I didn't use water. Use Mineral Oil, it's cheap and non-conductive. Worked great for me.

And if you feel you must protect the underside, use the plastic doohickey that came with your CPU, or maybe the one that covered the CPU socket on your MB.

It's worth it, trust me!

Nice, now lap that Q6600, most Q6600 are not even close to flat at all. I will probably lap this E7200 soon as I swear I can see a lump in the middle of the IHS, shows how flat it is but for some reason Iam a little scared to do it, while with the E4500 I coulden't wait to lap it..

That's why I asked if it was flat or not. I've just never had a zalman heatsink that wasn't flat at least a 9500 or 9700 zalman tends to make sure their contact surfaces are flat and pretty .

Don't force it down. Let the weight of the hs do the work. Try to squeeze you finger between the heatpipes. That's what I did with my Tuniq when I lapped it.

yeah you can pay close to 70 bucks for a TRUE and get a poorly machined base...

You don't need to use water when sanding a cpu if you are using wet/dry sandpaper. A large heatsink is about 10 times more difficult to sand than the cpu.

You don't have to cover the contacts on the back, you can just wipe them off with alcohol when you are done... or if you don't want to take any chances just cover the backside with masking tape.

Just because something has a mirror finish doesn't mean it's flat. You can put a mirror finish on anything not even remotely flat... for example a fun-house mirror! Also going to mirror finish has no advantage for thermal gain either... 800grit is perfectly acceptable and will yield the same results as 2500 grit finish.

I found that lapping the cpu was a WHOLE LOT easier than lapping the hsf. Go ahead and just do it. You'll be fine.

any Zalman 9700 or 9500 owners can tell us that if the base just actually flat or just looks flat ?
