PC PSU usage

I have a power supply out of an old tower computer that I want to use for a project. When I fire up the supply the fans in it make a lot of noise. If I remove the fans, will I have any danger of overheating in a wooden enclosure with 2+ inches of space on each side and 2 two inch holes in the wood?

Thanks.

Ben, I don't think anyone should give a straight yes answer to this question as getting it wrong is dangerous. Ultimately you really need to look at how much power your going to be dissipating in the device…

I wouldn't take out all the fans. Power supplies usually have a few key components that get quite hot, and if you don't have enough air flow bad things could happen. However, you may not need all the fans if you're using less power -- check how the air flows through the PS and see if one fan could do the job by itself.

I would also look into replacing the fans with quiet versions. Quiet fans usually spin slower and have less air flow, but that could be OK for your application.
