Why did you decide to measure the sound at 10 cm away?So upon measuring a graphics card at idle and load from around 10cm away, i was given the following readings:

You may get better results at 1 metre away, as most SPL measurements are taken at 1 metre away.

There's various sound level apps for smartphones out, this is what my office (just me in here) reads right now:

If I move/whisper it climbs obviously.
Is that not reasonably accurate enough?
Looking forward to going deaf?
Phone mics will have interference/white noise/static that calibrated sound measuring equipment wont. I wouldn't trust a phone app reading at all.
Most speaker manufacturers quote sensitivity (dB\W) at 1 metre, so I can only assume 1 metre is the closest to a standard distance that it used for SPL measurements.Will give it a go, tried various distances away.
The distance of the measuring microphone from a sound source is often omitted when SPL measurements are quoted, making the data useless. In the case of ambient environmental measurements of "background" noise, distance need not be quoted as no single source is present, but when measuring the noise level of a specific piece of equipment the distance should always be stated. A distance of one metre (1 m) from the source is a frequently-used standard distance. Because of the effects of reflected noise within a closed room, the use of an anechoic chamber allows for sound to be comparable to measurements made in a free field environment.
Yes with dBs you just add and subtract them, when you convert it into linear units you cant just add and subtract.
