    right, feel free to move this. ive no idea where to put it.

    i have a noisy computer. my fan should be operating at about 36db, but its so goddam noisy. so i want to find out the level.

    i am looking for a programme that can take the mic input and give me a db reading. ive been searching on google and a few download sites and no luck so far. ive found a few programmes, but they are for professionals with db readers that can interface with the puter.

    any help is appreciated.

    dw!

    hmm a program to measure db level .. well ye could look at siasofts smaartlive but thats costly and ye have to buy a measurement mic and a calibration unit. Ye can pick up a really cheap db meter from RadioShack in da US, which would be yer better option but its not very accurate, but fer your use it would be fine.
    why not just get a water cooling system..?

    I'd assume you need to calibrate a device like that. I'm sure someone here would know. http://www.silentpcreview.com/

    Sometimes just cleaning the fan will reduce the noise level. I had a PC to fix last week - the CPU fan was very loud ... blew out the dust ... and it went silent ...

    Must have been noisy dust...

    drrnwbb - disconnect things like the HD and CD's and then case fans, graphic card, and until you can determine which fan is the noisiest and then replace that one. It could be the PSU fan, the CPU fan, the motherboard fan, or the graphics card fan. Anything over 30db, over 24 is loud and under 20 is very quiet. Make sure you note how much air the replacement fan moves, or if its a heat sink how well it cools.

    Are you doing all this to check if your fan is too loud?

    I'm not sure why he wants to record it though. Is it a work computer or something?

    hehe, i know its too loud already :) just curious to see how noisey it is in relation to how noisey its supposed to be (30db).

    but some xmas money came today, so i am gonna go down to a local puter superstore near me and see what they have.

    Sometimes the bearings get dry, and if you lubricate them it quietens them down. Or they become unbalanced. In which case you'd need a new fan. Just be aware that a lot of fans and heatsinks that are advertised as quiet or silent are actually not that quiet.

    Be sure to check a review on the web before you buy something. A good fan should be about €25-40.
