  • Forum Thread: Northbridge cooler too hot?

    Hi all, I have this dimension 5150 and was curious about its normal operating temperature. Is it normal for the small heatsink to the right of the cpu to be extremely hot.

  • Forum Thread: Noisy XPS 720 H2C - can someone help troubleshoot?

    Hello, We purchased our XPS 720 around Jan. 2008 and it ran very quiet up until about 6 or 8 months ago. It was a gradual thing but it got noisier and noisier. The fans sound like they are running at top speed whenever we run a game or computer scan. If you minimize any game, they seem to slowly go...

  • Forum Reply: Re: INSPIRON 531 HEAT AND NOISE?

    The cooling in the Inspiron 531 is inadequate. I measured the temperature of the Athlon 64 x2 6000+ CPU (using PC Wizard and Speedfan). Core 0 reached 157F, Core 1 hovered around 154F. So, I added four fans to help exhaust the heat: two 40mm fans in the front, a 120mm fan opposite the small vents in...
  • Forum Thread: XPS Desktop Fan Question

    Is the back case fan in the XPS 8500 controlled by the motherboard to only run when needed? I noticed mine not turning last night, but it looked liked it might have been trying to turn.

  • Forum Reply: Re: Optiplex 755 Rear Fan Failure

    Sorry to piggy back on this, I'll create a new thread if required. I have the same issue with an Optiplex 755, but it was brought about by upgrading it. It had XP and a P4 in it, and I wanted to upgrade it to WIn7. So, I installed a spare dual core CPU I had and installed Win7 on it....

  • Forum Reply: Re: Installed new CPU fan in Dimension 3000

    No, it is an Aztec 3 speed fan. As I said, I wish I had read the forum posts a few years ago before I did anything, I would have learned about Dells fan sensitivity issues - would have gladly put an OEM in --- but..... alais..... I thought I knew what I was doing

    My Inspiron 530 has been a very good computer to me so far. However, in the past whenever it has been lightly bumped it shuts off, the power cord couldn't ever be even lightly jiggled. I've had it since 2008 though, and I managed to keep it in a safe place where this rarely happened. However...
