1 - always liked toom extra never kabees
2 - I checked one of them today, they're dirty but no physical damage can be noticed, it looks like their original owner(s) never cleaned their PC.
Today it heavily rained, I'm waiting for a sunny day to clean them, then dry them inside my car for an hour under
direct sunlight. One of them is an i7-2600 Sandy Bridge and the other is an i7 4th generation CPU.
I'll test them afterwards and will see
Worst case scenario, I can sell the the CPUs for a total of 200$
