Good news - we're open for limited services in Wembley. Ujima House is now actively under refurbishment and we'd love your help in making the space the best it can be.

Project:Passive cooled pc
It's forever bothered me how much noise desktops make. Fans just seem to blow the air round and round and the general setup seems poor.
Design and hack together a better setup, with large heat sinks on the exterior and heat pipes to move the heat energy away from the hot bits. Plan is to engineer to the worst case scenario of hot, high end CPU and GPU running on a warm day.
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|
|GPU fan:||10 dB|
|CPU fan:||5 dB|
|0 dB||Threshold of hearing|
|30 dB||quiet bedroom at night|
|60 dB||conversational speech 1m away|
|80 dB||beside a busy road|
