With equal fans, the WBK edges the FOP by a little bit. The WBK is a newer and improved heatsink. The FOP has a smaller footprint (base) and will fit tight spaces. The fins are wider above the base on the FOP. The WBK is a larger heatsink which helps insure a slight performance gain. They both use the same pain-in-the-arse clip!
I would go for the WBK if I had to choose between them. I have an FOP and it works great though. It's on a Duron
[email protected] that never breaks 41c. When mounting the clip, be careful to hold the heatsink square on the core. If it wobbles, you may crunch the core. I used an old plastic toothbrush handle with the end notched to grip the clip with. I hold the heatsink square with one hand and use the toothbrush to push down and latch the clip. Also, the clips come apart easily. The end that has the screwdriver notch in will seperate from the main clip body sometimes when attempting to mount. Because of this, I put the pressure on the main body of the clip when mounting. I had mine seperate a couple of times and have read of others having the same problem. GW has improved the clip, but it is something to be aware of. When you get it and look at the clip, you will see what I'm refering to. It's no big deal, but if it happens while using a screwdriver, you can scratch your mobo! Another reason to use the toothbrush handle!
