How about this for an idea....CPU mounting pressure sensors

[Bleeding-Edge]

After my near death experience with mounting my CPU cooler too tightly, I was thinking....
Wouldn't it be a super idea if mobo manufacturers included sensors that could sense the applied pressure on a CPU from it's cooler as you tightened it up....Perhaps four LED that lit green orange and red as the pressure went up. If this could operate independently from the board's power (as the board would need to be off for CPU mounting....
Imagine, you could get the perfect mounting pressure and make sure the CPU is absolutely mounted flat and straight, with a little tweak here and a little tweak there. You could be sure you have got that crucial bit right straight away, no grey areas, no doubts, no risk.
I am sure this isn't beyond what could be done now, little piezo sensors.....

that would drive up cost and needs power connected to the board.
many cooler like noctua Heatsinks stop at a fixed point and you just bottom out all screws.
others. just screw it down. no need to screw something as tight as possible.

this is the cheaper solution I think, just make sure you have a proper tool that does the right torque and pressure. much cheaper than anything else i imagine... where to find such tools that are precise for each specific screw/motherboard/heatsink, that i am unsure of

There is at least one (likely more) pressure sensor device for 3D printers which helps you level the printer bed. It detects the precise nozzle to bed pressure as you go point to point around the bed. The cost of this device is roughly $15USD for that application. Unsure of the exact size and procedure that would be required to mount the CPU cooler and then remove the device from between CPU/cooler and still retain the ideal pressure. The torque driver seems a more ideal apparatus.

Some heatsinks are 'spring driven' so the pressure does not depend on how tight the screws are.

Even the finest tool, this is useless in a world, that your solution provider, this sales goods with out offering of proper documentation.
Latest smartphones they are bricks of plastic all parts connected with glue.
Wisely made previewsly smartphones, they had screws, their battery was exchangeable, they were better made, easily serviceable.
Torque screwdriver specific settings, they were offered due the repair manual.

Conclusion: If the product manufacturer does not offer in writing, torque screwdriver specific settings, then you have nothing at hand as information.
I am using my 30 years of working experience as torque control, and this is 98% effective.

How? I mean, I've used computers for over 30 years and I've built them and upgraded them for nearly as long and never managed to damage a CPU.
These days its nigh on impossible, as the dies are exposed, unlike in the bad old days when people managed to crack their CPU dies...

You can still overload a spring can't you?

Actually I knocked my old PC the other day when it was running and it cut out. Then it wouldn't boot with two RAM sticks in it. I think I might have dis-lodged the CPU and taken out a bank.....Same issue almost...I will re-set the CPU in it later and see. Hummmmm

Thankfully I haven't damaged the CPU or anything else. The new pc has been running well now for a while.
I will say this again, I was very mindful about how tight to do up the screws on the heat sink. I really didn't screw them up all the way or particularly hard, light finger pressure + a bit.....Still too tight evidently.
Just how tight is too tight? Just how loose is too loose? Tricky, 33 shades of grey here.

Intel's current FC-LGAx CPU packaging requires a slight curvature to the motherboard PCB for the CPU to make full contact with the pins in the socket, so it should be fairly tight.

Hi,
I often use different mounting system for water blocks no springs either
But best is just finger tight snug, not two finger crank

There are considerably easier ways of attaining the same mounting pressure as required , repeatedly and every time, they're called springs and when used correctly with screws or bolts with a machined max install limitation, easily done.

Not many do it right but I don't buy from any company that does it wrong.

My water block has springs, instructions say Then – using your fingers only – screw in all four thumb nuts until you reach the end of the thread.. fool proof

You can still overload a spring can't you?

Look at the design, the spring is only compressed so far.

Since you say you are, take it to 1 with more experience or don't over torque stuff down.

If any board warps, it is too tight, if there is too much play in the hsf, eg moving around, it is too loose.
