[time-nuts] 53132 replacement fan

[Tom Knox]

Hi All;

Mouser has more then 200 of the EFB0412MD OEM fans in stock. 10.93 in singles.

I have so many fans running in my lab I do not worry much about a little more noise. But a noisy fan is a major concern because of overheating if the fan fails, and although I usually go for an OEM parts in some cases with product that generate a lot of heat (especially product where I have seen heat contribute to failure) I will go with a more powerful fan.

Cheers;

Thomas Knox

Thanks, all for the tips.  Glad to know it's a standard size so there's
plenty of choice.
