I've been wanting to strip my venice for quite a while...but with my previous xp-120, the mounting would be a challenge.(Clip-ons aren't exactly favourable for this)
So off with my xp-120 n in comes the BigTyphoon, which is screw mounted. Hell, i should've bought Bigtyphoon from the start. Definitely better den the overated xp-120 imo. I got cooler temps n higher overclockability with it. Problem is, the base finishing is horrible. Thats where lapping comes in. Since this is my 1st lap job, i wasn't sure how much to buy so i bought 1 of each. 220, 400, 600, 800 n 1000grit. My plan is not to make it uber shiny but flat n scratchless.
Lets see the base before lapping.

After lapping.

Notice the red circle i've marked. This spot remains untouched by my sandpapers. Due to shortage of 220grit i can't get it all flat.:unhappy: This shows how 'unflat' the base is.
Next, some surgery on my venice. I 1st tried using a penknife but the blade is too thick. Best is razorblades i guess.

Here's (http://www.xtremesystems.org/forums/showpost.php?p=1028186&postcount=30) a good indication of how deep u should cut in.
When u cut, dun use the slicing motion. Instead, push your blade in n do the rocking motion slowly.
After some sweating, off comes the IHS.

Notice the red circle again. Seems like i've cut in too deep n chipped 1 of the small thingys!!:shock2: Will this be the end of my venice??
Well when i put it back in to test, long beep. Crap. I've done it. I've killed my 1st chip. Never one to give up easily, i took it out to inspect 1 more time. After much squinting, i spotted a bent pin! I bent it back n it started up without problems thank God.
Next up adding a thermal probe to monitor temps.

Finally, BigTyphoon is screwed down with a couple of wingnuts bought separately.

However after all this, results aren't very rewarding. Temp readings from onboard seemed the same with the IHS off. With the thermal probe, its reading temps abt 1.5degrees higher at default settings. But at 1.65v 2.7ghz, its reading 3 degrees lower den wats on my mbm5.
Reading from mbm5 on load=40
Reading from Aerogate II=37
So which will i trust now? I've made sure the thermal probe is touching the core. Not calibrated perhaps?
Anyway this has been fun and i hope u can learn something from my experience.
