Hello.
one of my fans has died and I’m awaiting a replacement. The machine is getting very sluggish on mediocre tasks. Is this relating to only having one fan?
Out of warranty so looking here before I go to Apple.
Is this a good question?

There is a fan for the CPU and the other for the GPU, if the temperature of one of them rises to a certain value then the system will lower their frequency to prevent them from burning and as a result you will notice lower performance.

Lets get a better idea on what's happening. See if you can run the onboard diagnostics. Restart your system and press the D key so enter. Tell us what the error code is.
In addition lets see whats happening with the fans. Install this great App TG Pro it will allow you to see the systems thermals and fans. Post a snapshot of the main windows (you may need to grow it to get all of the sensors to show and the fans) Adding images to an existing question

@danj Just that could not find left ran which is presumable as their is currently no left fan in the machine (its in the bin!)
