The CPU I have turned out to be the tray version, not the box one thus it has no pre installed thermal paste. so the CPU has been running raw, normal usage while temperatures are 100c (18% usage with 100c degrees), should I put thermal paste on it and reattach the Intel stock cooler or call the store for a total replacement? I just saw a thread somewhere saying that running on 100c is enough to end a CPU's lifetime in 27 days so I assume I already killed enough health out of it in a 20 hour usage on 100c?
