Noisy case fans

New machine all in h6 flow

Not much on the web. One guy i thought has similar issue but it isnt the mesh panel.

When i shut down the machine the clicking stops as soon as power is removed even though the fans are still going from their own momentum.

All three exhibit the same.

They are voltage regulated. Ive tried all three into one header and all on their own headers.

Any ideas? Or just junk fans,

Ok. I think they are just junk 3 pin fans.

cases, even expensive one tend to have cheap`ish fans. If you want some good ones get Noctua fans but like everything good they are expensive.

Thanks. Writing this post helped me process it. The case was 69£. It aint going to have good fans… but surprisingly useless i didnt quite expect.

Will order some p12 pro. Think they are good and cheap i hear

That rattling certainly wouldn't help.

If you won't want to spend a lot, then the Arctic P12's or P14's (depending on size needed) are viable cheaper options. Just be aware as you're likely to want more than just one fan, you can buy them in a pack (x3 and x5 I believe) so make sure you purchase the amount of fans you want to fill your case and buy accordingly. Note, having a spare fan in case there's a dud or one that develops a dud is always useful.
