermaltake GORB did in my system. It just didn't get the temp down as much as I wanted.

Anyway, the Alpha PEP66 caught my attention since it is twice the size of the PAL35t heatsink. The only problem is it's made to use with slotkets only. Then, I came across a thread at HardForums where a guy that goes by "shrink" made a PEP66 fit in his BX133 mobo.

Thanks shrink!!
I followed his directions and it was easy
So here's how to do it with pictures.
Here's the PEP66 on the left and the PAL35t on the right. Notice the size difference...
The key to making the PEP66 fit is to remove the ugly green BX chip heatsink and replace it with a thinner heatsink.
This is a good thing since ABIT doesn't use any type of paste or thermal pad under the BX heatsink. It's just sitting on the bare chip!!!! This also shows where I attached the Thermal probe on my processor with Kapton tape.
Here's the new thinner heatsink. I put this one on with Arctic Silver paste and a drop of super glue in each corner to hold it down.
This shows the PEP66 fastened to the processor. Note that I have the fan shroud attached opposite of Alpha's instructions so it faces the DIMM slots.
Does it work better??? Around 2-3 degrees cooler than with the PAL35t using a Delta 60mm fan on both
It's easy, all you need is a thinner heatsink for the BX chip and there is room to spare in the ABIT BX133.
