Procurement and Cooling Vendor Implications - Line hint:

Context Before
The shift from liquid + air to 100% liquid systems, combined with higher flow rates and greater cooling capacity, will require changes across the cooling stack.
Evidence
Fans and radiators used in L2A CDUs will become less critical over time.
Context After
That said, L2A is likely to maintain meaningful share during the current upcycle, where deployment speed matters more than full optimization, though the long-term trajectory clearly favors L2L. High-density L2L systems will also require redesigns across much of the TCS.
② Atomic Claim
L2A CDU 使用的 fans 與 radiators，隨時間推進重要性將下降。
