Both chips at similar wattage/heat level will have very similar temperatures so should perform similarly under these coolers. Granted the 8350 can use higher voltage and may well be hotter (higher wattage) when overvolted but I don't see how these results are not comparable.
I'm only saying that air coolers perform at same level as CLC.. that SA SB-E Extreme (with TY-143 - 2500rpm fans) has better cooling ability than H100 with stock fans at similar noise level.. and that applies to many of the top coolers with high output fans.
Silverstone HE01in stock form is only 2c warmer than SA SB-E Extreme.. and Phanteks PH-TC14PE, Noctua NH-D14, etc give similar performance with high output fans.
You are right about more 8350's making 5.0Ghz on CLC than air. But there are not many out there running high output fans either, and top CLC's do have a couple degrees better cooling.
If the goal is 5 ghz, the stock TDP has little meaning. The Vishera will stray a long ways from that value in this situation.
The thermal maximum is much closer to ambient temperatures with the AMD , Intel chips that have a larger delta to work with between ambient temp and maximum temp.
That changes the dynamics greatly as does the increased voltage you already mentioned.
In some situations , like a mild overclock on an extended test, I could see big air coolers having an advantage due to the fact that liquid coolant could become saturated with heat to a point where it was above ambients.
I have a 2600k that will run 5 ghz on 1.43 volts. I can stress test it at those values using an H-60 in pull configuration and it never gets out of the 70's C
If that was the only cooling challenge i was ever faced with , my views would be quite different than they currently are.
Most cooler reviews are done using Intel rigs, which is a great help when choosing a solution for an intel rig.
I wish they would also compare solutions more often on AMD rigs.
I appreciate your ability to question a viewpoint that may challenge your own in a respectful manner,
Thank you Doyll
