S14E19 - Warning Maths - PC Air Cooling Myths Examined

Wattage and case volume, how do these things impact number of fans and air cooling? Do large air coolers help? Is orientation an issue. I’ll wager, some of these things within this video have never been thought of. © 2024 Del Delbridge

i tought the i7 7700k was notorious for getting hot.. but they said that for my i7 6700k aswell.. undervolted/+ slightly overclocked it runs well for me. i'm curious about your findings..

@@RaphaelSwinkels - I can't remember which processor is in this video. I do have (the original one that came in this Corsair case) is 7700 but not a K - not unlocked. The CPU sitting in that same case is unlocked - it's a 12700K. And it's finally at max ratios but undervolted pretty well. I don't have the floating point extended instructions on
If I use XTU on the 12th gen at auto set - it gets hot when running CB 24 and thermal throttles. In real life, I don't see high temperatures. So I have it running on air, I used recommended settings, saved, then turned off the floating point instruction set. I don't really need them. Took notes. Reset to the defaults and slowly walked the voltage down and ratios up over a couple of weeks. I don't keep the room cold it sits in. Normally 77°F. Where it is set today, the ratios are 50, 39. It is undervolted pretty aggressively - at least more than I would think I would feel comfortable. AVX512 instructions, as I meantioned, are off. The power limits are up and using Cinebench 24 It's stable and back to 1150 - 1160 +/- maybe a 91, 92ish° on core 5 I think it is. It's always a hot spot. Another core gets warm too, can't remember which one.
Air gets up benchmarking but it's not too loud rendering a video. The software will not use full GPU, CPU or memory. CPU will hit 57°C ISH. GPU doesn't heat up because there is no RT or Shader cores. Haven and Furmark will warm it up, but even it OCed, fans are not too noisy.
