Orbs are not good cooling solutions for CPUs. The Blue Orb aka BLORB or baby orb is OK for smaller chipsets/graphics cards but stay away from the Gold/Silver/Platinum/Seafoam green orbs for CPUs.
The Volcano II is a decent HSF. So is the FOP32 or any of the other highly recommended ones. Thermal pads are junk.
1. Scrape off as much thermal pad as you can w/your fingernail. NOT a screwdriver! You don't want to scratch or nick the bottom of the HS.
2. Any remaining pink goo comes off easily w/some WD40/fingernail polish remover applied on a paper towel.
3. After all the pink goo is off, was HSF under hot soapy water (NOT dishwasher ) and dry thoroughly.
4. Before installation, wipe bottom of HS with papertowel wet w/rubbing alcohol
5. Apply a thin (almost, but not quite see-thru) layer of AS/ASII to the CPU core (the little metal square part w/the writing on it)
6. Install HSF. You might want to read
AMDs Heatsink Installation Guide first, I've you've never done this before.
Good luck.
