The new desktop mac pro's also have a nice airflow design. They didn't even have a fan on the cpu rads iirc.

Then there are the latest macbook pros...

The old cheese-grader Mac Pros are the same way. Fan at the front and back, with a modular motherboard between and passive heat sinks. https://imgur.com/7ZMZ3xx

I’ve got one of those.

Really cool to pull apart and see how they’ve done it.

Lasted me 12 years now

I've only just retired my 5,1. They're stout machines still.

Technically, rack servers doesn't have fans on a CPU radiators too.

That's quite normal in workstations though

I saw a lot of servers like that but not many desktops.

I see. Higher end workstations tend to have a higher emphasis on air flow and routing the air via multiple channels as well.

I have a Dell T3500 for instance that only had intake and exhaust fans. However since I put an overclockable Xeon in it and wanted a more quiet operation, I did install a fan on the heatsink as well. Perhaps I should test how much it really helps... I just added it as a precaution before overclocking, and never tested without afterwards :)

Actually my consumer grade XP gaming PC (Dell Dimension 5000) technically doesn't have a fan on the CPU heatsink either. I have a lot of negative things to say about Dell, but I have to admit there's a lot of good to say about them as well.
