After building my new computer, i realize how silent it was, then after playing some games and such the heatsink seemed to run faster and was louder. i figured it was normal seeing i was using my computer more. but it never got quite again. Now it is extremely loud and quite annoying. Is there a way to solve this without buying a silent heatsink.

first off it's the fan not the heatsink second have you checked to see if something isn't getting down into the fan blades? How about dust? could be that the fan is going and needs to be replaced.

yeh :-p i meant the fan. but it is a brand new heatsink. i went into my bios, turned on cool and quiet, it became quiet. then it becomes loud randomly. assuming when it has a lot of work to do

About the only thing I can think of is you could try reseating the hsf and reapplying some heatsink compound. Just be warned that if you have a retail processor that you may void your warranty if you do this. NOTE: if you do this you need to clean the processor and heatsink of all the old compound and reaply some new stuff in a thin a layer as possible. When I did this it dropped my temps about 10 degrees which might keep your fan from spinning up so much. Good luck

Or get a quieter fan or a new hsf. If it is a stock hsf it will get pretty noisy if it is running at full load there arent many hsfs that dont, most people dont notice it as it is usually only that load if they are playing a game and alot of people listen to music whenever they are on there pc.

Good advice, but one clarification -- if you do this right, the heat from the processor will be more readily transferred to the heatsink. The processor will be cooler than before, but the heatsink will be hotter (this is a good thing). Whether the fan slows down or speeds up depends on where the temperature is being sensed -- could be inside the chip, or on the outside of the chip (inside the socket), or on the HS (mostly older MBs).

Also have a look at your video card.
Some like my Matrox Millennium P750 triple output, have a fan on it, this is also a heat sensitive fan.
I mainly use this for 2D Autocad, but on 3D stuff, the fan makes more noise than the CPU and power supply together!

I actualy got an other fan that is less noisy and partly solved the problem. I will install a duct from it to the exterior of the PC

ok I had a problem like this..... I bulit my puter and had a thermaltake volcano 6 cu + heat sink fan that ran at 7800 to 8100 rpms niether to say less it sounded like a valcum cleaner from the other end of the house after 12 or so months the noise finially got to me. I went out and bought a gigabyte G-Power coolerwith a bigger fan and 4 heatpipes.....WOW what a complete difference..... a lot quieter and it cools alot better. I have a amd 1800 overclocked to run at 1.9ghz and it runs idle at 27 degrees c and with a load on the cpu it runs 35 degrees c . the fan has a 110mm fan which alows more air flow with less noise. I would say getting a new heat sink and fan or see if your heat sink will upgrade to a bigger fan.
