I accidentally crushed the large SMD capacitors C2 and C3 at the top of my SL3XL Pentium 3.
Besides removing and measuring adjacent capacitors for reference, does anyone know what their values are?

Thank you. 😀
I was levering off the old heatsink in the direction of the capacitors which caused them to be crushed. It's very difficult to remove the pressure-fitted spokes that are so common on these Pentium 3 packages. I can sometimes push them out with a tool but this is not always possible.
In the end I found that the easiest solution was to slip in a pair of flush wire cutters to clip the posts to remove the heatsink safely.
I removed capacitor C1 since I was removing C2 and C3 and can confirm that these are 4.7uF.
The one I removed was dead-on 4.7uF while the bulk replacements I ordered were much looser at 4.6uF and 4.9uF. This didn't seem to affect the processor any. I removed l three with hot air aiming away from the CPU to avoid blowing hot air underneath the BGA package. A little bit of solder paste and the repair went smoothly.
The processor works great now. No sense in throwing away perfectly good vintage hardware when it can be repaired. 😀
Good job
