The CPU was positioned at the front of the board, drawing fresh air from the intake there. Usually there weren’t any exhaust fans—just the main intake at the front. The design was flipped, so a dual slot card would protrude and wouldn’t fit in a 16 at the top. The main problem seemed to be the two-core chips. BTX was built for handling hot P4 and Pentium D chips, but with core 2 it became unnecessary.
In reality, some boards feature DIMM slots aligned with expansion ports. For instance, the EVGA Z390 DARK and my Asus M2N32 SLI Deluxe are examples. I believe the BTX benefits weren't really aimed at consumers, as it demanded a distinct case design. This would have led to separate case configurations for ATX or BTX systems.
Interesting: https://en.wikipedia.org/wiki/BTX_(form_factor) Here we are still relying on ATX after fifteen years. It seems the original design aimed to handle the intense heat from the P4 chips that were later swapped out for more efficient cores, eliminating the need for such cooling. Yet it's odd how the top TDP ratings of those old P4 "engines" hover around 115W—far less than what we see today. Right now I'm pushing a CPU up to 280W, and my case handles it just fine. I can even run my 9900K at 130W in a 4.7L unit with a GPU. This suggests people realized airflow matters and adding a few more budget fans was probably smarter than overhauling the whole setup. Today we're at a point where most mid-range PCs stay cool enough without special fixes, and for those craving top-tier cooling it's now part of the experience. It's wild that we're still using a standard from two decades ago. But hey, if it keeps working, that's all that matters.
