hello im a rookie... i removed heatsink so as to blow the dust away and reinstalled it. A friend told me that there will problem with the CPU !

I had to apply new thermal paste?
I didnt remove the old one, i just removed the heatsink, cleaned it and installed it back again.

I think the advice is pretty clear. If you remove the heatsink, you should reapply new thermal paste. If you didn't remove it while it was off and reapply, you are running the risk of a shutdown.

Follow the instructions provided on how to remove existing thermal paste and reapply it. If you need further instructions, google the process and someone will have it documented with pictures.

yes, you should have re-applied new thermal paste.

as a side note, while it was a good idea to blow dust out of your system there was no need to remove heatsink - dust doesn't collect there.

If you remove the HSF (heatsink/fan) you are going to want to clean off the old thermal paste and reapply it. The best way to remove and clean off the old thermal paste is using some rubbing alcohol, q-tips and some coffee filters or used drier sheets. Wipe away the old paste without touching the bottom of the processor. Then use the q-tips and alcohol to remove the rest. Then wipe off the top of the processor with the coffee filter or used drier sheets. Reapply thermal paste and reseat the HSF.

thermal paste helps quickly and efficiently transfer heat away from the CPU to the heatsink (where it gets dissipated). without paste your CPU is likely to overheat, and if your CPU overheats it could fry itself.
re-apply thermal paste, and don't use that computer until you do.

hmmm, there's a chance you might get away without any ill effects, but it'd be best to re-apply new paste.

You can always remove the heat sink again and apply some thermal paste. You will want to clean it best you can, first. An easy way to clean the heat sink and processor's integrated heat spreader is, cotton tipped swabs and rubbing alcohol. Of course, if you don't have thermal interface material, you can't very well reapply it! Places like Newegg.com and Amazon.com sell it, or any electronics supply stores in your area. The idea is to use it sparingly. It will act as an insulator if you have any more than a very thin film coating the surface. The purpose is for it to fill any microscopic imperfections on the surfaces to bring them closer to flat, not to glue the heat sink to the processor's top. :) On the other hand, if you choose to just leave things the way they are, you'll probably be just fine. You can check your temperatures using a software utility such as CPUID's Hardware Monitor:

http://www.cpuid.com/softwares/hwmonitor.html

You'll probably only gain a number of degrees of cooling by redoing your thermal interface material. If however you have an older style of processor without an integrated heat spreader, gains will likely be higher.

I would check your temperatures before you take all the advice given and become seriously concerned. It is only a recommendation to clean and reapply thermal interface material, be it paste, thermal wax, or other material. Even a bare heat sink will do the job, but the interface material helps the surfaces mate better to increase the efficiency of heat transfer. You're more likely for the processor to overheat from dust collecting in the heat sink's cooling fins than from a lack of thermal transfer material.

ok i just removed the thermal paste ! i used a lotion with 70% alcohol.... i hope its ok... on q-tips! and then wiped it with coffee filter. now how i know if the amount of paste i used is ok ?

btw ( i didnt spread it... i just put the heatsink back and locked it... i hope i didnt mess up :( )

About the size of a pea, on the center of the integrated heat spreader. The thermal paste will spread due to the pressure of the heat sink being locked in place, and will bed-in over multiple heating and cooling cycles. It's not a bad idea to get temperatures before and after you do the thermal interface material to see what sort of a difference it made.

hello back again ... i think after i reapplied the termal paste (i had only done it once again in my life), now the CPU fan runs at 6000+ rpm.... and the room temperature is 24 Celsius. It runs so fast and loud now... it didnt run like this before i reapply thermal paste! You think i did something wrong? It even runs when i play "light" games!

Yes, you probably did something wrong. What are the idle and load temperatures of your CPU? I still maintain most folks here were overreacting to your initial concern about reapplying paste, telling you to "redo it or else." It sounds like it was better off before you redid it.

I would recommend you download and run the free program HWMonitor so you can monitor your idle and load temperatures:

http://www.cpuid.com/softwares/hwmonitor.html

If your fan is spinning at maximum all of the time, your processor is likely running hotter than it used to.

I'm repasting bluejayek's link in case you missed it, to the Tom's Hardware instructions for applying thermal paste:

no its running fast only when i play videogames!! and 6300 rpm is way too much! it sounds like a car :p
The idle temperature now is 17 Celsius.
What is "load" temperature? If you mean the temperature while playing games, i got a 51 celsius max while playing neverwinter , in 26 Celsius room temperature

How i did it :
wiped the old paste with rubbing alcohol on cotton, then wiped the cpu and the heatsink with coffee filters, then waited for 5 minutes and then i applied a bean sized amount of paste! i think i did it well!

Yes, playing games could be considered a load temperature. Basically anything that will throttle the processor up all the way and load it, causing it to produce the most heat. A common program for stress testing your system under load is Prime95, but there are many different programs you can use.

Your methodology sounds good, as well as your temps for air, depending on the processor you're running. I wouldn't worry so much I suppose unless having a car in your computer is bothering you. :p Is it possible you've been into the BIOS and set the fan to run at 100% instead of letting it auto adjust, based on temperature? That could certainly change it's audio profile, if you used to have it set differently in that regard. :)

yes but 6300 rpm! and its not even summer :( i think it started running this fast after i changed the paste ( but not 100% sure). But im 100% sure that it didnt run like this in the past! And its 5 months old only !
I have an amd fx 6300. Is there any chance that the fan is broken now? But if its broken how it runs so fast? :D i guess it isnt

Well, probably not broken, no. Just sounds like it's running 100% all of the time. You could always look in your BIOS if you feel comfortable with that and see if you can find settings for the processor fan. Setting it to auto would let it spin up and down based on the temperature, as opposed to running full speed all of the time. You would likely notice some higher temperatures, but as long as they are not unreasonable, it's not an issue.

Usually, by broken, I would expect a fan blade got broken off from the central fan hub, and the fan is now vibrating something awful! Remember, don't stick your finger in the fan while it's running! :) Has a cord or cable come in slight contact with the fan blades as they're spinning to cause the noise, by chance?
