One of the benefits of AiOs, from what I understood, is they are supposed to not have massive spikes in temperature. With my very old Corsair A70 air cooler, which I never replaced the thermal past on in 6 years, did not spike as much as my CLC 280. Yes I am running a different CPU, with more cores and a higher OC, but it was still my understanding that AiOs weren't supposed to spike as much. My temps can jump 40c in a single second, from 30c to 70c. I maintain temps in the low to mid 60s under a constant load, but the big spikes are my concern.
This is on an 8700K at 4.9Ghz, all cores, on 1.32 Volts. (Final tuning of OC is not finished yet)

Look at my join date and ownership history before you try telling me I'm not a real fan of EVGA. I even bought the damn hat.
