We Hooked This up to a PC

We've had some bad ideas before, but hooking a 2.5HP gas powered pump up to a computer has to be the worst.

An adjustable wrench won't round a nut if one tightens it up before one starts wrenching. (unless one applies a lot of torque, but then a regular wrench also starts to round a nut. (though, if one's adjustable spanner is cheap crap then it will round a nut as well)) Also, the "lot of pressure, but not a lot of flow" isn't surprising, long thin tubes generally makes for a lot of flow resistance.

 

But interesting to see how the cooling performance increases with flow speed, not all too surprising but interesting to see how much it did to be fair.

 

Now, mind if I toss a "stupid" idea out into the ether?

Add a chiller (preferably a large one, or a bucket full of dry ice) and fill the loop with methanol.

That was awesome! Here is a link to the Holley Fuel pumps I was mentioning on YT. They flow up to 323GPH at 8psi & 13.8v thru a -10an line

VR2 Data sheet

 

Holley Brushless Fuel pumps

 

By the way, I love that Alex has a dislike for the Adjustable nut rounders! (like myself) The video got my like for that part it's self!!

 

If you do this and after it is all said and done, you could send the pumps down to me and I can use them on my project vehicle! LoL

Unfortunately, due to legal issues, we had to do it on the moon... Or so they thought.

So you guys glossed over the results.  What was the rig you were running?  Did it actually improve things?  What were the thresholds for diminishing returns?  How did the 2 horse power water pump compare to the X horse power blowers that you used a while ago?

Kind of disingenuous using a 40 gallon bucket of chilled water - heck you could have bought that much distilled bottled water from a couple of stores and not had to deal with cleaning/filtering.

 

It's not so much the flow rate that's lowering the temps here but the sheer volume of water - the more coolant you have by volume the harder it is to heat it up. Put it another way, it will soak up your systems heat and carry it away more efficiently. I have a full gallon circulating inside my loop cooling five blocks using chunky 80mm thick rads in push/pull. My res isn't a particularly big one since I had to cram it inside a 200mm space, but had I gone external with a longer 400mm one I could have gotten even more coolant. Same can be done with a split loop using two large external reservoirs - if the room temperature is set at a cool 19C your deltas will be well under 25C as well. I often sit in a 30C room (32C right now actually) and I can still run my rig at full tilt (54C on the CPU and 55C on my GPU's). In my case (no pun intended) it's the WATER TEMP that is the primary measurement which always stays below the rated pump max at 60C. Right now that water temp is 48C resulting in just a 16C delta over ambient - that's the hallmark of a well designed and well cooled system.

 

Dual pumps are another trick that you can employ and connecting them in series can increase head pressure - ideal for very tall builds with many bends/blocks in them, thinner diameter fittings/tubing and situations where a single D5 may be overwhelmed. My build is not excessively tall, I'm using the largest diameter tubing (7/16), only a single 90 degree fitting and I only have a single cooling chamber (pedestal) at the base, not top and bottom. The 2nd pump also works as a fail safe should one pump not get power or the bearings fail and quit working. For a parallel connection to increase flow rate you would use separate dual loops instead. It's not impossible to build a system with as many as FOUR separate loops each going to a large external reservoir, 8 pumps for redundancy, and probably more like 2 to 3 gallons of total coolant.

 

Finally. this is also a great reminder why you should never push those pathetic budget AIO coolers - much weaker pumps with lower flow rates and lower temperature limits. That last part is what kills them prematurely because the volume of coolant they have to work with is very minimal. I wouldn't be surprised if the actual liquid temps inside an AIO exceed 60C. It may not die immediately, but it WILL die sooner than you think.

 

Here's a great video idea for Alex - attach a water temp sensor to some AIO coolers and see just how hot they get. I can guarantee some of them will be going beyond their pump temperature limit.

This is something i would have done at the hut i have in the mountains.. Im glad you guys test this out before i try with my own diesel generator..

The *only* time I've exploded something watercooling is when I put 3 D5 pumps in series in my loop.  It blew the tube off the barb even with a plastic hose clamp on it.  You've never seen me dive faster for the power switch as it's water-fountaning into my side panel.

 

(actually I lied, the other time I exploded something was when I was using compressed air to drain my loop and forgot to open the other end of the loop.  The o-ring on my reservoir fortunately blew out instead of the whole thing grenading)...it's still a valid strategy that not many people know about though for draining a complex  loop quick.

 

EDIT EDIT: Actually I remembered the 3rd time.  I sealed up a loop that I intentionally took up to 70C water temperature.  Water expands slightly when it's hot and I had gallons of volume so it ended up ballooning out the end of a radiator like hydroforming.  From that I learned I need an entire reservoir worth of air as a buffer for the expansion, cause air is compressible and water isn't.

Reducing the pipe sizes that much is absurd. The water will be so turbulent that you would be well past diminishing returns.

 

What I mean is the resistance the pump experiences is a function of bends and uneven changes in the line, along with friction of water against the 'rough' pipes. 

This is however much greater when the water is turbulent, hence why the small D5 pump was doing well, the flow was less turbulent as such there was less resistance to allow good flow.

 

A much nicer approach maybe for a next video is using an electric pump (quiet and also you could do it indoors) also custom bigger tubes with custom cpu/gpu blocks plates would be so much better

Overkill much? This is what you would use for a project such as 'Whole Office Building Cooling' Save for the fact that you probably don't want to buy gas that often.

In search of the future, new tech, and exploring the universe! All under the cover of anonymity!

The original pump in the loop made me wonder, whether you could use it to generate electricity and power the computer. I guess the water cooling pumps are not sized for that.
But it should be feasible to only provide pressurized water (or oil) to a computer, generate the electricity to power the PC, and use the fluid for cooling.

It's not disingenuous at all. We used the same chilled water at low and high pump speeds.

So repeat the test using ambient/room temperature water - the pump speed will have even less effect. A D5 running at 80% (#4 on the pot) will do 317 gal/hr or a little over 5 gallons per minute. That will circulate the entire 1 gallon coolant volume in my rig every 12 seconds, and typically well under that on the average (smaller) build. Your ghetto setup assuming that is a 40 gallon bucket would take an entire minute to circulate through. Not only does the water temperature take longer to equalize but it becomes impossible to measure a water temperature difference based on the heat load. Again you're using chilled water to remove the heat rather than allowing the components to push the water temperature above ambient - pump speed becomes irrelevant. And assuming that really was chilled water you then introduce condensation issues... but I don't care at this point. You do whatever you need to for those $$$ YouTube views.
