Hi,

I have an Intel DP35DP and I have some issue regarding the temperature. When playing games the CPU thermal margin drops as low as 15 degrees and the bios alarms sounds. When idle the processor thermal margin is around 40. The problem is that because of the silent technology of the fans or something like that that Intel has implemented the fan's rpms do not exceed 1000 - 1100. It is around 750 rpm when idle.

Question is how can I speed up the fan??

I additionally installed a chassis fan and it reduced the temp fo 5 degrees but with no significant impact.

Something about Intel management engine is mentioned around the internet but it is not compatible with Windows 7 64bit. I managed to install it but only as driver and I see no change.

Also can someone please point out the right spot for placing the CPU thermal probe? In my chasis it is placed between the bars on the upper side of the heatsink.

Can someone present his/her's temps if you own DP35DP?.....and possibly the way they managed to get a big thermal margin on CPU

Any feedback would be great

A concise, practical checklist and explanation to complement and :

The motherboard’s "Processor Thermal Margin" is the headroom between the CPU’s current temperature and its maximum rated temperature (TjMax). A margin around 15°C under heavy load will often trigger BIOS alarms even if the CPU hasn’t yet throttled. Low fan RPMs (750–1,100 rpm) make that margin small; the goal is to increase heat-transfer (better contact and airflow) or increase fan speed.

Quick diagnostic + fixes (in order):

  • Confirm the CPU fan is on the CPU_FAN header (fan behavior and BIOS profiles are usually tied to that header). If it’s on a chassis header the board may treat it with a gentler curve.
  • Inspect heatsink seating and thermal paste: remove the cooler, clean both surfaces, reapply a small, even amount of paste, and re-seat the cooler evenly. Poor contact is one of the most common causes of high temps.
  • Fan-control options: look in BIOS for any fan control, "silent/quiet" modes or manual profiles and set the CPU fan to a fixed/higher curve or full speed for testing. If the fan is 3‑pin (DC) vs 4‑pin (PWM) the control behavior differs—use a true 4‑pin PWM fan if the board supports PWM.
  • Airflow and intake/exhaust balance: add or re-orient case fans for a clear front-to-back flow, tidy cables, and ensure the CPU cooler fan is not fighting hot, recirculating air.
  • Temporary/full-speed test: attach the CPU fan to a Molex adapter or a simple fan controller (for testing only) to force 12V and confirm whether higher RPMs solve the problem; use caution and monitor bearing noise and longevity.

Notes on sensors and the chassis probe:

  • The chassis probe mounted between heatsink fins will read locally influenced values (airflow spikes), not core/junction temps. For accurate CPU thermal headroom rely on BIOS/core sensors or monitoring tools (BIOS/OS sensors reflect package/core temps), and use the probe only for ambient tracking.

If all else fails, a higher-performance aftermarket tower cooler or a higher-static-pressure fan on the stock heatsink typically brings the largest, reliable temperature reductions.

Firstly, have a look in your bios to see if you can turn off the silent technology there.
Secondly, have you thought about an after market heatsink and fan? You are probably using the stock one.
Thirdly, can your case take 1 or more front fan? If so, putting a fan in the fromt that sucks air in will grealty help with the air throughput of your system.
Fourthly, you need to get your temperature probe as close as you possibly can to your CPU. I managed to fit mine by the heatsink retainer that is mounted on the motherboard so that my probe actually touches the side of my CPU!
