>>105583486ddr4 is rated for like up to 95c and my two 3200 mhz cl16 corsair vengeance dimms @ 1.35 volts with a plastic casing and barely any airflow over them only ever reach like 50c (according to the built in temp sensor) when the entire system is pushed to the max for prolonged periods of time so not really at stock/xmp (especially on slow-ish sticks like mine), it might help with stability when doing hardcore autism 1.5v 4000+mhz overclocking tho
