Suggestion
You might gain a slightly cooler engine compartment but in the meantime the alternator might run hotter since the fan being on all the time means a bigger electrical load.
Leading evidence: 'Run hotter since the fan being' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Run hotter since the fan being' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

When you get back in the car after it was run a while before being parked if the intake air temp is 135F or higher then fan should come on) is to leave things alone.

Suggestion
My guess is your engine is just running well and not creating a lot of heat to set off the fan.

Suggestion
I thought I had an issues as well, but after testing all of the components it seems clear that everything is working as intended and that it's just not hot enough to trigger the use of the fan.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

It's very rare for the compartment to get hot enough for that fan to come on. I thought I had an issues as well, but after testing all of the components it seems clear that everything is working as intended and that it's just not hot enough to trigger the use of the fan. Why do you want it to run?
You might gain a slightly cooler engine compartment but in the meantime the alternator might run hotter since the fan being on all the time means a bigger electrical load.
Sure it is your car and you can do what you want.
But my advice is if the fan is otherwise in good working order and comes on when it should -- when the engine compartment reaches 135F (IIRC) (and you can sort of keep an eye on this with an OBD data logger/data viewer that lets you monitor intake air temp. When you get back in the car after it was run a while before being parked if the intake air temp is 135F or higher then fan should come on) is to leave things alone.
Also, regarding the compartment fan: It may come on but you may not hear it. Even with the car at a standstill I can barely hear the fan come on in either my Boxster or the Turbo. Once the car is moving forget it.
Sincerely,
Macster.
If the compartment fan isn't coming on then your engine and compartment are probably not getting too hot, which is a good thing. Although, depending on the situation I wouldn't necessarily rely on only the DME setpoints to activate the fan.
Given where the engine fan is located wouldn't you be countering the natural flow of air into the engine ?
We run in the same temperatures and I have only had my fan come on once.
From logging I can tell you that anything above 55km/h pushes air into the engine compartment and keeps intake air temps down
There could be the off chance that the engine bay temp sensor is either NG or out of place. It's located between two cyl intake ports on the passenger side and has a rubber washer around it to hold it in place. Sometimes the sensor slips out of place and dangles down away from the engine giving false readings due to cooler airflow away from the engine. My guess is your engine is just running well and not creating a lot of heat to set off the fan. I've only had my fan come on after running at a track day and having to shut down from a red flag without getting a chance to do a cool down lap.
