Socket A Mechanical Load Limits
AMD recommends that the mass of a Socket A CPU cooler to not exceed 300 grams (10.6 ounces). Heavier coolers may result in damage to the die when the system is not properly handled.
All socket A processors (Athlon, Sempron, Duron and Geode NX) have the following mechanical maximum load limits which should not be exceeded during heatsink assembly, shipping conditions, or standard use. Load above those limits may crack the processor die and make it unusable.
| Location | Dynamic | Static |
|---|---|---|
| Die Surface | 445 N(100 lbf) | 133 N(30 lbf) |
| Die Edge | 44 N(10 lbf) | 44 N(10 lbf) |
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 for their fragile processors. This made installing non-standard or non-certified heatsink solutions a risky business.

Famous quotes containing the words mechanical, load and/or limits:
“No sociologist ... should think himself too good, even in his old age, to make tens of thousands of quite trivial computations in his head and perhaps for months at a time. One cannot with impunity try to transfer this task entirely to mechanical assistants if one wishes to figure something, even though the final result is often small indeed.”
—Max Weber (1864–1920)
“Men so noble,
However faulty, yet should find respect
For what they have been. ‘Tis a cruelty
To load a falling man.”
—William Shakespeare (1564–1616)
“You must confine yourself within the modest limits of order.”
—William Shakespeare (1564–1616)
