Just make ur fan not go higher than you like it to go? if you put ur fan to 100% the cpu will just boost higher till it hits 90c again, if you lower it it will hit 90c much sooner, unless it hits ppt first.
90c is not a problem and longevity is pointless since they can run 90c 24/7 for 5 years+...
90c is only a problem because you make it into one, its almost like you think companies cant make products work with 90c...
His 5800x can be a pretty lame one that cant overclock much which will keep it at the ppt it was designed for, where most 5800x can easily go 20-25watt higher.
