Ryzen 7 3700x very very high temps
I am working on a build using a Ryzen 7 3700x and an asus b450 mini-itx board but currently it is outside the case with a fan blowing on it for testing (to eliminate airflow issues). I have tried two different coolers, the Cryorig C7 Cu G and the Noctua NH-L9x65mm using a bb sized drop of cryo grizzly cryonaut thermal compound (and yes I spread it out with the spatula). I am getting great contact on the CPU, especially with the noctua cooler and the fan is set to max at all times however I am getting horrendously bad temps (~50c idle ~90c during cinebench r20... even hitting 95c with intelburn test which sometimes causes it to throttle and other times it thermal shutdowns)... same with both coolers. What is going on here? I am at my wit's end, I am starting to wonder if this CPU has an air gap between the die and the heatspreader, but I feel like that is an extremely rare occurrence... I tried both the ryzen balanced power plan and the regular windows power plan, no change. I tried setting the cpu voltage offset to - .100 but that just made it more unstable for about 1c of difference. Everything is bone stock no overclock or anything, literally optimized defaults except for the fan being set to max.
***? Any help would be great.
Temps were measured using HWinfo and Aida64 (which report about 3-5c less than ryzen master but the same compared to eachother)
