If I just want to replace the processor do I have to replace the fan too?

I found that I can replace the processor myself but purchased the wrong one for the motherboard that I have, now sending back and will reorder and in looking see that I can just purchase the processor itself, do I need to replace the fan/heatsink too?
Have now done my research which is what should have done earlier and now know what to buy. Will be purchasing an AMD 2+ processor..

Most AMD processors will come with a stock heat sink. As for the old one does it line up with the mounting bracket on the board and what size is it? If it does not or is too small then yes you may want to send it back for a different one. Most places accept "I bought the wrong one for my processor." as a valid reason fror returning a heat sink.

I have run AMD's for a long time; one of their strong point is that the sockets don't change very often.
If you are buying an OEM processor, that is, just the CPU with out a heat sink, then your old heatsink should fit as long as it was originally for an AM2 or newer board/socket. If all you are concerned about is the fan on top of the cooler, that will depend on the actual 'bolt/screw hole pattern' on the fan.
HOWEVER fit is NOT everything: The heat sink and fan have to be able to adequately cool your CPU. Just because it will fit the socket doesn't mean it is engineered to cool the new CPU - especially if the new CPU is faster and or has a higher TDP (power) rating.
You might want to consider buying the ' boxed ' retail version of the new CPU, and make certain it will fit your board. It will come with a cooler adequate for cooling a stock clocked (not overclocked) processor; all you will need to do is install it.

Thank you very informative,
now looking for the boxed version of this cpu.....a little history here....I am trying to acquire a work from home position and my pc passed everything except that processor an AMD SEMPRON 140 and 2700 MHz single core both Failed they require at least core speed of 3.0GHz or 1.5GHz for a multi core chip so this what lead me to you all for more help!
I just want to upgrade to pass test and get job then will be purchasing a newer pc later.
The one I'm thinking of getting is this one....is this good enough?? The only thing is mine is 95W, does that matter? I don't think I can go over that one, huh?
And also after reading some of the other posts, I see some recommendations of reinstalling OS's, will I have to do that too?

Well, I can't answer that with the amount of information you have provided.
So please, post your Motherboard make and model
Your current RAM specs: DDR, DDR2 or DDR3, brand and speed (800, 1333, 1600)
VERY important: your current Make, model and specs for your power supply. It should have a label on one side
that lists all of that. A picture of that label would be good, but at least post the info.
Make and model of your video card. Neither your old processor nor your new one have integrated video, and your video card may be the largest consumer of power in your system.

My initial feeling is that this will work, but to confirm that would like to see the info above.
If I may ask, how much are you paying for that new CPU? There might be better CPU's available for the same or less cost

AngelGryl, the specifications that HP provided already tell you what processors your very old motherboard will support: "NOTE; only AM2+ processors are supported with this motherboard."
You are trying to buy a cpu designed for an AM3 socket, and though there are some mobo's in which that AM3 CPU will work (usually after some critical tinkering with the BIOS - which if done wrong can Kill the mobo) it may not function well with your memory (you have DDR2 and the AM3 normally uses DDR3) and HP themselves have told you their mother board will only work with AM2+ CPU's. Look at the list they have provided; it tells you what will work.
For the most part you will have to shop ebay to find those old CPU's as they are not in production anymore.

Sorry, but this doesn't tell us very much. Please look at my request for information: YOu have provided perhaps the most significant piece of info; that you are trying to upgrade an old pre-built HP machine. It can be done, but is it ultimately worth the expense? If this is your first adventure in upgrading/building we can try to help, but experience has shown that simple upgrades usually are not simple; upgrade one part, and you find you have to upgrade another, then another, etc. to get the PC to run stably. Don't know where you live, and can sympathize with budget problems, but it might be simpler, less frustrating, and overall cheaper to just buy a new inexpensive PC.
If you can find one of the CPU's that HP listed, then the upgrade path IS simple and should work. If you can find one new and a boxed edition, it will come with heatsink, fan, CPU, and the Thermal Interface Compound (thermal 'grease' or TIM) already on the heatsink so installation will be simple.
If you end up buying a used CPU or an OEM CPU - that is simply the processor - no fans, heatsink, etc.- your old heatsink Might work with it (it should fit, but the question will be whether it can conduct away enough heat) and you will need to purchase some TIM (I recommend Arctic Silver 5 or Tuniq 2 or 4). Here's a link showing how to properly clean the heatsink & cpu and apply the TIM. (It looks weird when you open it, but checkout the article)

Sorry for the long discourse, I hope it helps.

NoInstall,
Thanks for all the info....got it. Yes, following what HP recommends on this one. Ordered an AMD 2+ cpu from Amazon and gonna use the fan heatsink that I already have. Got it right this time.And you're right, in researching found that I would basically be building a new pc from scratch with all the extra add on's that I would need due to wrong cpu being added. not worth it to me. All I need is for this to get me up and running for a short time then will be purchasing a new pc cause this is wearing me out! LOL! And already have the TIM cause had to clean and reinstall my old one back in system, although am considering just purchasing a new fan.
Thank you once again.

GREAT! Glad you found the right CPU, it should work well.
You might try contacting HP or even AMD to see if they will either send a new fan or sell you one for a reasonable price; that way it should match the heatsink. Few years back I thought the fan had broken on my Phenom heatsink and AMD not only replaced the fan, they sent a complete new heatsink and fan. Hell, it's worth a try.
