I have an Inspiron 1300 built nearly 4 years ago. I now only use it for visiting/trips and such. Nice price, 1.73 Ghz, 512 Mb ram. Once I got everything I wanted in, it started getting sluggish and when I felt the bottom, very hot. I got this program Dell Inspiron Inspiron/Latitude/Precision fan control
to max fan control which has been an an age old Dell problem with it'* variable speed fan/* control. It helped cool it down, but amazed me at how hot it was actually getting once I could actually see the temps. My memory temps were running a constant 172F and peaked at 202-204 while gaming or hacking with WPE Pro. (Not going to elaborate) Upping memory to 1.25 gig really cooled things off incredibly. Smooth sailing in the range of 100-140ish F . Try the program I linked. It'* free, stable, shows you an incredible amount of info like CPU, GPU, and Memory temps. Processor speeds and load, and gives you total contol pf fan/*. It only works on Inspiron and Lattitudes.
