Howdy, hoping someone can help. I have a 3.4GHz P4 with HT technology, and the stock Intel HSF. Until recently, everything was running fine, when idle, I was getting temps around 45-48 degrees, and when under load, it would jump to abotu 55 Celsius, 60 at the most, but that happened very rarely. A few weeks ago, I started noticing that my fan was spinning up a lot more than previously, but my temps remained the sameish, maybe a degree or two difference. HOwever, now, it's all gone haywire... When idle, fans running at full speed (and I can hear the fans running at full speed, it's very very loud!), I am idleing at 60 degrees. Running something like firefox, or mIrc, it will jum pup to 65... running a game like GuildWars, it will go up to 75, and start the alarms. Any ideas on what could have happened? No new software has been installed, no new hardware has been installed, no changes at all have been made in the last few months. I looked in task manager, CPU activity is not abnormal at all, so there are no processes running that would cause the CPU to be overused. I'm thinking of buying the Akasa Evo-120, is this any good? In an ideal world, I would like to avoid having to take my whole motherboard out, and removing the original backplate, is this HSF able to do this for me? Hoping for help here, getting really desperate! A.
