Did you know CPUs use to come without an IHS? Did you know that CPU sockets use to be slots and giant HSF were default mounted to the side? Did you know old sockets had no lever mechanism? You pushed the CPU into the holes and pulled out with a rake tool. Did you know the first socketable CPUs didn’t require a fan at all and the heatsink slide onto a ceramic top using integrated ‘rails’. I built desktops using all of the above going back to the 486SX days.
Things change. Its called “progress”. Water cooling is almost standard on 200W peak CPUs. And by no means will the CPU socket mechanisms be the same in ten years as they are today. You might be young. It would be wise to get use to change.
Did you not read the first part of my reply to someone else?
I mentioned that I have built PC's back when there were no IHS's. Funny you mention a time with 'no levers', because well... we've had levers all the way back in your "486SX days". Of course, both manufacturers no longer use PGA, they both use LGA, which would be a signficant redesign to the socket for your proposed fused custom block idea.
I find it a but funny that you call going
back to not using IHS's progress. IHS's were never really 'progress', however they were insurance for the CPU manufacturers. They make it easier for everyone involved down stream of the manufacturing process. No more cracked dies from improper mounting, resulting in what I suspect would have been tens or hundreds of thousands of warranty claims, most of which weren't valid because warranty isn't covered by cracking the die during the mounting process.
We will not return to CPU's without IHS's because of this. Bare die mounting too large of a headache for everyone involved in the PC building process, that includes DIY PC builders, OEM's and the CPU manufacturers themselves.
The DIY
Custom Water Loop PC building is so niche I'm actually quite willing to bet you'd never see a CPU manufacturer do it, unless the product is marked up to some extraordinary amount (Get the i9 15950ks, now with direct die fused water block and custom mounting kit for a low price of $3,000!).
