|I installed SpeedFan and definitely seemed to be running hot. Also tried putting a small table fan blowing directly on it. Seemed good for a while but then shut down twice yesterday. We're in the middle of a heat wave out here in O.C. (100 yesterday) and I don't have a/c going so it's probably 80 or so in my place. Today I went to MicroCenter and got an Antec HGC 520 pwer supply -- it was a returned item on sale for $70. It's a higher end gaming power supply unit (I don't use my system for gaming though and I have the stock video card).|
Install was pretty straight forward. The fan on it is on the bottom so it seems like you're installed the unit upside down, but it fit in just fine. All of the cables from it are shielded and it has many more than the stock unit. Tip for installing: I unscrewed the stock unit and pulled it out onto the desktop -- the cables are long enough to reach without unplugging any of them. Then with the new unit next to it, I pulled each power cord and plugged in the matching one from the new unit. When I had them all connected, then I put the new unit inside the box.
In SpeedFan I have all three fans (CPU fan, rear case fan and the new PSU fan) set to "Software" under the advanced config settings. So far it's running silently and the temps seem to be staying in the green zone.
While I had the case open I also thoroughly cleaned the CPU fan and found significant dust inside it -- I've used compressed air to clean the unit regularly but when I went at it with cotton swabs I pulled a fair bit out.
Now it's a matter of seeing what happens over the next few days. I'll post back my results in case this helps anyone else with the same issue.
