DeltaT v1.0.8
DeltaT keeps an eye on your CPU and GPU thermal paste so you don't have to guess when it's time to repaste.
Most tools just tell you your temperature is high, but high compared to what? A gaming laptop under a heavy load is supposed to run hot. DeltaT doesn't compare you to some generic spec sheet number. Instead it quietly learns your own machine over about a week, how much your CPU and GPU actually heat up above outside air temperature at idle, light, medium, and heavy load, and that becomes your personal baseline. From then on it watches for drift away from that baseline, which is usually the first sign that your paste is drying out.
A few things it actually does well:
It corrects for outside temperature, so a hot summer day at home doesn't get mistaken for degrading paste, and a cold winter morning doesn't get mistaken for a healthy score.
It normalizes for fan speed, so if your fans are spinning faster or slower than usual, it won't misread that as a paste problem. It's trying to isolate paste health specifically, not just react to any temperature change.
It can tell the difference between dust buildup and worn out paste. A fast heat spike with throttling looks like paste degradation. High steady temperatures with fans working overtime at a normal pace looks more like dust or an airflow problem. DeltaT tells you which pattern it's seeing.
If you repaste, it remembers your baseline from before and after, and gives you a straight verdict: improved, unchanged, worse, or inconclusive. If a repaste actually made things worse, like an air bubble or a bad mount, it warns you instead of staying quiet about it.
It also notices if it's been asleep for a long time, over 45 days, and if so it flags your score as unverified until it relearns your machine, since a lot can change in that time.
Beyond paste, it also tracks SSD wear, battery wear, and general board temperature health, though those don't get a paste score since paste isn't relevant there.
Everything lives in a small system tray app that stays out of your way, sips under half a percent of your CPU on average, and keeps a full local history you can browse across 24 hours, 7 days, 30 days, or all time, along with a monthly trend so you can see how things are moving over time.
It's Windows only and needs admin rights to read CPU package temperatures and SSD health, since those sit behind a kernel level sensor driver. The installer handles that part silently.
What's in this release
Cleaner CSV exports, with separate date and time columns in your local time, readable load labels instead of raw codes, outside temperature band, and power source, so it opens nicely in any spreadsheet.
General cleanup of the wording throughout the app for a more natural read.
