I built a new system about a 2 months ago and it is running great except the temperatures showing in the bios seem hot. cpu 67C system 45C
Chaintech 7NIL1 MB
1 stick 512mb pc2700 ddr
Radeon 9200 se video card
300 watt PS
FSB at 166mhz
I am using the heatsink/fan that came in box and have 1 rear case exhaust fan. The room temp. in here is probably around 82 deg. F
Does anyone know if this particular board just reads temps. high? Thank You

MD's Temperature related standard checklist.

Check the following for overheating or perceived overheating:

- Is the heatsink correctly installed ?
--> Verify it is correctly installed.

- Is the heatsink filled with dust and crud ?
--> Clean with compressed air in a can.

- Is the heatsink fan operating ?
--> Replace defective fan with similar or better unit.

- Is the heatsink adequate for that application/CPU ?
--> Verify it meet the requirements for the CPU being used.
--> RETAIL heatsink? May require lapping and better TIM.

- Is thermal interface material used between heatsink and cpu ?
--> Verify it is used, and is applied according to the manufacturers guidelines.
--> Recommended PCM's, thermal pads from "AMD Thermal, Mechanical,and Chassis Cooling Design Guide #23794.PDF.
- Bergquist HF225UT Phase Change
- Chomerics T725 Phase Change
- Honeywell PCM45 Phase Change
- Power Devices Powerfilm Phase Change
- ShinEtsu PCS-TC-11T-13 Phase Change
- Thermagon T-pcm905C Phase Change
--> Recommended thermal interface material aka: grease, gel etc.
- Arctic Ceramique.
- Arctic Alumina.
- Arctic Silver, 3, 5 etc.

- Is the TIM pad cover removed from heatsink before installation, if using supplied TIM pad ?
--> Remove the cover before installation, failure to do so will insulate the cpu from the heatsink.

- Is there adequate airflow or case ventialation ?
--> Verify airflow, add case fans if required.



- Is the Vcore set higher than specified by the manufacturer ?
--> Verify the Vcore is set to the manufacturers specification in the mainboards bios.

- Is the temperature read via the internal temperature diode. Is the tremperature read via the socket thermistor ?
--> Temperatures read at the diode can and will be higher than an external reading.

- Is the temperature sensor properly calibrated ?
--> Several boards have this problem, check manufacturers bios revision history for calibration fix.
--> Does the heatsink feel warm or HOT, if it's warm it could be a miscalibration error.

- Outside temperature high ?
--> If the external temperature is high, then the case fans will be drawing in hot air, especially during summer months. Remeber, when it's Winter in the Northern Hemi-sphere, it's Summer in the Southern Hemi-sphere & vice-versa.

Your room is HOT

28°C ~ 82°F

Your case needs better airflow to move that air out of the case and into the room.
