Anyone give me a link to a suitable fan to fit to the top of my little Kl203p ? Bought one fitted it and found it’s just too noisy ! Don’t really want to add any extras to slow it down etc so will just try pick up a quieter version.
Anyone ?

I use 120mm “uphere” fans on 503’s etc dead quiet
From Amazon
They might do a smaller one for 203

Try a 12V PC fan on 5V. It'll run slower and quieter, and it might just be enough to keep everything cool. I use one on my main PSU, as it runs all the time it stops the PSU getting hot instead of having to cool it down.

Faster a fan spins the more noise they make. I find a decent quality 120mm fan spinning around 1150rpm is a good balance between cooling and noise. Noctua fans are very quiet but not cheap.

Agreed I too used smaller fans at reduced voltage but latter discovered a larger fan was far far quieter

Re: Quiet 12v fan for kl203 amp ?
Yes smaller fans have to spin faster to be effective hence more noise, bigger the fan less rotation needed. Other factors can add noise though such as blade design / geometry, bearing type, if blowing air through something or onto something. But overall its a either about cooling efficiency or noise.
