Disclaimer: I read HWCooling like everyone serious about the subject. These reviews aren't everything, the appalling QC that results in resonances or coil whine lottery isn't mentioned.

In general, yes, Noctua is overpriced and Arctic is an incredible value, but when you want to optimize your silence/performance ratio, it's still Noctua, BeQuiet or (sometimes) Thermalright.

> coil whine lottery

This was a fun revelation when I got into watercooling. You might not hear coil whine over a gpus fans. But remove the fans and put it under load and whoo boy.

So this confuses social media discussions on the topic by mixing together everyone's reports, regardless of their level of acoustic masking. "My card has no whine!" says the guy with three 2000 rpm fans going etc.

Gpu waterblocks seem to be shifting towards fully enclosed "tomb" style and I can't help but wonder if coil whine contributed to that decision.

But on topic, I had seven a12x25 in my last build, two a12 and four a20 in my current build. They are exceptional. A computer is as quiet as it's loudest part. If your care about noise, why would you ever skimp on the moving parts.

I think GPU waterblocks are becoming fully enclosed because there are so many hot components on the back of the GPU now. They were designed to rely on random case air turbulence to passively cool, but there typically isn't much airflow over the back of the card when the stock cooler is replaced with a waterblock.

Problem becomes worse when the cards are driven harder because there's more cooling capacity from the watercooling in the front, but the passive cooling capacity on the back is still the same.

I used to stick a giant fin block on the back of the card to keep temps there reasonable. I'd love it if actively cooled backplates become the norm for watercooling.
