A blue tint in the metal can also indicate previous overheating issues.Ĭheck the pads or pins for the same thing. Sometimes you can notice darker regions on the top of the CPU. If you notice any discoloration of any kind, avoid using this CPU. Discolored areasĬheck all around the CPU. This is the most crucial step!Īfter this cleaning method, you will see the copper pad color will be improved and will make far better contact with the contact pins from the socket. If you notice that the pads look tarnished from someone mishandling the processor, employ the eraser cleaning method.Įnsure all the eraser filings have been completely removed before installing the CPU into the motherboard socket for testing. Keep repeating the cleaning process with sections of lint-free cloth and thermal removal fluid until everything is properly clean.Īlways wear gloves when doing this, so you don’t touch the copper contacts in the process.įinally, use a thermal surface purifier to make sure all unwanted residue has been removed. Rubbing alcohol will be ineffective in removing all the thermal paste deposits effectively. If some thermal paste has been accidentally messed on the contact pads, remove it using thermal compound remover. So be meticulous when inspecting the pads so you can spot potential problems that may be causing improper behavior of the CPU. This kind of damage can produce intermittent faults or startup failure. If you can see traces of physical damage, it usually means that the CPU was mishandled at some point and may cause connectivity issues with the pins on the motherboard CPU socket, depending on how bad the damage is. Look at the pads using a magnifying device to compare the individual pads to ensure no damage anywhere. Once your skin’s oils settle on the pads, discoloration or tarnished effect and poor contact will form over time. The pads under the Intel processors are delicate and should never be touched with a bare finger.
