Which is the better choice? (D5 Pump) - Page 3

post #21 of 23
I def understand what you are saying about just setting it and leaving it. It makes complete sense especially if the system is running at 100% or completely off all the time. But then you bring the word comfortable in the picture and something does change. If the computer is being used for a wide range of things then comfortable can be different for different situations. What if the user is only "comfortable" all the time at a low setting. I don't see any reason to not run the pump at 100% or close to it when benching or stability testing but not for anything else. So if someone is listening to music on their computer why would they want the pump running at 100% or 80% or whatever besides the minimum needed to keep the CPU and GPU running cool.

I see your point that there is one MAJOR disadvantage to PWM and that is that you can't buy the D5 Strong. But if you are not going to buy the D5 strong at all then what is the advantage to not getting the PWM pump? Besides a small amount of money or maybe a tiny difference in performance at certain RPM if any difference.

Our loops are all WILDLY different from each others. Different blocks, radiators, reservoirs, etc. Having a PWM controlled pump allows you to fine tune it at the least and then like you said just leave it at that speed... but it also gives you the ability to run it out full blast when doing stability tests or encoding and then run it at a much lower speed any other time.

On my computer running a single 35x at the lowest vs the highest setting does not affect my GPU or CPU idle temps by a noticeable amount. I have one of or the least restrictive CPU block out there and my GPU block is not specifically known to be restrictive so no surprise that at a low duty I don't see any problems. It is no surprise to me that someone that is running GPU blocks in parallel would see an increase in temps at the lowest PWM setting because now we are talking about half the flow of an already reduced flow to begin with but even then that person has so much control over the speed of the pump that they can make the minimum speed whatever they want and make the max speed whatever they want.

I would hope that anyone could see the benefit to that in any situation except the computer always being used with the exact same load.

In a computer that always ran the same load all the time you still have the advantage of refined speed control and the ability to adjust the speed if needed even if the pump is mounted in a place that on a vario would make it difficult or impossible to get to.

thank you Friends.I'm a beginner

my loop Now: cpu waterblock xspc raystorm . vga waterblock. heat killer _GPU-X_79X0 . rad 2*triple alphacool . reservoir Bitspower_Water_Tank_Z-Multi_250

Whether one d5 pump is strong enough for my loop??

Yes, one D5 is enough, but I would add a top.
