I have an old (2003 or 2004) HP Pavilion a450n desktop that I use for work. Over the past year and a half I've noticed that the fan runs more often and a lot more quickly than it used to. I've done the cleanout with an air can and all that, and it helps but not for long.
About back in May 2007 I downloaded SpeedFan to find out what temperatures were running, and according to my notes, I had, on startup, an ambient temp of 31c, "Remote 1" of 44c, Remote 2 of 29c, and HD0 of 34c. If I had anything "highly" graphic on display (such as the firewords you get when you win Spider solitaire), it wouldn't be but a minute before the fan would kick in...temperatures then would be 31, 60-65, 30, and 34.
Come forward to today. I just did another cleanout-not much dust in there as I'd expected. Booted her up and my initial temp readings were 35, 55, 33, and 30. What's interesting...55 right off the bat! She'd heat up to the 60's again (usually the fan would kick in, but that hasn't happened. She's running quiet.) Now, however, after roughly 10-15 minutes of run time, that Remote 1 temp will actually drop to 47. WTH?
I did a search on this site for information, and wonder...is it my processor/heatsink? The up/down temp readings are kind of puzzling. I'm not really having any other problems other than she does seem to be running a lot slower these days and I do get a bit of lag in response. How can I keep this old girl alive? She's a really good machine otherwise, plenty of oomph for what I need.
Thanks for any advice!
