Here's what someone else did with their (similar model) unit:

Thanks David. I looks straight forward but I have tried searching for the part number that he uses but have been unable to find it.

Could you suggest a local place I could try to source the part please.

Also from that video you can not actually see that fan operates properly after the thermistor is installed.

I can make up a board for you and bring it to the mini if you like. Are you in a hurry?

In the clip he mentioned part number KSD01FD45 (45° C trip point) thermal switch. When I checked last, Digikey had them for about $10 I think. I found this one just now but it says ERROR for QTY and price.

EDIT: The KSD01F part is found on eBay, but they are NC (normally closed) versions, not the NO (normally open) ones that you'd need.

Here's a link to a different version of the temperature switch:

It would be an easy mod to do.

Thanks David - I had been wondering how that was going to work with an NC switch (which is all the ebay search ever brought me until now!)
