Thread: E8400 w-stock HSF - High temps

    Exclamation E8400 w-stock HSF - High temps

    I just got my harware installed and booted the system. I got into BIOS and PC Health says CPU is running at 52C! The case is wide open (Front, 2 sides). Could this be a factor? Room temp is ~75F. I assume CPU load isn't that high while in the BIOS. Right? I loaded Optimized defaults and rebooted. NC.

    E8400:[email protected] / Stock cooler is locked down correctly.

    Could the BIOS temp readings be faulty?

    Even though it is unrelated, I updated the BIOS to F9.
    Going to close up the case and see if effects temps.

    Ignore the PC Health reading for a moment. Download a copy of RealTemp and post a screenshot of the main window. It may be that you have a rare non functioning temp sensor. It's not good to go by the CPU Socket temp any way. It's core temperature that really counts.

    I would re-seat the cooler again. I know you say it's locked down OK, but I'm going to go through it just to be sure. It was a pain in the arse the first time I used an Intel push pin jobbie.
    Before you put the cooler back on, take a razor blade or similar object with a straight edge, and lay it edge down on the CPU diagonally from corner to corner. If the blade rocks back and fourth or if there is a gap between blade edge and centre of the CPU, you have a convex or concave Integrated HeadSink (IHS). There's not much you can do about this other than sand the surface down, but I wouldn't recommend doing it, it's in the realms of extreme. If the CPU is concave, a little more TIM than normal can help to normalise temps a bit.

    Take off the HSF and clean the paste off with a specialist TIM cleaner such as arcticlean or Akasa TIM-Clean. Apply fresh paste to the centre of the CPU. Use onnly a small amount, a round blob about the size of a lentil, or slightly smaller is fine. Make sure all four push-pins are rotated in the oposite direction to the arrows on the top and apply the sink. Fix oposite corners, so do top left & bottom right, then top right & bottom left. If done right, there should be no movement in the heatsink.

    Consider getting an after market cooler if CoreTemp reveals high temps and re-seating doesn't work.

    Thanks for your suggestions Psycho101.

    I did not pull the HSF yet. I booted the ubcd4windows and ran some tests.
    RealTemp 3.0. T=41C. Ran XS Bench and reached T=51C.
    Coretemp 0.99.4 showed T1=41C.
    Speedfan showed T1=40C T2=40C T3=-2C.

    Are these temps more in line with a stock cooler (w/thermal pad)?

    I would call these temperatures perfectly normal.

    If you want to get lower, I suggest buying any cooler from Thermalright specifically the HR-xx series. I got E8400 as well, and it's passively cooled. 44 degrees in idle!

    41C is normal idle with stock HSF

    You can get Arctic Silver 5 and get the temperature down some more.
