Another successful lapping job

I've not heard of any plumbers tool like that, but then again I'm not familiar with many plumbers tools.

Using sandpaper and a flat surface like a sheet of glass or on a glass tabletop seems to work perfectly. Takes me about 20 minutes. I buy specialized packs of sandpaper for cpu lapping off the bay...costs like 3 or 4 quid or something.
 
Lapped my X3350 today; first time I've done it. Put everything back together and it refuses to boot. Clear CMOS. Still refuses to boot. Opened her up again, air dusted the socket, gave the CPU a good scrub with TIM remover and dusted it, and hey presto, it works again. Guess there must have been some copper dust in the socket or something.

Anyways, no idea if the temps are better, think load might be about 5c cooler, but this CPU is weird anyway.
 
yeah after lapping I usually clean the whole CPU including the contacts with some isopropyl alcohol. There's all sorts of copper and nickel dust on it.
