EP02 — Silencing $42 Corporate E-Waste to Hear Far Cry

The OptiPlex 990 gets a cooler that fits Dell's own mount, de-Delled fan plugs, and drops from 74 °C to 45 °C.

A heat wave, Far Cry, and a fan loud enough that if anything really were crying in the distance, I would never know. It is still the $42 OptiPlex 990 from episode one — and I was not going to put more effort into it without getting something back.

Ashamed of running cheap corporate e-waste? At least I own it. With anything modern you do not buy to own anymore — you rent, and you can be kicked off any platform at any moment. This box answers to nobody, and now it does so quietly: the CPU dropped from seventy-four degrees to forty-five. Not that I was worried.

The mod

  • Dell’s proprietary fan plugs exist so you buy Dell fans. The pins underneath are ordinary — only the plastic shell is scary, and pliers fix that.
  • A new CPU cooler that screws straight into Dell’s original mount, no new backplate needed — easier than a stock cooler swap on a retail 1155 board.
  • One wire shuffled back on the plug, because they kept the connector but rearranged the wiring anyway.
  • An extra fan for the GPU in a spot with no official mount. Its RGB goes unacknowledged; the keyboard already glows in vain, and that is enough vanity for one desk.
