Basically just the CPU fan, case, and PSU (if you’re lucky). If someone can figure out how to get Doom running on just those 3 things, young people will be able to ascend.

Don’t be sorry because you’re not wrong and dude was just being a dick for no reason. Also a PWM signal is not a complex concept and it certainly doesn’t require any degree at all to understand.
Simply put: you have an additional pin carrying the PWM signal, which is a simple squarewave. How much of that wave is high during a period is called the duty cycle and regulates the fan speed. Eg. if for 75% of the period the signal is high, then the duty cycle is 75%.
So, while the phrase “they spin what they are ordered to do by the PWM” is not particularly well worded, it’s also technically not wrong.
I really wish people would share their knowledge, instead of gatekeeping it to feel superior.
Ty :)
So the fan decides the max RPM possible and the fan controller (probably the Motherboard) decides the percentage of the available RPM with the duty cycle?
Pretty much. In a typical motherboard, the fan controller is linked to temperature monitoring and the duty cycle is changed in correlation with another variable, generally CPU temperature. The PWM control method actually doesn’t require the monitoring of fan speed at all, but it’s included for informational and safety purposes.
The username was a bit of a giveaway.
Their claim about Noctua is also not correct, or at least not generalisable to all coolers. I upgraded my CPU recently to a Ryzen 9 5950X, so needed to upgrade my cooler. The NH-D15 came out as one of the best options (that were also available second hand) when looking at cooling performance per dB. That ratio is what matters.
I ended up spending about $45. It ended up not having all fan clips with it, but Noctua sent those to me for free.
If you’re going to infer someone is stupid because you disagree with them, at least have the decency to explain how they’re wrong.
BTW, the username is 100% bait: a certain fraction of social media users tend to make that “hurr hurr, username sure checks out” comment, letting me know the person making said comment likely isn’t worth taking seriously.
It was a joke I assumed you’d be okay with given your username, which signalled an appreciation of self deprecating humor :)
To be frank, I didn’t think you were friendly enough in previous comment that I wanted to engage with you, but I had something useful to say. So I referred to your username as hook for the other discussion. I think the person I responded to did a good job explaining why the PWM comment was technically correct, so I had nothing to add to that.
But other than the comment you made I thought could have been friendlier, I have nothing against you. I’m not making any inferences about you as a person based on one comment. I dont actually you’re stupid, you’re still the stranger on the internet you were before.
I wasn’t being a dick for no reason - I was being a dick because I thought THEY were being a passive aggressive dick, much like how you assumed I was “gatekeeping knowledge to feel superior”. Bad assumptions all around here.
I assumed they were suggesting PWM will cause an inherently slower spinning fan to spin at any RPM regardless of model, which is actually a response some Noctua diehards have used in the past when I point out what Noctua is omitting when they advertise their fans as being so much quieter.
Regardless, I apologized for my bad assumption and subsequent response. It was out of line, especially given the actual meaning and intent of the comment.
