Ok so I have been putting it off for much longer than I should have been, so I decided to change the fluid/hoses on my cooling system. The temps have recently risen from 38-39c idle when I put it together a year ago vs 42-43c idle currently (it is a hot summer in Florida though).
Went to the store, picked up 10' of 3/8" tubing. Then stopped at autozone and got some wet/dry sandpaper to lap my cpu as I had great results last time.
*disclaimer* THe pics were taken with my cameraphone, sorry.
First I removed the waterblock:
Holy crap is it dusty in there! Hard to see in the pic, but you can see where the circular waterblock was making contact with the cpu.
Next the CPU:
Wow it was even dusty inside the socket!
You can see better here where contact was made. Thermal past was zalman zm-stg1, which is what I used again this time.
Cleaned off, still though the heatsink left a 'permanent' mark on there if I wasnt going to lap the cpu.
Now I really messed up here when I started to lap the cpu. Like an idiot I skipped 220 and 400 grit and went straight to 600. Probably made the process 2-3times longer than it should have been.
after using 600grit for a few hours:
you can really see that it was pitted pretty good
Here I went up to 800grit for an hour or two:
...and I'm starting to get there...
and 1000grit:
much better here!
1500...:
and 2000:
My digital camera is broken, wish it wasn't, the finish was like a mirror
