Those were the old days.....more and more they're using standard equipment (to save $$) and are building around it. They just slap their name on it. These are socket 771.

I do agree that water is the extreme solution in this case. I would prefer that Dell just fix the issue but thats not going to happen. I have been asked to fix this and I will

I'll probably try some aftermarket heatsinks first.

Even with additional cooling, the computer will still put out the same amount of heat, which is ALOT of heat with the amount of hardware (100GB ) being run. I really think high end air is a much better option. All it takes is one of those two hundred rigs to spring a small leak and there goes $20k+. Also better airflow (more fans) will help with getting the heat out and away from the heatsink, as well as bringing cooler air in.

Don't get me wrong, water cooling is great for a personal computer you keep in your room everyday. You know it inside and out and are aware of the symptoms that something is wrong, employees don't.

I don't think the whole 'leaking' issue should come into play if the loops are assembled properly..

Since it sounds like OP doesn't have a choice in the matter of giving water a shot, I'd say look to consolidating where you can.

If it were me, I'd look at it as a holistic approach. There's 200 computers that need to be cooled.. Are each in separate offices? how likely are they to be moved around? You may want to think about interoffice plumbing once the whole thing is running.

If the offices are in a cluster, which it sounds like they are if they were talking about ducting throughout the offices.. I'd put:
Radiators in open areas, or outdoors if that's possible and pumps and manifolds in some sort of controlled access space

Finally, I'd run pipe throughout the included offices and allow for a quick connect system to the computer, which just has some tubing and waterblocks contained inside it.

This approach does a few things:
-keeps the heat out of small offices (heat that just ends up back in the loop)
-simplifies service (technician simply removes waterblock as any other heatsink rather than draining a loop and needing to know all about watercooling and feeling, and bleeding, etc)
-can help to heat open areas (hallway, lobby, etc)

Thats an interesting approach but the whole reason for keeping them internal to the desktops is to avoid office construction costs. Plumbing entire office floors seems like the extreme of extremes to me

In an office setup with this many EXPENSIVE computers, water cooling really is just too risky. In the long run, the cost of maintaining the systems and repairing the damage that could potentially be caused by leaks (or a faulty pump) outweighs the benefit.

Now, if your boss understands this and wants to do it anyway that's one thing. But I advise you to look into a good air solution as well to give him more options. It doesn't have to be a $50 TRUE for each processor, just something that would fix the problem.

Definitely not worth it in a corporate environment. Why? Because air cooling is cheaper, safe and more user friendly. Assuming you aren't the only person who carries out maintenance on these machines, how will the others cope with water cooling? Ask dell for solutions as any corporation paying $20,000 per machine will have on site technical support.

I would say buy quiet fans that move a lot of air, and replace case fans, and buy high end air HSFs. water seems like extreem overkill for that, given that they are running stock and the massive number of computers.

So here's an image of the open case for ya'll to snicker at.
As you can see they are passive heatsinks (i removed one of them) with 3 heatpipes. There is a plastic shroud that covers the bottom half of the case essentialy creating a wind tunnel of sorts blowing from left to right. Nice idea but there are all kinds of big open gaps for the air to go around the heatsinks instead of through.



What I'm going to try first is getting a couple of these....

That decision is based entirely on the fact that those coolers will fit in the tight space side by side. And they are active.

wouldnt just sticking some fans to the sinks help? they look quite capable
