The Desk Made of Radiators can cool ANYTHING

[AlexTheGreatish]

Normally your desk just holds up a computer... But what if it cooled it too?

now try a radiator made out of desks 

[Middcore]

Redd this as a desk made of Redditors.

Going back to the video where you used a much larger pump to force water through a CPU block and did notice that more flow affects performance.
That did make me curious, would a setup like this desk perform noticeably better if the rads were all in parallel?

 

It is a lot of radiators in series, so it would be a a fair bit less flow resistance for the water, and all pumps have lower flow at higher flow resistance. _{(unless it is a fixed displacement pump running at a fixed RPM, since then it just needs more power from the motor.)}

 

But other than that it is an interesting desk idea.

The only things I would add/change would be a Flow meter or 4, Just so you can keep a EYE out on the Radiator flow.

And make the desk deeper so its around 80CM deep, as I like a deep desk.

As a sound tech those janky mods in professional applications are the best things to think and laugh

Just don't use it as an eating surface. Unless you want chopped Cheetos all on your crotch.

That's just the new "Whopper-Chopper" feature it has - Chops ANYTHING that gets too close.

BTW is your desk leaking or did you just pee your pants?

Not sure I would trust that pump/res combo for long term or even 24/7 use - with that many 90 degree fittings even a D5 will have a hard time and it's not something you want to run on 100%. My D5 has been running 24/7 for the better part of SEVEN YEARS, but that's at a set 80% duty cycle (#4 on the pot). I run 5 blocks and 5 rads but only have a single 90 fitting in my system - everything else is either dual 45 or soft tube bend.

 

I would have done this desk way differently and it was an idea I actually pitched to Alex some time ago, although I can understand you guys just don't have the time (and resources) to delve into every user submitted project. Instead of using thin rads all across the table top you use those chunky 80mm thick ones outboard along the edges - significantly more cooling capacity and you can actually keep cool a server worth of CPU and multiple GPU easy. You incorporate a monitor stand that doubles as a massive tube res adding to the coolant volume to help dissipate the heat. As for power supplies, strap four 1600W units upside down underneath at the back, nicely cable managed along the rear and with enough juice to run ANYTHING. Then for the legs of the table you use a UPS+battery. Finish it off with a smoked glass table top, some well placed RGB and you have a workstation unlike any other.

 

And it's not made of steel/metal either - standard 5.5x1.5 wood beams just cut to length and simply bolted together using 0.3x3 hex head fasteners. No drilling, no stripping. I have my TV stand done exactly like this holding a 55 inch panel on a swivel mount and it's rock solid. Just a wood H frame mated to an inverted T - very strong. The same wood beams would form the feet of the table, and to handle the weight and make it movable, place four casters on each corner. Run some angles on it with a planer and apply some wood stain/varnish and you have a real furniture piece too. Working with wood is SO much more satisfying.

Turn fans around for summer.

Run rads in parallell.

Add a second pump.

Run fans at low rpm all the time - there is enough cooling that you don't have to ramp them up as long as you don go for totally passive.

 

Would really have liked to do something like this - but I already put my rad outside instead

You're overestimating how much flow is needed and underestimating how strong a D5 is.  The rads by themselves are probably less restrictive combined than a single CPU block.   I've driven my desktop loop at 90lph and it was very minimal change going up to 275lph with everything cleaned.

[Olaf2k4]

This whole concept would be way more interesting with normal hardware , like a 12700 / 5800x and a 3070 . Also putting the fan in the rear would probably help  

[JordNL]

Not only did I foresee already that this desk would be anything but cool (temperature not "sweet"), but I think after a while (painful) indentations will be noticeable on your hands and arms where they rest on this desk. Doesn't putting on a large mouse mat hamper the cooling at that point because the hot air at that point can't go anywhere?

Probably because REALLY BAD THINGS HAPPEN when you underestimate the flow and push your pump too hard  Granted in this scenario the rads are all at the same level so the water doesn't really need to travel much vertical distance. Regardless every 90 degree fitting you use will take a hit on a pump's head pressure. Water will still flow but it will have a difficult time making it back to the pump. That's a typical sign when the weakest seals start to leak (and especially seals right near the pump's output rather than near it's return at the end of the loop). It's also why you don't want your pump "sucking" on the return - water should flow into the pump from the reservoir on it's own. Ideally you want a high-flow low-pressure setup so water can circulate quicker between the hot and cold points and have a more even strain on all the seals in your loop. That WILL depend on the complexity of the loop - mine requires a #4 on the pump to run properly, yours probably runs fine much slower. More coolant volume = more work for that single pump to handle.

In the middle of summer in AZ, it's cooling to stand under the exhaust of the metro train computer, even though it's the same air you're standing in.

[Apprisco]

Honestly I really just want the CAD file lol

[rushboarduk]

To be honest, I am surprised people who make ergo system desks haven't tried something like this, especially if you are an Indie developer doing Virtual Production workflows with multiple 3090s running. Licensed from Protocase, the Red Harbingers and FlexiSpots of the world could probably turn a tidy profit from selling them in small batches. You could even use hard glass tubing with coloured coolant, or gold/silver tubing and fittings mixed wilth RGB fans to create some great configs.

 

I envisage only two flaws in making it retail-worthy. First, carry handles mounted each end would make it easier to move after a system is attached. The second is the desk obviosuly gets REALLY hot under load, so a separated glass layer would still be needed to rest peripherals (and your arms), whilst improving the aesthetic.
I would also set the fans to turn on at maybe 40-50 degrees; that way the desk would still be hot, but less likely to burn your hand...

 

I know Linus baulked at costs, but most decent, ergonomic chairs cost as much as $700 minimum. This desk is completely doable, and I'd definitely pay for one.

@AlexTheGreatish

Carbide drill bits bro, they're not super expensive and will drill through hardened steel and any other metal you throw at them. There's HSS shanked bits with just carbide tips made for metal drilling that can just chuck up in a hand drill and go to town with.
