Put a block of ice on my passively (via a large block of metal) cooled router since it's hot today, and yup, impressive how the cool-ness stuck around after removing it

@benjojo is your room temp around 30C?

@ignaloidas sadly yes, the UK is hella hot right now

@benjojo isn't doing that a bad idea because it can lower the temperature below the dew point and cause water to condense inside the router?

@noisytoot the router can have a little cool off as a treat

(Yes you are right if you do let it get below the dew point, simply don't do that)
