Overclocked Q9650 reaches temperatures above 99°C during a burn test.
Hello,
I increased my Q9650's overclock settings to vCore 1.4V, fsb speed 450 and a CPU ratio of 9. After running Intel Burn Test, the CPU reached 99°C yet the test finished without issues. Should I treat this as stable or attempt to lower the temperature? The idle temps are around 60°C.
What speed is that?
1.4v is too high for regular use and temperatures won’t be as bad in games compared to IBT, although on a warm day or heater running on a cold one, you’d want to keep it cooler than that.
If you can maintain CPU OC between 3.8 and 4 stable with less voltage, aim for no more than 1.3v and noticeably reduce heat. If your target is around 4.2GHz?
What CPU cooler are you using? And what’s the airflow in your case?
Edit; Missed the ratio, sorry. So speed of 4050. If you can’t get it stable with less voltage, lower the memory speed a bit.
I gathered information over a 12-hour span, noting an average idle temperature near 40.8°C. I believe my previous reading of 60°C might have been inaccurate due to timing after the IBT session. Is a 99°C during IBT a cause for concern given that my idle temperatures appear normal? Could I achieve faster speeds with reduced voltage to maintain lower temperatures? My cooler is the Cooler Master Hyper 212.
Stress testing for such long durations isn't essential; a short period suffices to evaluate cooling performance. It doesn't accurately reflect everyday computer usage. You should determine the optimal speed and then reduce the voltage as much as possible to enhance cooling and extend the CPU's lifespan. Consider running gaming benchmarks such as Firestrike or Unigine Valley to assess actual temperatures. Intel rates that CPU at 1.3675V.

Aim for values closer to this figure for better results. However, these CPUs are relatively affordable now, making it feasible to release heat through ventilation adjustments.
In essence, finding the right balance is a matter of trial and error. 80* is generally too high. A target around 75* would be suitable for gaming.
Games don’t get as hot as they do with IBT. For games, add about 20 degrees above idle temperatures. Remember, ambient temperature changes can affect performance.
How long did the system stay idle after you ran IBT when it hit 60°C? It cools down quickly—usually within ten seconds. I’m curious if your setup isn’t moving air fast enough or not capturing the coldest air effectively. Heat rises, so positioning the lowest point on the floor could help.
Games won't get as hot as they do in IBT. For games, add about 20 degrees above idle temperatures. Be aware that ambient temperature changes over the year can affect performance.
How long did the system stay idle after you restarted IBT when you noticed 60°C? It cools down quickly—usually within 10 seconds at most. I'm wondering if your setup isn't moving air fast enough or not capturing the coldest air effectively. Heat rises, so having cooler air near the floor would be beneficial.
It took about a minute.
Heat is being trapped in certain areas, its not moving well, so let's take a closer look at what I mentioned and check for possible issues like too much thermal paste or insufficient suction pressure. Don't over-tighten, of course. The Hyper 212 manual will specify the correct number of turns to tighten.
I played Xcom Enemy Unknown and the temperature stayed in the 70s. But if I use the Steam link, the CPU will run at full speed and 100%, which might make the temperature even higher. So maybe I should try running it with a lower voltage of around 1.36?
If it assists in lowering temperature then yes. Adjust memory frequency if it aids in stabilising overclock.
If this was my suggestion, please redo the paste when you have time. If you don’t have any, get a tube of Noctua NH1 and some Isopropyl spray to clean the CPU/sink surface. Look up how much paste to apply.
How is your case airflow? Do you have intake/exhaust fans?
