Mac thermal monitoring apps

This cluster comprises macOS menu-bar and standalone apps that monitor CPU/GPU temperatures and fan speeds, with some offering fan-curve control, process-level heat detection, and power tuning. The dated history before the index start is too thin to read a shape from—members predate the index or are undated. Traction is led by HeatMonitor (1 star), while creditwatch and pacer have 0 stars.

ENTRY TIMELINE

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 12 listed below. Unlabelled means nothing has decided yet — not that the answer is small.

  1. 01HeatMonitor1★2 days—hobbymacOS menu bar app that displays CPU and GPU temperatures and shows which processes are heating the Mac.
  2. 02creditwatch0★23 dayslivehobbymacOS menu bar app that tracks prepaid cloud GPU credit balances and burn rates, estimates remaining runway, and alerts before credits run dry.
  3. 03pacer0★9 dayslivehobbyMenu bar utility that sets per-process CPU power modes on Macs to balance performance, efficiency, and fan noise.
  4. 04macfan0★11 days—hobbyMac menu bar app that reads temperature and fan sensors, reports thermal status in plain language, and lets users control fan speeds.
  5. 05ghost-process-sniper0★15 dayslivehobbymacOS menu-bar app that detects runaway, leaking, and duplicated processes and shows CPU and GPU temperatures to help users find what is heating their Mac.
  6. 06openfan0★4 days—hobbyMenu-bar app that monitors CPU and GPU temperatures and controls Mac fan speed with custom curves and presets.
  7. 07ThermalPilot0★16 days—hobbymacOS app for monitoring fan speeds and temperatures and adjusting fan curves with optional CPU and GPU power tuning and rollback.
  8. 08halsoenergy0★19 days—hobbymacOS menu-bar app that monitors and controls a heat pump and solar heating system, logging readings and displaying dashboards and history charts.
  9. 09fandeck0★11 days—hobbyOpen-source Mac desktop app that monitors temperatures, CPU, and memory usage and controls fan speeds via customizable curves on Apple Silicon Macs.
  10. 10HexTherm0★19 days—hand-codedhobbymacOS menu bar app that shows live CPU and GPU temperatures and fan speeds and sends notifications when thermal thresholds are crossed.
  11. 11cool910★6 days—indieMenu bar app that monitors Apple Silicon CPU temperature, fan speed, and clock frequencies, and adjusts fan curves to prevent throttling during heavy AI workloads.

Ranked by traction, highest first, and paged 20 at a time — this is a window on the cluster, never the whole of it. Ties are broken by a stable id so a product cannot appear on two pages or fall between them. Browse every cluster.
