Because the fans of the PC spun up so much in turbo mode,
That's interesting, because 286s and 386s normally didn't even have heatsinks. Did they wire the turbo button to the fan of the PSU?
IIRC, heatsinks were showing up on low-frequency 486s and heat sinks with fans on 486s >= 50MHz. I think (but may misremember) that most 486 fans were also always running at the same speed.
(Not contesting your statement, just wondering what weird beast your first PC was ;).)
- Bluecobra 8y agoIt could have been a white box PC. My stepfather’s business computers (in the mid 90s) were from some local mom and pop place that built custom PCs and also supported it if things went wrong. I think they tended to over-engineer things as all the PCs were full size (beige of course) AT towers with noisy fans.
- bitwize 8y agoDating back to the 5150, most PCs had case fans. IIRC sometimes the fans would spin a little faster with Turbo engaged, even if just for effect.

- danieldk 8y agoWindows 95 did not run on a 286, the 286 was very limited in running real mode (8086/88) applications concurrently in protected mode (it did not have the virtual 8086 mode that the 386 had). The minimum requirement of Windows 95 was an 80386, though it was unbearably slow (tried to run it on an 386SX25 or 386DX40). It was usable on a 486 with 8GB of memory.
