Those load limits are quite small compared to the load limits of Socket 478 processors. Indeed, they were so small that many users ended up with cracked processors while trying to remove or attach heatsinks to their fragile processor core. This made installing non-standard or non-certified heatsink solutions a risky business. OEM aluminium heatsinks typically provided small thermal tolerances so the improper application or absence of a thermal pad or thermal grease, or operation in high room temperatures, could lead to some Socket A CPUs overheating and crashing.
