Best airflow case under 1009/8/2023 ![]() ![]() There will be cores that are slightly different temps, that's entirely normal because of differences in the silicon, but at least you'd get to see the swing. That's a clean, consistent 100% load on all cores simultaneously with no varience. If gaming and only using 8 threads, many of those cores would be closer to 4.2GHz doing window/background tasking.įigure out exactly what you are looking at before deciding what needs fixing, because most of the time a single reported temp or speed is wrong, it's just the hottest/fastest core and not representative of the cpu as a whole.įor a good, clear picture of exactly how the individual cores stand, use Prime95 Small fft (not smallest) with AVX tech disabled. When looking at single speed all you'd see on either would be 4.9GHz as that's the primary/master core speed. So at 70 you might see 4.9GHz, but that's only on cores 1-9 with 10-12 at 4.85GHz and 90 you'll see 4.9GHz on 1-3, 4.85GHz on 4-8 and 4.8GHz on 9-12. Above that they start lowering boosts by 50-100MHz on a core by core basis, not all cores the way Intel does it. An intel would see 32-34☌ across all cores, only showing hottest core of 34° which constantly changes depending on when the temp was read and which core hit that temp. You see an idle of 50°, it's really not, it's an idle closer to 30° for 11 cores and a 50☌ hottest core. That = a major load =much higher idle temp, but that temp is on 1 core, not the whole cpu. Ryzen at idle puts all cores except 1 to inactive, asleep, so the entire load of service/processes gets dumped on just 1 core. When applying multiple services/processes, they get split up amongst all the cores, so each core gets a very minor load. An intel at idle lowers voltage/speed on all cores, but all cores remain active. ![]() Throw out any preconceived notions of temps, especially at idle. Push/pull is basically of only any usefullness to a full custom loop using higher fpi and thicker rads with far more resistance to airflow. So push/pull adds complexity and noise for all of 2-3☌ difference. To try to get around this, one should over-provision on size.Īlso, something I picked up on recently, is the idea to remove the rear exhaust fan, as it's just stealing a fresh source of cooler air that could feed through the top rad instead, alongside the front intake.įans have gotten better, aio rads are still the same, pretty minimal resistance because of wide fin spacing and thinner 30mm thickness. Top exhaust, the AIO has to cope with everything below it. With an open air gpu, the components could see an increase of a few Celsius or more. The components behind the rad will see negligible changes in thermals. Yes, the air from the rad going to other components is a little warmer - not a big deal, because again, today's cpus have been really good with how much power they use. ![]() The pro of having the cpu AIO as side/front intake is better cooling efficiency, plus it's a little cheaper to do. Turbo/blower gpu coolers like THIS, can work with top air intake because they expel their waste heat out the rear and not inside the PC. The top intake doesn't work well in scenarios with most open air gpus, because the top intake air ends up 'fighting against' the air the gpu expelled inside the PC. The gap gets even more lopsided when the cpu is under lighter loads. Like, 180w from a cpu at full load pales in comparison to these 350w(and seemingly climbing) gpus. ![]() Modern cpus are really good with power efficiency, whereas gpus look to be doing worse - especially on Nvidia's upper end.Ĭpu heat coming inside the PC hasn't been as big a deal, as they've been using less power overall. ![]()
