Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I know a little about overclock but can I do the reverse?
Summer is comming up and I dont want to overheat my CPU
since I burnt one last summer having the computer up all day.
I dont need all the performance to just surf sites, chat and watch movie
I am wondering if I can limit the P4 2.8e to 2.0GHz.
the only way to do that is in the bios, simply lower the front side bus or the memory bus or the cpu bus, which ever its called in your bios.
if this is a store bought pc then chances are you wont have any settings like that and your screwed.
frankly if you burnt on up just by having it on then you NEED a better heatsink and fan.
id invest 30 bucks in a nice copper heatsink and fan and some good arctic silver 5 thermal paste. and have someone put it on who knows how to do it properly , if you dont.
90% of the time your not gunna burn them up from heat simply becuase all cpu's and motherboards have built in thermal protection that when it gets so hot your system shuts down.
that depends on what cpu it is.
if its a Pentium 4 then NEVER go above 60c
70c will kill the chip
if its amd it depends on what,, if its an amd XP then 35-45 should be normal
if its an amd 64 then about the same 35-45 deg Celcius should be normal.
basically most chips will opperate at around 35-45 just sitting in windows, when your gaming or running heavy applications temps can go to 45-55, 60
if its an amd64 or Athlon XP and your hitting 50 Celcius then you got something wrong, and thats bad for those amd chips.
try as much as you can to keep the temps in the 35-45 range for AMD
35-55 for Intel Pentium 4
Heatsink paste like Arctic Silver becomes hard over time even though the manufacture say it will not get hard, so every 3 to 4 weeks take off the paste and apply new paste. If you do not want to do that, use tape. Tape is better, less messy than heatsink paste, and less errors during the apply stage. Usually with heatsink paste people put too much or do not know how much to add.
I suggest Zalman's CNPS7700-Cu and at least two fans. One in the front blowing in and the other blowing out. Power supply fan does not count as a fan.
never ever tell anyone who is concerned with heat to use tape. EVER thats just rediculous that you would tell him to do that.
with all do respect if you knew what you were talking about you wouldnt be telling him that.
and if you knew also Paste ONLY gets hard on the parts where air is constantly getting to the paste, the paste thats on direct contact with the HSF and the cpu die does NOT get hard , this is a fact.
It also is not needed to replace the paste every 3-4 weeks, thats just rediculous that you said that.
also a fact is that tape is the WORST conductor of heat. not to mention the fact that you go trying to pull the HSF off and you are gunna take about an 80% chance of yanking the cpu right out along with the hsf and damaging the cpu because the locking arm is still locked.
ive had many times where i got a system for myself or for repair, that had tape on it and very quickly learned that tape, when its cold, is stuck to the cpu with such force that you have to pull on the hsf so hard.... well the cpu gets yanked right out also and you CAN damage the pins on the cpu.
you have to turn the system on for a few minutes to let the silicon die heat up thus heating up the tape and allowing the hsf to come off properly.
i suppose AS 5 is so bad that 99% of anyone who knows anything about "do-it-yourself" uses some sort of paste compound.
man you wanna use tape, you go right ahead. but dont try to convince somone who is worried about heat to use it.
just stick with the thermal compound, and you do NOT need to change it ever few weeks.
6 months at best. or if you notice your temps getting hotter for no reason.
I live in a hot climate where it gets up to 48 degrees C. Paste is for temporary installs. You want to use it thats fine but for people that rarely change their CPU or heatsink should use tape. Tape is getting better reaching to 5.4 C/W (I think by The Bergquist Company. Try using a heatgun to heat up the tape instead of turning on the computer.
Just to increase the confusion: I once attached the heatsink without any paste or tape and it worked just fine, even though I have the AMD toaster. The cooler must have a smooth surface, but if paste really helps..I wonder. I use it for peace of mind.
The number of fans and direction of flow depends on the case. Testing what works best is the only way to find out. I use a 2500 rpm fan sucking the air from the processor and a 1700 rpm case fan sucking the air at the back. That's it.
Yes, sanding both surfaces to a smooth finish will increase the thermal conductivity. The finish does not have to be shiny or to a mirror finish. Using thermal tape or thermal paste reduces the chances of oxides and corrosion buildup.
The fan's RPM has nothing to do how much air is flowing. The CFPM is the true value. This value is then reduce if the fan is mounted close to something like a fan grill or a heatsink and lowering its voltage.
