We have a floor standing server cabinet, which sits in the corner of our office. There is no AC in the office, and the average temperature is around 21C (70F). The server cabinet currently contains 2 tower servers, a switch and a router. It's well enough ventilated, but does get understandably warm in there.
We've recently put a thermometer in there to monitor the temperature, and recently I've noticed the temperature hit 33C (91F). What I'd like to know is if this temperature is too high, and whether there is a maximum temperature we should not be exceeding?

It's recommended that you keep an average temperature between 20 and 21 degrees, but you can vary between 10 and 27. Going below or above that is not advised, so yes, technically 33 is too high.
The real question is what is your inner case temperature on your servers. Usually server rooms have 1U/2U servers not regular tower servers and that's probably what those guidelines are based on because they are much closer together and share heat.
Purely from a "server room" perspective it's too hot; but for the towers check what the case temperature is (with a free app or something) and check the recommended values.
