Most of you will have seen this originally posted in the {SAS} forum about a year ago, but thought it may be of interest ..........

I whipped the Thermalright 120 Extreme out and cleaned the base and as you can see the base doesnt have a bad finish as standard:




However by putting a new craft knife blade across the the base in both directions it was plain to see that it was nowhere near "flat".





So chip and Cooler cleaned and ready to go .........
