3D Temperature Monitoring Device
3D Temperature Monitoring Device
We've moved into a new (and perplexing) era of CPUs featuring unusually high power/voltage levels. Manufacturers have introduced thermal resistance through less-than-ideal IHS designs and stacked chips, which now affects everyday users in ways that even serious hobbyists rarely faced before. The online community is flooded with unhelpful advice about poor TIM placement, inadequate mounting, faulty coolers, etc. Recently, I switched to a 5800x3d and will share my experience tuning it.
When dealing with the intense heat you'll encounter on the 5800x3d (and likely in future 7 series models), start using the L3 Cache temperature sensor to pinpoint your thermal issues. If the cache is warm, your cooling setup is likely struggling to maintain core temperatures. This resistance comes from the cache itself, making it harder to keep the processor cool. I may revisit this with more data once I have time to adjust my cooling strategy further.
My upgrade journey: I moved from a 5600x to a 5800x3d expecting tougher cooling needs due to higher TDP (105W vs 65W). I anticipated needing a better cooling solution for the increased heat output. However, the 5800x3d proved even more demanding, pushing temperatures up to 90°C under load. I heard the 7000 series handles this better, but not the 5800x3d either, even with aggressive custom setups.
What adds to the confusion is that poor heat transfer to the radiator appears as low performance. I followed the advice and changed my 240AIO multiple times, upgraded fans to max speed, swapped to a 360 AIO, and still faced similar issues. Each adjustment seemed to lower L3 Cache temperatures slightly, but not enough to resolve the problem. This inconsistency made it hard to trust the data or recommendations I received.
One thing that stood out was how increasing fan speeds on the 240AIO and switching to a 360 AIO caused a small drop in L3 Cache readings. These readings were lower than what I'd expect from standard cooling setups. This encouraged me to give up on quick fixes and explore more reliable solutions, like adjusting voltage settings or running tests with better thermal paste.
I'm cautious about diving deeper into tuning now that it seems the CPU handles high loads well out of the box. It would be helpful for a content creator to run comparative tests using this sensor, especially with other mainstream CPUs from the 7000 series or later.
I notice around 65C load handling R23, the peak performance expected is 80 under a 10GB workload in Linpack Extreme. Something doesn’t add up.
