+'''The Challenge'''
+Did some noise testing on my machine, taking out the different parts and measuring noise levels, here's the results:
+{|
+|Totally off (just background noise)::
+|34 dB
+|-
+|Everything on, idle cpu/graphics:
+|56 dB
+|-
+|No GPU:
+|46 dB
+|-
+|No GPU & No HDDs (3):
+|42 dB
+|-
+|No GPU & No HDDs & No CPU fan:
+|37 dB
+|}
+Meaning each component makes roughly this much noise:
+{|
+|PSU Fan:
+|3 dB
+|-
+|HDDs:
+|4 dB
+|-
+|GPU fan:
+|10 dB
+|-
+|CPU fan:
+|5 dB
+|}
+For reference:
+{|
+|0 dB
+|Threshold of hearing
+|-
+|30 dB
+|quiet bedroom at night
+|-
+|60 dB
+|conversational speech 1m away
+|-
+|80 dB
+|beside a busy road
+|}
