I hear you, but scanning in store means I save a lot of time. Queues at UK supermarkets are really long. It also allows me to keep an eye on how much I’m spending and spot it when discounts are correctly registered. Unlike what you’re describing about how self scans are received there, they have been accepted a long time ago here.

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.

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.
