Succinct yet still reasonably detailed analysis of the poor chassis thermal design issues in the Dell Optiplex GX260, GX270, GX280 era desktop clamshells, amplified by some flawed design choices in the CPU fan. Includes some actual temperature testing which, while not detailed, shows they do a nice toasty 60C internal at idle and 67C at load… aka ouch.

Not to play devil's advocate, but does it matter? These are basically designed for business/office use, and even if they run warm as long as everything is within spec it shouldn't be an issue. Of course, they're plagued with bad capacitors, but that hit every computer of that era.
Yeah i'm pretty sure this was the exact era and why i just threw any machine like this out year later.

But also while 60 and 70C sound really really really hot today. Remember everything in that era ate power like no tomorrow and it was in the days of throwing more power at it to get more performance. But to be honest without that era you wouldn't have all the push for better Cooling products coming to the market. Remember people putting on like 2 pound copper coolers before motherboard back bracing was a thing?

Apart from being of the time and thermally terrible, are these vintage Dells worth keeping around? I found two in my basement, and I already hear the siren song of electronics recycling drop off, that won't start for another month.

One of them is a Pentium D, which should double as a space heater.

You could always open them up and see how many caps have failed before recycling them.

Nothing notable from this era. The previous gen with the P4 1.8 was if you're into keeping somewhat notable processors. And the next notable is stuff from the Core2 era.

Ewaste it now before they make you pay to ewaste it! This of course is your locale if this is an issue but getting rid of it before anyone proposes it as a way to make revenue is the best option.

Hm, what’s notable about the 1.8 ghz P4? I had one back in the day, one of my first PC builds.

Overclocking. Like the Celeron 300A. It got pretty high QC rates from it's price point. Along with all the motherboard manufacturers having a solid footing for that era at the time working out the previous transition headaches. Not saying the best. More notable as it lets you experience everything without instantly frying the components providing you didn't get pre-toasted equipment. Then it all languished a bit until the Core2 Q6600 from my memory.

Dell are still selling cases as bad as or worse than this.
I have an Alienware case that's even worse than that. It's mostly toolless, but such a massive PITA to work on. And there's so much ridiculous, unnecessary framing to support the internal components that there's very little room to put things.

I bought it because it was the only way to get a GPU at the time, but dear lord, never again. I'm using the machine as my Proxmox host, so it's not worthless, but it's an execrable design.

Friends don't let enemies buy Alienware.

I'm sure it cools well in the environment it was designed for. You know, where it snows carbon dioxide at 1bar.

Stumbling across this thread I honestly thought this was necro'd from 2004 then scratching my head and saying "hang on, youtube wasn't around then"

Given the history of pre-Core CPU's, none of this was news even back then anyway

I'll have you know that NetBurst was news ... certainly not good news but it was news. And don't even get me started about RDRAM.

We got pallets upon pallets of replacement motherboards for the Dells we had on our campus from that fiasco. I swapped out hundreds of them.
I resoldered dozens of caps on failed servers and server I/O boards a few years back. Had several servers drop their arrays due to a failed 1500mF cap on their controllers, and I figured out that you can tack on a 1000mF and a 500mF cap (I couldn't source any 1500mF caps locally) to get 1500 mF total. Was a hero for a while when I recovered hundreds of GB of data.
That was back when Frys and Radio SHack were around. Now I don't even know where I can buy caps locally.
